Aggregated alarm information

Alarm aggregation lets you see all the active severity 1 through 4 alarms within an area object, as well as all the active alarms on all the area's contained objects, including contained area objects. This provides an efficient way at runtime to identify if there are any active alarms (in the InAlarm state), and the location and status of alarms, for example, unacknowledged and unacknowledged - return to normal. This makes it possible to follow a trail from one level to the next to find the underlying cause of a complex object’s alarms. Severity 5 alarms, if configured, are not aggregated.

To obtain aggregated alarm severity status information:

1. Map alarm severity levels to priority ranges. For more information, see Configure priority ranges for alarm historization, mapping, and shelving .

2. Configure alarms on objects. For more information, see Configure alarms.

3. Enable alarm aggregation by Area. For more information, see Configure alarm state aggregation

4. View aggregated alarm status information by means of runtime clients and applications. For more information, see Monitor alarm state information at runtime.
