!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-
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 appli-
cations.
3 Safety Precautions
!WARNING The CPU functional element refreshes I/O even when the program is stopped
(i.e., even in PROGRAM mode). Confirm safety thoroughly in advance before
changing the status of any part of memory allocated to I/O Units, Special I/O
Units, or CPU Bus Units. Any changes to the data allocated to any Unit may
result in unexpected operation of the loads connected to the Unit. Any of the
following operation may result in changes to memory status.
• Transferring I/O memory data to the CPU functional element from a Pro-
gramming Device.
• Changing present values in memory from a Programming Device.
• Force-setting/-resetting bits from a Programming Device.
• Transferring I/O memory files from a Memory Card or EM file memory to
the CPU functional element.
• Transferring I/O memory from a host computer or from another PLC on a
network.
!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing
so may result in electric shock.
xx
Safety Precautions 3
!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 Do not touch the Power Supply Unit while power is being supplied or immedi-
ately after power has been turned OFF. Doing so may result in 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.
• 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.
As a countermeasure for such 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 counter-
measure 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 over-
loaded 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.
!Caution Confirm safety before transferring data files stored in the file memory (Mem-
ory Card or EM file memory) to the I/O area (CIO) of the CPU functional ele-
ment using a Programming Device. Otherwise, the devices connected to the
Output Unit may malfunction regardless of the operation mode of the CPU
functional element.
!Caution 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.
!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 Tighten the screws on the terminal block of the AC Power Supply Unit to the
torque specified in the operation manual. The loose screws may result in
burning or malfunction.
xxi
Operating Environment Precautions 4
!Caution CJ1M CPU functional elements automatically back up the user program and
parameter data to flash memory when these are written to the CPU functional
element. I/O memory (including the DM, EM, and HR Areas), however, is not
written to flash memory. The DM, EM, and HR Areas 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, EM, and HR Areas are used to control external outputs, prevent inap-
propriate outputs from being made whenever the Battery Error Flag (A40204)
is ON. Areas such as the DM, EM, and HR Areas, the contents of which can
be held during power interrupts, is backed up by a battery. If a battery error
occurs, the contents of the areas that are set to be held may not be accurate
even though a memory error will not occur to stop operation. If necessary for
the safety of the system, take appropriate measures in the ladder program
whenever the Battery Error Flag (A40204) turns ON, such as resetting the
data in these areas.
!Caution The operating environment of the PLC System can have a large effect on the
longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified condi-
tions at installation and remains within the specified conditions during the life
of the system.

Application Precautions 5
5 Application Precautions
Observe the following precautions when using the PLC System.
• You must use the CX-Programmer (programming software that runs on
Windows) if you need to program more than one task. A Programming
Console can be used to program only one cyclic task plus interrupt tasks.
A Programming Console can, however, be used to edit multitask pro-
grams originally created with the CX-Programmer.
!WARNING Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
• 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.
• A ground of 100 Ω or less must be installed when shorting the GR and LG
terminals on the Power Supply Unit.
• Always turn OFF the power supply to the PLC before attempting any of
the following. Not turning OFF the power supply may result in malfunction
or electric shock.
• Mounting or dismounting Power Supply Units, I/O Units, CPU Units, or
any other Units.
• Assembling the Units.
• Setting DIP switches or rotary switches.
• Connecting cables or wiring the system.
• Connecting or disconnecting the connectors.
!Caution Failure to abide by the following precautions could lead to faulty operation of
the PLC or the system, or could damage the PLC or PLC Units. Always heed
these precautions.
• A CJ-series CPU Unit is shipped with the battery installed and the time
already set on the internal clock. It is not necessary to clear memory or
set the clock before application, as it is for the CS-series CPU Units.
• The user program and parameter area data in CJ1-H/CJ1M CPU func-
tional elements is backed up in the built-in flash memory. The BKUP indi-
cator 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.
• If, when using a CJ-series CPU Unit, the PLC Setup is set to specify using
the mode set on the Programming Console and a Programming Console
is not connected, the CPU functional element will start in RUN mode. This
is the default setting in the PLC Setup. (A CS1 CPU functional element
will start in PROGRAM mode under the same conditions.)
• When creating an AUTOEXEC.IOM file from a Programming Device (a
Programming Console or the CX-Programmer) to automatically transfer
data at startup, set the first write address to D20000 and be sure that the
size of data written does not exceed the size of the DM Area. When the
data file is read from the Memory Card at startup, data will be written in
the CPU functional element starting at D20000 even if another address
was set when the AUTOEXEC.IOM file was created. Also, if the DM Area

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 Direc-
tives 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 top switch sets the sixteens digit (most significant digit) and the bottom
switch sets the ones digit (least significant digit). The node address is factory-
set to 01.
Note Turn OFF the power supply before setting the node address.
Relation to IP Addresses When using the automatic generation method (either dynamic or passive) for
address conversion, set the rightmost byte of the IP address set for the Ether-
net functional elements or Ethernet Unit to the same value as the node
address. If this is not possible, either the IP address table method or the com-
bined method must be used for address conversion. (For details, refer to the
Ethernet Units Construction of Networks Operation Manual (W420).) If the
FINS communications service is not used on the Ethernet network, then it is
all right to overlap with other Ethernet functional elements or Ethernet Units.
The setting, however, must be made within a range of 01 to FE. If a value out-
side of this range is set, the ERC indicator will light.

Note The following table shows the allowable voltage fluctuation ranges for source
power supplies.
Supply voltage Allowable voltage range
100 to 240 V AC 85 to 264 V AC
24 V DC 19.2 to 28.8 V DC
Note 1. The CPU functional element and Ethernet functional element are insepa-
rable parts of the CJ1M CPU Unit with Ethernet Functions and cannot be
detached. Therefore, if either functional element is faulty, replace the entire
Unit.
29
Replacing User-serviceable Parts Section 3-2
2. 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 functional element 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. Be sure to include the routing
tables, Controller Link Unit data link tables, network parameters, and other
CPU Bus Unit data, which are stored as parameters in the CPU functional
element. Refer to the CPU Bus Unit and Special I/O Unit operation manu-
als for details on the data required by each Unit.
3. The simple backup operation can be used to store the user program and
all parameters for the CJ1M CPU functional element, DeviceNet Units, Se-
rial Communications Units, and other specific Units in a Memory Card as
backup files. A Memory Card and the simple backup operation can be
used to easily restore data after replacing any of these Units. Refer to the
CS/CJ Series Programming Manual (W394) for details.
Battery Functions The battery maintains the internal clock and the following data of the CPU
functional element’s RAM while the main power supply is OFF.
• The user program
• The PLC Setup
• Retained regions of I/O memory (such as the Holding Area and DM Area)
If the battery is not installed or battery voltage drops too low, the internal clock
will stop and the data in RAM will be lost when the main power supply goes
OFF.
Battery Service Life and At 25°C, the maximum service life for batteries is five years whether or not
Replacement Period 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 and when power
is not supplied to the CPU Unit for long periods.
The following table shows the approximate minimum lifetimes and typical life-
times for the backup battery (total time with power not supplied).

Low Battery Indicators If the PLC Setup has been set to detect a low-battery error, the ERR/ALM
indicator on the front of the CPU functional element will flash when the battery
is nearly discharged.
BATT LOW
Once a low-battery error has been detected, it will take 5 days at an ambient
temperature of 25°C (see note 2) before the battery fails assuming that power
has been supplied at lease once a day. Battery failure and the resulting loss of
data in RAM can be delayed by ensuring that the CPU Unit power is not
turned OFF until the battery has been replaced.
Note 1. The PLC Setup must be set to detect a low-battery error (Detect Low Bat-
tery). If this setting has not been made, the BATT LOW error message will
not appear on the Programming Console and the Battery Error Flag
(A40204) will not go ON when the battery fails.
2. The battery will discharge faster at higher temperatures, e.g., 4 days at
40°C and 2 days at 55°C.
31
Replacing User-serviceable Parts Section 3-2
Replacement Battery Use the CJ1W-BAT01 (for CJ1M) Battery Set. Be sure to install a replacement
battery within two years of the production date shown on the battery’s label.
CJ1M CPU Units with Ethernet Functions
Production Date
Note 1. The battery can be replaced without turning OFF the power supply. To do
so, always touch a grounded piece of metal to discharge static electricity
from your body before starting the procedure.
2. After replacing the battery, connect a Programming Device and clear the
battery error.
Procedure
The battery error will automatically be cleared when a new battery is inserted.
Note Connect the new battery within five minutes of disconnecting the old battery. If
a battery is not connected for longer than five minutes, data may be lost.
!WARNING Never short-circuit the battery terminals; never charge the battery; never dis-
assemble the battery; and never heat or incinerate the battery. Doing any of
these may cause the battery to leak, burn, or rupturing resulting in injury, fire,
and possible loss of life or property. Also, never use a battery that has been
dropped on the floor or otherwise subject to shock. It may leak.
