C) Function mode for comparison value with non−zero pulse duration
When the comparison condition is met, hysteresis becomes active and a pulse of the
parameterised duration is released. As long as the count value is within the hysteresis
range, no further pulse is released. With activation of the hysteresis, the counting direction
is stored within the module. If the count value exits the hysteresis range in opposition to
the counting direction stored, a pulse of the parameterised duration is released. When the
hysteresis range is exited without a change in direction, no pulse is released.

 Count value = comparison value ®Pulse of the parameterised period is output, hysteresis is
activated, and the counting direction is stored
‚ Exiting of the hysteresis range against the counting direction stored ® Pulse of the
parameterised pulse duration is output and hysteresis is deactivated
ƒ Count value = comparison value ®Pulse of the parameterised pulse duration is output,
hysteresis is activated, and the counting direction is stored
„ Hysteresis range is exited without change of the counting direction ® Hysteresis is
deactivated
Count value = comparison value ®Pulse of the parameterised pulse duration is output,
