7.2 Limit comparators „LIMITCOM“
Limit comparators (threshold monitors, limit contacts)
can be used to monitor an input variable (process
value for the limit comparator) against a fixed limit
value or another variable w (setpoint value for the limit
comparator). When a limit value is exceeded, a signal
can be output or an internal controller function
initiated.
4 limit comparators are available.
Limit
comparator
functions
Limit comparators can have different switching
functions (lk1 to lk8). The switching differential HySt
(HYSTERES) can be set and is, in all cases,
symmetrical in relation to the limit value.
Hysteresis
function
The hysteresis function (symmetrical, asymmetrical)
defines the ranging of the switching differential
around the limit value (adjustment in the setup
program).
