Remarks

If for example both the IsHigh and IsHighHigh states need to be maintained as active at the same time this alarm is to be used.

A level alarm is commonly used to report when a limit is exceeded. It typically relates to an instrument – e.g. a temperature meter. The level alarm becomes active when the observed value is above a high limit or below a low limit.
