• 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.
• Construct a control circuit so that power supply for the I/O circuits does not
come ON before power supply for the PC. If power supply for the I/O circuits
comes ON before power supply for the PC, normal operation may be temporarily interrupted.
• If the operating mode is changed from RUN or MONITOR mode to PROGRAM
mode, with the IOM Hold Bit ON, the output will hold the most recent status. In
such a case, ensure that the external load does not exceed specifications. (If
operation is stopped because of an operation error (including FALS instructions), the values in the internal memory of the CPU board will be saved, but
the outputs will all turn OFF.)
• 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 is supplied. Be particularly careful in places where the power supply is
unstable. An incorrect power supply may result in malfunction.
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting 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.
• Be sure that all the mounting screws, terminal screws, and cable connector
screws are tightened to the torque specified in the relevant manuals. Incorrect
tightening torque may result in malfunction.
• When wiring the CPM2B, take countermeasures to prevent wiring cuttings
from coming into contact with the product, such as covering the whole product
with a dustproof cover. If wiring cuttings adhere to the PCB or circuit elements
they may cause short-circuiting.
• Be sure to perform wiring in accordance with the relevant operation manual.
Incorrect wiring may result in burning.
• Double-check all the wiring before turning ON the power supply. Incorrect wiring may result in burning.
• Be sure that the terminal blocks, expansion cables, and other items with locking devices are properly locked into place. Improper locking may result in malfunction.
• Be sure that terminal blocks and connectors are connected in the specified direction with the correct polarity. Not doing so may result in malfunction.
• Check the user program for proper execution before actually running it on the
PC. Not checking the program may result in an unexpected operation.

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 Applicable EMC (Electromagnetic Compatibility) standards are as follows:
EMS (Electromagnetic Susceptibility): EN61131-2
EMI (Electromagnetic Interference):
EN50081-2
(Radiated emission: 10-m regulations)
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to
1,500 VDC meet the required safety standards for the PC (EN61131-2).

Conformance to EC Directives
The CPM2B PCs comply with EC Directives. To ensure that the machine or device in which the CPM2B PC is used complies with EC directives, the PC must be
installed as follows:
1, 2, 3...
6-4
1. The CPM2B PC must be installed within a control panel.
2. Reinforced insulation or double insulation must be used for the DC power
supplies used for the communications and I/O power supplies.
3. CPM2B PCs complying with EC Directives also conform to the Common
Emission Standard (EN50081-2). 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.
Relay Output Noise Reduction Methods
The CPM2B PCs conform to the Common Emission Standards (EN50081-2) of
the EMC Directives. However, the noise generated when the PC is switched ON
or OFF using the relay output 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 PC.
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
(Refer to EN50081-2 for more details.)
Countermeasures are not required if the frequency of load switching for the
whole system with the PC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system with the PC included is 5 times or more per minute.

Characteristic
Required element
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.
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.
DC
If the supply voltage is 24 to 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 dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is
an AC circuit, use a capacitor with no

The diode connected in parallel with
the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current
will be converted into Joule heat by
the resistance of the inductive load.
The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.
This time lag, between the moment
the circuit is opened and the moment
the load is reset, caused by this
method is longer than that caused by
the CR method.
The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.
The varistor method prevents the
--imposition of high voltage between the
contacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the
circuit is opened and the moment the
load is reset.
If the supply voltage is 24 to 48 V,
insert the varistor in parallel with the
load. If the supply voltage is 100 to
200 V, insert the varistor between the
contacts.

CPM2B Features and Functions
1-1-1 CPM2B Features
The CPM2B PCs are compact Board PCs that can be incorporated easily into
control equipment. The PCs are equipped with a variety of advanced features
including synchronized pulse control, interrupt inputs, high-speed counters,
pulse outputs, and a clock function.
• The compact Board design is ideal for incorporation into control equipment.
• The CPU Board itself can handle a wide range of machine control applications,
so it is ideal for use as a built-in control unit in control equipment.
• The CPM2B is equipped with a full complement of communications functions
to provide communications with personal computers, other OMRON PCs, and
OMRON Programmable Terminals. These communications capabilities allow
the user to design a low-cost distributed production system.
Peripheral Port
Programming Devices are compatible with other
models of OMRON PCs. This port can also be used
for Host Link or no-protocol communications.
RS-232C Port
This port can be used for a Host Link,
no-protocol, 1:1 PC Link, or 1:1 NT Link
communications.
Transistor Output Board
Relay Output Board
The CPU Board has 32 I/O points and Expansion
I/O Boards can be added to provide a total I/O capacity of up to 128 I/O points.
Basic Functions
CPU Board I/O
The CPM2B CPU Board itself is equipped with 32 I/O points in I/O terminals or
I/O connectors. There are 2 types of outputs available (relay outputs and sinking
transistor outputs). The power supply is 24 V DC only.
Expansion I/O Boards
Up to 3 Expansion I/O Boards can be connected to the CPU Board to increase
the PC’s I/O capacity to a maximum of 128 I/O points. There are 2 types of
32-point Expansion I/O Boards available: one with relay outputs and the other
with sinking transistor outputs.
Share Programming
Devices
The same Programming Devices, such as Programming Consoles and Support
Software, can be used for the C200H, C200HS, C200HX/HG/HE, CQM1,
CPM1, CPM1A, CPM2A, CPM2C, and SRM1 (-V2) PCs, so existing ladder program resources can be used effectively.
Built-in Motor Control Capability
Synchronized Pulse
Control
(Transistor Outputs Only)

Synchronized pulse control provides an easy way to synchronize the operation
of a peripheral piece of equipment with the main equipment. The output pulse
frequency can be controlled as some multiple of the input pulse frequency, al-

lowing the speed of a peripheral piece of equipment (such as a supply conveyor)
to be synchronized with the speed of the main piece of equipment.
Motor driver Motor
Encoder
CPM2B
Pulses are output as a fixed multiple of the input frequency.
High-speed Counters and
Interrupts
The CPM2B has a total of five high-speed counter inputs. The one high-speed
counter input has a response frequency of 20 kHz/5 kHz and the four interrupt
inputs in counter mode have a response frequency of 2 kHz.
The high-speed counter can be used in any one of the four input modes: differential phase mode (5 kHz), pulse plus direction input mode (20 kHz), up/down
pulse mode (20 kHz), or increment mode (20 kHz). Interrupts can be triggered
when the count matches a set value or falls within a specified range.
The interrupt inputs in counter mode can be used for incrementing counters or
decrementing counters (2 kHz) and trigger an interrupt (executing the interrupt
program) when the count matches the target value.
Easy Position Control
with Pulse Outputs
(Transistor Outputs Only)
CPM2B PCs with transistor outputs have two outputs that can produce 10 Hz to
10 kHz pulses (single-phase outputs).
When used as single-phase pulse outputs, there can be two outputs with a frequency range of 10 Hz to 10 kHz with a fixed duty ratio or 0.1 to 999.9 Hz with a
variable duty ratio (0 to 100% duty ratio).
When used as pulse plus direction or up/down pulse outputs, there can be just
one output with a frequency range of 10 Hz to 10 kHz.
High-speed Input Capabilities for Machine Control
High-speed Interrupt
Input Function
There are four inputs used for interrupt inputs (shared with quick-response inputs and interrupt inputs in counter mode) with a minimum input signal width of
50 µs and response time of 0.3 ms. When an interrupt input goes ON, the main
program is stopped and the interrupt program is executed.
Quick-response Input
Function
There are four inputs used for quick-response inputs (shared with interrupt inputs and interrupt inputs in counter mode) that can reliably read input signals
with a signal width as short as 50 µs.
Stabilizing Input Filter
Function
The input time constant for all inputs can be set to 1 ms, 2 ms, 3 ms, 5 ms,
10 ms, 20 ms, 40 ms, or 80 ms. The effects of chattering and external noise can
be reduced by increasing the input time constant.
Other Functions
Interval Timer Interrupts
The interval timer can be set between 0.5 and 319,968 ms and can be set to generate just one interrupt (one-shot mode) or periodic interrupts (scheduled interrupt mode).
Analog Settings
There are two controls on the CPU Board that can be turned to change the analog settings (0 to 200 BCD) in IR 250 and IR 251. These controls can be used to
easily change or fine-tune machine settings such as a conveyor belt’s pause
time or feed rate.
DIP Switch Inputs
A DIP switch is provided that controls the status of four input bits.
Calendar/Clock
The built-in clock (accuracy within 1 minute/month) can be read from the program to show the current year, month, day, day of the week, and time. The clock
can be set from a Programming Device (such as a Programming Console) or the
time can be adjusted by rounding up or down to the nearest minute.
Long-term Timer
TIML(––) is a long-term timer that accommodates set values up to 99,990 seconds (27 hours, 46 minutes, 30 seconds). When combined with the SECONDS
3
Section

TO HOURS conversion instruction (HMS(––)), the long-term timer provides an
easy way to control equipment scheduling.
Expansion Memory Unit
The CPM1-EMU01-V1 Expansion Memory Unit is a program loader for smallsize or micro PCs. Using the CPM1-EMU01-V1, simple on-site transfer of user
programs and data memory is possible with PCs.

Complete Communications Capabilities
Host Link
A Host Link connection can be made through the PC’s RS-232C port or Peripheral port. A personal computer or Programmable Terminal connected in Host
Link mode can be used for operations such as reading/writing data in the PC’s
I/O memory or reading/changing the PC’s operating mode.

Note
1. The NT-AL001-E must be supplied externally with 5 V DC. When an NTAL001-E is connected to a CPM2B PC, pin 6 of the CPM2B’s RS-232C port
supplies +5 V DC and an external power supply is not necessary. When the
NT-AL001-E is connected to a host computer, it is necessary to supply 5 V
DC from an external power supply.
If an NT-AL001-E is connected to the CPM2B’s RS-232C port, only one Expansion I/O Board can be connected to the CPU Board because the NTAL001-E draws its 5-V DC power from the CPU Board.
Use an XW2Z-070T-1 (0.7 m) or XW2Z-200T-1 (2 m) cable to connect the
NT-AL001-E to the CPM2B’s RS-232C port.
2. The 3G2A9-AL004-E requires an external AC power supply (110 V AC or
220 V AC).
3. The CPM1-CIF11 is supplied +5 V DC from the peripheral port so an external power supply is not necessary.

The program reads and writes data in this memory area during execution. Part of
the I/O memory contains the bits that reflect the status of the PC’s inputs and
outputs. Parts of the I/O memory are cleared when the power is turned ON and
other parts are retained.
Note Refer to Section 4 Memory Areas for more details on I/O memory.
Program
This is the program written by the user. The CPM2B executes the program cyclically. (Refer to 1-3-5 Cyclic Operation and Interrupts for details.)
The program can be divided broadly into two parts: the “main program” that is
executed cyclically and the “interrupt programs” that are executed only when the
corresponding interrupt is generated.
PC Setup
The PC Setup contains various startup and operating parameters. The PC Setup parameters can be changed from a Programming Device only; they cannot
be changed from the program.
Some parameters are accessed only when PC’s power supply is turned on and
others are accessed regularly while the power is on. It will be necessary to turn
the power off and then on again to enable a new setting if the parameter is accessed only when the power is turned on.
Note Refer to 4-5 PC Setup for more details.
Communications
Switches
The Communications Switches determine whether the peripheral port and
RS-232C port operate with the standard communications settings or the communications settings in the PC Setup. Refer to 2-2 Board Components and their
Functions for more details.

1-3-2 Operating Modes
CPM2B CPU Boards have 3 operating modes: PROGRAM, MONITOR, and
RUN.
PROGRAM Mode
The program cannot be executed in PROGRAM mode. This mode is used to
perform the following operations in preparation for program execution
• Changing initial/operating parameters such as those in the PC Setup
• Writing, transferring, or checking the program
• Checking wiring by force-setting and force-resetting I/O bits
! Caution
The PC continues to refresh I/O bits even if the PC is in PROGRAM mode, so
devices connected to output points on the CPU Board or Expansion I/O Boards
may operate unexpectedly if the corresponding output bit is turned ON by
changing the contents of I/O memory from a Programming Device.
MONITOR Mode
The program is executed in MONITOR mode and the following operations can
be performed from a Programming Device. In general, MONITOR mode is used
to debug the program, test operation, and make adjustments.
• Online editing
• Monitoring I/O memory during operation
• Force-setting/force-resetting I/O bits, changing set values, and changing present values during operation
RUN Mode
The program is executed at normal speed in RUN mode. Operations such as
online editing, force-setting/force-resetting I/O bits, and changing set values/
present values cannot be performed in RUN mode, but the status of I/O bits can
be monitored.
1-3-3 Operating Mode at Startup
The operating mode of the CPM2B when the power is turned ON depends upon
the PC Setup settings and the Programming Console’s mode switch setting if a
Programming Console is connected.

2. The default setting of bits 08 to 15 of DM 6600 is 00. With this default setting,
the PC will automatically enter RUN mode if a Programming Console is not
connected and SW201 is ON. Be sure that it is safe for the PC to operate
before turning it ON under these conditions.

1-3-4 PC Operation at Startup
Time Required for
Initialization
The time required for startup initialization depends on several factors, such as
the operating conditions (including power supply voltage, system configuration,
and ambient temperature) and the program contents.
Power OFF Operation
Minimum Power Supply Voltage
The PC will stop and all outputs will be turned OFF if the power supply voltage
falls below 85% of the rated value.
Momentary Power Interruption
A power interruption will not be detected and CPU Board operation will continue
if the power interruption lasts less than 2 ms for a DC power supply.
A power interruption may or may not be detected for power interruptions somewhat longer than 2 ms for a DC power supply.
When a power interruption is detected, the CPU Board will stop operating and all
outputs will be turned OFF.
Automatic Reset
Operation will restart automatically when the power supply voltage is restored to
more than 85% of the rated voltage.
Timing Chart of Power OFF Operation
The power interruption detection time is the time required for a power interruption to be detected after the power supply voltage drops below 85% of the rated
value.

Note If the power supply voltage fluctuates around 85% of the PC’s rated voltage, PC
operation may stop and restart repeatedly. When repeated stopping and starting
will cause problems with the controlled system, set up a protective circuit such
as a circuit that shuts off the power supply to sensitive equipment until the power
supply voltage returns to the rated value.

initialization errors, the overseeing processes, program execution, I/O refreshing, and communications port servicing are performed repeatedly (cyclically).

S Calculate cycle time.
S Read input data from input bits.

The cycle time can be read from a Programming Device.
AR 14 contains the maximum cycle time and AR 15 contains the present cycle
time in 4-digit BCD.
16
Section
Structure and Operation
1-3
The cycle time will vary slightly depending on the processing being performed in
each cycle, so the calculated cycle time will not always match the actual cycle
time.
Program Execution in
Cyclic Operation
The following diagram shows the cyclic operation of the CPM2B when the program is being executed normally.
Normally, the results of program execution are transferred to I/O memory just
after program execution (during I/O refreshing), but IORF(97) can be used to refresh a specified range of I/O words during program execution. The specified
range of I/O words will be refreshed when IORF(97) is executed.
The cycle time is the sum of the time required for program execution, I/O refreshing, and communications port servicing.
A minimum cycle time (1 to 9,999 ms) can be set in the PC Setup (DM 6619).
When a minimum cycle time has been set, CPU operation is paused after program execution until the minimum cycle time is reached. CPU operation will not
be paused if the actual cycle time is longer than the minimum cycle time set in
DM 6619.
Note A fatal error will occur and PC operation will stop if a maximum cycle time has
been set in the PC Setup (DM 6618) and the actual cycle time exceeds that setting.
The default settings for RS-232C port servicing and Peripheral port servicing are
5% of the cycle time, but these settings can be changed (between 1% and 99%)
in the PC Setup. The RS-232C port’s setting is in DM 6616 and the Peripheral
port’s setting is in DM 6617.

Section
Structure and Operation
Interrupt Program
Execution
1-3
When an interrupt is generated during execution of the main program, main program execution is interrupted immediately and the interrupt program is executed. The following diagram shows the cyclic operation of the CPM2B when an
interrupt program is executed.
Normally, the results of interrupt program execution are transferred to I/O
memory just after program execution (during I/O refreshing), but IORF(97) can
be used to refresh a specified range of I/O words during execution of the interrupt program. The specified range of I/O words will be refreshed when IORF(97)
is executed.
The normal cycle time is extended by the time required for execution of the interrupt program.
Refer to Section 7 PC Operations and Processing Time in the CPM1/CPM1A/
CPM2A/CPM2C/SRM1(-V2) Programmable Controllers Programming Manual
(W353) for more details and precautions on the cycle time.

! Caution
Immediate Refreshing
Although IORF(97) can be used in interrupt subroutines, you must be careful of
the interval between IORF(97) executions. If IORF(97) is executed too frequently, a fatal system error may occur (FALS 9F), stopping operation. The interval
between executions of IORF(97) should be at least 1.3 ms + total execution time
of the interrupt subroutine.
IORF(97) can be executed in the program to refresh a specified range of I/O
words. The specified I/O words will be refreshed when IORF(97) is executed.
IORF(97) can be used to refresh I/O from the main program or the interrupt program.

1. The DM area, HR area, AR area, and counter values are backed up by the
CPU Board’s built-in battery or capacitor. If the battery or capacitor is discharged, the contents of these areas will be lost and the data values will revert to the defaults.
2. The contents of the program area, read-only DM area (DM 6144 to
DM 6599), and PC Setup (DM 6600 to DM 6655) are stored in flash
memory. The contents of these areas will be read from flash memory the
next time the power is turned ON, even if the backup battery or capacitor is
discharged.
When data has been changed in any of these areas, write the new values to
flash memory by switching the CPM2B to MONITOR or RUN mode, or by
turning the power OFF and then ON again.

Design Precautions
Observe the following precautions when designing a system incorporating a
CPM2B PC.
3-1-1 Power Supply Wiring
Separate the power supply wiring from the power system, control system,
CPM2B system, and DC I/O system wiring. Separate the control circuits that
supply power to the main Unit from the main circuits using dedicated circuit protectors and fuses.
3-1-2 Power Supply Voltage
! Caution
Use the power supply voltages indicated in Section 2-1 Specification. Failure to
adhere to the specifications may result in fire.
If the power supply voltage falls below 85% of the rated voltage, the CPM2B will
stop and all outputs will be turned OFF. If low voltage affects the equipment, etc.,
provide a protection circuit which shuts off the output until the supply voltage returns to the rated value.
In places where power supply conditions are poor, take steps to ensure that
power is supplied at the rated voltage. Be sure to adhere to safety precautions,
such as providing breakers to prevent short circuits in external wiring.
When conducting any of the following operations, turn OFF the power to the PC.
Electrocution, product damage and malfunction may result.
• Connecting or disconnecting Expansion I/O Boards and CPU Boards.
• Assembling equipment.
• Connecting cables and wiring.
3-1-3 Interlock and Limit Circuits
! WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits (i.e., not in the
Programmable Controller) to ensure safety in the system if an abnormality
occurs due to malfunction of the PC or another external factor affecting the PC
operation. Not providing proper safety measures may result in serious
accidents.
The following diagram shows an example of an interlock circuit.

A leakage current can cause false inputs when using 2-wire sensors (proximity
switches or photoelectric switches) or limit switches with LEDs. False inputs
won’t occur if the leakage current is less than 1.0 mA (2.5 mA for IN00000 to
IN00002). If the leakage current exceeds these values, insert a bleeder resistor
in the circuit to reduce the input impedance, as shown in the following diagram.

Using Pulse Outputs
Use the PULS(65), SPED(––), ACC(––), PWM(––), and SYNC(––) instructions
to produce pulse outputs (rather than normal outputs) from output bits IR 01000

Precautions
Observe the following precautions to protect the PC’s internal components.
Output Short Protection
The output or internal circuitry might be damaged when the load connected to an
output is short-circuited, so it is recommended to install a protective fuse in each
output circuit.
Inductive Loads
When connecting an inductive load to an input, connect a surge protector or
diode in parallel with the load.
The surge protector’s components should have the following ratings:

The diode should satisfy the following requirements:
Peak reverse-breakdown voltage must be at least 3 times the load voltage.
Average rectified current must be 1 A.
Inrush Current Considerations
When a relay or transistor output is used to switch a load with a high inrush current such as an incandescent lamp, suppress the inrush current as shown
below.

Function
These bits can be allocated to the external
I/O terminals.
Work bits can be freely used within the
program.
These bits serve specific functions such as
flags and control bits.
These bits are used to temporarily store
ON/OFF status at program branches.
These bits store data and retain their
ON/OFF status when power is turned off.
These bits serve specific functions such as
flags and control bits.
Used for a 1:1 data link with another PC.
The same numbers are used for both
timers and counters.
DM area data can be accessed in word
units only. Word values are retained when
the power is turned off.
The read-only area and PC Setup cannot
be overwritten from program. Change
these settings with a Programming Device.
1. Input bits IR 00108 to IR 00111 reflect the status of the DIP switch on the
CPU Board.
2. The contents of the HR area, AR area, Counter area, and read/write DM
area are backed up by the CPU Board’s backup battery or capacitor. If the
battery or capacitor discharges completely, memory contents will be returned to their default settings.
3. The program and data in DM 6144 to DM 6655 are stored in flash memory.
4-1-1 Functions
IR Area
54
The functions of the IR area are explained below.
IR area bits in the input and output areas are allocated to terminals on the CPU
Board and Expansion I/O Boards. They reflect the ON/OFF status of input and
output signals. Input bits begin at IR 00000, and output bits begin at IR 01000.
Section
I/O Allocation
4-2
IR words that are not allocated to inputs or outputs can be used as work words.
Work Bits
The work bits can be used freely within the program. They can only be used within the program, however, and not for direct external I/O.
SR Area
These bits mainly serve as flags for CPM2B operation or contain present and set
values for various functions. SR 253 to SR 255 are read-only. Refer to 4-3 SR
Area for details on the various bit functions.
TR Area
When a complex ladder diagram cannot be programmed in mnemonic code just
as it is, these bits are used to temporarily store ON/OFF execution conditions at
program branches. They are used only for mnemonic code. When programming
directly with ladder diagrams using the Support Software, TR bits are automatically processed for you.
The same TR bits cannot be used more than once within the same instruction
block, but can be used again in different instruction blocks. The ON/OFF status
of TR bits cannot be monitored from a Programming Device.
HR Area
These bits retain their ON/OFF status even after the PC power supply has been
turned off or when operation begins or stops. They are used in the same way as
work bits.
AR Area
These bits mainly serve as flags related to PC operation. These bits retain their
status even after the PC power supply has been turned off or when operation
begins or stops. Refer to 4-4 AR Area for details on the various bit functions.
LR Area
When the CPM2B is linked 1:1 with another CPM2B or a CPM1/CPM1A/
CPM2A/CPM2C/SRM1(-V2), a CQM1, a C200HS or a C200HX/HG/HE PC,
these bits are used to share data.
LR words can be used as work words when they are not used for a 1:1 PC Link.
Timer/Counter Area
This area is used to manage timers and counters created with TIM, TIMH(15),
TMHH(––), TIML(––), CNT, and CNTR(12). The same numbers are used for
both timers and counters and each number can be used only once in the user
program. Do not use the same TC number twice even for different instructions.
Use TC numbers 000 to 003 for TIMH(15) and TC numbers 004 to 007 for
TMHH(––). When these timer numbers are used, timing is performed as an interrupt process and the cycle time is not affected.
TC numbers are used to create timers and counters, as well as to access
Completion Flags and present values (PVs). If a TC number is designated for
word data, it will access the present value (PV); if it is used for bit data, it will access the Completion Flag for the timer/counter.
DM Area
DM area data is accessed in word units only. The contents of the DM area are
retained even after the PC power supply has been turned off or when operation
begins or stops.
DM words DM 0000 to DM 1999 and DM 2022 to DM 2047 can be used freely in
the program; other DM words are allocated specific functions.
DM 2000 to DM 2021 contain the error log information. Refer to Section 4-6 Error
Log for details on the error log.
DM 6600 to DM 6655 contain the PC Setup. Refer to 4-5 PC Setup for details.

I/O Allocation
IR bits are allocated to actual input terminals and output terminals on the CPU
Board and Expansion I/O Boards. IR words that are not allocated to inputs or
outputs can be used as work words.

present and set values for various functions. The functions of the SR area are
explained in the following table.
Note “Read-only” words and bits can be read as status in controller PC operation, but
they cannot be written from the ladder program. Bits and words that are “Not
used” are also read-only.

turned OFF automatically when the new setting goes into effect.)
3. The units for the maximum and current cycle times are determined by the
setting in bits 08 to 15 of DM 6618. A setting of 00 specifies 0.1-ms units, 01
specifies 0.1-ms units, 02 specifies 1-ms units, and 03 specifies 10-ms
units.
PC Setup
The PC Setup comprises various operating parameters that control PC operation. In order to make the maximum use of PC functionality when using interrupt
processing and communications functions, the PC Setup may be customized
according to operating conditions.
After the PC Setup has been changed, be sure to switch the CPM2B to MONITOR or RUN mode or turn the power OFF and then ON again.
4-5-1 Changing the PC Setup
The PC Setup settings in DM 6600 to DM 6655 can be changed from a Programming Device. The CPM2B must be in PROGRAM mode in order to change the
settings in DM 6600 to DM 6644. The settings in DM 6645 to DM 6655 can be
changed in MONITOR or PROGRAM mode, but CPM2B’s cycle time will be long
if the settings are changed in MONITOR mode.
All of the PC Setup settings are set to their defaults when the CPM2B is shipped.
The default values for the PC Setup are 0000 for all words (except for the low
battery error enable in DM 6655 bits 12 to 15).
Effectiveness of Changes
PC Setup settings are accessed at various times depending on the setting, as
described below.

Errors in the PC Setup
If an incorrect PC Setup setting is accessed, a non-fatal error (error code 9B) will
be generated, the corresponding error flag (AR 1300 to AR 1302) will be turned
ON, and the default setting will be used instead of the incorrect setting.

Error Log
The error log function registers the error code of any fatal or non-fatal error that
occurs in the PC. The date and time at which the error occurred are registered
along with the error code. The error code is also stored in AR 253.
The error log is stored in DM 2000 through DM 2021. Up to 7 error records can be
stored.

2. In CPU Boards without a clock, the time that the error occurred will be set to
all zeroes.
Error Log Storage Methods
The error log storage method is set in the PC Setup (bits 00 to 03 of DM 6655).
Set any of the following methods.
1, 2, 3...
1. DM 6655 bits 00 to 03 set to 0:
Stores the most recent 7 error log records and discard older records. This is
achieved by shifting the records as shown below so that the oldest record
(record 0) is lost whenever a new record is generated.
Lost
Error log record 1
Error log record 2
All records shifted
Error log record 6
Error log record 7
New record added
2. DM 6655 bits 00 to 03 set to 1:
Stores only the first 7 error log records, and ignores any subsequent errors
beyond those 7.
3. DM 6655 bits 00 to 03 set to any value other than 0 or 1:
Disables the log so that no records are stored.
The default setting is the first method. Refer to the preceding page for details on
the error log settings in DM 6655.
Clearing the Error Log
To clear the entire error log, turn ON SR 25214 from a Programming Device. (After the error log has been cleared, SR 25214 will turn OFF again automatically.)

Expansion Instructions
A set of expansion instructions is provided to aid in special programming needs.
Function codes can be assigned to up to 18 of the expansion instructions to enable using them in programs. This allows the user to pick the instructions needed
by each program to more effectively use the function codes required to input
instructions.
The mnemonics of expansion instructions are followed by “(––)” as the function
code to indicate that they must be assigned function codes by the user in the
instructions table before they can be used in programming (unless they are used
under their default settings).
Refer to the 6-2-5 Assigning Expansion Instruction Function Codes for a description of the Programming Console operations used to change expansion instruction allocations.
Refer to the SYSMAC Support Software Operation Manuals: C-series PCs
(W248), the SYSMAC-CPT Support Software User Manual (W333), or the
WS02-CXPC1-E CX-Programmer User Manual (W361) for a description of the
corresponding Support Software operations.

Operating Modes
PROGRAM Mode
The CPM2B program isn’t executed in PROGRAM mode. Use PROGRAM
mode to create and edit the program, clear memory, or check the program for
errors, or check output wiring.
MONITOR Mode
The CPM2B program is executed in MONITOR mode and I/O is processed just
as it is in RUN mode. Use MONITOR mode to test system operations, such as
monitoring CPM2B operating status, force-setting and resetting I/O bits, changing the SV/PV of timers and counters, changing word data, and online editing.
RUN Mode
This is the CPM2B’s normal operating mode. The CPM2B’s operating status can
be monitored from a Programming Device, but bits can’t be force-set/force-reset
and the SV/PV of timers and counters can’t be changed.
80
! Caution
Check the system thoroughly before changing the operating mode of the PC to
prevent any accidents that might occur when the program is first started.
! Caution
Never change the mode while pressing any of the keys.

Initial System Checks and Test Run Procedure
7-1-1 Initial System Checks
Check the following items after setting up and wiring the CPM2B, but before performing a test run.
Item
Power supply and
I/O connections
Points to check
Is the wiring correct?
Are the terminals securely tightened?
Are there any shorts between crimp terminals or wires?
Refer to 3-5 Wiring and Connections for details.
Connecting cables
Are the cables all connected correctly and locked?
Refer to 3-5 Wiring and Connections for details.
Clearing Memory
Always clear memory before beginning to program the CPM2B. Although
memory is cleared before the CPU Board is shipped, the contents of the DM,
HR, AR, and counter areas may change in transit.
When a CPU Board without a clock is being used and the contents of DM have
been cleared, battery error detection must be disabled in the PC Setup by setting
the leftmost digit of DM 6655 to 1.
Operating Mode at
Startup
See 1-3-3 Operating Mode at Startup to determine what mode the CPM2B will
enter when the power is turned on.
7-1-2 Flash Memory Precautions
Observe the following precautions to protect the flash memory and ensure
proper operation.
1, 2, 3...
7-2
CPM2B Test Run Procedure
1, 2, 3...
114
1. If changes are made in the read-only DM area (DM 6144 through DM 6599)
or PC Setup (DM 6600 through DM 6655), the PC’s operating mode must be
changed to write the new contents to flash memory. If backup battery is replaced before the changes are written to flash memory, the changes will be
lost.
The changes can be saved by switching the CPM2B to RUN or MONITOR
mode or turning the CPM2B OFF and then ON again.
2. When contents of the program, read-only DM (DM 6144 through DM 6599),
or PC Setup (DM 6600 through DM 6655) have been changed, startup processing will take up to 1,200 ms longer than usual. Be sure to take this onetime startup delay into account if it may affect operations.
3. If one of the following three operations is performed in MONITOR or RUN
mode, the CPM2B’s cycle time will be extended by up to 1,200 ms and interrupts will be disabled while the program or PC Setup is being overwritten.
• Program changes with the online edit operation
• Changes to the read-only DM area (DM 6144 through DM 6599)
• Changes to the PC Setup (DM 6600 through DM 6655)
A “SCAN TIME OVER” error won’t occur during these operations. Be sure to
take this delay in the CPM2B’s I/O response times into account when performing online editing.
1. Power Supply Application
a) Check the CPM2B’s power supply voltage and terminal connections.
b) Check the I/O devices’ power supply voltage and terminal connections.
c) Turn on the power supply and check that the “PWR” indicator lights.
Section
Self-diagnostic Functions

7-3
d) Use a Programming Device to set the CPM2B to PROGRAM mode.
I/O Wiring Checks
a) With the CPM2B in PROGRAM mode, check the output wiring by turning
on the output bits with the force set and force reset operations.
b) Check the input wiring with the CPM2B’s input indicators or a Programming Device’s monitor operations.
Test Run
a) Use a Programming Device to set the CPM2B to RUN or MONITOR
mode and check that the “RUN” indicator lights.
b) Check the sequence of operation with the force set/reset operations, etc.
Debugging
Correct any programming errors that are detected.
Saving the Program
a) Use a Programming Device to write the program to a backup floppy disk.
b) Print out a hard copy of the program with a printer.
Note Refer to Section 4 Using Programming Devices for details on the Support Software and Programming Console operations.
7-3
Self-diagnostic Functions
The CPM2B is equipped with a variety of self-diagnostic functions to help identify and correct errors and reduce down time.
7-3-1 Identifying Errors
An error can be identified by the error message displayed on a Programming
Device, error flags in the AR and SR areas, and the error code output to SR 253.
Fatal and Non-fatal
Errors
PC errors are divided into 2 categories based on the severity of the errors. The
status of the ERR indicator (lit or flashing) shows which type of error has occurred.
ERR Lit (Fatal Error)
Fatal errors are serious errors which stop CPM2B operation. There are two ways
to restart operation:
• Turn the PC off and then on again.
• Use a Programming Device to switch the PC to PROGRAM mode, and read/
clear the error.
ERR Flashing (Non-fatal Error)
Non-fatal errors are less serious errors which don’t stop CPM2B operation.
Error Messages
When an error is detected, a corresponding error message will be displayed on
the Programming Console or other Programming Device connected to the PC.
Error Flags
When a hardware error is detected, the corresponding error flag in the AR or SR
area will be turned ON.
Error Code
When an error is detected, a specific 2-digit hexadecimal error code is output to
SR 25300 to SR 25307. The error code and time of occurrence are also output to
the Error Log Area (DM 2000 to DM 2021).
! WARNING When the CPM2B’s self-diagnosis function detects a fatal error or when a
severe failure alarm (FALS) instruction is executed, PC operation will stop and
all outputs will be turned OFF. External safety measures must be provided to
ensure safety in the system. Not providing proper safety measures may result in
serious accidents.
115
Section
Self-diagnostic Functions
7-3
7-3-2 User-defined Errors
There are three instructions that can be used to define errors or messages.
FAL(06) causes a non-fatal error, FAL(07) causes a fatal error, and MSG(46)
sends a message to the Programming Console or host computer connected to
the PC.
FAILURE ALARM –
FAL(06)
FAL(06) is an instruction that causes a non-fatal error. The following will occur
when an FAL(06) instruction is executed:
1, 2, 3...
1. The ERR indicator on the CPU Board will flash. PC operation will continue.
2. The instruction’s 2-digit BCD FAL number (01 to 99) will be written to
SR 25300 to SR 25307.
The FAL numbers can be set arbitrarily to indicate particular conditions, but the
same number should not be used as both an FAL number and an FALS number.
To clear an FAL error, correct the cause of the error and then execute FAL 00 or
use a Programming Device to clear the error.
SEVERE FAILURE ALARM –
FALS(07)
FALS(07) is an instruction that causes a fatal error. The following will occur when
an FALS(07) instruction is executed:
1, 2, 3...
1. Program execution will be stopped and all outputs will be turned OFF.
2. The ERR indicator on the CPU Board will be lit.
3. The instruction’s 2-digit BCD FALS number (01 to 99) will be written to
SR 25300 to SR 25307.
The FALS numbers can be set arbitrarily to indicate particular conditions, but the
same number should not be used as both an FAL number and an FALS number.
To clear an FALS error, use a Programming Device to switch the PC to PROGRAM Mode, correct the cause of the error, and then clear the error.
MESSAGE – MSG(46)
MSG(46) is used to display a message on a Programming Device connected to
the CPM2B. The message, which can be up to 16 characters long, is displayed
when the instruction’s execution condition is ON.
7-3-3 Non-fatal Errors
PC operation and program execution will continue after one or more of these
errors have occurred. Although PC operation will continue, the cause of the error
should be corrected and the error cleared as soon as possible.
When one of these errors occurs, the POWER and RUN indicators will remain lit
and the ERR indicator will flash.
Message
SYS FAIL FAL**
(** is 01 to 99 or 9B.)
FAL No.
Meaning and appropriate response
01 to 99
An FAL(06) instruction has been executed in the program. Check the FAL number to
determine conditions that would cause execution, correct the cause, and clear the
error.
9B
An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and
correct as directed.
AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to
DM 6614) when power was turned on. Correct the settings in PROGRAM Mode and
turn on the power again.
AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to
DM 6644) when switching to RUN or MONITOR mode. Correct the settings in
PROGRAM Mode and switch to RUN or MONITOR mode again.
AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to
DM 6655) during operation. Correct the settings and clear the error.
SCAN TIME OVER
Battery error
(no message)
116
F8
The cycle time has exceeded 100 ms. (SR 25309 will be ON.)
F7
This indicates that the program cycle time is longer than recommended. Reduce cycle
time if possible. (The CPM2B can be set so that this error won’t be detected.)
If the voltage of the C500-BAT08 backup battery is below the minimum level, the ERR
indicator will flash and SR 25308 will be turned ON.
Replace the battery. (See 7-6 Battery Replacement for details.)
Section
Self-diagnostic Functions
7-3
7-3-4 Fatal Errors
PC operation and program execution will stop and all outputs from the PC will be
turned OFF when any of these errors have occurred. CPM2B operation can’t be
restarted until the PC is turned off and then on again or a Programming Device is
used to switch the PC to PROGRAM mode and clear the fatal error.
All CPU Board indicators will be OFF for the power interruption error. For all
other fatal operating errors, the POWER and ERR indicators will be lit. The RUN
indicator will be OFF.
