!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 applications.
3 Safety Precautions
!WARNING The CPU Unit 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 Unit from a Programming
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 Unit.
• 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
xxvi
so may result in electric shock.
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 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.
!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 Unit using a
Programming Device. Otherwise, the devices connected to the output unit
may malfunction regardless of the operation mode of the CPU Unit.
!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 Confirm safety at the destination node before transferring a program to
another node or changing contents of the I/O memory 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 Unit to the
torque specified in the operation manual. The loose screws may result in
burning or malfunction.
xxvii
Operating Environment Precautions 4
!Caution A CJ1-H or CJ1M CPU Unit 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, 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 inappropriate 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.
4 Operating Environment Precautions
!Caution Do not operate the control system in the following locations:
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified
in the specifications.
• Locations subject to condensation as the result of severe changes in temperature.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
!Caution Take appropriate and sufficient countermeasures when installing systems in
the following locations:
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
!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 conditions 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 programs 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
connecting to a ground of 100
• A ground of 100
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 Units is
backed up in the internal 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.
• 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 Unit will start in RUN mode. This is the default
setting in the PLC Setup. (A CS1 CPU Unit 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 Unit starting at D20000 even if another address was set when
the AUTOEXEC.IOM file was created. Also, if the DM Area is exceeded
(which is possible when the CX-Programmer is used), the remaining data
will be written to the EM Area.
Ω or less must be installed when shorting the GR and LG
Ω or less when installing the Units. Not
Ω or less may result in electric shock.
xxix
Application Precautions 5
• Always 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 Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.
• 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.
• Interlock circuits, limit circuits, and similar safety measures in external circuits (i.e., not in the Programmable Controller) must be provided by the
customer.
• Do not turn OFF the power supply to the PLC when data is being transferred. In particular, do not turn OFF the power supply when reading or
writing a Memory Card. Also, do not remove the Memory Card when the
BUSY indicator is lit. To remove a Memory Card, first press the memory
card power supply switch and then wait for the BUSY indicator to go out
before removing the Memory Card.
• 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.)
• The contents of the DM, EM, and HR Areas in the CPU Unit are backed
up by a Battery. If the Battery voltage drops, this data may be lost. Provide
countermeasures in the program using the Battery Error Flag (A40204) to
re-initialize data or take other actions if the Battery voltage drops.
• Always use the power supply voltages 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.
• 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 Units in excess of the rated input voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the Output Units in excess of
the maximum switching capacity. Excess voltage or loads may result in
burning.
• Separate the line ground terminal (LG) from the functional ground terminal (GR) on the Power Supply Unit before performing withstand voltage
tests or insulation resistance tests. Not doing so may result in burning.
• Install the Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.
xxx
Application Precautions 5
• Be sure that all the terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening
torque may result in malfunction.
• Leave the label attached to the Unit when wiring. 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.
• Wire all connections correctly.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Mount Units only after checking terminal blocks and connectors completely.
• Be sure that the terminal blocks, Memory Units, expansion cables, and
other items with locking devices are properly locked into place. Improper
locking may result in malfunction.
• Check switch settings, the contents of the DM Area, and other preparations before starting operation. Starting operation without the proper settings or data may result in an unexpected 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.
• 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.
• Resume operation only after transferring to the new CPU Unit the contents of the DM Area, HR Area, and other data required for resuming
operation. Not doing so may result in an unexpected operation.
• 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.
• Do not use commercially available RS-232C personal computer cables.
Always use the special cables listed in this manual or make cables
according to manual specifications. Using commercially available cables
may damage the external devices or CPU Unit.
• Do not connect pin 6 (+5 V power supply line) of the RS-232C port on the
CPU Unit to any external device except the CJ1W-CIF11 RS-422A
Adapter or NT-AL001 RS-232C/RS-422A Adapter. Doing so may damage
the external device or CPU Unit.
• 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 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.
