This manual provides information for programming and operating the Unit.
Be sure to read this manual before attempting to use the Unit and keep this
manual close at hand for reference during operation.
WARNING It is extremely important that a PLC and all PLC Units be used for the
specified 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.
Safety Precautions
WARNING Confirm safety sufficiently before transferring I/O memory area status from
the CX-Programmer to the PLC. The devices connected to Output Units
may malfunction, regardless of the operating mode of the CPU Unit.
Caution is required in respect to the following functions.
•Transferring from the CX-Programmer to real I/O (CIO Area) in the CPU
Unit using the PLC Memory window.
•Transferring from file memory to real I/O (CIO Area) in the CPU Unit
using the Memory Card window.

WARNING Observe the following precautions when using the PLC Backup Tool.
•Sufficiently check the data that is selected for restoring before performing
the next step. If the correct data is not restored, unexpected operation
may occur in the controlled system after the data is restored.
•Some Special I/O Units and CPU Bus Units operate with parameters that
are stored in the CPU Unit. If one of these Units is selected for backup,
restrictions will be displayed in the Comments Area of the Backup from
PLC Dialog Box. Confirm the restrictions, and always select the Special
I/O Unit or CPU Bus Unit together with the CPU Unit when backing up or
restoring data. If the data from both Units is not backed up or restored
together, unexpected operation may occur in the controlled system.
•If there are any backup restrictions for the Units to which data is being
restored, the restrictions will be displayed in the Comments Area of the
Backup from PLC Dialog Box. Confirm the restrictions, and always take
the required measures. If required measures are not taken, unexpected
operation may occur in the controlled system after the data is restored.
•Forced status can be backed up, but it cannot be restored. If you
restored data that contained forced status, use the CX-Programmer after
restoring the data to force-set or force-reset bits as required. If required
bits are not force-set or force-reset, differences in the forced status in
memory may cause unexpected operation of the controlled system.
•Confirm that stopping PLC operation will not create any problems before
restoring data during PLC operation. If the PLC stops at an unanticipated
time, unexpected operation may occur in the controlled system.
•Always turn the power supply to the PLC OFF and then ON after
restoring data. If the power supply is not turned OFF and then ON,
memory in the PLC may not be updated to the restored data, which may
cause unexpected operation of the controlled system.
Caution Observe the following precaution when specifying a symbol or word
address for an array variable index in a ladder program or when specifying
a symbol for an array variable index in an ST program.
When using a symbol or address to indirectly specify the element number
of an array variable, be sure that the resulting address is not outside the
memory area that contains the first word in the array. For example, use a
symbol comparison instruction or an IF statement to ensure that processing
is performed only when the memory area is not exceeded. If an element
number that exceeds the memory area is specified, data in another
memory area will be read or written, possibly resulting in unexpected
operation.
Caution Observe the following precaution when specifying a symbol or word
address for an offset in a ladder program.
When using a symbol or address to indirectly specify an offset for a
memory address, be sure that the resulting address is not outside the
memory area that contains original address. For example, use a symbol
comparison instruction to ensure that processing is performed only when
the memory area is not exceeded. If the final address (i.e., the original
address plus the specified offset) exceeds the memory area, data in
another memory area will be read or written, possibly resulting in
unexpected operation.

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 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 If synchronous unit operation is being used, perform online editing only
after confirming that an increased synchronous processing time will not
affect the operation of the main and slave axes.
Caution Confirm safety sufficiently before monitoring power flow and present value
status in the Ladder Section window or when monitoring present values in
the Watch window. If force-set/reset or set/reset operations are
inadvertently performed by pressing short-cut keys, the devices connected
to Output Units may malfunction, regardless of the operating mode of the
CPU Unit.
Caution Caution is required when connecting peripheral devices, such as a
personal computer, to the PLC when Units with non-isolated power
supplies, such as the CS1W-CLK12/CLK52(-V1), that are connected to an
external power supply are mounted to the PLC. If the 24-V side is grounded
on the external power supply, a short will be created if the 0-V side of the
peripheral device is grounded. When connecting peripheral devices, either
ground the 0-V side of the external power supply or do not ground the
external power supply at all.

Application Precaution
Observe the following precautions when using the CX-Programmer.
•Observe the following precautions before starting the CX-Programmer.
•Exit all applications not directly related to the CX-Programmer.
Particularly exit any software such as screen savers, virus checkers,
email or other communications software, and schedulers or other
applications that start up periodically or automatically.
•Disable sharing hard disks, printers, or other devices with other
computers on any network.
•With some notebook computers, the RS-232C port is allocated to a
modem or an infrared port by default. Follow the instructions in
documentation for your computer and enable using the RS-232C port
as a normal serial port.
•With some notebook computers, the default settings for saving
energy do not supply the rated power to the RS-232C port. There
may be both Windows settings for saving energy, as well as setting
for specific computer utilities and BIOS. Following the instructions in
documentation for your computer, disable all energy saving settings.
•Do not turn OFF the power supply to the PLC or disconnect the
connecting cable while the CX-Programmer is online with the PLC. The
computer may malfunction.
•With the CS/CJ-series PLCs, when creating an AUTOEXEC.IOM file
from 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. Refer to information on file operations in the CS/CJ-series
Programming Manual for details.
•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.
•Force-setting/force-resetting any bit in memory.
•Changing the present value of any word or any set value in memory.
•Check the user program for proper execution before actually running it
on the Unit. Not checking the program may result in an unexpected
operation.
•Precaution on Using Indirect DM and EM Addresses in Comparison
Instructions:
When indirect DM or EM addresses are used as operands in comparison
instructions, the top portion of the comparison instruction will be displayed
in yellow when it is being monitored. At that time the power flow will not be
monitored to the right of such comparison instructions. The contact and
coil status, and present values of operands in special instructions will be
displayed normally.

•The user program and parameter area data in CS1-H CPU Units 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.
To display the status of writing to flash memory on the CX-Programmer,
place a checkmark by Display dialog to show PLC Memory Backup
Status on the PLC properties and then select Windows | PLC Memory
Backup Status from the Windows menu.
•Precaution in Changing the PLC Type
On the CX-Programmer, you can change the PLC (device) type or CPU
type. When these are changed, however, only the data for the ladder
program and the symbol tables are changed. The following data will be
initialized and must be reset.
•PLC Setup
•Expansion instructions
•I/O tables
•PLC memory
Particularly the PLC Setup has a large impact on PLC system operation.
Be careful to reset all require settings after changing the PLC type.
If expansion instruction allocations are not reset, program errors could
occur, preventing the PLC from running. Always restore the expansion
instruction allocates to the previous settings after changing the PLC
type.

Observe the following precautions when using the CX-Net.
• Do not change the operating mode of the CPU Unit without first
confirming that operation of the controlled system will not be affect.
• Do not run the user program on the PLC until its operation has been
checked sufficiently.
• The data link mode (manual setting or automatic setting) and data link
method are determined according to the data link setting in the startup
node. In the startup node, set a data link table in the case of manual
setting and data link automatic setting parameters in the case of
automatic setting. If the settings are incorrect, the data link will not start.
• Check the following items before starting data links. If incorrect data link
tables or parameters are set, injury may result due to unexpected
operation of the system. Even if the correct data link tables and
parameters have been set, do not start or stop data links before verifying
that there will be no adverse influence on the system.
(1) Manually Set Data Links
Check the data link tables in each node participating in the data link to
see that they are correct.
Be sure that data link tables are deleted from nodes that are not
participating in the data links.
(2) Automatically Set Data Links
Be sure that the correct DM parameters have been set in the data link
startup node.
• CPU Bus Units will be automatically restarted when routing tables are
transferred from a Programming Device to the CPU Unit. Resetting is
required to use the new tables. Confirm that restarting the CPU Bus
Units will not adversely affect system operation before transferring
routing tables.
• When Special I/O Unit or CPU Unit settings are performed in the I/O
Table Window and then transferred from the PLC Memory Window, the
following warning will be displayed if the allocated DM Area/CIO Area
addresses set for Special I/O Units or CPU Bus Units in the I/O Table
Window on the computer overlap with the PLC data table addresses.
Unless the CPU Bus Unit or Special I/O Unit settings have been
previously transferred to the CPU Unit and the allocated DM Area/CIO
Area data in the PLC data table for Special I/O Units or CPU Bus Units is
to be overwritten, always click the No Button, shift the address, and
repeat the transfer procedure.
• CPU Bus Unit and Special I/O Unit settings are not checked for logical
consistency. Be very careful of the logical consisting of the overall
settings when making any setting that affects other settings, e.g., settings
that enable or disable other settings. Transfer the Special I/O Unit or
CPU Bus Unit settings to the PLC and then start operation, being aware
that any logical inconsistencies may produce unexpected operation.
• For example, if one setting selects either user settings or default settings
and is set to use the default settings, it will not automatically change to
enable user settings even if the related user settings are made. To use
the user settings, they will have to be enabled manually and specifically
in the setting that selects either user settings or default settings.
