AlarmClear

Clears an acknowledged (and off) alarm from the active alarm list. You can clear the alarm where the cursor is positioned, one or more alarm lists on the active page, a whole category of alarms, or alarms of a particular priority.

If you set the [Alarm]AckHold parameter to 1, alarms that go off and have been acknowledged are not removed from the active list until this function is called.

This argument is not required where the mode is 2 and the value is 255 (hardware alarm category).
