The switching position of the DIP switch has priority over the communications software!
If the values of the sealing function (CUTOFF) or the correction characteristic (CHARACT) are changed
via the communication software, the corresponding function must be active (DIP switch set to ON).
The effective direction of the set-point value (DIR.CMD) can be changed via the Dip switches.
