2.4 Functions

All of the channels have identical functions (have a look at the functional overview). The numbers of
channels depends to the hardware design, which can have 2, 4, 8, 12 or 16 channels. The
identification is standardly in consecutive alphabetic order.
There are 3 different states for every channel possible:

The channel has no function. So there are no communication objects for this channel shown.

If the channel is chosen as switch, there will be different parameterization options for
configuring the switching process.

Now, the channel can become a staircase light function. This function causes an automatic
switch off of the channel after an adjusted time.
