4.
Power on the power supply of the safety remote I/O module.

Unit test begins.
The RUN LED flashes during the unit test.
6.
The RUN LED turns on when the unit test is completed.
• If the test is completed normally, the ERR. LED does not turn on, but remains off.
• If the test is completed with an error, the ERR. LED turns on. If the test is completed with an error, replace the Ethernet
cable and run the test again. If the test fails again, it may be due to a hardware failure in the safety remote I/O module.

Precautions
If the safety remote I/O module is connected to the network while IP address setting switch (x16) and IP address setting
switch (x1) are set to F, data link may not be properly performed on safety remote I/O modules of other stations.
Set appropriate values both for IP address setting switch (x16) and IP address setting switch (x1), and connect the safety
remote I/O module to the network.
