Hysteresis counter 1
The hysteresis for instance serves to avoid frequent
switching operations of the output and/or triggering of
the alarm when the count value is within the range of the
comparison value. For the hysteresis you can select a
range between 0 and 255. With the settings 0 and 1 the
hysteresis is switched off.
The hysteresis has an effect on the zero crossing,
comparison, overflow/underflow.
