This manual is intended for the following personnel, who must also have
knowledge 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 specifica-
tions 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 systems, vehicles, combustion systems, medical equipment, amuse-
ment machines, safety equipment, and other systems, machines, and equip-
ment 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
sufficient for the systems, machines, and equipment, and be sure to provide
the systems, machines, and equipment with double safety mechanisms.
This manual provides information for installing and operating the DeviceNet
Configurator. Be sure to read this manual before operation and keep this man-
ual close at hand for reference during operation.
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.
Never attempt to disassemble a Board or Card or touch the inside of a Board
or Card while power is being supplied. Doing so may result in serious electri-
cal shock or electrocution.
Provide safety measures in external circuits, i.e., not in the Programmable
Controller (CPU Unit including associated Units; referred to as "PLC"), in
order to ensure safety in the system if an abnormality occurs due to malfunc-
tion 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-
