Safety Precautions
• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be
provided to ensure safety in the system.
• The PLC or outputs may remain ON or OFF due to deposits on or burning
of the output relays, or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided
to ensure safety in the system.
• When the 24-V DC output (service power supply to the PLC) is overloaded or short-circuited, the voltage may drop and result in the outputs
being turned OFF. As a countermeasure for such problems, external
safety measures must be provided to ensure safety in the system.
!WARNING Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Not doing so may result in
serious accidents.
!WARNING Do not apply the voltage/current outside the specified range to this unit. It may
cause a malfunction or fire.
!Caution Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be
readable.
!Caution Confirm safety at the destination node before transferring a program to
another node or editing the I/O area. Doing either of these without confirming
safety may result in injury.
!Caution Tighten the screws on the terminal block of the AC power supply to the torque
specified in this manual. The loose screws may result in burning or malfunction.
!Caution Do not touch anywhere near the power supply parts or I/O terminals while the
power is ON, and immediately after turning OFF the power. The hot surface
may cause burn injury.
!Caution Pay careful attention to the polarities (+/-) when wiring the DC power supply. A
wrong connection may cause malfunction of the system.
!Caution When connecting the PLC to a computer or other peripheral device, either
ground the 0 V side of the external power supply or do not ground the external

!Caution After programming (or reprogramming) using the IOWR instruction, confirm
that correct operation is possible with the new ladder program and data before
starting actual operation. Any irregularities may cause the product to stop
operating, resulting in unexpected operation in machinery or equipment.
!Caution The CP1L CPU Units automatically back up the user program and parameter
data to flash memory when these are written to the CPU Unit. I/O memory
(including the DM Area, counter present values and Completion Flags, and
HR Area), however, is not written to flash memory. The DM Area, counter
present values and Completion Flags, and HR Area can be held during power
interruptions with a battery. If there is a battery error, the contents of these
areas may not be accurate after a power interruption. If the contents of the
DM Area, counter present values and Completion Flags, and HR Area are
used to control external outputs, prevent inappropriate outputs from being
made whenever the Battery Error Flag (A402.04) is ON.

these precautions.
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.
• Mount the Unit only after checking the connectors and terminal blocks
completely.
• Be sure that all the terminal screws and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening
torque may result in malfunction.
• Wire all connections correctly according to instructions in this manual.
• Always use the power supply voltage specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction.
• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.
• Do not apply voltages to the input terminals in excess of the rated input
voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the output terminals in excess
of the maximum switching capacity. Excess voltage or loads may result in
burning.
xxvii
5
Application Precautions
• Be sure that the terminal blocks, connectors, Option Boards, and other
items with locking devices are properly locked into place. Improper locking
may result in malfunction.
• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.
• Wire correctly and double-check all the wiring or the setting switches
before turning ON the power supply. Incorrect wiring may result in burning.
• Check that the DIP switches and data memory (DM) are properly set
before starting operation.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected operation.
• Resume operation only after transferring to the new CPU Unit the contents of the DM, HR, and CNT Areas required for resuming operation. Not
doing so may result in an unexpected operation.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PLC (including the setting of the
startup operating mode).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.
• Do not place objects on top of the cables. Doing so may break the cables.
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• Before touching the Unit, be sure to first touch a grounded metallic object
in order to discharge any static buildup. Not doing so may result in malfunction or damage.
• Do not touch the Expansion I/O Unit Connecting Cable while the power is
being supplied in order to prevent malfunction due to static electricity.
• Do not turn OFF the power supply to the Unit while data is being transferred.
• When transporting or storing the product, cover the PCBs and the Units or
put there in the antistatic bag with electrically conductive materials to prevent LSls and ICs from being damaged by static electricity, and also keep
the product within the specified storage temperature range.
• Do not touch the mounted parts or the rear surface of PCBs because
PCBs have sharp edges such as electrical leads.
• Double-check the pin numbers when assembling and wiring the connectors.
• Wire correctly according to specified procedures.
• Do not connect pin 6 (+5V) on the RS-232C Option Board (CP1W-CIF01)
on the CPU Unit to any external device other than the NT-AL001 or
CJ1W-CIF11 Conversion Adapter. The external device and the CPU Unit
may be damaged.
xxviii
Application Precautions
5
• Use the dedicated connecting cables specified in this manual to connect
the Units. Using commercially available RS-232C computer cables may
cause failures in external devices or the CPU Unit.
• The user program and parameter area data in the CPU Unit is backed up
in the built-in flash memory. The BKUP indicator will light on the front of
the CPU Unit when the backup operation is in progress. Do not turn OFF
the power supply to the CPU Unit when the BKUP indicator is lit. The data
will not be backed up if power is turned OFF.
• Do not turn OFF the power supply to the PLC while the Memory Cassette
is being written. Doing so may corrupt the data in the Memory Cassette.
The BKUP indicator will light while the Memory Cassette is being written.
Wait for the BKUP indicator to go out before turning OFF the power supply to the PLC.
• Before replacing the battery, supply power to the CPU Unit for at least 5
minutes and then complete battery replacement within 5 minutes of turn
OFF the power supply. Memory data may be corrupted if this precaution is
not observed.
• Always use the following size wire when connecting I/O terminals:
AWG22 to AWG18 (0.32 to 0.82 mm2).
• Dispose of the product and batteries according to local ordinances as
they apply.
Have qualified specialists properly dispose of used batteries as industrial
waste.
• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries. Also,
always follow the replacement procedure provided in the manual.
• Never short-circuit the positive and negative terminals of a battery or
charge, disassemble, heat, or incinerate the battery. Do not subject the
battery to strong shocks or deform the barry by applying pressure. Doing
any of these may result in leakage, rupture, heat generation, or ignition of
the battery. Dispose of any battery that has been dropped on the floor or
otherwise subjected to excessive shock. Batteries that have been subjected to shock may leak if they are used.
• Always construct external circuits so that the power to the PLC it turned
ON before the power to the control system is turned ON. If the PLC power
supply is turned ON after the control power supply, temporary errors may
result in control system signals because the output terminals on DC Output Units and other Units will momentarily turn ON when power is turned
ON to the PLC.
• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.
• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be
turned OFF and will maintain their previous status when the PLC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(007) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)

Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.
Note
The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).
6-3
Conformance to EC Directives
The CP1L PLCs comply with EC Directives. To ensure that the machine or
device in which the CP1L PLC is used complies with EC Directives, the PLC
must be installed as follows:
1,2,3...
1. The CP1L PLC must be installed within a control panel.
2. You must use reinforced insulation or double insulation for the DC power
supplies used for I/O Units and CPU Units requiring DC power. The output
holding time must be 10 ms minimum for the DC power supply connected
to the power supply terminals on Units requiring DC power.
3. CP1L PLCs complying with EC Directives also conform to EN61131-2. Radiated emission characteristics (10-m regulations) may vary depending on
the configuration of the control panel used, other devices connected to the
control panel, wiring, and other conditions. You must therefore confirm that
the overall machine or equipment complies with EC Directives.

of the EMC Directives. However, noise generated by relay output switching
may not satisfy these Standards. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the PLC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.

Countermeasures
Countermeasures are not required if the frequency of load switching for the
whole system with the PLC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system with the PLC included is more than 5 times per minute.
Note
Refer to EN61131-2 for more details.

When switching an inductive load, connect an surge protector, diodes, etc., in
parallel with the load or contact as shown below.

If the load is a relay or solenoid, there is
a time lag between the moment the circuit is opened and the moment the load
is reset.
If the supply voltage is 24 or 48 V, insert
the surge protector in parallel with the
load. If the supply voltage is 100 to
200 V, insert the surge protector
between the contacts.
The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from experiments, and take into consideration that
the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the
current that flows into the load when
the circuit is closed again.
The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.

The varistor method prevents the impo- --sition of high voltage between the contacts by using the constant voltage

Features and Main Functions
Positioning with an
Inverter
Positioning can be controlled using an inverter. Previously, an internal pulse
output with trapezoidal acceleration/deceleration is created using the PULSE
OUTPUT instruction. The position offset is calculated using an error counter
for the feedback pulse input from a rotary encoder connected to an inductive
motor and the internal pulse output. The error counter is then used to output a
speed command to the inverter to control positioning. This enables positioning
with high-capacity motors, as well as low-cost positioning with small-capacity
motors (in comparison to using a servo).
A virtual pulse output is created using a pulse output instruction, the position
offset is calculated using an error counter, and a frequency (i.e., speed)
command is output according to the position offset to control positioning.

Functions
If high-precision positioning is required, we recommend using an inverter with

High-speed counter inputs can be enabled by connecting rotary encoders to
the built-in inputs. The ample number of high-speed counter inputs makes it
possible to control a multi-axis device with a single PLC.
• Four 100-kHz (single phase)/50-kHz (differential phases) high-speed
counter inputs (4 counters/2 axes) are provided as a standard feature.
(See note.)
• For CP1L-J PLCs, four 20-kHz (single phase)/10-kHz (differential phases)
high-speed counter inputs (4 counters/2 axes) are provided as a standard

High-speed Processing for High-speed Counter Present Value (PV)
Target Values or Range Comparison Interrupts
An interrupt task can be started when the count reaches a specified value or
falls within a specified range.
High-speed Counter Input Frequency (Speed) Monitoring
The input pulse frequency can be monitored using the PRV instruction (one
point (counter 0) only, and you must select whether to use input frequency
monitoring or counter 3; you cannot use both).
High-speed Counter PV Holding/Refreshing
It is possible to toggle between holding and refreshing the high-speed counter
PV by turning ON and OFF the High-speed Counter Gate Flag from the ladder
program.
Versatile Pulse
Control (CPU Units
with Transistor
Outputs Only)
Positioning and speed control by a pulse-input servo driver is enabled by outputting fixed duty ratio pulse output signals from the CPU Unit's built-in outputs.
• Pulse outputs for 2 axes at 100 kHz maximum are provided as standard
features. (See note.)
• For CP1L-J PLCs, pulse outputs for 2 axes at 20 kHz maximum are provided as standard features. (See note.)

The pulse outputs can be selected to match the pulse input specifications of

Easy Positioning with Absolute Coordinate System Using Automatic
Direction Setting
For operations in an absolute coordinate system (i.e., when the origin is
established or when the PV is changed by the INI instruction), the CW/CCW
direction can be automatically set when PULSE OUTPUT instructions are
executed according to whether the specified number of output pulses is more
or less than the pulse output PV.

Features and Main Functions
Section 1-1
Triangular Control
If the amount of output pulses required for acceleration and deceleration (the
target frequency times the time to reach the target frequency) exceeds the
preset target number of output pulses during positioning (when the ACC
instruction in independent mode or the PLS2 instruction is executed), the
acceleration and deceleration will be shortened and triangular control will be
executed instead of trapezoidal control. In other words, the trapezoidal pulse
output will be eliminated, with no period of constant speed.
Target Position Changes during Positioning (Multiple Start)
While positioning using a PULSE OUTPUT (PLS2) instruction is in progress,
the target position, target speed, acceleration rate, and deceleration rate can
be changed by executing another PLS2 instruction.
Positioning Changes during Speed Control (Interrupt Feeding)
While speed control in continuous mode is in effect, it is possible to change to
positioning in independent mode by executing a PULSE OUTPUT (PLS2)
instruction. By this means, interrupt feeding (moving a specified amount) can
be executed under specified conditions.
Target Speed, Acceleration Rate, and Deceleration Rate Changes during
Acceleration or Deceleration
When a PULSE OUTPUT instruction with trapezoidal acceleration and deceleration is executed (for speed control or positioning), the target speed and
acceleration and deceleration rates can be changed during acceleration or
deceleration.
Lighting and Power Control by Outputting Variable Duty Ratio Pulses
Operations, such as lighting and power control, can be handled by outputting
variable duty ratio pulse (PWM) output signals from the CPU Unit's built-in
outputs.
Origin Searches
Origin Search and Origin Return Operations Using a Single Instruction
An accurate origin search combining all I/O signals (origin proximity input signal, origin input signal, positioning completed signal, error counter reset output, etc.) can be executed with a single instruction. It is also possible to move
directly to an established origin using an origin return operation.
Input Interrupts
In direct mode, an interrupt task can be started when a built-in input turns ON
or OFF. In counter mode, the rising or falling edges of built-in inputs can be
counted, and an interrupt task started when the count reaches a specified
value. The maximum number of interrupt input points is 6 for CPU Units with
20, 30, 40 or 60 I/O points and 4 for CPU Units with 14 I/O points and 2 for
CPU Units with 10 I/O points.
Note
Quick-response
Inputs
10
For each input point, a selection in the PLC Setup determines whether it is to
be used as a normal input, interrupt input, quick-response input, or highspeed counter. The interrupt input response frequency in counter mode must
be 5 kHz or less total for all interrupts.
By using quick-response inputs, built-in inputs up to a minimum input signal
width of 50 µs can be read regardless of the cycle time. The maximum number of quick-response input points is 6 for CPU Units with 20, 30, 40 or 60 I/O
points and 4 for CPU Units with 14 I/O points and 2 for CPU Units with 10 I/O
points.

Features and Main Functions
Note
For each input, a PLC Setup parameter determines whether it is to be used as
a normal input, interrupt input, quick-response input, or high-speed counter.
Analog Settings
Changing Settings Using
Analog Adjustment
By adjusting the analog adjuster with a Phillips screwdriver, the value in the
Auxiliary Area can be changed to any value between 0 and 255. This makes it
easy to change set values such as timers and counters without Programming
Devices.

Inputs
External analog values of 0 to 10 V (resolution: 256) are converted to digital
values and stored in a word in the AR Area. This enables applications that
require on-site adjustment of settings that do not demand a particularly high
degree of accuracy, such as for example, a setting based on changes in outdoor temperatures or potentiometer inputs.

When a voltage (0 to 10 V) is input from a
device such as a potentiometer to the
external analog setting input, the PV in A643
is refreshed between 0000 and 0100 hex (0
to 256).
Example: The production quantity could be changed by changing
the timer set value from 100 to 150.

No-battery Operation
Programs, the PLC Setup, and other data can be automatically saved to the
CPU Unit's built-in flash memory. Moreover, DM Area data can be saved to
the flash memory and then used as initial data when the power is turned ON.
This allows programs and initial values (such as recipe setup data) in the DM
Area to be saved in the CPU Unit without the need to maintain a backup battery.

Function Blocks

Function Blocks
Function blocks can be used in programming SYSMAC CP-series PLCs.
Note
1-5-1
Function blocks cannot be used in CP1L-J PLCs.
Overview of Function Blocks
A function block is a basic program element containing a standard processing
function that has been defined in advance. Once the function block has been
defined, the user just has to insert the function block in the program and set
the I/O in order to use the function.
As a standard processing function, a function block is not created with actual
physical addresses, but local variables. The user sets parameters (addresses
or values) in those variables to use the function block. The addresses used for
the variables themselves are automatically assigned by the system (CX-Programmer) each time they are placed in the program.
In particular, each function block is saved by the CX-Programmer as an individual file that can be reused with programs for other PLCs. This makes it possible to create a library of standard processing functions.

Advantages of Function Blocks
Function blocks allow complex programming units to be reused easily. Once
standard program sections have been created as function blocks and saved in
files, they can be reused just by placing a function block in a program and setting the parameters for the function block's I/O. Reusing standardized function
blocks reduces the time required for programming/debugging, reduces coding
errors, and makes programs easier to understand.
Structured
Programming
34
Structured programs created with function blocks have better design quality
and required less development time.
Section 1-5
Function Blocks
Easy-to-read “Block Box”
Design
The I/O operands are displayed as local variable names in the program, so
the program is like a “black box” when entering or reading the program and no
extra time is wasted trying to understand the internal algorithm.
Different Processes Easily
Created from a Single
Function Block
Many different processes can be created easily from a single function block by
using input variables for the parameters (such as timer SVs, control constants, speed settings, and travel distances) in the standard process.
Reduced Coding Errors
Coding mistakes can be reduced, because blocks that have already been
debugged can be reused.
Data Protection
The local variables in the function block cannot be accessed directly from the
outside, so the data can be protected. (Data cannot be changed unintentionally.)
Improved Reusability
through Programming
with Variables
The function block's I/O is entered as local variables, so the data addresses in
the function block do not have to be changed as they do when copying and
reusing a program section.
Creating Libraries
Processes that are independent and reusable (such as processes for individual steps, machinery, equipment, or control systems) can be saved as function block definitions and converted to library functions.
The function blocks are created with local variable names that are not tied to
physical addresses, so new programs can be developed easily just by reading
the definitions from the file and placing them in a new program.
Nesting Multiple
Languages
Mathematical expressions can be entered in structured text (ST) language.
Nesting function blocks is supported for CX-Programmer Ver. 6.0 or higher.
For example, it is possible to express only special operations in ST language
within a function block in a ladder diagram.

Specifications
Note
(1) The above values are for a cold start at room temperature for an AC power supply, and for a cold start for a DC power supply.
• A thermistor (with low-temperature current suppression characteristics) is used in the inrush current control circuitry for the AC power supply. The thermistor will not be sufficiently cooled if the ambient
temperature is high or if a hot start is performed when the power supply has been OFF for only a short time, so in those cases the inrush
current values may be higher (as much as two times higher) than those
shown above.
• A capacitor delay circuit is used in the inrush current control circuitry
for the DC power supply. The capacitor will not be charged if a hot start
is performed when the power supply has been OFF for only a short
time, so in those cases the inrush current values may be higher (as
much as two times higher) than those shown above.
Always allow for this when selecting fuses and breakers for external circuits.
(2) Use the external power supply to power input devices. Do not use it to
drive output devices.
(3) This is the rated value for the maximum system configuration. Use the following formula to calculate DC power consumption for CPU Units with DC
power.
Formula:
DC-powered CP1L power consumption = 5-V current consumption × 5 V/
70% (CP1L internal power efficiency) + 24-V current consumption × 1.1
(current fluctuation factor)

User programs and parameters (such as the PLC Setup) are automatically saved to the flash
memory. It is also possible to save and read data memory initial data.
The data is automatically transferred to RAM when the power supply is turned ON. (Data memory
initial data, however, may or may not be transferred, depending on the selection in the PLC Setup.
The HR Area, DM Area, and counter values (flags, PV) are backed up by a battery.
Battery model: CJ1W-BAT01 (Built into the CP1L CPU Unit.)
Maximum battery service life: 5 years
Guaranteed (ambient temperature: 55°C): 13,000 hours (approx. 1.5 years)
Effective value (ambient temperature: 25°C): 43,000 hours (approx. 5 years)
A CP1W-ME05M Memory Cassette (512K words, optional) can be mounted. It can be used to
back up the following data on the CPU Unit's RAM and to transfer the data at startup.
• Data saved on Memory Cassette: User programs, parameters (such as the PLC Setup), DM
Area, data memory initial data, comment memory (CX-Programmer conversion tables, comments, program indices), and FB program memory.
• Writing to Memory Cassette: By operations from the CX-Programmer.
• Reading from Memory Cassette: At startup, or by operations from the CX-Programmer.
Memory Cassette cannot be used in CP1L-J CPU Unit.
Note
Can be used as Modbus-RTU easy master function.

• Data is backed up from RAM to the built-in flash memory when
changes are made, e.g., from the CX-Programmer.
• When the power supply is turned ON, data is transferred from the builtin flash memory to RAM.
(2)
• A CX-Programmer operation can be used to transfer DM Area initial
values from RAM to the built-in flash memory.
• The PLC Setup can be set so that DM Area initial values are transferred from the built-in flash memory to RAM when the power supply
is turned ON.
(3)
• CX-Programmer operations can be used to transfer data from RAM to
the Memory Cassette or from the built-in flash memory to the Memory
Cassette.
73
Section 2-3
CP1L CPU Unit Operation
• When the power supply is turned ON, data is transferred from the
Memory Cassette to the built-in flash memory and RAM. Data can also
be transferred from the Memory Cassette to the built-in flash memory
and RAM using the CX-Programmer.
User Program
The user program consists of up to 288 tasks, including interrupt tasks. Each
task is programmed from the CX-Programmer and then transferred to the
CPU Unit.
There are two types of tasks: cyclic tasks and interrupt tasks. Cyclic tasks are
executed once each cycle and interrupt tasks are executed only when the
interrupt conditions are met. There can be up to 32 cyclic tasks and up to 256
interrupt tasks. Cyclic tasks are executed in the order of the task numbers.
Instructions programmed in the tasks are executed in order from the first
instruction and then I/O memory is refreshed. When all cyclic tasks have been
executed, I/O refreshing with PLC Units is performed and then the cyclic tasks
are executed again starting from the one with the lowest task number. This is
called the cyclic scan method.
I/O Memory
The I/O memory area is a RAM area read and written by the user. Some parts
of the I/O memory are cleared when the power is interrupted. Other parts are
maintained. There are parts that used for data exchange with PLC Units and
parts that are used internally.
There are two ways to refresh the parts of I/O memory used for data
exchange with PLC Units: Once each program execution cycle and immediately when needed when executing specific instructions.
Parameter Area
In addition to the I/O memory used as instructions operands by the user, there
is also a separate memory area that can be manipulated only from the CXProgrammer. This area, called the parameter area, contains the following.
• PLC Setup
• Routing tables
PLC Setup
74
The PLC Setup contains configuration parameters that can be set by the user
to define the basic specifications of the CPU Unit. Included are serial port settings, a minimum cycle time setting, and other parameters. For details, refer to
the CX-Programmer Operation Manual.
Section 2-3
CP1L CPU Unit Operation
Routing Tables
Tables specifying the communications paths from the Communications Units
on the local PLC to remote PLCs connected on other networks must be registered in all the CPU Units in network PLCs to send and receive data between
networks. These tables are called the routing tables. The routing tables consist of the relay network table and local network table.
Routing tables are created from the CX-Programmer or Support Software for
Communications Units (e.g., CX-Integrator) and then transferred to each CPU
Unit.

The remote network tables lists the node number and network address of the
first relay node that must be passed through to reach any remote network to
which the PLC is not directly connected. Once the routing tables have been
registered, any remote network can be reached by passing through relay
nodes.
Local Network Table
The local network table contains the unit number and network address of all
Communications Units that are part of the local PLC.
Built-in Flash Memory
Flash memory is built into the CP1L CPU Units. Data in the following areas is
automatically backed up to the flash memory whenever it is written in any way
other than by instructions in the user program, e.g., when the CX-Programmer
or PT is used to transfer or edit data, edit the program online, or transfer data
from a Memory Cassette.
• User program area
• Parameter area (PLC Setup and routing tables)
The next time the power supply is turned ON, the data in the built-in flash
memory is automatically transferred to user memory (i.e., the user program
area and parameter area).
It is also possible to save data from data areas in I/O memory in the built-in
flash memory using operations from the CX-Programmer.
The symbol table, comment file, and program index file can be stored in the
comment memory in flash memory. When the program is transferred from the
CX-Programmer to the CPU Unit, function block program information is also
stored automatically in flash memory.
Note
The BKUP indicator on the front of the CPU Unit will light whenever the built-in
flash memory is being written or the Memory Cassette is being accessed.
75
Section 2-3
CP1L CPU Unit Operation
Never turn OFF the power supply to the CPU Unit when the BKUP indicator is
lit.
Memory Cassette
Memory Cassettes can be used as required in system operation and maintenance. For example, they can be used to save programs, data memory contents, PLC Setup data, or I/O comments from the CX-Programmer. The
contents of a Memory Cassette can also be automatically transferred if
desired.
Note
76
Memory Cassette cannot be used in CP1L-J CPU Unit.

I/O Refreshing and Peripheral Servicing
I/O Refreshing
I/O refreshing involves cyclically transferring data with external devices using
preset words in memory. I/O refreshing includes the following:
• Refreshing between I/O words in the CIO Area and CPU Unit built-in I/O,
CP/CPM1A-series Expansion Units, and CP/CPM1A-series Expansion
I/O Units
All I/O refreshing is performed in the same cycle (i.e., time slicing is not used).
I/O refreshing is always performed after program execution.

Peripheral Servicing
Peripheral servicing involves servicing non-scheduled events for external
devices. This includes both events from external devices and service requests
to external devices.
Most peripheral servicing involves FINS commands. The specific amount of
time set in the system is allocated to each type of servicing and executed
every cycle. If all servicing cannot be completed within the allocated time, the
remaining servicing is performed the next cycle.
Service
USB port servicing
Communications port servicing
Description
• Non-scheduled servicing for FINS or Host Link
commands received via a USB port or serial port
from the CX-Programmer, PTs, or host computers
(e.g., requests for program transfers, monitoring,
forced-set/reset operations, or online editing)
• Non-scheduled servicing from the CPU Unit transmitted from a serial port (non-solicited communications)
Communications port servicing
• Servicing to execute network communications or
serial communications for the SEND, RECV, CMND
or PMCR instructions using communications ports

Note
2-4-3
Peripheral USB port, serial port, and communications port servicing is allocated 8% of the previous cycle time by default (the default can be changed)
for each service. If servicing is separated over many cycles, delaying completion of the servicing, set the same allocated time (same time for all services)
rather than a percentage under execute time settings in the PLC Setup.
I/O Refresh Methods
I/O for CPU Unit built-in I/O and I/O on CP/CPM1A-series Expansion Units
and Expansion I/O Units is performed at the following times.
1,2,3...
1. Cyclic refresh period
2. When instructions with an immediate refresh variation are executed
3. When IORF(097) is executed

Note
(1) Immediate refreshing is possible only for the Built-in I/O Area. Use
IORF(097) for I/O on CP/CPM1A-series Expansion Units and Expansion
I/O Units.
(2) Refreshing Range
• Bit Operands
The ON/OFF status of the 16 I/O points allocated to the word containing the specified bit will be refreshed.
• Word Operands
The ON/OFF status of the 16 I/O points allocated to the specified word
will be refreshed.
(3) Refresh Timing
• Input or source operands are read just before the instruction is executed.
• Output or destination (results) operands are written just after the instruction is executed.
(4) Using instructions with the immediate refresh option, instruction execution time will be increased, increasing the overall cycle time. Be sure to
confirm that this will not adversely affect system operation.
IORF(097) Refreshing
When IORF(097) (I/O REFRESH) is executed, the I/O bits in the specified
range of words are refreshed. IORF(097) can be used for CP/CPM1A-series
Expansion Units and CP/CPM1A-series Expansion I/O Units.

If high-speed response is required from input to output, execute IORF(097)
before and after the relevant instructions.
Note
2-4-4
IORF(097) has a relatively long execution time which increases with the number of words being refreshed. Be sure to consider the affect of this time on the
overall cycle time. Refer to the CP Series Programmable Controllers Programming Manual for instruction execution times.

Computing the Cycle Time
2-7-2
Cycle Time Overview
The cycle time depends on the following conditions.
• Type and number of instructions in the user program (in all cyclic tasks
that are executed during a cycle, and within interrupt tasks for which the
execution conditions have been satisfied)
• Type and number of CP/CPM1A-series Expansion Units and Expansion I/
O Units
• Use of protocol macros and the largest communications message
• Fixed cycle time setting in the PLC Setup
• Use of USB and serial ports
• Fixed peripheral servicing time in the PLC Setup
Note
1. The cycle time is not affected by the number of tasks that are used in the
user program. The tasks that affect the cycle time are those cyclic tasks
that are READY in the cycle.
2. When the mode is switched from MONITOR mode to RUN mode, the cycle
time will be extended by 10 ms (this will not, however, take the cycle time
over its limit).
The cycle time is the total time required for the PLC to perform the five operations given in the following tables.

Online Editing Cycle Time Extension
When online editing is executed to change the program from the CX-Programmer while the CPU Unit is operating in MONITOR mode, the CPU Unit will
momentarily suspend operation while the program is being changed. The
period of time that the cycle time is extended is determined by the following
conditions.
• Number of steps changed
• Editing operations (insert/delete/overwrite)
• Types of instructions
The cycle time extension for online editing is negligibly affected by the size of
task programs. If the maximum program size for a task is 10 Ksteps, the
online editing cycle time extension will be as follows:
CPU Unit
CP1L CPU Unit
Increase in cycle time for online editing
Maximum: 16 ms, Normal: 12 ms
(for a program size of 10 Ksteps)
When editing online, the cycle time will be extended by according to the editing that is performed. Be sure that the additional time will not adversely affect
system operation.
Note When there is one task, online editing is processed all in the cycle time following the cycle in which online editing is executed (written). When there are multiple tasks (cyclic tasks and interrupt tasks), online editing is separated, so
that for n tasks, processing is executed over n to n ×2 cycles max.

The I/O response time is the time it takes from when an input turns ON, the
data is recognized by the CPU Unit, and the user program is executed, up to
the time for the result to be output to an output terminal. The length of the I/O
response time depends on the following conditions.
• Timing of Input Bit turning ON.
• Cycle time.
Minimum I/O
Response Time
The I/O response time is shortest when data is retrieved immediately before I/
O refresh of the CPU Unit. The minimum I/O response time is calculated as
follows:
Minimum I/O response time = Input ON delay + Cycle time + Output ON delay
Note The input and output ON delays depend on the type of terminals used on the
CPU Unit or the model number of the Unit being used.

Maximum I/O response time = 1 ms + (20 ms × 2) + 0.1 ms = 41.1 ms
Input Response
Times
Input response times can be set in the PLC Setup. Increasing the response
time reduces the effects of chattering and noise. Decreasing the response
time allows reception of shorter input pulses, (but the pulse width must be
longer than the cycle time).
Input response time
The pulse width is
less than the input
response time, so
it is not detected.

Interrupt Response Times
Input Interrupt Tasks
The interrupt response time for I/O interrupt tasks is the time taken from when
a built-in input has turned ON (or OFF) until the I/O interrupt task has actually
been executed. The length of the interrupt response time for I/O interrupt
tasks depends on the following conditions.

--Minimum: 236 µs
Maximum: 234 µs + Wait

Maximum: 336 µs + Wait time
(See note1.)
(1) The wait time occurs when there is competition with other interrupts. As
a guideline, the wait time will be 6 to 169 µs.
(2) I/O interrupt tasks can be executed during execution of the user program
(even while an instruction is being executed by stopping the execution of
an instruction), I/O refresh, peripheral servicing, or overseeing. The interrupt response time is not affected by which of the above processing operations during which the interrupt inputs turns ON. I/O interrupts,
however, are not executed during execution of other interrupt tasks even
if the I/O interrupt conditions are satisfied. Instead, the I/O interrupts are

The time from completing the ladder program in the input

Scheduled Interrupt Tasks
The interrupt response time of scheduled interrupt tasks is the time taken
from after the scheduled time specified by the MSKS(690) instruction has
elapsed until the interrupt task has actually been executed. The length of the
interrupt response time for scheduled interrupt tasks is 1 ms max. There is
also an error of 80 µs in the time to the first scheduled interrupt (0.5 ms min.).
Note Scheduled interrupt tasks can be executed during execution of the user program (even while an instruction is being executed by stopping the execution of
an instruction), I/O refresh, peripheral servicing, or overseeing. The interrupt
response time is not affected by which of the above processing operations
during which the scheduled interrupt time occurs. Scheduled interrupts, however, are not executed during execution of other interrupt tasks even if the
interrupt conditions are satisfied. Instead, the interrupts are executed in order
of priority after the current interrupt task has completed execution and the
software interrupt response time has elapsed.

Serial PLC Link Response Performance
The response times for CPU Units connected via a Serial PLC Link (master to
slave or slave to master) can be calculated as shown below. If a PT is in the
Serial PLC Link, however, the amount of communications data will not be
fixed and the values will change.
• Maximum I/O response time (not including hardware delay) =
Master cycle time + Communications cycle time + Slave cycle time + 4 ms
• Minimum I/O response time (not including hardware delay) =
Slave communications time + 0.8 ms

Section 3-1
Fail-safe Circuits
3-1
Fail-safe Circuits
Always set up safety circuits outside of the PLC to prevent dangerous conditions in the event of errors in the CP1L CPU Unit or external power supply. In
particular, be careful of the following points.
Supply Power to the
CP1L CPU Unit before
the Controlled
System
If the PLC's power supply is turned ON after the controlled system's power
supply, outputs in Units such as DC Output Units may malfunction momentarily. To prevent any malfunction, add an external circuit that prevents the
power supply to the controlled system from going ON before the power supply
to the PLC itself.
Managing CPU Unit
Errors
When any of the following errors occurs, PLC operation (program execution)
will stop and all outputs from Output Units will be turned OFF.
• A CPU error (watchdog timer error) or CPU on standby
• A fatal error (memory error, I/O bus error, duplicate number error, too
many I/O points error, I/O setting error, program error, cycle time too long
error, or FALS(007) error) (See note.)
Always add any circuits necessary outside of the PLC to ensure the safety of
the system in the event of an error that stops PLC operation.
Note
When a fatal error occurs, all outputs from Output Units will be turned OFF
even if the IOM Hold Bit has been turned ON to protect the contents of I/O
memory. (When the IOM Hold Bit is ON, the outputs will retain their previous
status after the PLC has been switched from RUN/MONITOR mode to PROGRAM mode.)
Managing Output
Malfunctions
It is possible for an output to remain ON due to a malfunction in the internal
circuitry of the Output Unit, such as a relay or transistor malfunction. Always
add any circuits necessary outside of the PLC to ensure the safety of the system in the event that an output fails to go OFF.
Interlock Circuits
When the PLC controls an operation such as the clockwise and counterclockwise operation of a motor and if there is any possibility of an accident or
mechanical damage due to faulty PLC operation, provide an external interlock
such as the one shown below to prevent both the forward and reverse outputs
from turning ON at the same time.
Example
Interlock circuit
CP1H
CIO
100.00
CIO
100.01
MC2
MC1 Motor clockwise
MC1
MC2 Motor counterclockwise
This circuit prevents outputs MC1 and MC2 from both being ON at the same
time even if both PLC outputs CIO 100.00 and CIO 100.01 are both ON, so
the motor is protected even if the PLC is programmed improperly or malfunctions.

Installation Precautions
Installation and Wiring Precautions
Always consider the following factors when installing and wiring the PLC to
improve the reliability of the system and make the most of the CP1L functions.
Ambient Conditions
Do not install the PLC in any of the following locations.
• Locations subject to ambient temperatures lower than 0°C or higher than
55°C.
• Locations subject to drastic temperature changes or condensation.
• Locations subject to ambient humidity lower than 10% or higher than
90%.
• Locations subject to corrosive or flammable gases.
• Locations subject to excessive dust, salt, or metal filings.
• Locations that would subject the PLC to direct shock or vibration.
• Locations exposed to direct sunlight.
• Locations that would subject the PLC to water, oil, or chemical reagents.
Always enclose or protect the PLC sufficiently in the following locations.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power lines.
Installation in
Cabinets or Control
Panels
When the CP1L is being installed in a cabinet or control panel, always provide
proper ambient conditions as well as access for operation and maintenance.
Temperature Control
The ambient temperature within the enclosure must be within the operating
range of 0°C to 55°C. When necessary, take the following steps to maintain
the proper temperature.
• Provide enough space for good air flow.
• Do not install the PLC above equipment that generates a large amount of
heat, such as heaters, transformers, or high-capacity resistors.
• If the ambient temperature exceeds 55°C, install a cooling fan or air conditioner.

Section 3-2
Installation Precautions
Accessibility for
Operation and
Maintenance
• To ensure safe access for operation and maintenance, separate the PLC
as much as possible from high-voltage equipment and moving machinery.
• The PLC will be easiest to install and operate if it is mounted at a height of
about 1,000 to 1,600 mm.
!Caution Do not touch the power supply or the area around the I/O terminals while
power is being supplied or immediately after power has been turned OFF.
Doing so may result in burns.
!Caution After the power supply has been turned OFF, wait until the PLC has sufficiently cooled before touching it.
Improving Noise
Resistance
• Do not mount the PLC in a control panel containing high-voltage equipment.
• Install the PLC at least 200 mm from power lines.

• Wire a separate circuit for the power supply circuit so that there is no voltage drop from the inrush current that flows when other equipment is
turned ON.
• When several CP1L PLCs are being used, it is recommended to wire the
PLCs on separate circuits to prevent a voltage drop from the inrush current or incorrect operation of the circuit breaker.
• Use twisted-pair power supply cables to prevent noise from the power
supply lines. Adding a 1:1 isolating transformer reduces electrical noise
even further.
• Consider the possibility of voltage drops and the allowable current, and
always use thick power lines.
• Use round crimp terminals for AC power supply wiring.
6.2 mm max.
• AC Power Supply
Provide a power supply of 100 to 240 VAC.
• Use a power supply within the following voltage fluctuation range.
Power supply voltage
100 to 240 VAC
Note
Allowable voltage fluctuation range
85 to 264 VAC
(1) Before connecting the power supply, make sure that the CPU Unit requires an AC power supply and not a DC power supply. The CPU Unit's
internal circuitry will be damaged if AC power is mistakenly supplied to a
CPU Unit that requires a DC power supply.
(2) The power supply input terminals are at the top of the CPU Unit; the terminals at the bottom of the CPU Unit output 24-VDC power for external
devices. The CPU Unit's internal circuitry will be damaged if AC power is
mistakenly supplied to a CPU Unit's power supply output terminals.
!Caution Tighten the terminal block screws for the AC power supply to the torque of
0.5 N·m. Loose screws may result in fire or malfunction.
• Always ground the ground terminal to 100 Ω or less to protect against
electric shock and incorrect operation from electrical noise.
111
Section 3-4
Wiring CP1L CPU Units
• If one phase of the power supply is grounded, connect the grounded
phase to the L2/N terminal.
• The GR terminal is a ground terminal. To prevent electrical shock, use a
dedicated ground line (2 mm2 min.) of 100 Ω or less.
• The line ground terminal (LG) is a noise-filtered neutral terminal. If noise
is a significant source of errors or if electrical shocks are a problem, connect the line ground terminal (LG) to the ground terminal (GR) and ground
both with a ground resistance of 100 Ω or less.
• To prevent electrical shock when short-circuiting between the LG and GR
terminals, always use a ground of 100 Ω or less.
• Do not connect ground lines to other devices or to the frame of a building.
Doing so will reverse the effectiveness of the ground and instead have a
bad influence.
Isolating Transformer
The PLC's internal noise control is sufficient for the general noise to which
power supply lines are subjected. Ground noise can be further reduced by
providing the power supply through a 1:1 isolating transformer. Leave the isolating transformer's secondary side ungrounded.

Wiring Built-in I/O
Wiring Precautions
Double-checking I/O
Specifications
Double-check the specifications for the I/O Units. In particular, do not apply a
voltage that exceeds the input voltage for Input Units or the maximum switching capacity for Output Units. Doing so may result in breakdown, damage, or
fire.
When the power supply has positive and negative terminals, always wire them
correctly.
• AWG22 to AWG18 (0.32 to 0.82 mm2) power lines are recommended.
Use cable with a maximum diameter of 1.61 mm including the insulation
covering.
Electric Wires
• The current capacity of electric wire depends on factors such as the ambient temperature and insulation thickness, as well as the gauge of the conductor.
• M3 self-rising screws are used for all screw terminals including terminal
screws for crimp terminal power supply wiring.
• Use crimp terminals or solid wire for wiring.
• Do not connect bare stranded wires directly to terminals.
• Tighten the terminal block screws to the torque of 0.5 N·m.
• Use crimp terminals (M3) having the dimensions shown below.
6.2 mm max.
Wiring
6.2 mm max.
• Wire the Units so that they can be easily replaced.
• Make sure that the I/O indicators are not covered by the wiring.
• Do not place the I/O wiring in the same conduits or ducts as high-voltage
or power lines. Inductive noise can cause errors or damage.
• Tighten the terminal screws to the torque of 0.5 N·m.
Note
(1) Never apply a voltage that exceeds the input voltage for Input Units or the
maximum switching capacity for Output Units.
(2) When the power supply has positive and negative terminals, always wire
them correctly.
(3) When required by EC Low Voltage Directive, use reinforced insulation or
double insulation on the DC power supply connected to DC-power-supply
CPU Units and I/O.
For the DC power supply connected to a DC-power-supply CPU Unit, use
a power supply with a minimum output holding time of 10 ms.
(4) Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables.

Precautions when
Connecting a Two-wire DC
Sensor
When using a two-wire sensor with a 24-V DC input device, check that the following conditions have been met. Failure to meet these conditions may result
in operating errors.
1,2,3...
1. Relation between voltage when the PLC is ON and the sensor residual
voltage:
VON ≤ VCC − VR
2. Relation between current when the PLC is ON and sensor control output
(load current):
IOUT (min) ≤ ION ≤ IOUT (max)
ION = (VCC − VR − 1.5 [PLC internal residual voltage]*)/RIN
When ION is smaller than IOUT (min), connect a bleeder resistor R. The
bleeder resistor constant can be calculated as follows:
R ≤ (VCC − VR)/(IOUT (min) − ION)
Power W ≥ (VCC − VR)2/R × 4 [allowable margin]
114
Section 3-4
Wiring CP1L CPU Units
3. Relation between current when the PLC is OFF and sensor leakage current:
IOFF ≥ Ileak
Connect a bleeder resistor if Ileak is greater than IOFF. Use the following
equation to calculate the bleeder resistance constant.
R ≤ RIN × VOFF/(Ileak × RIN − VOFF)
Power W ≥ (VCC − VR)2/R × 4 (allowable margin)

R: Bleeder resistance
Rin: PLC input impedance
4. Precautions on Sensor Inrush Current
An incorrect input may occur due to sensor inrush current if a sensor is
turned ON after the PLC has started up to the point where inputs are possible. Determine the time required for sensor operation to stabilize after the
sensor is turned ON and take appropriate measures, such as inserting into
the program a timer delay after turning ON the sensor.
Program Example
In this example, the sensor's power supply voltage is provided to input bit CIO
0.00 and a 100-ms timer delay (the time required for an OMRON Proximity
Sensor to stabilize) is created in the program. After the Completion Flag for
the timer turns ON, the sensor input on input bit CIO 0.01 will cause output bit
CIO 100.00 to turn ON.

Output Wiring Precautions
Output Short-circuit
Protection
If a load connected to the output terminals is short-circuited, output components and the printed circuit boards may be damaged. To guard against this,
incorporate a fuse in the external circuit. Use a fuse with a capacity of about
twice the rated output.
Connecting to a TTL
Circuit
A TTL circuit cannot be connected directly to a transistor output because of
the transistor's residual voltage. It is necessary to connect a pull-up resistor
and a CMOS IC between the two.
Inrush Current
Considerations
When connecting a transistor or triac output to a load having a high inrush
current (such as an incandescent lamp), steps must be taken to avoid damage to the transistor or triac. Use either of the following methods to reduce the
inrush current.

Pulse Output Connection Examples
This example shows a connection to a motor driver. Always check the specifications of the motor driver before actually connecting it.
For open-collector output, use a maximum of 3 m of wiring between the CP1L
CPU Unit and the motor driver.
No pulses are output while the pulse output transistor is OFF. For a direction
output, OFF indicates that CCW output is in progress.
Do not use the same power supply for both pulse output 24-VDC/5-VDC
power and other I/O power.

In this example, a 5-V input motor driver is used with a 24-VDC power supply.
Be careful to ensure that the Position Control Unit output current does not
damage the input circuit at the motor driver and yet is sufficient to turn it ON.
Take into account the power derating for the 1.6-kΩ resistance.

Overview of the Data Areas
■ CIO Area
It is not necessary to input the “CIO” acronym when specifying an address in
the CIO Area. The CIO Area is generally used for data exchanges, such as
I/O refreshing with PLC Units. Words that are not allocated to Units may be
used as work words and work bits in the program.

Note
The parts of the CIO Area that are labelled “not used” may be used in programming as work bits. In the future, however, unused CIO Area bits may be
used when expanding functions. Always use Work Area bits first.
I/O Area (Inputs: CIO 0 to CIO 99, Outputs: CIO 100 to CIO 199)
These words are allocated to built-in I/O terminals of CP1L CPU Units and
CP-series Expansion Units or Expansion I/O Units. Input words and output
bits that aren’t allocated may be used in programming.
139
Section 4-1
Overview of I/O Memory Area
1:1 Link Area
These bits are used by the 1:1 Link Master and Slave. They are used for data
links between CP1L CPU Units and [email protected] CPU Units.
Serial PLC Link Area
These words are allocated for use for data links (Serial PLC Links) with other
CP1L CPU Units or CP1H CPU Units. Addresses not used for Serial PLC
Links can be used in programming.
Internal I/O Area
These words can be used in programming; they cannot be used for I/O
exchange with external I/O terminals. Be sure to use the work words provided
in the Work Area before using words in the Internal I/O Area or other unused
words in the CIO Area. It is possible that these words will be assigned to new
functions in future versions of the CPU Units. The parts of the CIO Area that
are labelled “Not used” are functionally identical to the Internal I/O Area.
Work Area (W)
Words in the Work Area can be used in programming; they cannot be used for
I/O exchange with external I/O terminals. Use this area for work words and
bits before any words in the CIO Area.
Word 15

Note
Holding Area (H)
These words should be used first in programming be assigned to new functions in future versions of CP1L CPU Units.
Words in the Holding Area can be used in programming. These words retain
their content when the PLC is turned ON or the operating mode is switched
between PROGRAM mode and RUN or MONITOR mode.
Word 15

H511
Note H512 to H1535 are used as a Function Block Holding Area. These words can
be used only for function block instances (internally allocated variable area).
These words cannot be specified as instruction operands in the user program.

Data Memory Area (D)
The DM Area is a multi-purpose data area that is normally accessed only in
word-units. These words retain their content when the PLC is turned ON or
the operating mode is switched between PROGRAM mode and RUN or MONITOR mode.

Timer Area (T)
D32767
There are two parts to the Timer Area: the Timer Completion Flags and the
timer Present Values (PVs). Up to 4,096 timers with timer numbers T0 to
T4095 can be used.
Timer Completion Flags
These flags are read as individual bits. A Completion Flag is turned ON by the
system when the corresponding timer times out (i.e., when the set time
elapses).
Timer PVs
The PVs are read and written as words (16 bits). The PVs count up or down
as the timer operates.
Counter Area (C)
There are two parts to the Counter Area: the Counter Completion Flags and
the Counter Present Values (PVs). Up to 4,096 counters with counter numbers C0 to C4095 can be used.
Counter Completion Flags
These flags are read as individual bits. A Completion Flag is turned ON by the
system when the corresponding counter counts out (i.e., when the set value is
reached).
141
Overview of I/O Memory Area
Section 4-1
Counter PVs
The PVs are read and written as words (16 bits). The PVs count up or down
as the counter operates.
Condition Flags
These flags include the Arithmetic Flags, such as the Error Flag and Equals
Flag, which indicate the results of instruction execution as well as the Always
ON and Always OFF Flags. The Condition Flags are specified with symbols
rather than addresses.
Clock Pulses
The Clock Pulses are turned ON and OFF by the CPU Unit’s internal timer.
These bits are specified with symbols rather than addresses.
Task Flag Area (TK)
A Task Flag will be ON when the corresponding cyclic task is in executable
(RUN) status and OFF when the cyclic task hasn’t been executed (INI) or is in
standby (WAIT) status.
Index Registers (IR)
Index registers (IR0 to IR15) are used to store PLC memory addresses (i.e.,
absolute memory addresses in RAM) to indirectly address words in I/O memory. The Index Registers can be used separately in each task or they can be
shared by all tasks.
Data Registers (DR)
Data registers (DR0 to DR15) are used together with Index Registers. When a
Data Register is input just before an Index Register, the content of the Data
Register is added to the PLC memory address in the Index Register to offset
that address. The Data Registers can be used separately in each task or they
can be shared by all tasks.

Input Bits: CIO 0.00 to CIO 99.15 (100 words)
Output Bits: CIO 100.00 to CIO 199.15 (100 words)
The starting words for inputs and outputs are predetermined for CP1L CPU
Unit. Input bits in CIO 0 and CIO 1 and output bits in CIO 100 and CIO 101
are automatically allocated to the built-in I/O on the CPU Unit. CP-series
Expansion Units and CP-series Expansion I/O Units are automatically allocated input bits in words starting from CIO 2 and output bits in words starting
from CIO 102.

For example, with a CPU Unit with 40 I/O points, the input bits in CIO 0 and
CIO 1 and the outputs bits in CIO 100 and CIO 101 would be allocated to the
built-in I/O of the CPU Unit. Input bits in CIO 2 and higher and outputs bits in
CIO 102 and higher would be automatically allocated in order to any Expansion Units or Expansion I/O Units connected to the CPU Unit.
When the power to the CPU Unit is turned ON, the CPU Unit checks for any
Expansion Units and Expansion I/O Units connected to it and automatically
allocates I/O bits. If the order in which the Units are connected is changed, the
the bits used in the ladder program will no longer match the bits allocated to
the actual Units. Always review the ladder program whenever changing the
order in which Units are connected.

24 output bits
For a CPU Unit with 40 I/O points (shown above), a total of 24 input bits are
allocated to the input terminal block. The bits that are allocated are input bits
CIO 0.00 to CIO 0.11 (i.e., bits 00 to 11 in CIO 0) and input bits CIO 1.00 to
CIO 1.11 (i.e., bits 00 to 11 in CIO 1).
In addition, a total of 16 output bits are allocated to the output terminal block.
The bits that are allocated are output bits CIO 100.00 to CIO 100.07 (i.e., bits

The upper bits (bits 12 to 15) not used in the input words cannot be used as
work bits. Only the bits not used in the output words can be used as work bits.

I/O Bits Allocated to Expansion I/O Units
There are Expansion I/O Units for expanding inputs, for expanding outputs,
and for expanding both input and outputs. I/O bits starting from bit 00 in the
next word after the word allocated to the previous Expansion Unit, Expansion
I/O Unit, or CPU Unit are automatically allocated. This word is indicated as
“CIO m” for input words and as “CIO n” for output words.

The 1:1 Link Area contains 1,024 bits (64 words) with addresses ranging from
CIO 3000.00 to CIO 3063.15 (CIO 3000 to CIO 3063).
These bits are used to create 1:1 links (i.e., shared data link areas) by connecting the RS-232C ports of two PLCs, including the CP1L, CPM1A,
CPM2A, CPM2B, CPM2C, SRM1(-V2), CQM1H, and C200HX/HG/HE(-Z).

Serial PLC Link Area
The Serial PLC Link Area contains 1,440 bits (90 words) with addresses ranging from CIO 3100.00 to CIO 3189.15 (CIO 3100 to CIO 3189).
Words in the Serial PLC Link Area can be used for data links with other PLCs.
Serial PLC Links exchange data among CPU Units via the built-in RS-232C
ports, with no need for special programming.
The Serial PLC Link allocations are set automatically by means of the following PLC Setup in the Polling Unit.
• Serial PLC Link Mode
• Number of Serial PLC Link transfer words
• Maximum Serial PLC Link unit number

Serial PLC Link Area
Initialization
The contents of the Serial PLC Link Area will be cleared in the following
cases:
1. When the operating mode is changed from PROGRAM mode to
RUN/MONITOR mode or vice-versa and the IOM Hold Bit is OFF
2. When the power is cycled
3. When the Serial PLC Link Area is cleared from the CX-Programmer
4. When PLC operation is stopped when a fatal error other than an
FALS(007) error occurs (The contents of the Serial PLC Link Area will be
retained when FALS(007) is executed.)
4-5
Internal Work Area
The Internal Work Area contains 512 words with addresses ranging from W0
to W511. These words can be used in programming as work words.
There are unused words in the CIO Area (CIO 3800 to CIO 6143) that can
also be used in the program, but use any available words in the Work Area
first because the unused words in the CIO Area may be allocated to other
applications when functions are expanded.
Forcing Bit Status
Bits in the Work Area can be force-set and force-reset.
Work Area Initialization
The contents of the Work Area will be cleared in the following cases:
1. When the operating mode is changed from PROGRAM to RUN or MONITOR mode or vice-versa and the IOM Hold Bit is OFF
2. When the power is cycled
3. When the Work Area is cleared from the CX-Programmer.
153
Section 4-6
Holding Area (H)
4. When PLC operation is stopped when a fatal error other than an
FALS(007) error occurs. (The contents of the Work Area will be retained
when FALS(007) is executed.)
4-6
Holding Area (H)
The Holding Area contains 512 words with addresses ranging from H0 to
H511 (bits H0.00 to H511.15). These words can be used in programming.
Holding Area Initialization
Data in the Holding Area is not cleared when the power is cycled or the PLC’s
operating mode is changed from PROGRAM mode to RUN or MONITOR
mode or vice-versa.
A Holding Area bit will be cleared if it is programmed between IL(002) and
ILC(003) and the execution condition for IL(002) is OFF. To keep a bit ON
even when the execution condition for IL(002) is OFF, turn ON the bit with the
SET instruction just before IL(002).
Self-maintaining Bits
When a self-maintaining bit is programmed with a Holding Area bit, the selfmaintaining bit won’t be cleared even when the power is reset.
Note
1. If a Holding Area bit is not used for the self-maintaining bit, the bit will be
turned OFF and the self-maintaining bit will be cleared when the power is
reset.
2. If a Holding Area bit is used but not programmed as a self-maintaining bit
as in the following diagram, the bit will be turned OFF by execution condition A when the power is reset.
H0.00

3. H512 to H1535 are used as a Function Block Holding Area. These words
can be used only for function block instances (internally allocated variable
area). These words cannot be specified as instruction operands in the user
program.
Precautions
When a Holding Area bit is used in a KEEP(011) instruction, never use a normally closed condition for the reset input if the input device uses an AC power
supply. When the power supply goes OFF or is temporarily interrupted, the
input will go OFF before the PLC’s internal power supply and the Holding Area
bit will be reset.

Auxiliary Area (A)
The Auxiliary Area contains 960 words with addresses ranging from A0 to
A959). These words are preassigned as flags and control bits to monitor and
control operation.
A0 through A447 are read-only, but A448 through A959 can be read or written
from the program or the CX-Programmer.
Refer to Appendix C Auxiliary Area Allocations by Function and Appendix D
Auxiliary Area Allocations by Address for Auxiliary Area functions.
Forcing Bit Status
4-8
Read/write bits in the Auxiliary Area cannot be force-set and force-reset continuously.
TR (Temporary Relay) Area
The TR Area contains 16 bits with addresses ranging from TR0 to TR15.
These temporarily store the ON/OFF status of an instruction block for branching and are used only with mnemonics. TR bits are useful when there are several output branches and interlocks cannot be used.
The TR bits can be used as many times as required and in any order required
as long as the same TR bit is not used twice in the same instruction block.
TR bits can be used only with the OUT and LD instructions. OUT instructions
(OUT TR0 to OUT TR15) store the ON OFF status of a branch point and LD
instructions recall the stored ON OFF status of the branch point.
Forcing Bit Status
TR bits cannot be changed from the CX-Programmer.
Examples
In this example, a TR bit is used when two outputs have been directly connected to a branch point.

Timers and Counters
Timer Area (T)
The 4,096 timer numbers (T0000 to T4095) are shared by the TIM,
TIMX(550), TIMH(015), TIMHX(551), TMHH(540), TIMHHX(552), TTIM(087),
TTIMX(555), TIMW(813), TIMWX(816), TMHW(815), and TIMHWX(817)
instructions. Timer Completion Flags and present values (PVs) for these
instructions are accessed with the timer numbers.
The TIML(542), TIMLX(553), MTIM(543), and MTIMX(554) instructions do not
use timer numbers.
When a timer number is used in an operand that requires bit data, the timer
number accesses the Completion Flag of the timer. When a timer number is
used in an operand that requires word data, the timer number accesses the
PV of the timer. Timer Completion Flags can be used as often as necessary
as normally open and normally closed conditions and the values of timer PVs
can be read as normal word data.
The refresh method for timer PVs can be set from the CX-Programmer to
either BCD or binary.
Note It is not recommended to use the same timer number in two timer instructions
because the timers will not operate correctly if they are timing simultaneously.
(If two or more timer instructions use the same timer number, an error will be
generated during the program check, but the timers will operate as long as the
instructions are not executed in the same cycle.)

cleared when power is cycled.
2. If the IOM Hold Bit (A50012) is ON and the PLC Setup’s IOM Hold Bit Status at Startup setting is set to protect the IOM Hold Bit, the PV and Completion Flag will be retained when the PLC’s power is cycled.
3. Since the TIML(542), TIMLX(553), MTIM(543), and MTIMX(554) instructions do not use timer numbers, they are reset under different conditions.
Refer to the descriptions of these instructions for details.
4. The present value of TIM, TIMX(550), TIMH(015), TIMHX(551), TMHH(540), TMHHX(552), TIMW(813), TIMWX(816), TMHW(815) and TMHWX(817) timers programmed with timer numbers 0000 to 2047 will be
updated even when jumped between JMP and JME instructions or when
in a task that is on standby. The present value of timers programmed with
timer numbers 2048 to 4095 will be held when jumped or when in a task
that is on standby.
Forcing Bit Status
Timer Completion Flags can be force-set and force-reset.
Timer PVs cannot be force-set or force-reset, although the PVs can be
refreshed indirectly by force-setting/resetting the Completion Flag.
Restrictions
4-9-2
There are no restrictions in the order of using timer numbers or in the number
of N.C. or N.O. conditions that can be programmed. Timer PVs can be read as
word data and used in programming.
Counter Area (C)
The 4,096 counter numbers (C0000 to C4095) are shared by the CNT,
CNTX(546), CNTR(012), CNTRX(548), CNTW(814), and CNTWX(818)
instructions. Counter Completion Flags and present values (PVs) for these
instructions are accessed with the counter numbers.
When a counter number is used in an operand that requires bit data, the
counter number accesses the Completion Flag of the counter. When a
counter number is used in an operand that requires word data, the counter
number accesses the PV of the counter.
157
Section 4-9
Timers and Counters
The refresh method for counter PVs can be set from the CX-Programmer to
either BCD or binary. (Refer to the previous page).
It is not recommended to use the same counter number in two counter
instructions because the counters will not operate correctly if they are counting simultaneously. If two or more counter instructions use the same counter
number, an error will be generated during the program check, but the counters
will operate as long as the instructions are not executed in the same cycle.

This data area is used for general data storage and manipulation and is
accessible only by word.
Data in the DM Area is retained when the PLC’s power is cycled or the PLC’s
operating mode is changed from PROGRAM mode to RUN/MONITOR mode
or vice-versa.
Although bits in the DM Area cannot be accessed directly, the status of these
bits can be accessed with the BIT TEST instructions, TST(350) and
TSTN(351).
Forcing Bit Status
Bits in the DM Area cannot be force-set or force-reset.
Indirect Addressing
Words in the DM Area can be indirectly addressed in two ways: binary-mode
and BCD-mode.
Binary-mode Addressing (@D)
When a “@” character is input before a DM address, the content of that DM
word is treated as binary and the instruction will operate on the DM word at
that binary address. The entire DM Area (D0 to D32767) can be indirectly
addressed with hexadecimal values 0000 to 7FFF.

BCD-mode Addressing (*D)
When a “*” character is input before a DM address, the content of that DM
word is treated as BCD and the instruction will operate on the DM word at that
BCD address. Only part of the DM Area (D0 to D09999) can be indirectly
addressed with BCD values 0000 to 9999.

Section 4-11
Index Registers
(2) If two-word data is accessed from the last address in the DM Area (D9999
for the [email protected]@[email protected] and D32767 for other CPU Units), the Access Error Flag (P_AER) will turn ON and the data at D9999 or D32767 will not

For use of these areas, refer to 6-3-3 Modbus-RTU Easy Master Function.
4-11 Index Registers
The sixteen Index Registers (IR0 to IR15) are used for indirect addressing.
Each Index Register can hold a single PLC memory address, which is the
absolute memory address of a word in I/O memory. Use MOVR(560) to convert a regular data area address to its equivalent PLC memory address and
write that value to the specified Index Register. (Use MOVRW(561) to set the
PLC memory address of a timer/counter PV in an Index Register.)
Note Refer to Appendix E Memory Map for more details on PLC memory
addresses.
Indirect Addressing
When an Index Register is used as an operand with a “,” prefix, the instruction
will operate on the word indicated by the PLC memory address in the Index
Register, not the Index Register itself. Basically, the Index Registers are I/O
memory pointers.
• All addresses in I/O memory (except Index Registers, Data Registers, and
Condition Flags) can be specified seamlessly with PLC memory
addresses. It isn’t necessary to specify the data area. I/O memory
addresses for IR, DR, and Condition Flags, however, cannot be held.
• In addition to basic indirect addressing, the PLC memory address in an
Index Register can be offset with a constant or Data Register, auto-incremented, or auto-decremented. These functions can be used in loops to
read or write data while incrementing or decrementing the address by one
each time that the instruction is executed.
With the offset and increment/decrement variations, the Index Registers can
be set to base values with MOVR(560) or MOVRW(561) and then modified as
pointers in each instruction.
I/O Memory
Set to a base value
with MOVR(560) or
MOVRW(561).
Pointer
Note It is possible to specify regions outside of I/O memory and generate an Illegal
Access Error when indirectly addressing memory with Index Registers. Refer
to Appendix E Memory Map for details on the limits of PLC memory
addresses.

The content of the Data Register
is added to the content of [email protected] and
the result is treated as the PLC

Syntax
After referencing the content of
[email protected] as the PLC memory address
of a bit or word, the content is
incremented by 1 or 2.
Indirect addressing
The content of [email protected] is decrewith auto-decrement mented by 1 or 2 and the result is
treated as the PLC memory
address of a bit or word.

Section 4-11
Index Registers
Since some operands are treated as word data and others are treated as bit
data, the meaning of the data in an Index Register will differ depending on the
operand in which it is used.
1,2,3...
1. Word Operand:
MOVR(560)
0000
MOV(021)
D0
IR2
, IR2
When the operand is treated as a word, the contents of the Index Register
are used “as is” as the PLC memory address of a word.
In this example MOVR(560) sets the PLC memory address of CIO 2 in IR2
and the MOV(021) instruction copies the contents of D0 to CIO 2.
2. Bit Operand:
MOVR(560)
SET
000013
+5 , IR2
,IR2
When the operand is treated as a bit, the leftmost 7 digits of the Index Register specify the word address and the rightmost digit specifies the bit number. In this example, MOVR(560) sets the PLC memory address of CIO 13
(0C00D hex) in IR2. The SET instruction adds +5 from bit 13 (D hex) to this
PLC memory address, so it turns ON bit CIO 1.02.
Index Register
Initialization
The Index Registers will be cleared in the following cases:
1. When the operating mode is changed from PROGRAM to RUN or MONITOR mode or vice-versa
2. When the power is cycled
Setting Index Registers
Always set the required value in an index register before using it. The contents
of an index register will be unpredictable if it is not set in advance.
The contents of an index register is also unpredictable after an interrupt task
is started. When using index registers inside an interrupt task, use
MOVR(560) (for anything but timer/counter PVs) or MOVRW(561) (for
timer/counter PVs) to set the required value.
Direct Addressing
When an Index Register is used as an operand without a “,” prefix, the instruction will operate on the contents of the Index Register itself (a two-word or
“double” value). Index Registers can be directly addressed only in the instructions shown in the following table. Use these instructions to operate on the
Index Registers as pointers.
The Index Registers cannot be directly addressed in any other instructions,
although they can usually be used for indirect addressing.

The SRCH(181), MAX(182), and MIN(183) instructions can output the PLC
memory address of the word with the desired value (search value, maximum,
or minimum) to IR0. In this case, IR0 can be used in later instructions to
access the contents of that word.
4-11-1 Using Index Registers
Processing of multiple (identical) instructions such as consecutive addresses
for table data can be merged into one instruction by combining repetitive processing (e.g., FOR(513) and NEXT(514)instructions) with indirect addressing
using Index Registers, thereby simplifying programming.

The Index operation uses the following procedure.
1. PLC memory addresses for the addresses in the Index Registers are
stored using a MOVR instruction.
2. Operation is then executed by indirectly addressing Index Registers to the
operand for Instruction A.
3. The addresses are moved using processing such as adding, subtracting,
incrementing, or decrementing the Index Register (see note).
4. Steps 2 and 3 are processed repeatedly until the conditions are met.
Note
Adding, subtracting incrementing, or decrementing for the Index
Register is performed using one of the following methods.
• Each Type of Indirect Addressing for Index Registers:
Auto-increment (,[email protected]+ or ,IR@++), auto-decrement (,[email protected] or ,[email protected]),
constant offset (constant ,[email protected]), and DR offset ([email protected],[email protected]) for Index
Registers
• Instructions for Direct Addressing of Index Registers:
DOUBLE SIGNED BINARY ADD WITHOUT CARRY (+L), DOUBLE
SIGNED BINARY SUBTRACT WITHOUT CARRY (-L), DOUBLE INCREMENT BINARY (++L), DOUBLE DECREMENT BINARY (--L)

MOVR m IR0
The PLC memory address
of address m is stored in IR0.
Instruction A m+1
Instruction A ,IR0+
Repeated execution,
e.g., loop for
FOR or NEXT.
Instruction A m+n
If, for example, instruction A above is a comparison instruction, table data
could be read from start to the end of the table to compare all of the data with
a specific value. In this way, blocks of user-defined processing can be freely
created depending by applying Index Registers.
■ Example Using Index Registers
In the following example, TIM instructions for timer numbers 0 to 99 use set
values in D100 to D199. This can be achieved by using one TIM instruction,
using an index register for the timer number, using another index register for
the Completion Flags, and repeatedly executing the TIM instruction to start
the timers.
The PLC memory addresses for each T0's PV, Completion
Flag, and W0.00 are set in Index Registers IR0, IR1, and IR2 using a
MOVRW or MOVR instruction.
- The TIM instruction is executed for the timer number
(timer PV) that IR0+ indirectly addresses.
- The Timer Completion Flag that is indirectly addressed for
IR1+ turns ON when the time elapses. When the ON status
is received, bits in the work area that are indirectly
addressed for IR2+ are turned ON.
- The contents of IR0+, IR1+, and IR2+ are automatically
incremented by one after accessing the values using indirect
addressing.
- D0 is incremented.

4-11-2 Precautions for Using Index Registers
Precautions
Do not use a Index Register until a PLC memory address has been set in the
register. The pointer operation will be unreliable if the registers are used without setting their values.
The values in Index Registers are unpredictable at the start of an interrupt
task. When an Index Register will be used in an interrupt task, always set a
PLC memory address in the Index Register with MOVR(560) or MOVRW(561)
before using the register in that task.
Each Index Register task is processed independently, so they do not affect
each other. For example, IR0 used in Task 1 and IR0 used in Task 2 are different. Consequently, each Index Register task has 16 Index Registers.
166
Section 4-11
Index Registers
Limitations when Using Index Registers
• It is only possible to read the Index Register for the last task executed
within the cycle from the CX-Programmer. If using Index Registers with
the same number to perform multiple tasks, it is only possible with the CXProgrammer to read the Index Register value for the last task performed
within the cycle from the multiple tasks, nor is it possible to write the Index
Register value from the CX-Programmer.
• It is not possible to either read or write to the Index Registers using Host
Link commands or FINS commands.
• A setting can be made from the CX-Programmer to share Index Registers
between tasks. This setting will be enabled uniformly for all Index Registers and Data Registers.
Sharing Index Registers
The following setting can be made from the PLC Properties Dialog Box on the
CX-Programmer to control sharing Index and Data Registers between tasks.
Monitoring Index Registers
It is possible to monitor Index Registers as follows:
To use the Programming Devices to monitor the final Index Register values for
each task, or to monitor the Index Register values using Host Link commands
or FINS commands, write a program to store Index Register values from each
task to another area (e.g., DM area) at the end of each task, and to read Index
Register values from the storage words (e.g., DM area) at the beginning of
each task. The values stored for each task in other areas (e.g., DM area) can
then be edited using the CX-Programmer, Host Link commands, or FINS
commands.

4-12 Data Registers
The sixteen Data Registers (DR0 to DR15) are used to offset the PLC memory addresses in Index Registers when addressing words indirectly.
The value in a Data Register can be added to the PLC memory address in an
Index Register to specify the absolute memory address of a bit or word in I/O
memory. Data Registers contain signed binary data, so the content of an
Index Register can be offset to a lower or higher address.
168
Section 4-12
Data Registers
Normal instructions can be used to store data in Data Registers.
Forcing Bit Status
Bits in Data Registers cannot be force-set and force-reset.
Set to a base value
with MOVR(560) or
MOVRW(561).
I/O Memory
Pointer
Set with a regular
instruction.
Examples
The following examples show how Data Registers are used to offset the PLC

0 to 32,767
The Data Registers will be cleared in the following cases:
1. When the operating mode is changed from PROGRAM mode to
RUN/MONITOR mode or vice-versa and the IOM Hold Bit is OFF
2. When the power is cycled and the IOM Hold Bit is OFF or not protected in
the PLC Setup
IOM Hold Bit Operation
If the IOM Hold Bit (A500.12) is ON, the Data Registers won’t be cleared
when a FALS error occurs or the operating mode is changed from PROGRAM
mode to RUN/MONITOR mode or vice-versa.
If the IOM Hold BIt (A500.12) is ON and the PLC Setup’s “IOM Hold Bit Status
at Startup” setting is set to protect the IOM Hold Bit, the Data Registers won’t
be cleared when the PLC’s power supply is reset (ON →OFF →ON).
Precautions
Data Registers are normally local to each task. For example, DR0 used in
task 1 is different from DR0 used in task 2. (A PLC Setup setting can be made
from the CX-Programmer to share Data Registers between tasks.)
The content of Data Registers cannot be accessed (read or written) from the
CX-Programmer.
Do not use Data Registers until a value has been set in the register. The register’s operation will be unreliable if they are used without setting their values.
The values in Data Registers are unpredictable at the start of an interrupt
task. When a Data Register will be used in an interrupt task, always set a
value in the Data Register before using the register in that task.

Section 4-13
Task Flags
4-13 Task Flags
Task Flags range from TK00 to TK31 and correspond to cyclic tasks 0 to 31. A
Task Flag will be ON when the corresponding cyclic task is in executable
(RUN) status and OFF when the cyclic task hasn’t been executed (INI) or is in
standby (WAIT) status.
Note These flags indicate the status of cyclic tasks only, they do not reflect the status of interrupt tasks.
Task Flag Initialization
The Task Flags will be cleared in the following cases, regardless of the status
of the IOM Hold Bit.
1. When the operating mode is changed from PROGRAM mode to
RUN/MONITOR mode or vice-versa
2. When the power is cycled.
Forcing Bit Status
The Task Flags cannot be force-set and force-reset.
4-14 Condition Flags
These flags include the Arithmetic Flags, such as the Error Flag and Equals
Flag, which indicate the results of instruction execution.
The Condition Flags are specified with symbols, such as P_CY and P_ER,
rather than addresses. The status of these flags reflects the results of instruction execution, but the flags are read-only; they cannot be written directly from
instructions or the CX-Programmer.
Note The CX-Programmer treats condition flags as global symbols beginning with
P_.
All Condition Flags are cleared when the program switches tasks, so the status of the ER and AER flags are maintained only in the task in which the error
occurred.
Forcing Bit Status
The Condition Flags cannot be force-set and force-reset.
Summary of the Condition
Flags
The following table summarizes the functions of the Condition Flags, although
the functions of these flags will vary slightly from instruction to instruction.
Refer to the description of the instruction for complete details on the operation
of the Condition Flags for a particular instruction.

Function
Turned ON when the operand data in an instruction is incorrect (an
instruction processing error) to indicate that an instruction ended
because of an error.
When the PLC Setup is set to stop operation for an instruction error
(Instruction Error Operation), program execution will be stopped and
the Instruction Processing Error Flag (A29508) will be turned ON
when the Error Flag is turned ON.
Turned ON when an Illegal Access Error occurs. The Illegal Access
Error indicates that an instruction attempted to access an area of
memory that should not be accessed.
When the PLC Setup is set to stop operation for an instruction error
(Instruction Error Operation), program execution will be stopped and
the Instruction Processing Error Flag (A429510) will be turned ON
when the Access Error Flag is turned ON.

the result word(s).
Turned ON when the first operand of a Comparison Instruction is
greater than or equal to the second.
Turned ON when the two operands of a Comparison Instruction are

The Condition Flags are shared by all of the instructions, so their status may
change often in a single cycle. Be sure to read the Condition Flags immediately after the execution of instruction, preferably in a branch from the same
execution condition.

Since the Condition Flags are shared by all of the instructions, program operation can be changed from its expected course by interruption of a single task.
Be sure to consider the effects of interrupts when writing the program. Refer
to SECTION 2 Programming of CS/CJ Series Programming Manual (W394)
for more details.
The Condition Flags are cleared when the program switches tasks, so the status of a Condition Flag cannot be passed to another task. For example the
status of a flag in task 1 cannot be read in task 2.

Section 4-15
Clock Pulses
Saving and Loading Condition Flag Status
The CP1-H CPU Units support instructions to save and load the Condition
Flag status (CCS(282) and CCL(283)). These can be used to access the status of the Condition Flags at other locations in a task or in a different task.
The following example shows how the Equals Flag is used at a different location in the same task.

Stores result of comparison in the Condition Flags.
This will enable loading the results to use with
Instruction B.

High-speed Counters
Overview
• A rotary encoder can be connected to a built-in input to produce a highspeed pulse input.
• The PRV(881) instruction can be used to measure the input pulse frequency (one input only).
• The high-speed counter PVs can be maintained or refreshed.
• The High-speed Counter Gate Bit can be turned ON/OFF from the ladder
program to select whether the high-speed counter PVs will be maintained
or refreshed.
• Any one of the following input signals can be selected as the counter input
mode.
Response Frequencies for 24 VDC Inputs to High-speed Counters 0 and 1:
• Differential phase inputs (4x): 50 kHz
• Pulse + direction inputs: 100 kHz
• Up/Down pulse inputs: 100 kHz
• Increment pulse inputs: 100 kHz
Response Frequencies of CP1L-J show below:
• Differential phase inputs (4x): 10 kHz
• Pulse + direction inputs: 20 kHz
• Up/Down pulse inputs: 20 kHz
• Increment pulse inputs: 20 kHz
• The counting mode can be set to linear mode or circular (ring) mode.
• The counter reset method can be set to Z phase signal + software reset,
software reset, Z phase signal + software reset (continue comparing), or
software reset (continue comparing).
Pulse Input Functions

Description
Built-in input terminals can be used for high-speed counter
inputs.
The PV for the high-speed counters are stored in the Auxiliary
Area.
The counters can be operated in ring mode or linear mode.
The high-speed counter can be started or stopped (PV held)
from the Unit's program by turning ON/OFF the High-speed
Counter Gate Bit when the desired condition is met.
The PRV(881) instruction can be used to measure the pulse frequency.
• Range with differential phase inputs: 0 to 50 kHz (Y models: 0
to 500 kHz, J models : 0 to 10kHz)
• Range with all other input modes: 0 to 100 kHz (Y models: 0 to
1 MHz, J models : 0 to 20kHz))
PRV2(883) reads the pulse frequency and converts it to a rotational speed (r/min) or it converts the counter PV to a total number of rotations. Results are calculated by the number of pulses/
rotation.

• Only up-differentiated pulses (rising edges) can be counted.
Note The count of the high-speed counter can be monitored to see if it is currently
being incremented or decremented. The count in the current cycle is compared with the count in the previous cycle to determine if it is being incremented or decremented. The results are reflected in the High-speed Counter
Count Direction Flags (A274.10 for high-speed counter 0, A275.10 for highspeed Counter 1, A320.10 for high-speed counter 2, and A321.10 for highspeed counter 3.)
Counting Modes
Linear Mode
Input pulses can be counted in the range between the lower limit and upper
limit values. If the pulse count goes beyond the lower/upper limit, an underflow/overflow will occur and counting will stop.
Lower and Upper Limits of the Range
The following diagrams show the lower limit and upper limit values for increment mode and up/down mode.

Input pulses are counted in a loop within the set range. The loop operates as
follows:
• If the count is incremented from the max. ring count, the count will be
reset to 0 automatically and incrementing will continue.
• If the count is decremented from 0, the count will be set to the max. ring
count automatically and decrementing will continue.
Consequently, underflows and overflows cannot occur when ring mode is
used.

Max. Ring Count
Use the PLC Setup to set the max. ring count (Circular Max. Count), which is
the max. value of the input pulse counting range. The max. ring count can be
set to any value between 00000001 and FFFFFFFF hex.
180
Section 5-1
High-speed Counters
Restrictions
• There are no negative values in ring mode.
• If the max. ring count is set to 0 in the PLC Setup, the counter will operate
with a max. ring count of FFFFFFFF hex.
Reset Methods
Phase-Z Signal + Software
Reset
The high-speed counter's PV is reset when the phase-Z signal (reset input)
goes from OFF to ON while the corresponding High-speed Counter Reset Bit
is ON.
The CPU Unit recognizes the ON status of the High-speed Counter Reset Bit
only at the beginning of the PLC cycle during the overseeing processes. Consequently, when the Reset Bit is turned ON in the ladder program, the phaseZ signal does not become effective until the next PLC cycle.

The high-speed counter's PV is reset when the corresponding High-speed
Counter Reset Bit goes from OFF to ON.
The CPU Unit recognizes the OFF-to-ON transition of the High-speed
Counter Reset Bit only at the beginning of the PLC cycle during the overseeing processes. Reset processing is performed at the same time. The OFF-toON transition will not be recognized if the Reset Bit goes OFF again within the
same cycle.

Note The comparison operation can be set to stop or continue when a high-speed
counter is reset. This enables applications where the comparison operation
can be restarted from a counter PV of 0 when the counter is reset.

Inspecting a Dimension by
Counting Pulse Inputs
• This example is for a CPU Unit with 40 I/O Points.
• High-speed counter 0 is used.
• When the edge of the workpiece is detected, the counter PV is reset by a
phase-Z pulse.
• The workpiece is passes inspection if the final count is between 30,000
and 30,300, otherwise the workpiece fails.
• If the workpiece passes, output CIO 100.00 is turned ON by an interrupt
and the indicator PL1 is lit. If the workpiece fails, output CIO 100.01 is
turned ON by an interrupt and indicator PL2 is lit.
• The interrupt program is interrupt task 10.

Additional Capabilities and Restrictions
Restrictions on Highspeed Counter Inputs
• The Phase-Z signal + Software reset method cannot be used when the
high speed counters are operating in Differential Phase or Pulse + Direction Input Modes and the origin search function is enabled for the pulse
output (in the PLC Setup). The Phase-Z signal + Software reset method
can be used when the high speed counters are operating in Incrementing
or Up/Down Input Modes.
• When a high-speed counter is being used (enabled in the PLC Setup), the
input cannot be used as a general-purpose (normal) input, interrupt input,
or quick-response input.
193
Section 5-1
High-speed Counters
Starting Interrupt Tasks based on Comparison Conditions
Data registered in advance in a comparison table can be compared with the
actual counter PVs during operation. The specified interrupt tasks (registered
in the table) will be started when the corresponding comparison condition is
met.
There are two comparison methods available: Target value comparison and
range comparison.
• Use the CTBL(882) instruction to register the comparison table.
• Use either the CTBL(882) instruction or INI(880) instruction to start the
comparison operation.
• Use the INI(880) instruction to stop the comparison operation.
Target Value Comparison
The specified interrupt task is executed when the high-speed counter PV
matches a target value registered in the table.
• The comparison conditions (target values and counting directions) are
registered in the comparison table along with the corresponding interrupt
task number. The specified interrupt task will be executed when the highspeed counter PV matches the registered target value.
• Up to 48 target values (between 1 and 48) can be registered in the comparison table.
• A different interrupt task can be registered for each target value.
• The target value comparison is performed on all of the target values in the
table, regardless of the order in which the target values are registered.
• If the PV is changed, the changed PV will be compared with the target
values in the table, even if the PV is changed while the target value comparison operation is in progress.

Restrictions
A comparison condition (target value and count direction) cannot appear in
the table more than once. An error will occur if a comparison condition is
specified two or more times.
Note When the count direction (incrementing/decrementing) changes at a PV that
matches a target value, the next target value cannot be matched in that direction.

Range Comparison
The specified interrupt task is executed when the high-speed counter PV is
within the range defined by the upper and lower limit values.
• The comparison conditions (upper and lower limits of the range) are registered in the comparison table along with the corresponding interrupt task
number. The specified interrupt task will be executed once when the highspeed counter PV is in the range (Lower limit ≤ PV ≤ Upper limit).
• A total of 8 ranges (upper and lower limits) are registered in the comparison table.
• The ranges can overlap.
• A different interrupt task can be registered for each range.
• The counter PV is compared with the 8 ranges once each cycle.
• The interrupt task is executed just once when the comparison condition
goes from unmet to met.
Restrictions
When more than one comparison condition is met in a cycle, the first interrupt
task in the table will be executed in that cycle. The next interrupt task in the
table will be executed in the next cycle.

Note The range comparison table can be used without starting an interrupt task
when the comparison condition is met. The range comparison function can be
useful when you just want to know whether or not the high-speed counter PV
is within a particular range.
Use the Range Comparison Condition Met Flags to determine whether the
high-speed counter PV is within a registered range.
Pausing Input Signal Counting (Gate Function)
If the High-speed Counter Gate Bit is turned ON, the corresponding highspeed counter will not count even if pulse inputs are received and the counter
PV will be maintained at its current value. Bits A53108 to A53111 are the
High-speed Counter Gate Bits for high-speed counters 0 to 3.
195
Section 5-1
High-speed Counters
When the High-speed Counter Gate Bit is turned OFF again, the high-speed
counter will resume counting and the counter PV will be refreshed.
Restrictions
• The Gate Bit will be disabled if the high-speed counter's reset method is
set to Phase-Z signal + Software reset and the Reset Bit is ON (waiting
for the phase-Z input to reset the counter PV.)
High-speed Counter Frequency Measurement
This function measures the frequency of the high-speed counter (input
pulses.)
The input pulse frequency can be read by executing the PRV(881) instruction.
The measured frequency is output in 8-digit hexadecimal and expressed in
Hz. The frequency measurement function can be used with high-speed
counter 0 only.
The frequency can be measured while a high-speed counter 0 comparison
operation is in progress. Frequency measurement can be performed at the
same time as functions such as the high-speed counter and pulse output without affecting the performance of those functions.

Pulse Outputs
Pulse Frequency Conversion
The pulse frequency input to a high-speed counter can be converted to a rotational speed (r/min) or the PV of the counter can be converted to the total
number of rotations. The converted value is output as 8-digit hexadecimal.
This function is supported only for high-speed counter 0.
Frequency−Rotational Speed Conversion
The rotational speed in r/min is calculated from the pulse frequency input to a
high-speed counter and the number of pulses per rotation.

Pulse Outputs
Overview
Fixed duty factor pulses can be output from the CPU Unit's built-in outputs to
perform positioning or speed control with a servo driver that accepts pulse
inputs.
■ CW/CCW Pulse Outputs or Pulse + Direction Outputs
The pulse output mode can be set to match the motor driver's pulse input
specifications.
197
Section 5-2
Pulse Outputs
■ Automatic Direction Selection for Easy Positioning with Absolute
Coordinates
When operating in absolute coordinates (origin defined or PV changed with
the INI(880) instruction), the CW/CCW direction will be selected automatically
when the pulse output instruction is executed. (The CW/CCW direction is
selected by determining whether the number of pulses specified in the
instruction is greater than or less than the pulse output PV.)
■ Triangular Control
Triangular control (trapezoidal control without a constant-speed plateau) will
be performed during positioning executed by an ACC(888) instruction (independent) or PLS2(887) instruction if the number of output pulses required for
acceleration/deceleration exceeds the specified target pulse Output Amount.
■ Change Target Position during Positioning (Multiple Start)
When positioning was started with a PULSE OUTPUT (PLS2(887)) instruction and the positioning operation is still in progress, another PLS2(887)
instruction can be executed to change the target position, target speed, acceleration rate, and deceleration rate.
■ Switch from Speed Control to Positioning (Fixed Distance Feed Interrupt)
A PLS2(887) instruction can be executed during a speed control (continuous
mode) operation to change to positioning mode (independent mode). This
feature allows a fixed distance feed interrupt (moving a specified amount) to
be executed when specific conditions occur.
■ Change Target Speed and Acceleration/Deceleration Rate during
Acceleration or Deceleration
When trapezoidal acceleration/deceleration is being executed according to a
pulse output instruction (speed control or positioning), the target speed and
acceleration/deceleration rate can be changed during acceleration or deceleration.
■ Use Variable Duty Factor Pulse Outputs for Lighting, Power Control, Etc.
The PULSE WITH VARIABLE DUTY FACTOR instruction (PWM(891)) can be
used to output variable duty factor pulses from the CPU Unit's built-in outputs
for applications such as lighting and power control.

The pulse output mode can be set to CW/CCW pulse
control or Pulse plus direction control, but the same output mode must be used for pulse outputs 0 and 1.
Note The pulse output PVs are stored in the Auxiliary
Area.

tions.
Description
Origin search and origin return operations can be executed through pulse outputs.
• Origin search:
To start the origin search, set the PLC Setup to
enable the origin search operation, set the various
origin search parameters, and execute the ORIGIN
SEARCH instruction (ORG(889)). The Unit will determine the location of the origin based on the Origin
Proximity Input Signal and Origin Input Signal. The
coordinates of the pulse output's PV will automatically
be set as the absolute coordinates.
• Origin return:
To return to the predetermined origin, set the various
origin return parameters and execute the ORIGIN
SEARCH instruction (ORG(889)).
Change the target position during positioning.
(For example, perform
an emergency avoid
operation with the Multiple Start feature.)
Change speed in steps
(polyline approximation) during speed control.
Positioning with the PLS2(887)
instruction
When a positioning operation started with the PULSE
OUTPUT (PLS2(887)) instruction is in progress, another
PLS2(887) instruction can be executed to change the
target position, target speed, acceleration rate, and
deceleration rate.
Use the ACC(888) instruction (continuous) to change the acceleration
rate or deceleration rate.
When a speed control operation started with the
ACC(888) instruction (continuous) is in progress,
another ACC(888) instruction (continuous) can be executed to change the acceleration rate or deceleration
rate.
Change speed in steps Use the ACC(888) instruction (inde- When a positioning operation started with the ACC(888)

Execute positioning with the
PLS2(887) instruction during an
operation started with SPED(885)
(continuous) or ACC(888) (continuous).
When a speed control operation started with the
SPED(885) instruction (continuous) or ACC(888)
instruction (continuous) is in progress, the PLS2(887)
instruction can be executed to switch to positioning, output a fixed number of pulses, and stop.
After determining the
origin, perform positioning simply in absolute
coordinates without
regard to the direction
of the current position
or target position.
Perform triangular control.
The positioning direction is selected
automatically in the absolute coordinate system.
When operating in absolute coordinates (with the origin
determined or INI(880) instruction executed to change
the PV), the CW or CCW direction is selected automatically based on the relationship between the pulse output
PV and the pulse Output Amount specified when the
pulse output instruction is executed.
Positioning with the ACC(888)
instruction (independent) or
PLS2(887) instruction.
When a positioning operation started with the ACC(888)
instruction (independent) or PLS2(887) instruction is in
progress, triangular control (trapezoidal control without
the constant-speed plateau) will be performed if the
number of output pulses required for acceleration/deceleration exceeds the specified target pulse Output
Amount.
(The number of pulses required for acceleration/deceleration equals the time required to reach the target frequency x the target frequency.)

Movement Direction when Using Absolute Pulse Specification
When operating with the absolute pulse specification, the movement direction
is selected automatically based on the relationship between the pulse output
PV when the instruction is executed and the specified target position. The
direction (CW/CCW) specified in an ACC(888) or SPED(885) instruction is not
effective.
Using CW/CCW Limit Inputs for Pulse Output Functions Other than Origin Searches
Pulse outputs will stop when either the CW or CCW limit input signals turns
ON. It is also possible to select whether or not the established origin will be
cleared when a CW or CCW limit input signal turns ON for an origin search or
other pulse output function.
S-curve Acceleration/Deceleration
S-curve acceleration/deceleration can be used for pulse output instructions
involving acceleration/deceleration. When there is leeway in the maximum
allowable speed, S-curve accelerations/decelerations will help control shock
and vibration by reducing the initial acceleration rate in comparison with linear
acceleration/deceleration.
Note
The setting for S-curve acceleration/deceleration applies to all pulse outputs.

The same type of S-curve acceleration/deceleration can be used for

Note The curve for S-curve acceleration/deceleration is formed by applying a cubic
equation to the straight line of the set acceleration/deceleration rates (a cubic
polynomial approximation). The curve’s parameters cannot be changed.
The maximum acceleration will be 1.5 times that of trapezoidal acceleration/
deceleration for the same acceleration/deceleration rate.

Precautions when
using the Pulse
Output Function
The CP1L CPU Unit’s pulse output frequency is determined by dividing the
source clock frequency by an integer ratio. (The source clock frequency for
ports 0 and 1 is 20 MHz and the frequency for ports 2 and 3 is 16.4 MHz.)
Consequently, there may be a slight difference between the set frequency and
the actual frequency, and that difference increases as the frequency
increases. The actual frequency can be calculated from the following equations.

Origin Search and Origin Return Functions
The CP1L CPU Units have two functions that can be used to determine the
machine origin for positioning.
1,2,3...
1. Origin Search
The ORG instruction outputs pulses to turn the motor according to the pattern specified in the origin search parameters. As the motor turns, the origin search function determines the machine origin from the following 3
kinds of position input signals.
• Origin input signal
• Origin proximity input signal
• CW limit input signal and CCW limit input signal
220
Section 5-2
Pulse Outputs
2. Changing the Pulse Output PV
When you want to set the current position as the origin, execute INI(880)
to reset the pulse output PV to 0.
The origin location can be determined after using either method.
The CP1L CPU Units are also equipped with the origin return function, which
can be executed to return the system to the origin after the origin location has
been determined by one of the methods above.
• Origin Return
If the motor is stopped, ORG(889) can be executed to perform an origin
return operation that moves the motor back to the origin position. The origin position must be determined in advance by performing an origin
search or changing the pulse output PV.
Note The motor can be moved even if the origin position has not been determined,
but positioning operations will be limited as follows:
• Origin return: Cannot be used.
• Positioning with absolute pulse specification: Cannot be used.
• Positioning with relative pulse specification: Outputs the specified number
of pulses after setting the current position to 0.
5-2-5-1
Origin Search
When ORG(889) executes an origin search, it outputs pulses to actually move
the motor and determines the origin position using the input signals that indicate the origin proximity and origin positions.
The input signals that indicate the origin position can be received from the
servomotor's built-in phase-Z signal or external sensors such as photoelectric
sensors, proximity sensors, or limit switches.
Several origin search patterns can be selected.
In the following example, the motor is started at a specified speed, accelerated to the origin search high speed, and run at that speed until the origin
proximity position is detected. After the Origin Proximity Input is detected, the
motor is decelerated to the origin search low speed and run at that speed until
the origin position is detected. The motor is stopped at the origin position.

These are the motor speed settings used in the origin search.
Note
The origin search will not be performed in these cases:
Origin search high speed ≤ Origin search proximity speed
Origin search proximity speed ≤ Origin search initial speed
Origin Search/Return Initial Speed
Sets the motor's starting speed when the origin search is executed. Specify
the speed in the number of pulses per second (pps).
Origin Search High Speed
Sets the motor's target speed when the origin search is executed. Specify the
speed in the number of pulses per second (pps).
Origin Search Proximity Speed
Sets the motor's speed after the Origin Proximity Input Signal is detected.
Specify the speed in the number of pulses per second (pps).
Origin Search Acceleration Rate
Sets the motor's acceleration rate when the origin search is executed. Specify
the amount to increase the speed (Hz) per 4-ms interval.
Origin Search Deceleration Rate
Sets the motor's acceleration rate when the origin search function is decelerating. Specify the amount to decrease the speed (Hz) per 4-ms interval.
Origin Compensation
After the origin has been determined, the origin compensation can be set to
compensate for a shift in the Proximity Sensor's ON position, motor replacement, or other change.
231
Section 5-2
Pulse Outputs
Once the origin has been detected in an origin search, the number of pulses
specified in the origin compensation is output, the current position is reset to
0, and the pulse output's No-origin Flag is turned OFF.

Positioning Monitor Time
When the operating mode is set to mode 2, this setting specifies how long to
wait (in ms) for the Positioning Completed Signal after the positioning operation has been completed, i.e., the pulse output has been completed. A Positioning Timeout Error (error code 0300) will be generated if the motor driver's
Positioning Completed Signal does not come ON within the specified time.
Setting range: 0000 to 270F hex (0 to 9,999 ms)
The actual monitoring time will be the Positioning Monitor Time rounded up to
the nearest 10-ms unit + 10 ms max.
If the Positioning Monitor Time is set to 0, the function will be disabled and the
Unit will continue waiting for the Positioning Completed Signal to come ON. (A
Positioning Timeout Error will not be generated.)

An origin search will not be started unless the origin search proximity speed is
less than the origin search high speed and unless the origin search/return initial speed is less than the origin search proximity speed.
Origin Search Error Processing
The CP1L CPU Unit's pulse output function performs a basic error check
before starting to output pulses (when the instruction is executed) and will not
output pulses if the settings are incorrect. There are other errors that can
occur with the origin search function during pulse output, which may stop the
pulse output.
If an error occurs that stops pulse output, the pulse output's Output Stopped
Error Flag will be turned ON and the Pulse Output Stop Error Code will be
written to Error Code word. Use these flags and error codes to identify the
cause of the error.
The Pulse Output Stop Errors will not affect the CPU Unit's operating status.
(The Pulse Output Stop Errors do not cause a fatal or non-fatal error in the
CPU Unit.)

Origin Return
Overview
Moves the motor to the origin position from any other position. The origin
return operation is controlled by ORG(889).
The origin return operation returns the motor to the origin by starting at the
specified speed, accelerating to the target speed, moving at the target speed,
and then decelerating to a stop at the origin position.

ACCELERATION
CONTROL: ACC(888)
Use ACC(888) to set the target frequency and acceleration and deceleration
rate and output pulses with acceleration and deceleration. (Acceleration rate
is the same as the deceleration rate.)
Either independent mode positioning or constant mode speed control is possible when used in combination with PULS(886). ACC(888) can also be executed during pulse output to change the target frequency or acceleration/
deceleration rate, enabling smooth (sloped) speed changes.

The following tables show when a second pulse control instruction can be
started if a pulse control operation is already being executed.
Generally, a second independent-mode positioning instruction can be started
if an independent-mode positioning instruction is being execute, and a second
continuous-mode speed control instruction can be started if a continuousmode speed control instruction is being executed. Operation cannot be
switched between the independent and continuous modes, although
PLS2(887) can be started while ACC(888) (continuous mode) is being executed.
It is possible to start another operation during acceleration/deceleration and
start another positioning instruction during positioning.

Variable Duty Factor Pulse Outputs (PWM(891) Outputs)
Overview
PWM (Pulse Width Modulation) pulse outputs can be output with a specified
duty factor. The duty factor is the ratio of the pulse's ON time and OFF time in
one pulse cycle. Use the PWM(891) instruction to generate variable duty factor pulses from a built-in output.
The duty factor can be changed while pulses are being output.

Note
The frequency can be set up to 6553.5 Hz in the PWM(891) instruction, but
the duty factor accuracy declines significantly at high frequencies because of
limitations in the output circuit at high frequencies.

Remarks
• Absolute pulses can be specified when the origin position has been determined.
• If a target frequency that cannot be reached has been set, the target frequency will be reduced automatically, i.e., triangular control will be performed. In some cases where the acceleration rate is substantially greater
than the deceleration rate, the operation won't be true triangular control.
The motor will be operated at a constant speed for a short time between
the acceleration and deceleration.

Remarks
1,2,3...
1. PLS22(887) used a relative pulse setting. This enables operation even if
the origin is not defined. The present position in A276 (lower 4 digits) and
A277 (upper 4 digits) is set to 0 before pulse output and then contains the
specified number of pulses.
2. ACC(888) can be used instead of SPED(885) for the jog operation. If
ACC(888) is used, acceleration/deceleration can be included in the jog operation.

Inverter Positioning
Features
Simple, accurate high-speed positioning can be achieved using an inverter.
This enables a far more economical positioning system than with a servomotor.
Feedback Control
with Error Counter
A position error counter built into the CP1L CPU Unit enables high-precision
positioning with an Inverter using feedback control. The PULSE OUTPUT
instruction is used in the ladder program in the CP1L CPU Unit to output internal pulses to a built-in error counter.
The error counter calculates the position error from the number of input internal pulses and the number of feedback pulses from the rotary encoder, and
sends speed commands to the inverter so that the position error goes to zero.

Time
Motor
With traditional inverter positioning, positioning patterns are created in which
set positions are detected to trigger changes in the speed. Pulses are read
from the encoder and compared to set values during positioning to enable
determining when a position requiring a speed change has been reached.
This results in positioning errors at speed-change points when stopping at
high speed, reducing stopping precision. To ensure high-precision positioning,
sufficient deceleration was required before stopping, but this increases the
positioning time.
With the CP1L’s inverter positioning function, feedback pulses are used so
that the prevent position is always known, increasing positioning accuracy.
And because preset positioning patterns are used for deceleration and stopping, positioning time is reduced.
280
Section 5-3
Inverter Positioning
Traditional Inverter Positioning
The PLC counts the feedback pulses from the encoder using a high-speed
counter. When a deceleration point is reached, the speed is changed to control the stop position. If the precision of the stop position must be increased,
the stop position must also be detected to control positioning.

The need for low-speed operation near the stopping position
increases the positioning time. PLC

Note
(1) The CP1L’s inverter positioning function is designed to increase positioning speed and stopping precision by reading position information and using a feedback loop with an error counter to switch speeds. It does not
increase the response, stopping precision, or speed change rate of the
inverter and motor. These are characteristics of the inverter and motor.
Refer to user documentation on your inverter and motor for details.
(2) The corresponding pulse output number (0 or 1) cannot be used for the
PULSE WITH VARIABLE DUTY FACTOR instruction (PWM) if inverter
positioning 0 or 1 is used. The high-speed counter of the same number
(0 or 1) is used to input the feedback pulse.

1. To use inverter positioning, the motor and encoder specifications, feedback gain, and other parameters must be set in the PLC Setup. The highspeed counter and inverter must also be set.
2. Pulse output instructions, such as PLS2 or PULS with SPED, are used to
execute positioning. Although normally the pulse output instructions are
used to output pulses from CP1L output contacts, when inverter positioning 0 or inverter positioning 1 is enabled in the PLC Setup, the internal position error counter (called simply the “error counter”) is enabled and the
pulse output instruction will output internal pulses to the error counter. Both
error counters 0 and 1 can be used at the same time.
3. For the number of pulses (i.e., the amount of movement) set in the pulse
output instruction, use the number of feedback pulses from the encoder.
For the pulse frequency set in the pulse output instruction, use the motor
power supply frequency converted to the feedback pulse frequency from
the encoder. (Refer to 5-3-7 Determining the Internal Pulse Output Frequency for details.)
4. Specify an inverter positioning port for the pulse output instruction (port 0:
0020, port 1: 0021). The internal pulses will be output to the error counter
for the specified port.
5. The number of pulses remaining in the error counter is converted to a power supply frequency command for the inverter according to a value set in
the PLC Setup and output to a word in the Auxiliary Area in increments of
0.01 Hz.
6. The frequency command value output to the Auxiliary Area is output to the
inverter from the ladder program according to the inverter command method (i.e., RS-485 communications or analog output). (Refer to 5-3-9 Automatic Calculation of Inverter Frequency Command Value for details.)
284
Inverter Positioning
Section 5-3
7. When a speed command is sent to the inverter, the motor will turn at the
command speed and feedback pulses (i.e., the amount of movement) from
the encoder will be returned to a high-speed counter of the CP1L. The
CP1L will continue to send a speed command to the inverter until the error
counter (i.e., the position error) goes to zero, i.e., until positioning has been
completed.
8. When the error counter goes to zero, the speed command to the inverter
will also go to zero. Even after the completion of internal pulse output (i.e.,
position command) from the pulse output instruction, the CP1L will maintain the error counter so that is remains at zero.
9. The status of the error counter (such as the command direction and in-position status) will be stored in the Auxiliary Area. This status can be read
from the user program to enable controlling output of commands to the inverter.
For example, if a change in the load causes the motor shaft to turn, feedback
pulses from the encoder will enter the error counter, the value in the error
counter will be reduced, and the Reverse Command Flag in the Auxiliary Area
will turn ON. By writing the ladder program to output a reverse operation command to the inverter for the Reverse Command Flag, a command in the opposite direction of motor shaft movement will be output from the CP1L to the
inverter, causing the motor to return to its original position. This compensating
operation to continuously maintain the current stop position is called a servo
lock.
Other Functions
Servo Locks with Vector
Control Inverters
The servo lock on an inverter can be used to stop positioning. By using the
inverter’s servo lock, the inverter positioning function and the output command
to the inverter can be stopped from the user program without using feedback
control even if the error counter value is not zero. This enables servo locks
when using an inverter with vector control.
Clearing the Error Counter
for Errors
If the motor shaft is moved manually for error stops or when the inverter is
stopped, feedback pulses will accumulate in the error counter. This can be
very dangerous because it may cause the motor to suddenly return to the
original position at high speed when operation is started again. To prevent
such problems, an error counter error output can be produced when more
than a set number of pulses accumulated in the error counter when positioning operations are stopped.

Low-speed Operation
Using Minimum Output
Setting
An inductive motor driven with an inverter is different from a servomotor in that
the torque at low speeds is so low that it may not be possible to turn the motor
shaft at the minimum frequency. The CP1L provide a minimum output setting
the ensure a minimum output to enable positioning at low speeds even when
there are extremely few pulses in the error counter.
Absolute Positioning
The amount of movement (i.e., amount of rotation) is input to the high-speed
counter as feedback pulses. During inverter positioning, the present value of
the high-speed counter can be used as an absolute position.
Note
5-3-4
The absolute position will change if the present value of the high-speed
counter is changed or the high-speed counter is reset.

PLC Setup to automatically calculate the inverter frequency command
values and store it in A23/A33 in increments of 0.01 Hz.
• For serial communications, the ladder program is used to output the value
in A23/A33 to the inverter using serial communications.
• For analog output, the value in A23/A33 can be scaled to analog output
values and output from the Analog Unit to the inverter.

Determining the Internal Pulse Output Frequency
Use the following formula to calculate the internal pulse frequency (Hz) to output from the pulse output instruction (e.g., PLS2) based on the power supply
frequency (Hz) to be output from the inverter to the motor.

frequency to
motor (Hz)
(1) Calculate the power supply frequency for one revolution per second from
the motor specifications. For example, with a 1,800-r/min (60-Hz) motor
(30 r/s), the power supply frequency for one revolution per second would
be calculated as follows: 60 [Hz] ÷ 30 [r/s] = 2 [Hz].
295
Section 5-3

(2) The encoder resolution times the counter multiplier times the gear ratio
equals the number of pulses output by the encoder for one motor shaft
revolution.

For example, to output a power supply frequency of 10 Hz to the motor:

Therefore, set a pulse output frequency of 5 kHz in the pulse output instructions (e.g., PLS2).

Automatic Calculation of Inverter Frequency Command Value
Set the Power Supply Frequency for One Motor Revolution per Second, Number of Encoder Pulses for One Motor Revolution, and Error Counter Cycle in
the PLC Setup to automatically calculate the inverter frequency command
value and store it in A23 for inverter positioning 0 and A33 for inverter positioning 1.
Note
The inverter frequency command values are stored in A23 and A33
in increments of 0.01 Hz. Divide the value in A23 or A33 by 100 to
obtain the value in hertz.
The values stored in A23 and A33 can be used in converting the output value
to the frequency command value for the inverter. This value can be output to
the inverter from the program using serial communications or an Analog Output Unit.
Note
The following formula is used inside the PLC to automatically calculate the inverter frequency command value from the output value
(i.e., the error counter present value multiplied by the gain). (The
output value is stored in A20 and A21 for inverter positioning 0 and
in A30 and A31 for inverter positioning 1.)

Note: The inverter frequency command value is stored in A23/A33 in increments of 0.01 Hz.
Note
(1) Calculate the power supply frequency for one revolution per second from
the motor specifications. For example, with a 1,800-r/min (60-Hz) motor
(30 r/s), the power supply frequency for one revolution per second would
be calculated as follows: 60 [Hz] ÷ 30 [r/s] = 2 [Hz].
(2) The encoder resolution times the counter multiplier times the gear ratio
equals the number of pulses output by the encoder for one motor shaft
revolution.

If the frequency command unit set in the inverter is 0.1 Hz, divide the command frequency in A23 or A33 by 10.
The following example is for the CP1W-DA041.
The analog output resolution is 6,000, so the command value calculated

Present Values of High-speed Counter and Pulse Outputs
The present value of the high-speed counter when inverter positioning is used
is stored in the same memory location as for normal high-speed counter application. This value can be used as the present value of feedback pulses from
the encoder, i.e., as the absolute position of inverter positioning. Target value
and range comparisons for high-speed counters are also valid.
The present value of the pulse output (A276/A277 or A278/A279), i.e., the
pulse output value to the error counter, is an absolute position if an absolute
coordinate system is specified and is a relative position if a relative coordinate
system is specified.

Note
When start input CIO 1.04 turns ON, 600,000 pulses are output internally for
inverter positioning 0 to turn the motor shaft.
Refer to 5-3-7 Determining the Internal Pulse Output Frequency for the formula to convert the frequency and use the converted internal pulse frequency.
The number of output pulses is calculated from the encoder specifications
and the high-speed counter multiplier.

Referencing the
Automatically Calculated
Inverter Frequency
Command Value
If the following settings are made in the PLC Setup, the inverter frequency
command value will be calculated automatically and set in A23 in the Auxiliary
Area. These settings are on the Inverter Positioning 0 Tab Page in the PLC
Setup.
• Power Supply Frequency for One Motor Revolution per Second (0.1-Hz
increments)
• Number of Encoder Pulses for One Motor Revolution
• Error Counter Cycle (x 4 ms)
The inverter frequency command value in A23 is accessed and converted to
an analog output signal. The CP1W/CPM1A-DA041 has a resolution of 6,000,
so the conversion to an analog signal is performed as follows:
6,000 ÷ 60 Hz (inverter’s maximum output frequency) ÷ 100 = 1
The conditions are as follows:

5-3-13 Supplemental Information
Restrictions
• Inverter positioning 0 and inverter positioning 1 each use one high-speed
counter and one serial port (except that a serial port is not used when an
Analog Output Unit is used). (High-speed counter 0 is allocated to inverter
positioning 0 and high-speed counter 1 is allocated to inverter positioning
1.)
• When inverter positioning 0 or 1 is used, the corresponding pulse output
(0 or 1) and the corresponding PWM command (pulse output 0 or 1) cannot be used.
Precautions
• Determine the in-position range based on the mechanical system. Use a
smaller range if positioning precision is required. If the range is too small,
however, time may be required when stopping. If stopping quickly is more
important than precision, increase the in-position range.
• The error counter cycle also affects the conversion between the output
value and the inverter frequency command value. Refer to 5-3-9 Automatic Calculation of Inverter Frequency Command Value for details.
• If inverter positioning does not end normally, adjust the following settings.
Reduce the acceleration/deceleration rates.
Lower rates will stabilize operation at the end of acceleration/deceleration.
Reduce the target frequency.
Change the error counter cycle. Increasing the error counter cycle improve
stopping precision, but it may also cause unstable speeds during operation.
Adjust the gain.
Increasing the gain will improve stopping precision, but it may also cause
unstable speeds during operation.

Interrupt Functions

6-1-1
Interrupt Functions
Overview of CP1L Interrupt Functions
The CP1L CPU Unit’s processing is normally cyclical (overseeing processing
→ program execution → I/O refreshing → peripheral servicing), with cyclic
tasks executed in the program execution stage of the cycle. The interrupt
functions can be used to temporarily interrupt this cyclic processing and execute a particular program when a predefined condition occurs.
Types of Interrupt
Functions
Input Interrupts (Direct
Mode)
When one of the CPU Unit’s built-in inputs goes from OFF to ON (or ON to
OFF), the corresponding interrupt task is executed. Interrupt tasks 140 to 145
are allocated to the 8 input terminals used for the input interrupts.
Input Interrupts (Counter
Mode)
This function counts input pulses at one of the CPU Unit’s built-in inputs and
executes the corresponding interrupt task when the count reaches the SV.
The maximum input response frequency for input interrupts (in counter mode)
is 5 kHz.
Scheduled Interrupts
This function executes an interrupt task at a fixed time interval measured by
the CPU Unit’s built-in timer. The time interval units can be set to 10 ms, 1 ms,
or 0.1 ms. The minimum timer SV is 0.5 ms.
Interrupt task 2 is allocated to scheduled interrupt.
This function counts input pulses with the CPU Unit’s built-in high-speed
counter and executes an interrupt task when the count reaches the preset
value or falls within a preset range (target-value or zone comparison). An
interrupt task between 0 and 255 can be allocated with an instruction.
High-speed Counter
Interrupts
Refer to 5-1 High-speed Counters for details on high-speed counters.
Note
Power OFF interrupts cannot be used with CP1L CPU Units.
Creating an Interrupt
Task Program
1,2,3...
338
1. Right-click NewPLC1 [CP1L] Offline in the project workspace and select
Insert Program from the pop-up menu. A new program called
NewProgram2 (unassigned) will be inserted in the project workspace.
Section 6-1
Interrupt Functions
2. Right-click NewProgram2 (unassigned) and select Properties from the
pop-up menu to display the Program Properties Window.
3. Set the Task type in the Program Properties Window.
In this example, interrupt task 140 was allocated to NewProgram2.
If you click the X Button in the upper-right corner of the window, you can create the program that will be executed as interrupt task 140.
The programs allocated to each task are independent and an END(001)
instruction must be input at the end of each program.
Interrupt Task Priority
The input interrupts (direct mode and counter mode), high-speed counter
interrupts, scheduled interrupts, and external interrupts all have the same priority. If interrupt task A (an input interrupt, for example) is being executed
when interrupt task B (a scheduled interrupt, for example) is called, task A
processing will not be interrupted. Task B processing will be started when task
A is completed.
If two different types of interrupt occur simultaneously, they are executed in
the following order:
Input interrupt
(direct mode or
counter mode)
>
High-speed
counter interrupt
>
Scheduled
interrupt
If two of the same type interrupt occur simultaneously, the task with the lower
interrupt task number is executed first.
Note
Duplicate Processing
in Cyclic and Interrupt
Tasks
If a user program is likely to generate multiple interrupts simultaneously, the
interrupt tasks will be executed in the order shown above, so it may take some
time from the occurrence of the interrupt condition to the actual execution of
the corresponding interrupt task. In particular, it is possible that scheduled
interrupts will not be executed in the preset time, so the program must be
designed to avoid interrupt conflicts if necessary.
If a memory address is processed both by a cyclic task and an interrupt task,
an interrupt mask must be set to disable interrupts.
339
Section 6-1
Interrupt Functions
When an interrupt occurs, execution of the cyclic task will be interrupted
immediately, even during execution of a cyclic task’s instruction, and the partially processed data is saved. After the interrupt task is completed, processing returns to the cyclic task and the interrupted processing restarts with the
data saved before the interrupt processing. If the interrupt task overwrites a
memory address used by one of the interrupted instruction’s operands, that
overwrite may not be reflected after the saved data is restored as processing
returns to the cyclic task.
To prevent an instruction from being interrupted during processing, enter
DI(693) just before the instruction to disable interrupts and EI(694) just after
the instruction to enable interrupts again.
a. The following example shows duplicate processing by an interrupt
task, which interrupts processing of a +B instruction between the first
and third operands and overwrites the same memory address.

The interrupt occurs during processing of the +B instruction and the result is
saved temporarily without being written to the destination word (D0).
The interrupt task transfers the value of #0010 to D0, but the saved result of
the +B instruction (1235) is written to D0 when processing returns to the cyclic
task. In the end, the interrupt task’s processing has no effect.

Input Interrupts (Counter Mode)
Overview
This function counts up-differentiated or down-differentiated input signals and
executes an interrupt task when the count reaches the set value.
• The counter-mode input interrupts use the same input terminals as the
direct-mode input interrupts. Refer to 6-1-2 Input Interrupts (Direct Mode)
for details.
• The counter input mode can be set to up or down (incrementing or decrementing) with MSKS(690).
• The counter-mode input interrupts start the same interrupt tasks (140 to
145) as the direct-mode input interrupts.
• The maximum input response frequency is 5 kHz total for all countermode input interrupts.

Note
• Write the programs for the corresponding

• Use MSKS(690) to specify up-differentiation
or down-differentiation.
• Use MSKS(690) to enable input interrupts (in
counter mode).
The input interrupt (counter mode) function is one of the input interrupt functions and executes an interrupt based on the pulse count. If the input pulse
frequency is too high, interrupts will occur too frequently and prevent normal
cyclic task processing. In this case, cycle time too long errors may occur or
the pulse input may not be read.
The maximum total frequency of the counter-mode interrupt inputs is 5 kHz.
Even in this case, the high frequencies may adversely affect other devices’
operation or the system load, so check the system’s operation thoroughly
before using the counters at high frequencies.

The procedures for using the CX-Programmer to set the PLC Setup are the
same as the procedures for input interrupts (direct mode). Refer to 6-1-2 Input

Scheduled Interrupts
This function executes an interrupt task at a fixed time interval measured by

Procedure
Set the PLC Setup.
• Use the CX-Programmer to set the scheduled
interrupt timer units in the PLC Setup.
↓
Write the ladder program.
PLC Setup
350
• Write the program allocated to interrupt task
2 (scheduled interrupt task).
• Use MSKS(690) to specify the timer SV.
Click the Timings Tab and set the input function to Scheduled Interrupt Interval (the scheduled interrupt timer’s units). The timing units can be set to 10
ms, 1 ms, or 0.1 ms. The scheduled interrupt timer SV is calculated by multiplying this interval setting by the timer SV set with MSKS(690).
Section 6-1
Interrupt Functions
Scheduled Interrupt Interval Setting
Note
(1) Set a scheduled interrupt time (interval) that is longer than the time required to execute the corresponding interrupt task.
(2) If the scheduled time interval is too short, the scheduled interrupt task will
be executed too frequently, which may cause a long cycle time and adversely affect the cyclic task processing.
(3) If an interrupt task is being executed for another interrupt (input interrupt,
high-speed counter interrupt, or external interrupt) when the scheduled
interrupt occurs, the scheduled interrupt will not be executed until the other interrupt task is completed.
When different kinds of interrupts are being used, design the program to
handle multiple interrupts smoothly. Even if two interrupts occur at the
same time, the scheduled interrupts will continue as programmed, so the
scheduled interrupt tasks will continue to occur at the scheduled times
even if specific scheduled interrupts are delayed.
Writing the Ladder
Program
MSKS(690) Settings
The MSKS(690) instruction must be executed in order to use the scheduled

Quick-response Inputs
Overview
The quick-response inputs can read pulses with an ON time shorter than the
cycle time (as short as 50 µs). Use the quick-response inputs to read signals
shorter than the cycle time, such as inputs from photomicrosensors.
PLC Setup
Use the CX-Programmer to set a built-in input as a quick-response input in the
PLC Setup. Click the Built-in Input Tab to display the Interrupt Input settings
(at the bottom of the tab). Set the input function from Normal to Quick for each
input that will be used as a quick-response input.
Bit Allocation for
Quick-Response

No-protocol Communications
No-protocol communications enable sending and receiving data using the
TRANSMIT (TXD(236)) and RECEIVE (RXD(235)) instructions without using
a protocol and without data conversion (e.g., no retry processing, data type
conversion, or process branching based on received data). The communications mode for the serial port must be set for no-protocol communications in
the PLC Setup.
No-protocol communications are used to send data in one direction to or from
standard devices that have an RS-232C or RS-422A/485 port using TXD(236)
or RXD(235).

Modbus-RTU Easy Master Function
Overview
If an RS-232C or RS-422A/485 Option Board is used, the CP1L CPU Unit can
function as a Modbus-RTU Master to send Modbus-RTU commands by
manipulating software switches. This enables easily controlling Modbus-compliant slaves, such as Inverters, through serial communications.
The following OMRON Inverters support Modbus-RTU slave operation:
3G3JV, 3G3MV, and 3G3RV.
The communications mode in the PLC Setup must be set to the Gateway
Mode to enable this functionality.
371
Section 6-3
Serial Communications
Modbus-RTU commands can be set simply by turning ON a software switch
after setting the Modbus slave address, function, and data in the DM fixed
allocation words for the Modbus-RTU Easy Master. The response when
received is also store in the DM fixed allocation words for the Modbus-RTU
Easy Master.

Communications are easily achieved
by simply by turning ON A641.00
after setting the Modbus-RTU
command in the DM fixed allocation
words.

Communications: Smart Active Parts and Function Blocks
Overview
OMRON components that support CompoWay/F communications or ModbusRTU slave functionality (such as Temperature Controllers) can be easily
accessed from a CP1L CPU Unit equipped with an RS-422A/485 or RS-232C
Option Board using Smart Active Parts (SAPs) on an NS-series PT or using
function blocks in the ladder program in the CP1L CPU Unit.
The communications mode in the PLC Setup must be set to the Gateway
Mode to enable this functionality.
Note

Serial Gateway Function
When a FINS command is received, it is automatically converted to the protocol corresponding to the message and sent on the serial communications
path. Responses are also converted in the same way.
Note
Serial ports 1 and 2 on the CP1L CPU Unit can be used to convert to the following protocols.
• CompoWay/F
• Modbus-RTU
This functionality is enabled when the serial communications mode is set to
Serial Gateway.

Serial PLC Links
Overview
Serial PLC Links can be used to allow data to be exchanged among CP1L
and CJ1M CPU Units via the RS-422A/485 or RS-232C Option Boards
mounted to the CPU Units without requiring special programming. The communications mode in the PLC Setup must be set to the Serial PLC Link Mode
to enable this functionality.
• Either serial port 1 or 2 can be used. (See note.)
• Words are allocated in memory in the Serial PLC Link Words (CIO 3100
to CIO 3199).
• A maximum of 10 words can be transferred by each CP1L CPU Unit, but
the number of linked words can be set to fewer words. (The size must be
the same for all CP1L CPU Units.)
Note
376
Serial PLC Links cannot be used on serial ports 1 and 2 at the same time. If
one port is set as a Serial PLC Link slave or master, it will not be possible to
set the other port for a Serial PLC Link. A PLC Setup error will occur if an
attempt is made to set both ports for Serial PLC Links.

The data for all the Polled Units in the Serial PLC Links ar reflected in the Polling Unit only, and each Polled Unit reflects the data of the Polling Unit only.
The advantage of the Polling Unit link method is that the addresses allocated
for the local Polled Unit data are the same in each Polled Unit, allowing data to
be accessed using common ladder programming. The areas allocated for the
unit numbers of the PT or Polled Units not present in the network are undefined in the Polling Unit only.

Example: Polling Unit Link Method, Highest Unit Number: 3
In the following diagram, Polled Unit No. 2 is a PT or a Unit not participating in
the network, so the corresponding area in the Polling Unit is undefined.

Example: Polling Unit Link Method, Number of Link Words: 10
The CPU Unit that is the Polling Unit (either CP1L or CJ1M) sends its data
(CIO 3100 to CIO 3109) to the same words (CIO 3100 to CIO 3109) in all
other CPU Units. The Polled Units send their data (CIO 3110 to CIO 3119) to
consecutive sets of 10 words in the Polling Unit. The Polling Units is a CP1L
CPU Unit in the following example, but it could also be a CJ1M CPU Unit.

1:1 Links
Two PLCs can be connected through their RS-232C ports to create Link
Areas.
Applicable PLCs
A 1:1 Link can be create between any of the following SYSMAC PLCs:
CP1L, CQM1H, C200HX/HG/HE(-Z), CPM1A-V1, CPM2A, CPM2B, CPM2C,
and SRM1(-V2)
Connections
To create a 1:1 Link, connect the RS-232C ports on the two PLCs.

Slave
CP1L PLC
RS-232C
C-series PLC
CPM1A-V1
CPM2
CQM1H
C200HX/HG/HE
Etc.
1:1 Link
PLC Setup
Set the PLC to a 1:1 Link Master or a 1:1 Link Slave in the PLC Setup. Set the
other PLC to the opposite setting.
Link Area Size
The 1:1 Link Area in the CP1L is from CIO 3000 to CIO 3015 (16 words).
Even if a 1:1 Link is created with a CQM1H or C200HX/HG/HE(-Z) PLC, the
1:1 Link Area will be only 16 words on both sides of the link, and only LR 00 to
LR 15 will be used in the CQM1H or C200HX/HG/HE(-Z) PLC. LR 16 to LR 63
cannot be used for 1:1 Links
Operation
Here, operation is described assuming that the master is the CP1L and the
slave is the CPM2A.

Any data written to these words with the OUT or MOV instructions will be
automatically transferred to LR 00 to LR 07 in the CPM2A. The CPM2A will
use these words as its read area.
CIO 3008 to 3015 are the read area of the CP1L. The contents of LR 08 to
LR 15 in the CPM2A will automatically be transferred to CIO 3008 to 3015 in
the CP1L. The words in the PLC’s read area cannot be written using the OUT,
MOV, or any other write instructions.

1:1 NT Links
The NT Link communications protocol was developed to enable high-speed
communications between PLC and Programmable Terminals (PTs). There are
two communications modes supported by the NT Link protocol: 1:1 NT Links,
in which one PLC is connected to one PT, and 1:N NT Links, in which one
PLC is connected to more than one PT.
Connections
With the NT Link protocol, the PLC automatically responds to commands sent
from the PT, so no communications programming is required in the CP1L.

Battery-free Operation
Overview
With the CP1L CPU Unit, saving backup data in the built-in flash memory
(non-volatile memory) enables operation with no battery mounted (i.e., battery-free operation).
I/O memory (such as CIO), however, is constantly refreshed during operation,
so backup data is not saved in the built-in flash memory. When battery-free
operation is used, therefore, programs must be created assuming that I/O
memory data will not be saved.
For example, if a battery is mounted, then HR, CNT, and DM data is saved
during power interruptions if a battery is mounted but not when battery-free
operation is used.
394
Section 6-5
Battery-free Operation
In that case it is necessary to set the required values in the ladder program. It
is also possible to save to the built-in flash memory in advance the DM initial
values that are to be set for the DM on RAM at startup.
6-5-2
Using Battery-free Operation
Precautions when
Creating Programs
for Battery-free
Operation
Be careful of the following points, and create programs for which it will not be
a problem even if the correct I/O memory values are not held.
• For unstable parts of I/O memory, include programming at the start of
operation to set required data.
• When battery-free operation is used, the Output OFF Flag (A500.15) in
the Auxiliary Area becomes unstable. When the Output OFF Flag turns
ON, all outputs turn OFF, so include the following program for clearing the
Output OFF Flag at the start of operation.
First Cycle Flag
RSET
A200.11
A500.15
• Do not reference the clock function, (the clock data in words A351 to A354
of the Auxiliary Area, or the various kinds of time data).
Saving DM Initial
Values (Only when
Required)
1,2,3...
Use the following procedure to save to the built-in flash memory the DM initial
values that are to be set at startup.
1. First set in the DM Area the data that is to be set as initial values at startup.
2. Execute a backup to flash memory from the CX-Programmer's Memory
Cassette Transfer/Data Memory Backup Dialog Box.
The procedure is as follows:
a. Select PLC - Edit - Memory Cassette/DM.
The following Memory Cassette Transfer/DM Backup Dialog Box will
be displayed.
395
Section 6-6
Memory Cassette Functions
b.
Note
Select the Data Memory Option in the Backup to Flash Memory Area
and click the Backup Button.
The DM data will be written to the built-in flash memory.
The DM data that is saved and written at startup is the entire DM Area (D0 to
D32767).
PLC Setup
1,2,3...
1. Set Do not detect Low Battery (run without battery) to Do not detect.
2. Set IOM Hold Bit Status at Startup and Forced Status Hold Bit Status at
Startup to Clear (OFF).
3. Set Read DM from flash memory to Read. (Only when DM initial values
have been saved as described above.)
!Caution The CP1L CPU Units automatically back up the user program and parameter
data to flash memory when these are written to the CPU Unit. Also, the CXProgrammer can be used to save all of the data in the DM Area to the flash
memory for use as initial values when the power supply is turned ON. Neither
of these functions saves the I/O memory data (including HR Area data,
counter PVs and Completion Flags, and DM Area data other than initial values). The HR Area data, counter PVs and Completion Flags, and DM Area
data other than initial values are held during power interruptions with a battery. If there is a battery error, the contents of these areas may not be accurate after a power interruption. If HR Area data, counter PVs and Completion
Flags, and DM Area data other than initial values are used to control external
outputs, prevent inappropriate outputs from being made whenever the Battery
Error Flag (A402.04) is ON.

Memory Cassette Functions
Overview
CP1L CPU Units have Memory Cassette functions that enable data in the
CPU Unit to be stored on and read from a special CP1W-ME05M Memory
Cassette. These functions can be used for the following applications.
• Copying data to other CPU Units to produce duplicate devices.
• Backing up data in case the CPU Unit needs to be replaced due to any
malfunction.
• Writing and updating data when existing device versions are upgraded.
Note

Built-in flash memory (DM Initial Values Area)
The areas for storing various types of data have fixed allocations in the Memory Cassette, and a single Memory Cassette corresponds to a single CPU
Unit.
Therefore it is not possible to simultaneously store multiple items of the same
type of data (e.g., two user programs).
Also, the data can only be read to a CPU Unit. It cannot be directly managed
from a personal computer like files.
The only data that can be stored on a Memory Cassette is the data from a
CPU Unit.
Note
6-6-2
The CX-Programmer's function for saving DM initial values is used for saving
the values in the DM Area (D0 to D32767) to the built-in flash memory as initial values. By means of a setting in the PLC Setup, these initial values can
then be automatically written to the DM Area (D0 to D32767) when the power
is turned ON.

• In order for Memory Cassette data to be transferred, the Memory Cassette must be mounted in the CPU Unit.
• The BKUP indicator will light while data is being transferred to or verified
in a Memory Cassette. Never turn OFF the power to the PLC or remove
the Memory Cassette while the BKUP indicator is lit. Doing either may
make it impossible to use the Memory Cassette.
• Memory Cassette data transfers and verification are possible only when
the CPU Unit operating mode is PROGRAM mode. The Memory Cassette
transfer function cannot be used in either RUN or MONITOR mode.
• When using automatic transfer from a Memory Cassette at startup, be
sure to transfer the data to the Memory Cassette if any changes are made
using online editing.
• The operating mode cannot be switched from PROGRAM mode to RUN
or MONITOR mode while a Memory Cassette data transfer or verification
is in progress.
• The following table shows whether data transfers are enabled when the
CPU Unit is protected in various ways.

• Prohibiting creating a program file for file memory
6-7-1
Read Protection
Overview
It is possible to read-protect individual program tasks (called task read protection) or the entire user program (called UM read protection).
Read protection prevents anyone from displaying or editing the read-protected
set of tasks or entire user program from CX-Programmer without inputting the
correct password. If the password is input incorrectly five times consecutively,
password input will be disabled for two hours, providing even better security
for PLC data.
Operating Procedure
1,2,3...
404
1. Go online and select PLC - Protection - Release Password. The following Release Read Protection Dialog Box will be displayed.
Section 6-7
Program Protection
2. Input the password. If the password is incorrect, one of the following messages will be displayed and protection will not be released.
UM Read Protection
Task Read Protection
3. If an incorrect password is input five times consecutively, read protection
will not be released even if the correct password is input on the sixth attempt and displaying and editing the entire user program or the specified
tasks will be disabled for two hours.
Read Protection for Individual Tasks Using Passwords
Overview
It is possible to read-protect individual program tasks (referred to as “task
read protection” below) or the entire PLC. The same password controls
access to all of the read-protected tasks.
Task read protection prevents anyone from displaying or editing the read-protected set of tasks from CX-Programmer without inputting the correct password. In this case, the entire program can be uploaded, but the read-protected
tasks cannot be displayed or edited without inputting the correct password.
Tasks that are not read-protected can be displayed, edited, or modified with
online editing.
Note Task read protection cannot be set if UM read protection is already set. However, it is possible to set UM read protection after task read protection has
been set.

Note
1. If the CX-Programmer is used to read a task with task read protection applied, an error will occur and the task will not be read. Likewise, if the PT
Ladder Monitor function is used to read a password protected task, an error will occur and the task will not be read.
2. The entire program can be transferred to another CPU Unit even if individual tasks in the program are read-protected. The task read protection will
remain in effective for the password-protected tasks.
3. When the CX-Programmer is used to compare a user program in the computer's memory with a user program in the CPU Unit, password-protected
tasks will be compared too.
Restrictions to Function
Block Use
Function block definitions can be read even if the entire program or individual
tasks in a program containing function blocks are read-protected. If required,
set read protection individually for each function block.
Prohibiting Backing Up
the Programs to a Memory
Cassette
Overview
When a password is set for the entire user program or for a task from the CXProgrammer, prohibiting backing up the user program can be set as an option.
Doing so will make it impossible to upload PLC data to the CX-Programmer
and make it impossible to save PLC data offline to a storage device.

It is possible to prohibit write operations and other editing operations sent to
the PLC's CPU Unit as FINS commands through a network (including write
operations from CX-Programmer, CX-Protocol, CX-Process, and other applications using Fins Gateway). Read processes are not prohibited.
FINS write protection can disable write processes such as downloading the
user program, PLC Setup, or I/O memory, changing the operating mode, and
performing online editing.
It is possible to exclude selected nodes from write protection so that data can
be written from those nodes.
An event log in the CPU Unit automatically records all write processes sent
through the network and that log can be read with a FINS command.
6-7-3
Protecting Program Execution Using the Lot Number
The lot number is stored in A310 and A311 and can be used to prevent the
program from being executed on a CPU Unit with the wrong lot number.
The following instructions can be added to the program to create a fatal error
and thus prevent program execution if an attempt is made to execute the program on a CPU Unit with the incorrect lot number. A password can also be set
to read-protect the program so that it cannot be copied, e.g., using a Memory
Cassette.
The lot number stored in A310 and A311 cannot be changed by the user.
The upper digits of the lot number are stored in A311 and the lower digits are
stored in A310, as shown below.

6-8-1
Failure Alarm Instructions: FAL(006) and FALS(007)
The FAL(006) and FALS(007) instructions generate user-defined errors.
FAL(006) generates a non-fatal error that allows program execution to continue and FALS(007) generates a fatal error that stops program execution.
When the user-defined error conditions (i.e., the execution conditions for
FAL(006) or FAL(007)) are met, the instruction will be executed and the following processing will be performed.
1,2,3...
1. The FAL Error Flag (A402.15) or FALS Error Flag (A401.06) is turned ON.
2. The corresponding error code is written to A400.
3. The error code and time of occurrence are stored in the Error Log.
4. The error indicator on the front of the CPU Unit will flash or light.
5. If FAL(006) has been executed, the CPU Unit will continue operating.
If FALS(007) has been executed, the CPU Unit will stop operating. (Program execution will stop.)

6-8-2
Failure Point Detection: FPD(269)
FPD(269) performs time monitoring and logic diagnosis. The time monitoring
function generates a non-fatal error if the diagnostic output isn’t turned ON
within the specified monitoring time. The logic diagnosis function indicates
which input is preventing the diagnostic output from being turned ON.
Time Monitoring
Function
FPD(269) starts timing when it is executed and turns ON the Carry Flag if the
diagnostic output isn’t turned ON within the specified monitoring time. The
Carry Flag can be programmed as the execution condition for an error processing block. Also, FPD(269) can be programmed to generate a non-fatal
FAL error with the desired FAL number.
When an FAL error is generated, a preset message will be registered and can
be displayed on the CX-Programmer. FPD(269) can be set to output the
results of logic diagnosis (the address of the bit preventing the diagnostic output from being turned ON) just before the message.
The teaching function can be used to automatically determine the actual time
required for the diagnostic output to go ON and set the monitoring time.
Logic Diagnosis
Function
FPD(269) determines which input bit is causing the diagnostic output to
remain OFF and outputs the result. The output can be set to bit address output (PLC memory address) or message output (ASCII).
If bit address output is selected, the PLC memory address of the bit can be
transferred to an Index Register and the Index Register can be indirectly
addressed in later processing.
414
Section 6-8

If the message output is selected, an error message can be displayed on the
CX-Programmer at the same time as a FAL error is generated for time monitoring.

Note Use the same methods as for actual system errors to clear the simulated system errors. Refer to the 10-2 Troubleshooting for details. All system errors
simulated with FAL(006) and FALS(007) can be cleared by cycling the power
supply.
6-8-4
Output OFF Bit
As an emergency measure when an error occurs, all outputs from Output
Units can be turned OFF by turning ON the Output OFF Bit (A500.15). The
operating mode will remain in RUN or MONITOR mode, but all outputs will be
turned OFF.
Note Normally (when IOM Hold Bit = OFF), all outputs from Output Units are turned
OFF when the operating mode is changed from RUN/MONITOR mode to
PROGRAM mode. The Output OFF Bit can be used to turn OFF all outputs
without switching to PROGRAM mode.
Application Precaution for
DeviceNet
416
When the CPM1A-DRT21 is used, all slave outputs will be turned OFF, i.e., all
inputs to the master will be OFF.

If an input is below the range
(i.e., less than 3.2 mA), the
open-circuit detection function is activated and the data
becomes 8,000.
For analog inputs, the averaging function operates when the averaging bit is
set to 1. The averaging function outputs the average (a moving average) of
the last eight input values as the converted value. If there is only a slight variation in inputs, it is handled by the averaging function as a smooth input.
The averaging function stores the average (a moving average) of the last eight
input values as the converted value. Use this function to smooth inputs that
vary at a short interval.
Open-circuit Detection
Function
The open-circuit detection function is activated when the input range is set to
1 to 5 V and the voltage drops below 0.8 V, or when the input range is set to 4
to 20 mA and the current drops below 3.2 mA. When the open-circuit detection function is activated, the converted data will be set to 8,000.
The time for enabling or clearing the open-circuit detection function is the
same as the time for converting the data. If the input returns to the convertible
range, the open-circuit detection is cleared automatically and the output
returns to the normal range.

For example, if analog input device 2 is outputting 5 V and the same power
supply is being used as shown above, about 1/3, or 1.6 V, will be applied at
the input for input device 1.
Consider the following information on open input circuits when using voltage
inputs. Either use separate power supplies, or install an isolator at each input.
If the same power supply is used as shown in the following diagram and an
open circuit occurs at point A or B, an unwanted current flow will occur as
shown by the dotted lines in the diagram, creating a voltage at the other input
of about 1/3 to 1/2. If the 1 to 5-V range is being used, the open-circuit detection function will not operate. Also, if there is an open circuit at C, the open-circuit detection function will not operate because the negative sides are the
same.

Allocating I/O Words
Four input words and two output words are allocated from the next words following the last I/O words allocated to the CPU Unit or an existing Expansion
Unit or Expansion I/O Unit.

Write the settings for input use, averaging use, and range codes for words n+1
and n+2. When the set data is transferred from the CPU Unit to the Analog I/O
Unit, the A/D conversion will be started.

• The Analog Input Unit will not start converting analog I/O values until the
range code has been written.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
Averaging
Set whether averaging is to be used for set data. When the averaging bit is set
to 1, the average (moving average) for the past eight inputs is output as conversion data.
Reading Analog Input
Conversion Values
Read the conversion value storage area with the ladder program. With word m
as the last input word allocated to the CPU Unit or an already-connected
Expansion Unit, the A/D conversion data will be output to the following words
m+1 to m+4.
Startup Operation
After the power is turned ON, it will require two cycle times plus approximately
50 ms before the first conversion data is stored in the input words. Therefore,
create a program as shown below, so that when operation begins simultaneously with startup it will wait for valid conversion data.
The analog input data will be 0000 until the initial processing is completed.

Handling Unit Errors
• When an error occurs in an Analog Input Unit, the analog input conversion
data becomes 0000.

Each CP1W-DA041/CPM1A-DA041 Analog Output Unit provides four analog
outputs.
• The analog output signal ranges are 1 to 5 V, 0 to 10 V, -10 to +10 V, 0 to
20 mA, and 4 to 20 mA. The resolution is 1/6,000. The open-circuit detection function is activated in the ranges of 1 to 5 V and 4 to 20 mA.
• The Analog Input Unit uses four output words, so a maximum of three
Units can be connected.

1 to 5 V and 4 to 20 mA ranges.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.

Writing Analog Output Set
Values
The ladder program can be used to write data to the output word where the
set value is stored. The output word will be “n+1” when “n” is the last output
word allocated to the CPU Unit, or previous Expansion Unit or Expansion I/O
Unit.
Startup Operation
After power is turned ON, it will require two cycle times plus approximately 50
ms before the first data is converted.
The following table shows the output status after the initial processing is completed.

Handling Unit Errors
• When an error occurs at the Analog Output Unit, the analog output will be
0 V or 0 mA. If a CPU Unit fatal error occurs when analog outputs are set
in the 1 to 5 V or 4 to 20 mA range, 0 V or 0 mA will be output for a CPU
error I/O bus error, and 1 V or 1 mA will be output for all other errors.
• Expansion Unit errors are output to bits 0 to 6 of word A436. The bits are
allocated from A436.00 in order starting with the Unit nearest the CPU
Unit. Use these flags in the program when it is necessary to detect errors.

Writing the Range Code
Write the range code to word n+1. A/D or D/A conversion begins when the
range code is transferred from the CPU Unit to the Analog I/O Unit. There are
eight range codes, FF00 to FF07, that combine both the analog input 1 and 2
and analog output signal ranges, as shown below.

• The Analog I/O Unit will not start converting analog I/O values until the
range code has been written.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
• If a range code other than those specified in the above table is written to
n+1, the range code will not be received by the Analog I/O Unit and analog I/O conversion will not start.

• Output range of 0 to 10 V/4 to 20 mA: Bits 08 to 15
Startup Operation
After power is turned ON, it will require two cycle times plus approx. 100 ms
before the first data is converted. The following instructions can be placed at
the beginning of the program to delay reading converted data from analog
inputs until conversion is actually possible.
Analog input data will be 0000 until initial processing has been completed.
Analog output data will be 0 V or 0 mA until the range code has been written.
After the range code has been written, the analog output data will be 0 V or
4 mA if the range is 0 to 10 V, −10 to 10 V, or 4 to 20 mA.

Averaging Function for
Analog Inputs
The averaging function can be enabled for inputs using the DIP switch. The
averaging function stores the average (a moving average) of the last eight
input values as the converted value. Use this function to smooth inputs that
vary at a short interval.
Open-circuit Detection
Function for Analog
Inputs
The open-circuit detection function is activated when the input range is set to
1 to 5 V and the voltage drops below 0.8 V, or when the input range is set to 4
to 20 mA and the current drops below 3.2 mA. When the open-circuit detection function is activated, the converted data will be set to 8,000.
The time for enabling or clearing the open-circuit detection function is the
same as the time for converting the data. If the input returns to the convertible
range, the open-circuit detection is cleared automatically and the output
returns to the normal range.

(1) Use shielded twisted-pair cables, but do not connect the shield.
(2) When an input is not being used, short the + and − terminals.
(3) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(4) When there is noise in the power supply line, install a noise filter on the
input section and the power supply terminals.

24 VDC
Example: If analog input device 2 is outputting 5 V and the same power supply is being used for both devices as shown above, approximately 1/3, or 1.6
V, will be applied to the input for input device 1.
If a wiring disconnection occurs when voltage input is being used, the situation described below will result. Either separate the power supplies for the
connected devices, or use an isolator for each input.
If the same power supply is being used by the connected devices and a disconnection occurs at points A or B in the above diagram, an unwanted circuit
path will occur as shown along the dotted line in the diagram. If that occurs, a
voltage of approximately 1/3 to 1/2 of the output voltage of the other connected device will be generated. If that voltage is generated while the setting
is for 1 to 5 V, open-circuit detection may not be possible. Also, if a disconnection occurs at point C in the diagram, the negative (-) side will be used in for
both devices and open-circuit detection will not be possible.
This problem will not occur for current inputs even if the same power supply is
used.
Note
When external power is supplied (when setting the range code), or when
there is a power interruption, pulse-form analog output of up to 1 ms may be
generated. If this causes problems with operation, take countermeasures
such as those suggested below.
• Turn ON the power supply for the CP1L CPU Unit first, and then turn ON
the power supply for the load after confirming correct operation.
• Turn OFF the power supply for the load before turning OFF the power
supply for the CP1L CPU Unit.

• The Analog I/O Unit will not start converting analog I/O values until the
range code has been written. Until conversion starts, inputs will be 0000,
and 0 V or 0 mA will be output.
• After the range code has been set, 0 V or 0 mA will be output for the 0 to
10-V, −10 to 10-V, or 0 to 20-mA ranges, and 1 V or 4 mA will be output for
the 1 to 5-V and 4 to 20-mA ranges until a convertible value has been
written to the output word.
• Once the range code has been set, it is not possible to change the setting
while power is being supplied to the CPU Unit. To change the I/O range,
turn the CPU Unit OFF then ON again.
459
Section 7-4
Analog I/O Units
Reading Converted Analog Input Values
The ladder program can be used to read the memory area words where the
converted values are stored. Values are output to the next two words (m + 1,
m + 2) following the last input word (m) allocated to the CPU Unit or previous
Expansion Unit or Expansion I/O Unit.
Writing Analog Output Set Values
The ladder program can be used to write data to the memory area where the
set value is stored. The output word will be “n+1,” where “n” is the last output
word allocated to the CPU Unit or previous Expansion Unit or Expansion I/O
Unit.
Startup Operation
After power is turned ON, it will require two cycle times plus approx. 50 ms
before the first data is converted. The following instructions can be placed at
the beginning of the program to delay reading converted data from analog
inputs until conversion is actually possible.
Analog input data will be 0000 until initial processing has been completed.
Analog output data will be 0 V or 0 mA until the range code has been written.
After the range code has been written, the analog output data will be 0 V or
0 mA if the range is 0 to 10 V, −10 to 10 V, or 0 to 20 mA, or it will be 1 V or
4 mA if the range is 1 to 5 V or 4 to 20 mA.

TIM 5 will start as soon as power turns ON.
After 0.1 to 0.2 s (100 to 200 ms), the input
for TIM 5 will turn ON, and the converted
data from analog input 0 that is stored in
word 2 will be transferred to D00000.

Handling Unit Errors
• When an error occurs in the Analog I/O Unit, analog input data will be
0000 and 0 V or 0 mA will be output as the analog output.
If a CPU error or an I/O bus error (fatal errors) occurs at the CPU Unit and
the analog output is set to 1 to 5 V or 4 to 20 mA, 0 V or 0 mA will be output. For any other fatal errors at the CPU Unit, 1 V or 4 mA will be output.
• Expansion Unit and Expansion I/O Unit errors are output to bits 0 to 6 of
word A436. The bits are allocated from A436.00 in order starting from the
Unit nearest the CPU Unit. Use these flags in the program when it is necessary to detect errors.
Programming Example
This programming example uses these ranges:
Analog input 0: 0 to 10 V
Analog input 1: 4 to 20 mA
Analog output: 0 to 10 V

Temperature input 3
When using a Temperature Sensor Unit with a thermocouple input, observe
the following precautions:
• Do not remove the cold junction compensator attached at the time of
delivery. If the cold junction compensator is removed, the Unit will not be
able to measure temperatures correctly.
• Each of the input circuits is calibrated with the cold junction compensator
attached to the Unit. If the Unit is used with the cold junction compensator
from other Units, the Unit will not be able to measure temperatures correctly.
• Do not touch the cold junction compensator. Doing so may result in incorrect temperature measurement.

Word Allocations
Temperature Sensor Units are allocated words as Expansion Units, in order of
connection. A Temperature Sensor Unit is allocated the next input words following the input words of the CPU Unit or previous Expansion Unit or Expansion I/O Unit. Four input words are allocated is to the 2-input CPM1A-TS001
or CPM1A-TS101 and four input words are allocated to the 4-input CPM1ATS002 or CPM1A-TS102. No output words are allocated.

”m” is the last input word allocated to the CPU Unit, Expansion I/O Unit, or
Expansion Unit connected immediately before the Temperature Sensor Unit.
• Negative values are stored as 2’s complements.
• Data for range codes that include one digit after the decimal point are
stored without the decimal point, i.e., 10 times the actual value is stored.

• If the input temperature exceeds the range that can be converted, the
converted temperature data will be held at the maximum or minimum
value in the range.
• If the input temperature exceeds the range by more than a specified
amount, the open-circuit detection function will detect an open-circuit and
the converted temperature data will be set to 7FFF.
The open-circuit detection function will also operate if the cold junction
compensator is faulty.
• The open-circuit detection function will be automatically cleared and normal input temperature conversion will begin automatically when the input
temperature returns to the convertible range.

Startup Operation
After power is turned ON, approximately 1 s is required for the first conversion
data to be stored in the input word. During that period, the data will be 7FFE.
Therefore, create a program as shown below, so that when operation begins
simultaneously with startup it will wait for valid conversion data.

Handling Unit Errors
• Expansion Unit and Expansion I/O Unit errors are output to bits 0 to 6 of
word A436. The bits are allocated from A436.00 in order starting from the
Unit nearest the CPU Unit. CP1W-/CPM1A-TS002 and CP1W-/CPM1ATS102 Temperature Sensor Units are allocated two bits each. Use these
flags in the program when it is necessary to detect Expansion Unit/Expansion I/O Unit errors.
• When an error occurs, the Temperature Sensor Unit data becomes 7FFF
hex (the same as for an open-circuit detection). With an open-circuit
detection, it is not reflected in word A436.

Two-decimal-place
Mode
Note
If pin 2 on the DIP switch is turned ON, values are stored to two decimal
places. In this case, temperature data is stored as 6-digit signed hexadecimal
(binary) data with 4 digits in the integer portion and 2 digits after the decimal
point. The actual data stored in memory is 100 times the actual value, i.e., the
decimal point is not indicated. Methods for handling this data are described in
this section.
When set to store values to two decimal places, temperature data as far as
two digits after the decimal point is converted to 6-digit binary data, but the
actual resolution is not 0.01°C (°F). For this reason, there may be skipping
and inaccuracies in the first digit after the decimal point (0.1). Treat any resolution above that specified for the normal data format as reference data.

allocated to the CompoBus/S I/O Link Unit are identical to input and output
bits allocated to Expansion I/O Units even though the CompoBus/S I/O Link
Unit does not control actual inputs and outputs. The input and output bits allocated to the CompoBus/S I/O Link Unit are one side of an I/O link between the

of data transmitted from the Slave CPU Unit at the same time will not always reach the Master CPU Unit simultaneously.
When the 8 bits of input data must be read together, modify the ladder
program in the CPU Unit receiving the data. For example, read the input
data twice in succession and accept the data only when the two values
match.
(2) Unused bits in the CompoBus/S I/O Link Unit’s output word can be used
as work bits, but unused bits in the output slaves cannot be used as work
bits.
(3) Unused bits in input word cannot be used as work bits.
Determining the Node
Number and Making DIP
Switch Settings
Node Number
• The CompoBus/S I/O Link Unit is a Slave Unit with 8 input bits and 8 output bits. The node number setting is made using the DIP switch; the
inputs and outputs share the same node number.
• The range of possible node number settings is determined by the type of
PLC the Master Unit is mounted to and the settings on the Master Unit.
For details refer to the CompoBus/S Operation Manual.

Trial Operation and Debugging
Forced Set/Reset
The CX-Programmer can force-set (ON) or reset (OFF) specified bits in the
CIO Area, Auxiliary Area, and HR Area, as well as timer/counter Completion
Flags. Forced status will take priority over status output from the program or
I/O refreshing. This status cannot be overwritten by instructions, and will be
stored regardless of the status of the program or external inputs until it is
cleared from the CX-Programmer.
Force-set/reset operations are used to force input and output during a trial
operation or to force certain conditions during debugging.
Force-set/reset operations can be executed in either MONITOR or PROGRAM modes, but not in RUN mode.
Note Turn ON the Forced Status Hold Bit (A500.13) and the IOM Hold Bit (A500.12)
at the same time to retain the status of bits that have been force-set or reset
when switching the operating mode.

Online Editing
The Online Editing function is used to add to or change part of a program in a
CPU Unit directly from the CX-Programmer when the CPU Unit is in MONITOR or PROGRAM mode. This function is designed for minor program
changes without stopping the CPU Unit.
Online editing is possible simultaneously from more than one computer running the CX-Programmer as long as different tasks are edited.

Program section changed
Operating in
MONITOR mode.
The cycle time will be increased by from one to several cycle times if the program in the CPU Unit is edited online in MONITOR mode. The cycle time will
also be increased to back up data in the flash memory after online editing.
The BKUP indicator will be lit during this period and the progress of the
backup will be displayed on the CX-Programmer. The increases per cycle are
listed in the following table.
CPU Unit
CP1L CPU Units
Increase in cycle time
Online editing
16 ms max.
Backup to flash memory
4% of cycle time
There is a limit to the number of edits that can be made consecutively. The
actual number depends on the type of editing that is performed, but 40 edits
should be used as a guideline. A message will be displayed on the CX-Programmer if the limit is exceeded, and further editing will not be possible until
the CPU Unit has completed backing up the data.
The length of time that the cycle time is extended due to online editing is
almost unaffected by the size of the task program being edited.
Precautions
The cycle time will be longer than normal when a program is overwritten using
Online Editing in MONITOR mode, so make sure that the amount of time that
it is extended will not exceed the cycle monitoring time set in the PLC Setup. If
it does exceed the monitoring time, then a Cycle Time Over error will occur,
and the CPU Unit will stop. Restart the CPU Unit by selecting PROGRAM
mode first before changing to RUN or MONITOR mode.
Note If the task being edited online contains a block program, then previous execution information, such as Standby (WAIT) or Pause status, will be cleared by
online editing, and the next execution will be from the beginning.

The instructions in the CPU Unit will be overwritten and cycle time will be
increased at this time.
!Caution Proceed with Online Editing only after verifying that the extended cycle time
will not adversely affect operation. Input signals may not be read if the cycle
time is too long.
Temporarily Disabling Online Editing
It is possible to disable online editing for specific cycles to ensure response
characteristics for machine control in those cycles. Online editing from the
CX-Programmer will be disabled for those cycles and any requests for online
editing received during those cycles will be held online editing is enables.
Online editing is disabled by setting the Online Editing Disable Bit Validator
(A527.00 to A527.07) to 5A and then turning ON the Online Editing Disable
Bit (A527.09). When these settings have been made and a request for online
editing is received, online editing will be put on standby and the Online Editing
Wait Flag (A201.10) will be turned ON.
When the Online Editing Disable Bit (A527.09) is turned OFF, online editing
will be performed, the Online Editing Processing Flag (A201.11) will turn ON,
and the Online Editing Wait Flag (A201.10) will turn OFF. When online editing
has been completed, the Online Editing Processing Flag (A201.11) will turn
OFF.
Online editing can also be temporarily disabled by turning ON the Online Editing Disable Bit (A527.09) while online editing is being performed. Here too,
the Online Editing Wait Flag (A201.10) will turn ON.
If a second request for online editing is received while the first request is on
standby, the second request will not be recorded and an error will occur.
Online editing can also be disabled to prevent accidental online editing. As
described above, disable online editing by setting the Online Editing Disable
Bit Validator (A527.00 to A527.07) to 5A and turning ON the Online Editing
Disable Bit (A527.09).
Enabling Online Editing from the CX-Programmer
When online editing cannot be enabled from the program, it can be enabled
from the CX-Programmer. If operations continue with online editing in standby
status, CX-Programmer may go offline. If this occurs, reconnect the computer
to the CPU Unit and turn OFF the Online Edit Disable Bit (A527.09).
Note When using automatic transfer from a Memory Cassette at startup, be sure to
transfer the data to the Memory Cassette if any changes are made using
online editing. If power is turned OFF before the changes are transferred, the
data from before online editing was performed will be read from the Memory
Cassette.

Tracing Data
The Data Trace function samples specified I/O memory data using any one of
the following timing methods. It stores the sampled data in Trace Memory,
where they can be read and checked later from the CX-Programmer.
• Specified sampling time (10 to 2,550 ms in 10-ms units)
• One sample per cycle
• When the TRACE MEMORY SAMPLING instruction (TRSM(045)) is executed
Up to 31 bits and 6 words in I/O memory can be specified for sampling.
Basic Procedure
1,2,3...
1. Sampling will start when the parameters have been set from the CX-Programmer and the command to start tracing has been executed.
2. Sampled data (after step 1 above) will be traced when the trace trigger
condition is met, and the data just after the delay (see note 1) will be stored
in Trace Memory.
3. Memory data will be sampled until the Trace Memory is full, and then the
trace will be ended.
Note Delay value: Specifies how many sampling periods to offset the sampling in
Trace Memory from when the trace condition is met. The setting ranges are
shown in the following table.
No. of words
sampled
Setting range
0
–1999 to 2000

2
–1332 to 1333
–999 to 1000
3
4
–799 to 800
–665 to 666
5
6
–570 to 571
–499 to 500
Positive delay: Store data delayed by the set delay.
Negative delay: Store previous data according go to the set delay.
Example: Sampling at 10 ms with a –30 ms delay time yields –30 x 10 =
300 ms, so data 300 ms before the trigger will be stored.

A scheduled data trace will sample data at fixed intervals. Specified sampling
interval is 10 to 2,550 ms in 10-ms units. Do not use the TRSM(045) instruction in the user program and be sure to set the sampling period higher than 0.
One-cycle Data Trace
A one-cycle data trace will sample I/O refresh data after the end of all cyclic
tasks. Do not use the TRSM(045) instruction in the user program and be sure
to set the sampling period higher than 0.
Data Trace via TRSM(045)
A sample will be taken once each time the TRACE MEMORY SAMPLING
instruction (TRSM(045)) instruction is executed. When more than one
TRSM(045) instruction is used in the program, a sample will be taken each
time TRSM(045) is executed after the trace trigger condition has been met
until trace memory is full.
Data Trace Procedure
Use the following procedure to execute tracing.
1,2,3...
1. Use the CX-Programmer to set trace parameters (select PLC - Data Trace
and then select Operation - Configure):
Addresses of the sampled words/bits, sampling period, delay time, and
trigger conditions.
2. Use the CX-Programmer to start sampling or turn ON the Sampling Start
Bit (A508.15).
3. Put the trace trigger condition into effect.
4. End tracing.
5. Use CX-Programmer to read the trace data.
a) Select Data Trace from the PLC Menu.
b) Select Select from the Operation Menu.
c) Select Execute from the Operation Menu.
d) Select Read from the Operation Menu.

will be stored in Trace Memory when the trigger condition is met. The following
traces are enabled with this bit.
1) Scheduled trace (trace at fixed intervals of 10 to 2,550 ms)
2) TRSM(045) instruction trace (trace when the TRSM(045) is executed)
3) One-cycle trace (trace at the end of execution of all cyclic tasks)
Trace Trigger Monitor Flag A508.11
This flag turns ON when the trace trigger condition has been met after the Trace
Start Bit has turned ON. This flag will turn OFF when the sampling is started.
Trace Busy Flag
A508.13
Trace Completed Flag
A508.12
This flag turns ON when sampling is started and turns OFF when the trace has
been completed.
This flag turns ON when Trace Memory becomes full after the trace trigger condition has been met during a trace operation and turns OFF when the next sampling operation is started.

10-2 Troubleshooting
Use the following procedure to check error details and remove the cause of
the error if the CPU Unit does not operate when the power supply is ON, operation suddenly stops and the error indicator (ERR/ALM indicator) lights, or if
the error indicator (ERR/ALM indicator) flashes during operating.
10-2-1 Error Processing Flowchart
Confirm the error category by referring to the status of the CPU Unit indicators, investigate the cause for the error in the error tables, and take corrective
actions.

10-2-2 No Operation When Power Is Supplied
First confirm that the POWER indicator (green) is lit.
POWER Indicator Not Lit
The power supply may not match the Unit rating, wiring may not be correct, or
the Unit may be faulty.
1,2,3...
1. Confirm the Unit rating (i.e., is it 24 VDC or 100 to 240 VAC?) and see if
the supply power matches the rating.
2. Check the wiring to see if it is correct and that nothing is disconnected.
3. Check the voltage at the power supply terminals. If the voltage is normal
and the POWER indicator is lit, the Unit may be faulty. In that case, replace
the Unit.
POWER Indicator Turns OFF and ON
There may be fluctuations in the power supply voltage, disconnected wiring,
or poor contacts. Check the power supply system and wiring.
POWER Indicator Lit but No Operation
Check the RUN indicator if the POWER indicator is lit but the CPU Unit does
not operate. The CPU Unit may be on standby if the RUN indicator is not lit.

If the PLC Setup has been set to stop operation for an
instruction error, the Error Flag will be turned ON when an
instruction cannot be executed due to a problem in the
operand data.
Indirect DM Addressing BCD Error
If the PLC Setup has been set to stop operation for an indirect DM BCD error, the Access Error Flag will turn ON when
the content of an indirectly addressed DM operand is not
BCD although BCD mode has been selected.
Possible remedy
Refer to A298 and A299 (instruction program address when
the program fails), check the specifications for the relevant
instruction, and set the correct operand data.
Alternatively, set the PLC Setup to not stop operation for an
instruction error.
Refer to A298 and A299 (instruction program address when
the program fails), and correctly set the content for the indirectly addressed DM operand (BCD mode) to BCD or
change the specified destination.
Alternatively, change the indirect addressing to binary
mode or set the PLC Setup to not stop operation for an indirect DM addressing BCD error.

Section 10-2
Troubleshooting
Probable cause
Illegal Area Access Error
If the PLC Setup has been set to stop operation for an illegal access error, the Access Error Flag will turn ON when
an illegal access error has occurred.
The following operations are considered illegal access:
• Reading/writing the parameter area
• Writing to an area without memory installed
• Writing to a write-protected area
• Indirect DM addressing BCD error
No END Error
This error occurs when there is not an END(001) instruction
in the program within a task.
Task Error
This error is generated by any of the following conditions.
1. There is not an executable cyclic task (active).
2. There is no specified interrupt task when an interrupt is
generated (input interrupt, high-speed counter interrupt,
scheduled interrupt, or external interrupt).
Possible remedy
Refer to A298 and A299 (instruction program address when
the program fails) and take corrective actions so that illegal
area access errors will not occur. Alternatively, set the PLC
Setup so that PLC operation will not stop when an instruction error occurs.
Differentiation Overflow Error
Differentiation instructions were repeatedly inserted or
deleted using the online editor and the system restriction
was exceeded.
Illegal Instruction Error
Execution of an unexecutable instruction was attempted.
For a CPU Unit with 10, 14 or 20 I/O Points, the instruction
operand will be given in D10000 to D31999.
Change the operating mode to PROGRAM mode and then
return to MONITOR mode.
UM Overflow Error
An attempt was made to execute a program that exceeds
the user program capacity.
Transfer the program again using the CX-Programmer.
Insert an END(001) instruction at the end of the program
allocated to the task stored in A294 (task number when the
program fails).
1. Check the properties of the executable cyclic task and set
at least one task to start when operation starts.
2. Create a task for the number stored in A294 (task number
when the program fails).
Check the program, correct the problem, and transfer the
program to the CPU Unit again.

Error Log
10-3 Error Log
Each time an error occurs, the CPU Unit stores error information in the Error
Log Area of the Auxiliary Area (A100 to A199). The error information includes
the error code (stored in A400), error contents, and time that the error
occurred. Up to 20 records can be stored in the Error Log.
In addition to system-generated errors, the CPU Unit records user-defined
errors, making it easier to track the operating status of the system.
When more than 20 errors occur, the oldest error data (stored in A100 to
A104) is deleted, the 19 errors stored in A105 to A199 shift one record, and
the newest record is stored in A195 to A199.
The number of records stored in the error log is stored in the Error Log Pointer
(A300). The Error Log Pointer is not incremented after 20 records have been
stored.

Inspections
11-1 Inspections
Daily or periodic inspections are required in order to maintain the PLC’s functions in peak operating condition.
11-1-1 Inspection Points
Although the major components in CP-series PLCs have an extremely long
life time, they can deteriorate under improper environmental conditions. Periodic inspections are thus required to ensure that the required conditions are
being kept.
Inspection is recommended at least once every six months to a year, but more
frequent inspections will be necessary in adverse environments.
Take immediate steps to correct the situation if any of the conditions in the following table are not met.

11-1-2 Unit Replacement Precautions
Check the following when replacing any faulty Unit.
• Do not replace a Unit until the power is turned OFF.
• Check the new Unit to make sure that there are no errors.
• If a faulty Unit is being returned for repair, describe the problem in as
much detail as possible, enclose this description with the Unit, and return
the Unit to your OMRON representative.
• For poor contact, take a clean cotton cloth, soak the cloth in industrial
alcohol, and carefully wipe the contacts clean. Be sure to remove any lint
prior to remounting the Unit.
Note When replacing a CPU Unit, be sure that not only the user program but also
all other data required for operation is transferred to or set in the new CPU
Unit before starting operation, including DM Area and HR Area settings. If

Replacing User-serviceable Parts
data area and other data are not correct for the user program, unexpected
accidents may occur.
11-2 Replacing User-serviceable Parts
The following parts should be replaced periodically as preventative maintenance. The procedures for replacing these parts are described later in this
section.
• Battery (backup for the CPU Unit’s internal clock and RAM)
Battery Functions
The battery maintains the internal clock and the following data of the CPU
Unit’s RAM while the main power supply is OFF.
• Retained regions of I/O memory (such as the Holding Area and DM Area)
If the battery is not installed or battery voltage drops too low, the internal clock
will stop and the data in RAM will be lost when the main power supply goes
OFF.
Battery Service Life and
Replacement Period
At 25°C, the maximum service life for batteries is five years whether or not
power is supplied to the CPU Unit while the battery is installed. The battery’s
lifetime will be shorter when it is used at higher temperatures.
The following table shows the approximate minimum lifetimes and typical lifetimes for the backup battery (total time with power not supplied).

Low Battery Indications
The ERR/ALM indicator on the front of the CPU Unit will flash when the battery is nearly discharged.
ERR/ALM indicator
When the ERR/ALM indicator flashes, connect the CX-Programmer to the
peripheral port and read the error messages. If a low battery message
appears on the CX-Programmer (see note 1) and the Battery Error Flag
(A402.04) is ON (see note 1), first check whether the battery is properly connected to the CPU Unit. If the battery is properly connected, replace the battery as soon as possible.
Once a low-battery error has been detected, it will take 5 days before the battery fails assuming that power has been supplied at lease once a day (see
note 2). Battery failure and the resulting loss of data in RAM can be delayed
by ensuring that the CPU Unit power is not turned OFF until the battery has
been replaced.
Note
1. The PLC Setup must be set to detect a low-battery error (Detect Low Battery). If this setting has not been made, the BATT LOW error message will
not appear on the CX-Programmer and the Battery Error Flag (A402.04)
will not go ON when the battery fails.
2. The battery will discharge faster at higher temperatures, e.g., 4 days at
40°C and 2 days at 55°C.
Replacement Battery
Use the CJ1W-BAT01 Battery Set. Be sure to install a replacement battery
within two years of the production date shown on the battery’s label.

Replacement Procedure
Note
Use the following procedure to replace the battery when the previous battery
has become completely discharged. You must complete this procedure within
five minutes after turning OFF the power to the CPU Unit to ensure memory
backup.
1. We recommend replacing the battery with the power OFF to prevent the
CPU Unit’s sensitive internal components from being damaged by static
electricity. The battery can be replaced without turning OFF the power supply. To do so, always touch a grounded piece of metal to discharge static
electricity from your body before starting the procedure.
2. After replacing the battery, connect the CX-Programmer and clear the battery error.
579
Replacing User-serviceable Parts
Section 11-2
Procedure
1,2,3...
1. Turn OFF the power to the CPU Unit.
or If the CPU Unit has not been ON, turn it ON for at least five minutes and
then turn it OFF.
Note If power is not turned ON for at least five minutes before replacing the
battery, the capacitor that backs up memory when the battery is removed will not be fully charged and memory may be lost before the
new battery is inserted.
2. Open the compartment on the CPU Unit and carefully draw out the battery.
3. Remove the battery connector.
4. Connect the new battery, place it into the compartment, and close the cover.

!WARNING Never short-circuit the battery terminals; never charge the battery; never disassemble the battery; and never heat or incinerate the battery. Doing any of
these may cause the battery to leak, burn, or rupturing resulting in injury, fire,
and possible loss of life or property. Also, never use a battery that has been
dropped on the floor or otherwise subject to shock. It may leak.
!Caution You must complete this procedure within five minutes after turning OFF the
power to the CPU Unit to ensure memory backup. If the procedure is not completed within 5 minutes, data may be lost.
!Caution UL standards require that batteries be replaced by experienced technicians.
Always place an experienced technician in charge or battery replacement.
580
Replacing User-serviceable Parts
Section 11-2
!Caution Turn ON the power after replacing the battery for a CPU Unit that has been
unused for a long time. Leaving the CPU Unit unused again without turning
ON the power even once after the battery is replaced may result in a shorter
battery life.
Note The battery error will automatically be cleared when a new battery is inserted.

Interrupt Counter
Counter SV
Used for an interrupt input in counter mode.
Read/Write
Sets the count value at which the interrupt task will start. The corresponding interrupt task will start when the interrupt counter has
counted this number of pulses.
• Retained when power is
turned ON.
• Retained when operation starts.
Interrupt Counter
Counter PV
These words contain the interrupt counter PVs for interrupt inputs
Read/Write
operating in counter mode.
In increment mode, the counter PV starts incrementing from 0.
When the counter PV reaches the counter SV, the PV is automatically reset to 0.
In decrement mode, the counter PV starts decrementing from the
counter SV. When the counter PV reaches the 0, the PV is automatically reset to the SV.
• Retained when power is
turned ON.
• Cleared when operation
starts.
• Updated when interrupt
is generated.
