The diagnose files of WinCC. Hope this is useful.

Hi Yoga

If I understood you well, your problem is filter inAlarm Logging.

During Runtime you can display or hide acknowledge messages via Selection button.

On the other hand, remember that Online Messages refer to Active Alarms only, soif you acknowledge an active alarm (value is still in 1), this alarms will be shown as activated and acknowledgein the list.If this alarmis not active anymore (value 0), as soon as you acknowledge it, it will disapper from the list!
InShort or Long Term archive view (these name are from old WinCC versions!), you cansee all acknowledgement.

But remember thatWinCC acknowledges messages automatically beforethey areactivated. For example: alarm has value 0 (deactivated), goes to 1 (activated), back to0 and once more to 1. Before the second activation (value 1),WinCCwill automatically acknowledge this message 1ms before the new activation.
For this reason,I think that most people only enable acknowledge message to be displayed only inOnline message view.

Is this what you needed?
