When the LINK LED turns off
Check item
Are Ethernet cables normal?
Do the switching hub and other stations in the system normally
operate?
If link-up processing is repeated due to a condition of a device on the line, it may take a longer time for the
LINK LED to turn on.
This phenomenon may be eliminated by changing the module PORT into which the Ethernet cable is
connected (example: PORT1  PORT2).
When the SAFETY LED turns off
Check item
Have parameters been set to the safety remote I/O module?
Has the safety communication setting been configured?
Has the safety module validation been performed?
Has the safety station interlock of the Safety CPU been canceled?
Has any error occurred?
Is the operating ambient temperature within the specified range?
