In this case, the alarm remains on screen but the color is yellow (indicating alarm is no longer
active). Also note that the alarm acknowledgement indicator is ‘NO’. The alarm remains on
screen until the operator presses the acknowledgement key (%M10).
Alarms are displayed on the list in the order that they occur, with the first occurrence on top:
Use the optional scroll bar feature if there is a possibility of having more active alarms occurring
than there is room to display.
Historical Alarm List
The historical alarm type option in the Alarm List object displays only alarm messages in the
Alarm Database that have the Log field (History) enabled. Unlike the Real-Time option, alarm
messages remain on the list, even after the alarm has become inactive and/or the operator has
acknowledged the alarm.
Alarm messages in the Historical Alarm List are retained even when power is removed from the
HMC7000, and then reapplied. For this reason, the Historical Alarm List is primarily used to
provide a record of alarms that have occurred in the past.
