This manual is intended for the following personnel, who must also have knowl-
edge of electrical systems (an electrical engineer or the equivalent).
• Personnel in charge of installing FA systems.
• Personnel in charge of designing FA systems.
• Personnel in charge of managing FA systems and facilities.
The user must operate the product according to the performance specifications
described in the operation manuals.
Before using the product under conditions which are not described in the manual
or applying the product to nuclear control systems, railroad systems, aviation sys-
tems, vehicles, combustion systems, medical equipment, amusement machines,
safety equipment, and other systems, machines, and equipment that may have a
serious influence on lives and property if used improperly, consult your OMRON
representative.
Make sure that the ratings and performance characteristics of the product are suf-
ficient for the systems, machines, and equipment, and be sure to provide the sys-
tems, machines, and equipment with double safety mechanisms.
This manual provides information for installing and operating OMRON High-
speed Counter Units. Be sure to read this manual before operation and keep this
manual close at hand for reference during operation.
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 repre-
sentative before applying a PLC system to the above mentioned applications.
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 unex-
pected operation of the loads connected to the Unit. Any of the following opera-
tion may result in changes to memory status.
• Transferring I/O memory data from a Programming Device to the CPU Unit.
• Changing present values in memory with a Programming Device.
• Force-setting/-resetting bits with 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 net-
work.
Do not attempt to take any Unit apart while the power is being supplied. Doing so
may result in electric shock.
