Process Simple Events are getting deleted/erased
Hi All,
We are facing an unusual case that only some of the specific Process Simple Events are getting deleted/erased. For example, Some load shedding events has generated during one load shedding operation yesterday. that time it was available in the event list, however today when we saw the event list, only that particular events has been missing from the list, rest of the Process Condition or Process Simple Events (before & after this event) are available in the list.
Does any one faced such issue earlier.

Hello,
Look at the band set for these category of events in alarm manager and event storage.
Always set low for system and high band for process.
Hence once crosses the limit events will go out from list erroneously (not in fifo).

Theoretically, the Event Storage service is strictly overwriting old events with new. Hence, the ”middle” of three consecutive events of the same category should not be overwritten.
Are you sure you see events of the same category as the missing one behind the time of the missing one?
Filter problem? Configuration changed (eg object renamed, downloaded, etc)?
Is this problem reproducible?
Please have a support case filed with your regional ABB service representative.
In any case you might consider extending the storage of Process Simple Events up to 50.000 by making two adjustments: five double the file size and set number of events to 50.000.
