Enable/disable HiHi alarms

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

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