Hi all,
I have a project with several DNPR I/ODevices.
During tests i notice that Citect retain alarm status on the following scenario:
1 - I switch down a circuit breaker on the electrical board,
2 - The signal appears in Citect, (animation symbol and alarm list the signal = TRUE)
3 - I force a power failure on the electric board, and Citect detects the communication break with this plc (The PLC has no power)
4 - I switch the same circuit breaker back up.
5 - I restore power back on, and wait until communication is establish between Citect and PLC.
6 - In the animation the signal is False and in the alarm the signal is TRUE (Tag=0 and AlarmTag.On=1)
Has anyone had this problem?
Best Regards
