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.

So you may react to asynchronous events, there is the possibility to activate a process
interrupt. A process interrupt interrupts the linear program sequence and jumps
depending on the master system to a corresponding Interrupt routine. Here you can react
to the process interrupt accordingly.
With CANopen the process interrupt data a transferred via an emergency telegram.
Operating with CPU, PROFIBUS and PROFINET the process interrupt data were trans-
ferred via diagnostics telegram.
