ABB i-bus KNX
Commissioning
With the option Yes: via object "Switch/Status", the following parameter appears:
Status response of brightness value
Options:
The parameter defines how the current status of the brightness value of the output (the lighting) is sent on
the KNX.

No: The brightness value is not actively sent on the KNX.

Yes: via object "Brightness value/Status": The brightness value is sent on the KNX via the
communication object Brightness value/Status.

Yes: via separate object "Status Brightness value": An additional Status Brightness value
communication object for the status message is enabled. This option is not available if the lighting
group is parameterized as a Light controller or Slave.

Note
This status message relates to all connected devices of the lighting group.
With a change of the parameterization or after a subsequent switching of the status object, the
assignment of the group addresses already allocated to the communication object Switch is lost
and needs to be reprogrammed.
If the communication object Switch/Status is used for switching and status feedback, particular
care must be taken with the read and write properties (flags) of the communication objects.
For further information see:
Unwanted switching states may result for lighting group devices due to differing status messages
within a lighting group. For this reason, only one communication object should report the status
in a lighting group with several Switch/Status communication objects, in order to eliminate mutual
interference of devices as a result of differing status messages.

status is requested via the communication object Request status values.
