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.
6.13 Counter - Diagnostic and interrupt
The parametrization allows you to define the following trigger for a process interrupt that
may initialize a diagnostic interrupt:
n
Status changes at an input
n
Status changes at the HW-gate
n
Over- respectively underflow or reaching an end value
n
Reaching a comparison value
Effect at pulse at compar-
ison value with pulse
duration not zero
