Now the situation is as follows: when a PLC creates an alarm, the alarm appears in WinCC with a color red, and an SMS is also sent. When the alarm resolves itself in the PLC, the alarm message changes from red to green and must be acknowledged to remove it from the screen. Only if the alarm is generated again in the meantime, it will change from green status to red status and another SMS will be sent. is there a possibility in WinCC that when an alarm is received, it will receive the status red and remain there until it is acknowledged, even if the PLC finds that the alarm is no longer present. I have already played with the message types "came in" "went out" but unfortunately this does not give the desired result.

Which PLC sends the Alarms (type)? Do you show the alarm class in RT in the Alarm view? Check if you set up correct colurs in Alarm Logging editor for this alarm class Bye Murof

These are all generated at bit level under different "message types". The different types also have different colors. We use a web viewer to view and respond to alarms. So what we want is that when an alarm is generated in a PLC, it enters our wincc system. When the PLC finds that the alarm is no longer active, it should simply remain in Wincc (no went out). If the PLC then generates it again, it should not be re-entered (because it has not yet been confirmed by WinCC). Our Wincc is only a readout of the PLCs, so we do not write bits to the PLC to confirm alarms, we only monitor the PLCs, but we want to create peace in our fault reports.

But these event changes you will only see in historical data, if you only use the pending alarms view, you will not see the systemachknoledgement Bye Murof

I will therefore close this topic Murof Hello JoeyDR Wich descrete alarms (bit triggered) this is not possibel directly because if the trigger bit changes every time WinCC reacts to the state change (1->incoming-> 0 outgoing-> 1 -> systemacknolegement/incoming....)
