Status Switch
Group x
1 bit
DPT 1.001
C, R, T
This communication object is enabled if, in the
, page 77, the parameter Status response of
switching state is parameterized with Yes: via separate object "Switch/Status".
Telegram value:
0 = OFF and status: Lighting group switched off
1 = ON and status: Lighting group switched on
The value of the communication object directly shows the current switch state of the lighting group x. The status can be
sent After a change and/or After request.
32
Brightness value
Group x
1 bit
DPT 5.001
C, W
A defined brightness value for the corresponding lighting group x is received via this communication object. Any elapsing
burn-in time currently active has a higher priority, so that under certain circumstances individual devices can only assume a
brightness of 100 % or OFF.
In the
, page 67, you can parameterize whether to jump to this value or dim to it using a
dimming speed.
If the brightness values are above or below the max. or min. dimming values (dimming thresholds), the respective dimming
threshold is set.
Telegram value:
0 = OFF, or min. dimming threshold, if parameterized
…
255 = 100 %
It is possible to parameterize that the status of the brightness value is fed back via the communication object Brightness
value/Status. Normally, a separate communication object Status brightness value is used. This can be enabled in the
, page 77.

Brightness value/Status
Group x
1 bit
DPT 5.001
C, R, W, T
This communication object is enabled if, in the
, page 77, the parameter Status response of
brightness value is set with the Yes: via object "Brightness value/Status" option.
This communication object has the same functions and characteristics as the communication object Brightness value. The
status is additionally fed back.
Additionally, the value of the communication object is also updated if this is not sent on the KNX.
Telegram value:
0 = OFF, or minimum dimming threshold
…
255 = 100 %
Note
If several KNX group addresses 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.
