10.3 Alarm Description Output Using PIO
So that the PLC can recognize the nature of each alarm that has generated, alarm description is output
using the ports for completed position output signals (PM1 to PM8).
Configure the system in such a way that the PLC can determine whether the output is a completed
position number or alarm description based on the ON/OFF status of the alarm output signal (*ALM).
