800xA Alarm Event Architecture: Status OK system Alarm
i have persistent system alarm Status OK after OLU session which can't be acknowledged or removed and ABB Support_Line advised to reset the controller to clear it but it is not possible even during shutdown time as the download will be init and returns to initial values. i want to overflow the controller Alarm?event Buffer which can store queue of 300 (default) messages and kick out the stale alarms from the buffer if i generate more than 300 Alarms conditions simultaneously, i tried but didn't generate system simple event of overflow despite i generated more than 500 alarms.
in controller settings
AE Event subscription queue size = 200-3000

I believe the support line recommendation to reset the controller doesn't mean to do an init download.
You can reset the controller and do a cold download to retain all cold retain parameters.
