The Alarm folder in the kitControl palette contains 3 special-purpose alarm extensions, two of which are for Boolean type points that also have one or more DiscreteTotalizerExt extensions, as follows:

They provide alarm capability based upon COS count and runtime (elapsed active time). If using either (or both) extensions above, in the parent Boolean point (BooleanPoint, BooleanWritable), you must add (order) them under the corresponding DiscreteTotalizerExt.

Also, a LoopAlarmExt is available. This extension provides a “sliding limit” type alarm for a LoopPoint, based upon control deviation from setpoint.

Finally, an AlarmCountToRelay component provides configurable monitoring of the number of alarms (alarm count) of a linked Alarm Class component, and features a timed boolean “relay” output.

Starting in AX-3.6, a new alarm extension is available in the “Extensions” folder of the alarm palette: a StringChangeOfValueExt. See the User Guide section “alarm-StringChangeOfValueExt” for details.
