Acknowledge an alarm
When you acknowledge an alarm it does not correct the condition causing the alarm,
but indicates that an operator is aware of the alarm.
A single tag might have several alarm conditions In Alarm. Each alarm condition must
be acknowledged separately. For example, a tag that monitors a temperature might
trigger HI and HIHI alarm conditions by the time it is acknowledged. The alarm could
also go into and out of alarm several times before it is acknowledged.
Previous occurrences of an alarm that have gone Out of Alarm and then back In Alarm
cannot be acknowledged. These old occurrences are called “out of scope” and are
displayed in the alarm list with a different icon. When the most recent occurrence of
an alarm is acknowledged, previous occurrences are removed from the alarm list.
To acknowledge the selected alarm:
In the Alarm and Event Summary event list, do one of the following:
„ Select the alarms you want to acknowledge, and then click the Acknowledge
selected alarm button, shown at left.
„ Select the alarms you want to acknowledge, right-click the selected alarms, and
then click Ack on the context menu.
