Confirming Unit Versions
with Support Software

CP1H-XA40DR-A

A “unit version” has been introduced to manage CPU Units in the CP Series
according to differences in functionality accompanying Unit upgrades.

The unit version is given to the right of the lot number on the nameplate of the
products for which unit versions are being managed, as shown below.

CP-series CPU Unit

Unit version (Example for Unit version 1.0)

CX-Programmer version 6.1 or higher can be used to confirm the unit version
using one of the following two methods. (See note.)

• Using the PLC Information

• Using the Unit Manufacturing Information

Note CX-Programmer version 6.1 or lower cannot be used to confirm unit versions

for CP-series CPU Units.

PLC Information

• If you know the device type and CPU type, select them in the Change
PLC Dialog Box, go online, and select PLC - Edit - Information from the

menus.

• If you don't know the device type and CPU type but are connected directly
to the CPU Unit on a serial line, select PLC - Auto Online to go online,
and then select PLC - Edit - Information from the menus.

In either case, the following PLC Information Dialog Box will be displayed.

vi

Unit version

Use the above display to confirm the unit version of the CPU Unit.

Unit Manufacturing Information

In the IO Table Window, right-click and select Unit Manufacturing informa­tion - CPU Unit.

The following Unit Manufacturing information Dialog Box will be displayed.

vii

Unit version

Use the above display to confirm the unit version of the CPU Unit connected
online.

Using the Unit Version
Labels

The following unit version labels are provided with the CPU Unit.

Ver.

About this Manual:

This manual describes installation and operation of the CP-series Programmable Controllers (PLCs)
and includes the sections described below. The CP Series provides advanced package-type PLCs
based on OMRON’s advanced control technologies and vast experience in automated control.

Please read this manual carefully and be sure you understand the information provided before
attempting to install or operate a CP-series PLC. Be sure to read the precautions provided in the fol­lowing section.

Definition of the CP Series

The CP Series is centered around the CP1H CPU Units and is designed with the same basic architec­ture as the CS and CJ Series. The Special I/O Units and CPU Bus Units of the CJ Series can thus be
used. CJ-series Basic I/O Units, however, cannot be used. Always use CP-series Expansion Units and
CP-series Expansion I/O Units when expanding I/O capacity.

I/O words are allocated in the same way as the CPM1A/CPM2A PLCs, i.e., using fixed areas for inputs
and outputs.

fied purpose and under the specified conditions, especially in applications that
can directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PLC System to the above-mentioned appli­cations.

3 Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing

so may result in electric shock.

!WARNING Do not touch any of the terminals or terminal blocks while the power is being

supplied. Doing so may result in electric shock.

!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do

so may result in malfunction, fire, or electric shock.

!WARNING 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.

xxiv

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

Safety Precautions 3

• 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 or outputs may remain ON or OFF due to deposits on or burning
of the output relays, or destruction of the output transistors. As a counter­measure for such problems, external safety measures must be provided
to ensure safety in the system.

• When the 24-V DC output (service power supply to the PLC) is over­loaded or short-circuited, the voltage may drop and result in the outputs
being turned OFF. As a countermeasure for such problems, external
safety measures must be provided to ensure safety in the system.

!WARNING Fail-safe measures must be taken by the customer to ensure safety in the

event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or other causes. Not doing so may result in
serious accidents.

!WARNING Do not apply the voltage/current outside the specified range to this unit. It may

cause a malfunction or fire.

!Caution Execute online edit only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be
readable.

!Caution Confirm safety at the destination node before transferring a program to

another node or editing the I/O area. Doing either of these without confirming
safety may result in injury.

!Caution Tighten the screws on the terminal block of the AC power supply to the torque

specified in this manual. The loose screws may result in burning or malfunc­tion.

!Caution Do not touch anywhere near the power supply parts or I/O terminals while the

power is ON, and immediately after turning OFF the power. The hot surface
may cause burn injury.

!Caution Pay careful attention to the polarities (+/-) when wiring the DC power supply. A

wrong connection may cause malfunction of the system.

!Caution After programming (or reprogramming) using the IOWR instruction, confirm

that correct operation is possible with the new ladder program and data before
starting actual operation. Any irregularities may cause the product to stop
operating, resulting in unexpected operation in machinery or equipment.

!Caution The CP1H CPU Units automatically back up the user program and parameter

data to flash memory when these are written to the CPU Unit. I/O memory
(including the DM Area, counter present values and Completion Flags, and
HR Area), however, is not written to flash memory. The DM Area, counter
present values and Completion Flags, and HR Area can be held during power
interruptions with a battery. If there is a battery error, the contents of these
areas may not be accurate after a power interruption. If the contents of the
DM Area, counter present values and Completion Flags, and HR Area are
used to control external outputs, prevent inappropriate outputs from being
made whenever the Battery Error Flag (A402.04) is ON.

Application Precautions 5

• Always use the power supply voltage specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.

• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.

• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction.

• Remove the label after the completion of wiring to ensure proper heat dis­sipation. Leaving the label attached may result in malfunction.

• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.

• Do not apply voltages to the input terminals in excess of the rated input
voltage. Excess voltages may result in burning.

• Do not apply voltages or connect loads to the output terminals in excess
of the maximum switching capacity. Excess voltage or loads may result in
burning.

• Be sure that the terminal blocks, connectors, Option Boards, and other
items with locking devices are properly locked into place. Improper locking
may result in malfunction.

• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.

• Wire correctly and double-check all the wiring or the setting switches before
turning ON the power supply. Incorrect wiring may result in burning.

• Check that the DIP switches and data memory (DM) are properly set
before starting operation.

• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected opera­tion.

• Resume operation only after transferring to the new CPU Unit and/or Spe­cial I/O Units the contents of the DM, HR, and CNT Areas required for
resuming operation. Not doing so may result in an unexpected operation.

• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.

• Changing the operating mode of the PLC (including the setting of the
startup operating mode).

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.

• Do not place objects on top of the cables. Doing so may break the cables.

• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.

• Before touching the Unit, be sure to first touch a grounded metallic object
in order to discharge any static buildup. Not doing so may result in mal­function or damage.

Application Precautions 5

• Do not touch the Expansion I/O Unit Connecting Cable while the power is
being supplied in order to prevent malfunction due to static electricity.

• Do not turn OFF the power supply to the Unit while data is being trans­ferred.

• When transporting or storing the product, cover the PCBs and the Units or
put there in the antistatic bag with electrically conductive materials to pre­vent LSls and ICs from being damaged by static electricity, and also keep
the product within the specified storage temperature range.

• Do not touch the mounted parts or the rear surface of PCBs because
PCBs have sharp edges such as electrical leads.

• Double-check the pin numbers when assembling and wiring the connec­tors.

• Wire correctly according to specified procedures.

• Do not connect pin 6 (+5V) on the RS-232C Option Board on the CPU
Unit to any external device other than the NT-AL001 or CJ1W-CIF11 Con­version Adapter. The external device and the CPU Unit may be damaged.

• Use the dedicated connecting cables specified in this manual to connect
the Units. Using commercially available RS-232C computer cables may
cause failures in external devices or the CPU Unit.

• Check that data link tables and parameters are properly set before start­ing operation. Not doing so may result in unexpected operation. Even if
the tables and parameters are properly set, confirm that no adverse
effects will occur in the system before running or stopping data links.

• Transfer a routing table to the CPU Unit only after confirming that no
adverse effects will be caused by restarting CPU Bus Units, which is auto­matically done to make the new tables effective.

• The user program and parameter area data in the CPU Unit is backed up
in the built-in flash memory. The BKUP indicator will light on the front of
the CPU Unit when the backup operation is in progress. Do not turn OFF
the power supply to the CPU Unit when the BKUP indicator is lit. The data
will not be backed up if power is turned OFF.

• Do not turn OFF the power supply to the PLC while the Memory Cassette
is being accessed. Doing so may corrupt the data in the Memory Cas­sette. The 7-segment LED will light to indicate writing progress while the
Memory Cassette is being accessed. Wait for the LED display to go out
before turning OFF the power supply to the PLC.

• Before replacing the battery, supply power to the CPU Unit for at least 5
minutes and then complete battery replacement within 5 minutes of turn
OFF the power supply. Memory data may be corrupted if this precaution is
not observed.

• Always use the following size wire when connecting I/O Units, Special I/O

2

Units, and CPU Bus Units: AWG22 to AWG18 (0.32 to 0.82 mm

• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries. Also,
always follow the replacement procedure provided in the manual.

• Never short-circuit the positive and negative terminals of a battery or
charge, disassemble, heat, or incinerate the battery. Do not subject the
battery to strong shocks or deform the barry by applying pressure. Doing
any of these may result in leakage, rupture, heat generation, or ignition of
the battery. Dispose of any battery that has been dropped on the floor or
otherwise subjected to excessive shock. Batteries that have been sub­jected to shock may leak if they are used.

• Always construct external circuits so that the power to the PLC it turned
ON before the power to the control system is turned ON. If the PLC power
supply is turned ON after the control power supply, temporary errors may
result in control system signals because the output terminals on DC Out­put Units and other Units will momentarily turn ON when power is turned
ON to the PLC.

• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal cir­cuit failures, which can occur in relays, transistors, and other elements.

• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be
turned OFF and will maintain their previous status when the PLC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(007) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)

• Dispose of the product and batteries according to local ordinances as
they apply.
Have qualified specialists properly dispose of used batteries as industrial
waste.

EMC Directives

OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.

EMC-related performance of the OMRON devices that comply with EC Direc­tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.

Note The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).
