AC500-eCo PM554 - Get Active Alarms?
I'm using a PM554-ETH PLC, and I would like to write to an internal memory bit whenever the PLC has an ACTIVE alarm. Is this possible? If so, how do I do it?
I have found the DIAG_GET function, but that only reads an unread alarm once. It does not let you know if the alarm is still active or not.
