Limit comparators

Limit comparators (limit monitors, limit contacts) can be used to monitor an input
variable (limit comparator process value) against a fixed limit or another variable
(limit comparator setpoint). When a limit is exceeded, a signal can be output or an
internal controller function initiated.
