3.1.3 AdaptiveAlarm

Alarm for which the setpoint or limits are changed by an algorithm.

Note 1

Note 1 to entry: AdaptiveAlarms are alarms that are adjusted automatically by algorithms. These algorithms might detect conditions in a plant and change setpoints or limits to keep alarms from occurring. These changes occur, in many cases, without Operator interactions.
