B.2 Audit Log and Alarm Event Log
The 'Audit Log' and 'Alarm Event Log' are used to display a list of events and alarms identified by icon, sequence number, date and
time.
The 'Audit Log' provides an historical log of system activity, the 'Alarm Event Log' provides an historical log of all alarm events in the
sequence in which they occurred.
When the number of entries in each log has reached 500, the oldest data is overwritten by the newest data. Entries are renumbered
so that the number of the oldest entry is always 00.
Both logs are accessible from the chart view and bar view.
