stops after all alarms are released (if no other relay output conditions are met).
FAIL
When a failure occurs in the GX/GP CPU, a relay contact signal (1 signal) is output. The
relay is energized when the CPU is normal and is de-energized when a CPU error occurs.
Therefore, relay output is carried out also when the power is off (including a power failure).
You cannot change this behavior.
