4.8.4.3 Step switch simply
The binary-coded step controller is identical in its functionality to the normal step controller as
described in
4.8.4.1 Step switch bit-coded
. Only the output stage has a different structure. Each time
the stage is increased, the previous and the new one are switched on, which is also clear from the
communication objects:

4.8.4.4 Step switch as Byte
The “Step switch as Byte” contains of a steady output value. Up to 4 levels can be defined with an
absolute value (0-100%). The fifth level is the off-state, which sends the value 0%.
The following figure shows an example for the output of the step switch as Byte:
