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. The Limit can be changed by users with 127 security Level in run-time VIEW. This field is for ANALOG tags and parameters only.
