ElapsedActivetimeAlarmExt is a special-purpose alarm extension, especially for use as child of a BooleanPoint or BooleanWritable that has one or more DiscreteTotalizerExt extensions. It provides alarming on runtime (elapsed active time), using offNormal property errorLimit.
In the parent Boolean point, order the ElapsedActiveTimeAlarmExt slot below the DiscreteTotalizerExt slot
that it references. In the ElapsedActiveTimeAlarmExt’s Offnormal container, use the Discrete Totalizer Select property to reference the DiscreteTotalizerExt.
ElapsedActiveTimeAlarmExt is available in the Alarm folder of the kitControl palette, along with a ChangeOfStateCountAlarmExt (for COS-based alarms). You can use both extensions to reference the same DiscreteTotalizerExt.
