Enable/disable discrete alarms

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

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