At run time, system Alarms can be viewed on an E3Alarm.

E3Alarm at run time

Among the Alarms that meet the configured Filters, active or unacknowledged ones are displayed on an E3Alarm. Usually, these Alarms can be divided in the following cases:

•If Alarm Source's Need Ack option is set to False, this Alarm is considered acknowledged since its activation, with no need to acknowledge it. In this case, this Alarm is visible until it leaves its active condition

•If Alarm Source's Need Ack option is set to True, users can acknowledge this Alarm either before or after its variable leaves this Alarm's condition. In both cases, this Alarm only leaves E3Alarm list when both conditions are met

The BannerMode property, when set to True, allows viewing only a single alarm message on an E3Alarm object. The displayed message depends on the configuration performed on the Sorting tab.
