Leaving the hysteresis range contrary to the stored counting direction
→
pulse of the
parameterized duration is put out, the hysteresis is de-activated
With reaching the comparison condition the hysteresis gets active and a
pulse of the parameterized 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 CPU. 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.
