How Do You Configure Alarms for a Tag?
While editing a tag, click the Enable Alarms checkbox. Alarms are
generated depending on the value or state of a tag. The alarms based on
value vary with the tag data type. But for any tag, if the status is bad, a
Bad Status alarm is generated. By default, Bad Status Alarm is enabled
and has the highest priority (15). You can change this selection from the
Alarms tab of the Tag Configuration Editor, shown in Figure 3-11.
Analog Tags
Analog tags have four alarm levels: HI_HI, HI, LO, and LO_LO. By
providing separate alarm levels, you can provide more information about
the nature of the alarm condition.

Alarms are calculated after scaling is performed. Alarm levels are
expressed in engineering units.
