WARNING
Do not attempt to take any Unit apart while the power is being supplied.
Doing so may result in electric shock.
Do not touch any of the terminals or terminal blocks while the power is being
supplied.
Doing so may result in electric shock.
Provide safety measures in external circuits (i.e., not in the Programmable Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation.
Not doing so may result in serious accidents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
• 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. Unexpected operation, however, may still occur for errors in the I/O control section, errors in I/O memory, and errors that cannot be detected by the self-diagnosis function. As a
countermeasure for all these errors, external safety measures must be provided to
ensure safety in the system.
• The PLC outputs may remain ON or OFF due to deposition 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-VDC output (service power supply to the PLC) is overloaded or shortcircuited, 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.
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.
Serious accidents may result from abnormal operation if proper measures are not
provided.
Do not apply the voltage/current outside the specified range to this unit.
It may cause a malfunction or fire.

Caution
Be sure to sufficiently confirm the safety at the destination when you transfer
the program or I/O memory or perform procedures to change the I/O memory.
Devices connected to PLC outputs may incorrectly operate regardless of the operating mode of the CPU Unit.
With an E-type CPU Unit or with an N/NA-type CPU Unit without a Battery, the contents of the DM Area (D) * , Holding Area (H), the Counter Present Values (C), the
status of Counter Completion Flags (C), and the status of bits in the Auxiliary Area (A)
related to clock functions may be unstable when the power supply is turned ON.
*This does not apply to areas backed up to EEPROM using the DM backup function.
If the DM backup function is being used, be sure to use one of the following methods
for initialization.
1. Clearing All Areas to All Zeros
Select the Clear Held Memory (HR/DM/CNT) to Zero Check Box in the Startup
Data Read Area in the PLC Setup.
2. Clearing Specific Areas to All Zeros or Initializing to Specific Values
Make the settings from a ladder program.
If the data is not initialized, the unit or device may operate unexpectedly because of
unstable data.
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.
Tighten the screws on the terminal block of the AC power supply section to the
torque specified in the user’s manual.
The loose screws may result in burning or malfunction.
Do not touch the power supply section when power is being supplied or immediately after the power supply is turned OFF.

Caution
Pay careful attention to the polarities (+/-) when wiring the DC power supply.
A wrong connection may cause malfunction of the system.
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
power supply at all.
Otherwise the external power supply may be shorted depending on the connection
methods of the peripheral device. DO NOT ground the 24 V-side of the external
power supply, as shown in the following diagram.

The DM Area (D), Holding Area (H), Counter Completion Flags (C), and Counter
Present Values (C) will be held by the Battery if a Battery is mounted in a CP1EN/NAD- CPU Unit. When the battery voltage is low, however, I/O memory
areas that are held (including the DM, Holding, and Counter Areas) will be unstable.
The unit or device may operate unexpectedly because of unstable data.
Use the Battery Error Flag or other measures to stop outputs if external outputs are performed from a ladder program based on the contents of the DM
Area or other I/O memory areas.
Sufficiently check safety if I/O bit status or present values are monitored in the
Ladder Section Pane or present values are monitored in the Watch Pane.
If bits are set, reset, force-set, or force-reset by inadvertently pressing a shortcut key,
devices connected to PLC outputs may operate incorrectly regardless of the operating mode.
Program so that the memory area of the start address is not exceeded when
using a word address or symbol for the offset.
For example, write the program so that processing is executed only when the indirect
specification does not cause the final address to exceed the memory area by using
an input comparison instruction or other instruction.
If an indirect specification causes the address to exceed the area of the start address,
the system will access data in other area, and unexpected operation may occur.

Installation
• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any
static build-up. Not doing so may result in malfunction or damage.
• 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.
Wiring
• Wire correctly according to specified procedures in this manual.
• Always use the following size wire when connecting I/O terminals: AWG22 to AWG18 (0.32 to
0.82 mm2).
• Install external breakers and take other safety measures against short-circuiting in external wiring.
Insufficient safety measures against short-circuiting may result in burning.
• Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground
of 100 Ω or less may result in electric shock.
• Leave the label attached to the top of the Unit when wiring to prevent the entry of foreign matter.
Removing the label may result in malfunction if foreign matter enters the Unit.
• 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.
• Disconnect the functional ground terminal when performing withstand voltage tests. Not disconnecting the functional ground terminal may result in burning.

Tél: 03 25 71 31 65 Fax: 03 25 74 38 82 Email: electronique@d3e.fr www.d3e.fr
• Be sure that all the PLC terminal screws and cable connector screws are tightened to the torque
specified in the relevant manuals. The tightening torque for the terminals on the CP1WCIF11/CIF12 terminal block is 0.28 N·m Incorrect tightening torque may result in malfunction.
• The following devices can be connected to pin 6 (+5V) on the built-in RS-232C port on the CPU
Unit or the RS-232C Option Board (CP1W-CIF01) mounted to the CPU Unit. Do not connect pin 6
to any other device.
• RS-422A CJ1W-CIF11 Conversion Adapter
• RS-232C / RS-422A NT-AL001 Conversion Adapter
• NV3W-M20L Programmable Terminal
• Use the cables that are specified in the manual for each device. External devices or the CPU Unit
may be damaged if a commercially available RS-232C computer cable is used.
• 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 or other wiring lines. Doing so may break the cables.
Handling
• To initialize the DM Area, back up the initial contents for the DM Area to backup memory using
one of the following methods.
• Set the number of words of the DM Area to be backed up starting with D0 in the Number of CH
of DM for backup Box in the Startup Data Read Area.
• Include programming to back up specified words in the DM Area to built-in EEPROM by turning
ON A751.15 (DM Backup Save Start Bit).
• Check the ladder program for proper execution before actually running it on the Unit. Not checking
the program may result in an unexpected operation.
• The ladder program and parameter area data in the CP1E CPU Units are backed up in the built-in
EEPROM backup 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 and a memory error
will occur the next time the power supply is turned ON.
• With a CP1E CPU Unit, data memory can be backed up to the built-in EEPROM backup memory.
The BKUP indicator will light on the front of the CPU Unit when backup is in progress. Do not turn
OFF the power supply to the CPU Unit when the BKUP indicator is lit. If the power is turned OFF
during a backup, the data will not be backed up and will not be transferred to the DM Area in RAM
the next time the power supply is turned ON.
• Before replacing the battery, supply power to the CPU Unit for at least 30 minutes and then complete battery replacement within 5 minutes. Memory data may be corrupted if this precaution is
not observed.
• The equipment may operate unexpectedly if inappropriate parameters are set. Even if the appropriate parameters are set, confirm that equipment will not be adversely affected before transferring the parameters to the CPU Unit.
• After replacing the CPU Unit, make sure that the required data for the DM Area, Holding Area, and
other memory areas has been transferred to the new CPU Unit before restarting operation.
• Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
• 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.
• 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.

• 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 Units or Board, static electricity can destroy LSIs or ICs. Cover the
PCBs with a conductive material and maintain the specified storage temperature.
• Do not touch circuit boards or the components mounted to them with your bare hands. There are
sharp leads and other parts on the boards that may cause injury if handled improperly.
• Double-check the pin numbers when assembling and wiring the connectors.
• 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 battery 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.
• Dispose of the product and batteries according to local ordinances as they apply.
• UL standards require that only an experienced engineer can replace the battery. Make sure that
an experienced engineer is in charge of battery replacement. Follow the procedure for battery
replacement given in this manual.
• The following precaution must be displayed on all products that contain a lithium primary battery
(containing at least 6 ppb of perchlorate) and that will be exported to or transported through the
State of California in the USA.
Perchlorate Material - special handling may apply. See
http://www.dtsc.ca.gov/hazardouswaste/perchlorate
A CP1W-BAT01 or CJ1W-BAT01 lithium primary battery (containing at least 6 ppb of perchlorate)
can be mounted in a CP1E-N/NAD- CPU Unit. Display the precaution given above on your
product’s packaging box or shipping box if the product contains a CP1W-BAT01 or CJ1W-BAT01
Battery and is exported to or through the State of California in the USA.
• This product is EMC compliant when assembled in a complete PLC system. Refer to the applicable manual for grounding, cable selection, and any other conditions for EMC compliance.
• This is a Class A product for use in industrial environments. In residential environments it may
cause radio interference, in which case the user may be required to take adequate measures to
reduce interference.
External Circuits
• Always configure the external circuits to turn ON power to the PLC before turning ON power to the
control system. 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 terminals 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 instruction, all outputs from PLC will be turned OFF and only the internal output status in the CPU Unit will be maintained.)

Regulations and Standards
Conformance to EC Directives
Applicable Directives
• EMC Directives
• Low Voltage Directive
Concepts
EMC Directives
OMRON devices are electrical components that are designed to be built into equipment and manufacturing systems. OMRON devices that comply with EMC Directives also conform to the related
EMC standards*, so that they can be more easily built into other devices or the overall machine.
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.
* The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.
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 PLC (EN 61131-2).
Conformance to EC Directives
The CP1E PLCs comply with EC Directives. To ensure that the machine or device in which the
CP1E PLC is used complies with EC Directives, the PLC must be installed as follows:
• The CP-series PLC must be installed within a control panel.
• CP-series 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.
• A SYSMAC CP-series PLC is a class A product (for an industrial environment). In residential
areas it may cause radio interference, in which case the user may be required to take adequate
measures to reduce interference.

• High-speed counters can be used for high-speed processing, using either target value comparison or
range comparison with the counter’s PV to create 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) can be measured.
The input pulse frequency can be measured using the PRV instruction (counter 0 only).

Use the external power supply to power input devices. Do not use it to drive output devices.
This is the rated value for the maximum system configuration. Use the following formula to calculate power consumption for CPU Units with DC power.
Formula: DC power consumption = (5V current consumption × 5 V/70% (internal power efficiency) + 24V current consumption) × 1.1(current fluctuation factor)
The above calculation results show that a DC power supply with a greater capacity is required.

Scheduled interrupts
Host Link commands can be sent from a PT or a computer to read/write I/O
memory, and perform other operations for PLC.
I/O instructions for communications ports (TXD/RXD instructions) can be used
for data transfer with peripheral devices such as bar code readers.
I/O memory in the PLC can be allocated and directly linked to various PT functions, including status control areas, status notification areas, touch switches,
lamps, memory tables, and other objects.
Up to 10 words of data per Unit can be shared between up to nine CPU Units
(one polling unit and eight polled units).
* A PT cannot be conneected.
Modbus-RTU commands are sent by the Modbus-RTU Master function. Modbus slaves, such as inverters, can be easily controlled with serial communications.
Tasks can be executed at a specified interval (1.0 ms min., Unit: 0.1 ms).
Input interrupts
Interrupt tasks are processed when the built-in input turns ON or OFF.
High-speed counter interrupts
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).

Fail-safe Circuits
This section describes the fail-safe circuits that must be set up outside the CP1E.
Always set up safety circuits outside of the PLC to prevent dangerous conditions in the event of errors in
the CP1E CPU Unit or external power supply.
In particular, be careful of the following points.
Timing of Supplying Power to the PLC and 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 momentarily not function properly.
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.
Safety Circuit for Errors (Outputs Turned OFF)
When any of the following errors occur, PLC operation (program execution) will stop and all outputs
from the Units will be turned OFF.
• A CPU error (watchdog timer error) or CPU on standby
• A fatal error (memory error, I/O bus error, too many I/O points error, program error, cycle time
exceeded error, or FALS error)
Be sure to 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.
Safety Circuit after a Malfunction (When an Output Remains ON)
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.
External Interlock Circuits
When the PLC controls 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 Circuits
100.00
MC2
Motor
MC1 clockwise
operation
MC1
Motor
MC2 counterclock
wise operation
CP1E
100.01
5-2
A circuit like the one shown in the diagram on the left is required to prevent
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.

floor.
WARNING
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.
Precautions for Correct Use
After the power supply has been turned OFF, wait until the PLC has sufficiently cooled before
touching it.

5 Installation and Wiring
AC Power Supply Wiring
• 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.
• Use a power supply within the allowable voltage fluctuation range (85 to 264 VAC).
Grounding
• Always ground the ground terminal to 100 Ω or less to protect against electric shock and incorrect
operation from electrical noise.
• 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.
• 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.
Isolation Transformer
The PLC’s internal noise isolation circuits are sufficient to control typical noise in power supply lines.
Ground noise can be further reduced by providing the power supply through a 1:1 isolating transformer. Do not ground the secondary coil of the transformer.
WARNING
Tighten the AC power supply terminal screws to a torque of 0.5 N·m.
Loose screws may result in fire or malfunction.
Precautions for Correct Use
• Loose pieces of wires may fall in the area when wiring. To prevent these pieces from entering
into the Unit, leave the label on the top of the Unit while wiring.
• Remove the label after the completion of wiring to ensure proper heat dissipation.
• The power supply terminals are located at the top of the Unit. Do not connect a power supply
to the 24-VDC external supply terminals on the bottom of the Unit. Internal circuits may be
damaged if power is supplied to these terminals.

• M3 self-rising terminal screws are used. Tighten the terminal block screws to the torque of 0.5
N·m.
• Use a power supply within the allowable voltage fluctuation range (20.4 to 26.4 VDC).
• The maximum power consumption is 20 W for N30/40/60 or NA20 CPU Units, 13 W for N14/20
CPU Units, 9W for E10 CPU Units.
• There will be a inrush current of about five times that level when the power is turned ON.
Grounding
• Always ground the ground terminal to 100Ω or less to protect against electric shock and incorrect
operation from electrical noise.
• The GR terminal is a ground terminal. To prevent electrical shock, use a dedicated ground line
(2mm2 min.) of 100Ω 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.
Precautions for Safe Use
• Be sure not to reverse the positive and negative leads when wiring the power supply terminals.
• Supply power to all of the Power Supply Units from the same source.
• Use reinforced insulation or double insulation for the DC power supplies connected to DC
Power Supply Units to comply with EC(Low Voltage Directive) Directives.

5 Installation and Wiring
Precautions When Connecting a Two-wire DC Sensor
When using a two-wire sensor with a 24-VDC input device, check that the following conditions have
been met. Failure to meet these conditions may result in operating errors.
(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)
5-3 Wiring
Power W≥(VCC −VR)2/R × 4(allowable margin)
(3) Relation between current when the PLC is OFF and sensor leakage current:
IOFF≥Ileak
5
Connect a bleeder resistor if Ileak is greater than IOFF.
Use the following equation to calculate the bleeder resistance constant.

(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.

Programming Example
In this example, the sensor’s power supply voltage is used as the input to CIO 0.00.
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
Protective Circuit for Load Short-circuits
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. Connect a TTL Unit through a CMOS-IC. It is necessary to connect a pull-up resistor for a
transistor output.
Precautions on Inrush Current
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.

Relay Output Noise Reduction Methods
The CP1E PLCs conforms to the Common Emission Standards (EN61131-2) of the EMC Directives.
However, noise generated by relay output switching may not satisfy these Standards.
In such a case, a surge protector must be connected to the load side or other appropriate countermeasures must be provided outside 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 (Refer to EN 61131-2 for details.)
• 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.

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

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.
If the supply voltage is 24 or 48 V, insert
the arc killer in parallel with the load. If
the supply voltage is 100 to 200V, insert
the arc killer between the contacts.
These values, however, vary with the load
and the characteristics of the relay.
DC
OK
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 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.
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 or 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.
• When switching a load with a high inrush current such as an incandescent lamp, suppress the
inrush current as shown below.

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.
Varistor method
Power
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.
5-3 Wiring
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.

Unit Replacement Precautions
Check the following when replacing any faulty Units discovered during inspections.
• 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.
Precautions for Correct Use
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 data area and other data are not correct for the user program, unexpected accidents may
occur.

Replacing the Battery in N/NA-type
CPU Units
For CP1E N/NA-type CPU Units, the data in the following areas may be unstable when the power is
turned ON.
Mount the CP1W-BAT01 Battery (sold separately) to an N/NA-type CPU Unit if data in the following
areas need to be retained after a power interruption.
• DM Area (D) (excluding words backed up to the EEPROM using the DM backup function )
• Holding Area (H)
• Auxiliary Area related to clock function (A)
A Battery cannot be mounted to an E-type CPU Unit.
The procedure to replace the Battery on an N/NA-type CPU Unit is given below.
Battery Service Life and Replacement Period
At 25ºC, the maximum service life for the Battery 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).

7 Maintenance and Inspection
Low Battery Indications
The ERR/ALM indicator on the front of the CPU Unit will flash when the Battery is nearly discharged.
Flashing
When the ERR/ALM indicator flashes, connect the CX-Programmer to the peripheral USB port and
read the error messages.
If a low Battery message appears on the CX-Programmer or the Battery Error Flag (A402.04) is ON,
first check whether the Battery is properly connected to the CPU.
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 (at an ambient temperature of 25°C)
before the Battery fails assuming that power has been supplied at least once a day.
You can prevent losing data in the RAM by ensuring that the CPU Unit power is not turned OFF until the
Battery is replaced.
Precautions for Correct Use
• The low battery message will appear on the CX-Programmer and the Battery Error Flag
(A402.04) will turn ON only if the Detect Low Battery parameter in the PLC Setup has been set
to detect a low-Battery error.
If this setting has not been made, Battery errors will not be detected.
• The Battery will discharge faster at higher temperatures, e.g., 4 days at 40°C and 2 days at
55°C.

7 Maintenance and Inspection
Replacing the Battery
Use the following procedure to replace the Battery when the previous Battery has become completely
discharged.
Precautions for Safe Use
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.
1
Turn OFF the power supply to the N/NA-type CPU Unit.
If the CPU Unit has not been ON, turn it ON for at least 30 minutes and then turn it OFF.
Additional Information
There is a capacitor inside the N/NA-type CPU Unit that backs up memory when the Battery is
removed. If power is not turned ON for at least 30 minutes before replacing the Battery, the
capacitor will not be fully charged and memory may be unstable before the new Battery is
inserted.
2
Open the compartment on the CPU Unit and carefully draw out the Battery. Remove the Battery
connector. Connect the new Battery, place it into the compartment, and close the cover.
7-2 Replacing the Battery in N/NA-type CPU Units
After replacing the Battery, connect a Programming Device and clear the Battery error.

7 Maintenance and Inspection
Precautions for Safe Use
• You must complete this procedure within 5 minutes after turning OFF the power to the CPU
Unit to ensure memory backup.
If the Battery is removed for more than 5 minutes, data retained by the I/O memory (excluding
the DM Area words saved to the backup memory) may be unstable.
• 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, heat, burn, or rupture, resulting in injury, fire, and possible loss of property.
Also, never use a Battery that has been dropped on the floor or otherwise subject to shock. It
may leak.
UL standards require that batteries be replaced by experienced technicians. Always place an
experienced technician in charge of Battery replacement.
• 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.
Additional Information
The Battery error will be cleared automatically the next time the CPU Unit is turned ON after
replacing the Battery.

For example, if connected 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.
• If a disconnection occurs at point C in the diagram, the negative (-) side will be used 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.

• The Analog Input Unit will not start converting analog I/O values until the range code has
been written.
The conversion data will be 0000 until the range code is written.
• Once the settings have been made, it is not possible to change the settings while power
is being supplied to the CPU Unit. To change the range code or other settings, turn the
CPU Unit OFF then ON again.
(3) 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.

(4) Reading Analog Input Conversion Values
The ladder program can be used to read the memory area words where the converted values are stored.
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.
(5) 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.

(6) Handling Unit Errors
• When an error occurs in an Analog Input Unit, the analog input conversion data
becomes 0000.
• Expansion Unit errors are output to bits 0 to 5 of word A436 for Units 1 to 3. The bits are
allocated from A436.00 in order starting with the Unit nearest the CPU Unit. CP1WAD041 is allocated two bits each. Use these flags in the program when it is necessary to
detect errors.

Precautions for Correct Use
• Connect the shield to the FG terminal to prevent noise.
• Separate wiring from power lines (AC power supply lines, high-voltage lines, etc.)
• When there is noise in the power supply line, install a noise filter on the input section and the
power supply.
Additional Information
When external power is supplied (when setting the range code), or when there is a power interruption, a pulse-form analog output may be generated.
If this causes problems with operation, take countermeasures such as those suggested below.
(1) Countermeasure 1
• Turn ON the power supply for the CP1E CPU Unit first, confirm correct operation, and then
turn ON the power supply for the load.
• Turn OFF the power supply for the load before turning OFF the power supply for the CP1E
CPU Unit.
(2) Countermeasure 2
• Control the machine not only by analog output but also by other signals (additional start/stop
control signal for machine).

(3) Writing Analog Output Set Values
The ladder program can be used to write data to the output word where the set value is
stored.
When “n” is the last output word allocated to the CPU Unit, or previous Expansion Unit or
Expansion I/O Unit, the output words will be n+1 to n+2 for CP1W-DA021 and n+1 to n+4
for CP1W-DA041.
(4) 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.

(5) 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 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 5 of word A436 for
units 1 to 3. The bits are allocated from A436.00 in order starting from the Unit nearest
the CPU Unit. CP1W-DA041 is allocated two bits each and CP1W-DA021 is allocated
one bit each. Use these flags in the probgram when it is necessary to detect errors.

Other Functions
Averaging Function for Analog Inputs
The averaging function can be enabled for inputs using the DIP switch. The averaging function outputs 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.

Precautions for Correct Use
• Do not connect the shield when using shielded twisted-pair cables.
• When an input is not being used, short the + and - terminals.
• Separate wiring from power lines (AC power supply lines, high-voltage lines, etc.)
• When there is noise in the power supply line, install a noise filter on the input section and the
power supply terminals.

Example: If connected 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.
• If a disconnection occurs at point C in the diagram, the negative (-) side will be used 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.

Additional Information
When external power is supplied (when setting the range code), or when there is a power interruption, a pulse-form analog output may be generated.
If this causes problems with operation, take countermeasures such as those suggested below.
(1) Countermeasure 1
• Turn ON the power supply for the CP1E CPU Unit first, confirm correct operation, and then
turn ON the power supply for the load.
• Turn OFF the power supply for the load before turning OFF the power supply for the CP1E
CPU Unit.
(2) Countermeasure 2
• Control the machine not only by analog output but also by other signals (additional start/stop
control signal for machine).

• The Analog I/O Unit will not start converting analog I/O values until the range code has
been written. 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 10V, -10 to 10V,
or 0 to 20mA ranges, and 1 V or 4 mA will be output for the 1 to 5V and 4 to 20mA
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.
(3) Reading Analog Input Conversion 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.
(4) 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.
(5) 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.
Analog input data will be 0000 until initial processing is 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.

(6) 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 5 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.

Precautions for Correct Use
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.

(1) Words Allocation
Temperature Sensor Units are allocated words just like other CP-series as Expansion Units
or Expansion I/O Units, i.e., 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. Two input words are allocated to the 2-input CP1W-TS001 or CP1WTS101 and four input words are allocated to the 4-input CP1W-TS002 or CP1W-TS102. No
output words are allocated.

• If the input temperature exceeds the maximum or minimum value in the temperature
input range that has been set by ±20°C or ±20°F, the displayed value will be held.
• If the circuit is disconnected, the open-circuit detection function will operate and the converted temperature data will be set to 7FFF.
• 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.

Function Descriptions
Two-decimal-place Mode
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.
Additional Information
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°C
(°F). Treat any resolution above that specified for the normal data format as reference data.

I/O Words Allocation
I/O words are allocated to the CompoBus/S I/O Link Unit in the same way as to other Expansion
Units and Expansion I/O Units, i.e., the next available input and output words are allocated. As
shown below, when “m” is the last allocated input word and “n” is the last allocated output word, the
CompoBus/S I/O Link Unit is allocated “m+1” as its input word and “n+1” as its output word.

Precautions for Correct Use
The 8 bits of I/O data are not always transmitted simultaneously.
• 8 bits of data transmitted from the Master CPU Unit at the same time will not always reach the
CP1E CPU Unit.
• 8 bits of data transmitted from the CP1E 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.

Determine the node number and make DIP switch settings.
(1) Determining 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 (Cat. No. W266).
(2) Making DIP Switch Settings
Use the DIP switch to set the CompoBus/S I/O Link Unit’s node number, communications
mode, and the status of output data when a communications error occurs.
Precautions for Correct Use
Always turn OFF the power supply before changing the DIP switch settings.

input’s + and - terminals.
3 Wire I/O lines apart from power lines (AC power supply lines, three-phase power lines, etc.).
4 If noise is received from power supply lines, insert a
noise filter in the power supply input section.
5 When noise disturbs the analog input/output cable,
install the core to improve anti-noise performance.

Note The hood (FG) is internally connected to the ground terminal (GR) on the CPU Unit.
Therefore, the FG is grounded by grounding the power supply ground terminal (GR). Although there is conductivity between the hood (FG) and pin 1 (FG), connect the shield to both the hood and pin 1 to reduce the
contact resistance between the shield and FG and thus provide better noise resistance.

Precautions for Correct Use
• The XW2Z-0T-1 Connecting Cables for the NT-AL001 Link Adapter uses special wiring for
the DS and RS signals.
Do not use these signals with other devices.
Connecting this cable to other devices can damage them.
• Always turn ON the terminating resistance if the node is at the end of the RS-422A/485 transmission path.
