10.3 Alarm Description Output Using PIO
In PIO patterns 0 to 3 (64 to 512-point positioning type), alarm information can be output using the ports for
completed position output signals (four bits of PM1 to PM8) so that when an alarm occurs, the nature of the
alarm can be identified on the PLC side.
Program the PLC so that whether a given output is a completed position number or alarm can be identified
based on the status of the alarm output signal (*ALM).
