C, R, W, T
This communication object is enabled if, in the
Parameter window Status - Central
, page 61, the parameter Status
response of brightness value for this output is set with the option Yes: via object "Brightness value/Status".
This communication object has the same functions and properties as the communication object Brightness value. The
status is additionally fed back. With differing brightness values of the DALI devices, the average brightness is displayed.
Different brightness values can only occur if overlapping lighting groups (one device is assigned to several groups) are
parameterized. Overlapping lighting groups should not be used due to the complexity of a light controller. However, they
are not prohibited by the DLR/S, but cannot be supported by parameters.
The parameterization is implemented in the parameter window Status - Central.
Telegram value:
0 = OFF, or minimum dimming threshold
…
255 = 100 %
Note
If several groups are assigned to the communication object Brightness value/Status, the status address
should be set as the sending address. In a KNX group with several status messages, it is useful to allow
just a single group member to feedback the status.

C, R, T
This communication object is enabled if, in the
Parameter window Status - Central
, page 61, the parameter Status
response of brightness value of this output is parameterized with the option Yes: via separate object " Brightness
value/Status".
Telegram value:
0 = OFF
…
255 = 100 %, max. brightness value
This communication object reports the current brightness value of the DALI device. The value of the communication object
updates itself during a dimming process, scene or staircase lighting time curve.
It is possible to parameterize if the status is sent on After a change and/or After request.
