Support the Alarm information model and the notification mechanisms about the Alarm state. It also includes the management of transitions between various states by an alarm, such as shelving, acknowledgement, confirmation and the addition of comments.
The Alarm model builds on the condition model.
Indicate areas of the process that require immediate attention. Examples are:
- safety limits of equipment
- event detection, and
- abnormal situations.
In addition to operators, other client applications may collect and record alarm information for later audit or correlation with other historical data.
