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.
If the alarm history is filled up to index 63, each time a new alarm is accepted in the alarm
history, the oldest alarm is deleted.
