3 Counter value = comparison value ®
output is set and hysteresis activated
4 Output is reset for leaving hysteresis range and counter value > comparison value
5 Counter value = comparison value ®
output is set and hysteresis activated
6 Counter value = comparison value and hysteresis
active ® output remains set
7 Leave hysteresis range and counter value > comparison value ® output is reset
With reaching the comparison condition the hysteresis
gets active. At active hysteresis
the comparison result remains unchanged until the counter value leaves the set hyste-
resis range. After leaving the hysteresis range a new hysteresis is only activated with
again reaching the comparison conditions.
1 Counter value = comparison value ®
pulse of the parameterized pulse duration is put
out, the hysteresis is activated and the counting direction stored
2 Leaving the hysteresis range contrary to the stored counting direction ®
pulse of the
parameterized pulse duration is put out, the hysteresis is de-activated
3 Counter value = comparison value ®
pulse of the parameterized pulse duration is put
out, the hysteresis is activated and the counting direction stored
4 Leaving the hysteresis range without changing counting direction ® hysteresis is de-
activated
5 Counter value = comparison value ®
pulse of the parameterized pulse duration is put
out, the hysteresis is activated and the counting direction stored
6 Counter value = comparison value and hysteresis
active ® no pulse
7 Leaving the hysteresis range contrary to the stored counting direction ®
pulse of the
parameterized pulse duration is put out, the hysteresis is de-activated
With reaching the comparison condition the hysteresis
gets active and a pulse of the par-
ameterized duration is put out. As long as the counter value is within the hysteresis
range, no other pulse is put out. With activating the hysteresis the counting direction is
stored in the module. If the counter value leaves the hysteresis range
contrary to the
stored counting direction, a pulse of the parameterized duration is put out. Leaving the
hysteresis range without direction change, no pulse is put out.

ison value with pulse
