4.4.5.3 Step switch simple

The functionality of the step switch simple is identical to that of the normal step switch as
described under "

4.4.5.1

Step switch bit coded

". Only the output level is constructed

differently. With each increase of the step, the previous and the new one is switched on, which is
also clear from the communication objects:
