Limit alarm
Monitors when the values of interest are reached for variables relating to physical quantities. Activates when the value of the monitored variable reaches one or more limits of interest. When several limits of interest are reached consecutively, the alarm signals only the last limit reached (exclusive) or all the limits reached (non-exclusive)
