External Alarm Acknowledge 800xA 6.0.3
I tried to externally acknowledge an alarm in 800xA v6.0.3 (on a ControllerPID in the PCDeviceLib) by connecting a variable to the InteractionPar.AlarmAck. Although this variable pulses every 10 seconds for 1 second, the alarm remains.
Do I need to to do additional configuration compared to standard acknowledgement via the faceplate. Acknowledging on the faceplate is possible.
An AC 800M AlarmCond block accept acknowledge from 61131 code (your program). Can’t tell why PCDL type gives you trouble.
Try creating a naked AlarmCond in some test location and notice what takes place as you toggle the AckCond input pin when there is an unacknowledged alarm. In theory, the same should probably take place with the PCDL object.
Ask vendor of PCDL for help if you can’t get it to work.
