When the life detection function of the Q61P-D is faulty, the LIFE OUT terminal repeats on and off for three times when the
module is started.
Depending on the system, this behavior (on and off) of the LIFE OUT terminal may not be obtained to the input module due
to delay of the sequence program start after the Q61P-D has started.
In this program example, M11 turns on even though the life detection function is faulty when powered on since the remaining
life is regarded as one year.
Device
X0F Resets the life monitoring processing
Turns on when the remaining life of the Q61P-D is one
