Control telegram and status with a communication object

The DLR/S allows the option of simultaneously feeding back the status (Switch/Status, Brightness
value/Status) via the control communication objects (Switch, Brightness value).
Here, it is important to observe that only one DALI device may feed back the status in a KNX group with
several control communication objects. The DALI device should be parameterized as the broadcaster.
Otherwise, it is possible that there is continuous switching over and back of the controller and the status.
Example
The lamps to be switched are located in the three lighting groups (group 1, 2 and 3), which are
commonly controlled via a KNX group. The status of the lighting group is to be sent via the KNX. The
following assignments result:
The state of group 1 is used as the status for the entire lighting group.
Communication object no.
