ChangeOfStateCountAlarmExt 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 COS (change of state) counts, using offNormal property errorLimit.
In the parent Boolean point, order the ChangeOfStateCountAlarmExt slot below the DiscreteTotalizerExt slot
that it references. In the ChangeOfStateCountAlarmExt’s Offnormal container, use the Discrete Totalizer Select property to reference the DiscreteTotalizerExt.
ChangeOfStateCountAlarmExt is available in the Alarm folder of the kitControl palette, along with a ElapsedActiveTimeAlarmExt (for runtime-based alarms). You can use both extensions to reference the same DiscreteTotalizerExt.
