1.9 FAIL/Status Output Function (/F1 Option)
FAIL Output
When a failure occurs in the FX CPU, the FX generates a relay contact signal (1 signal).
The relay is energized when the CPU is normal and de-energizes when a CPU failure
occurs. Therefore, relay output is carried out also when the power is turned OFF (including
a power failure). You cannot change this behavior.

Status Output

when the status occurs. You cannot change this behavior.
