1.7 FAIL/Memory End Output Function (/F1 option)
FAIL Output
When a failure occurs in the CPU of the FX100, the relay contact signal (1 signal) is
output. The relay is energized when the CPU is normal; it is de-energized when a CPU
failure occurs (de-energized on failure). Therefore, relay output is carried out even when
the power is turned OFF (even during a power failure) (see figure below). You cannot
change this behavior.
