Clearing events from the event history:
The controller can store up to a maximum of 1000 events in its queue. The default queue
size is 50 events and is configured in the SE (System Event) block of the database. You
can configure what goes in to the queue. By default, the following are entered in the event
list: (see the next figure)
1. Informational events
2. Block state changes
3. Process alarms
4. Diagnostic alarms
5. Notification message events
6. System Event events

You can configure process alarms and diagnostic alarms associated with each block to be
entered in to the event list on an individual basis.
