Hysteresis function
The hysteresis function switches the output as soon as the switching point "SP" is reached. When the
release point "rSP" is reached, the output switches again.
The hysteresis function distinguishes between N/C and N/O contacts.
Switching requirement: Switching point "SP" ≥ Release point "rSP"
