Alarm acknowledgment
If an alarm appears in the alarm summary or some other alarm display,
an operator can acknowledge the alarm. Acknowledging an alarm does
not correct the condition causing the alarm, but indicates that an
operator is aware of the alarm.
A tag, not an alarm, is acknowledged. A single tag might have caused
several alarms. For example, a tag representing temperature might
have triggered Warm, Hot, and Overheat alarms by the time it is
acknowledged. The tag could also have gone in and out of alarm
several times before being acknowledged.
One acknowledgment is all that is required for all previous and current
alarms for a tag, so alarm log files often show fewer acknowledgments
than alarms.
