WARNING
● In the case of a communication failure in the network, the status of the error station will be as follows:
(1) All inputs from remote I/O stations are turned off.
(2) All outputs from remote I/O stations are turned off.
Check the communication status information and configure an interlock circuit in the program to
ensure that the entire system will operate safely. Failure to do so may result in an accident due to an
incorrect output or malfunction.
● Outputs may remain on or off due to a failure of the CC-Link IE Field Network remote I/O module (with
safety functions). Configure an external circuit for monitoring output signals that could cause a serious
accident.
CAUTION
● Do not install the wiring for external devices or communication cables together with the main circuit
lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result
in malfunction due to noise.
● When selecting external devices to be connected to the CC-Link IE Field Network remote I/O module
(with safety functions), consider the maximum inrush current described in the CC-Link IE Field
Network Remote I/O Module (With Safety Functions) User's Manual.
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing a
safety programmable controller. Failure to do so may result in electric shock or cause the module to
fail or malfunction.
