4.2.31.6        HH Alarm Limit

High-High Alarm Limit.  Alarming is used to notify operators and users of abnormal conditions in runtime VIEW.  The tag must change ABOVE the Hi-Hi Alarm Limit to be considered in the alarm state. The Speed Limit on the Highway is an example of a High-High Alarm. The High-High alarm is in engineering units of the tag (not percent).  This is similar to the High Alarm.  The High-High Alarm Limit must be greater than the High Alarm and Low Alarm Limits. Like any tag field, the Limit can be changed by users with 127 security level in run-time VIEW. This field is for ANALOG tags and parameters only.

Range:                    -99,999,999,999 to 99,999,999,999 (but greater than ALMLO & ALMHI)
Units:                     same as Tag
Field Type:            Analog
