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.

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
