Emptying the alarm buffer: Alarm history
The alarm history traces up to 56 alarms.
The alarm history only takes alarms that have been removed from the alarm buffer. If the
alarm buffer is completely filled - and an additional alarm occurs - then the converter shifts all
alarms that have been removed from the alarm buffer into the alarm history. In the alarm
history, alarms are also sorted according to the "alarm time received", however, when
compared to the alarm buffer, in the inverse sequence:
● The youngest alarm is in index 8
● The second youngest alarm is in index 9
● etc.
Figure 11-4 Shifting alarms that have been removed into the alarm history
Any alarms that have not been removed remain in the alarm buffer. The converter sorts the
alarms and closes gaps between the alarms.
