Enabling/Disabling Minor Deviation Alarms

The .AlarmMinDevEnabled and .AlarmMinDevDisabled dotfields enable or disable minor deviation alarms for a tag or alarm group based upon their respective values. The minor deviation alarm states associated with both dotfields are the inverse of each other. In the case of .AlarmMinDevEnabled, a value of 1 enables minor deviation alarms for a tag or alarm group. An .AlarmMinDevDisabled value of 1 disables minor deviation alarms for a tag or alarm group.

When either dotfield enables minor deviation alarms for an alarm group, all tags that belong to the group have minor deviation alarms enabled. When either dotfield disables minor deviation alarms, all minor deviation alarms are ignored. The minor deviation alarms are not stored in alarm memory, nor are they written to disk.
