AlarmCond Alarm no message after 4 Events if unack
When I have an Alarm signal that toggles between Normal and not Normal state, then the alarm message "Inactive" and "New" in the event list appears only 4 times then I have to acknowledge the alarm to get these messages again in the event list. If the alarm keeps unacknowledge there are no message any more in the event list.
I use the AlarmCond Function Block out of the AlarmEventLib

I assume you are using AC800M Controllers...
This behavior is configured with the setting "AE Limit auto disable" on the Controller which by default is "3".
