ABB i-bus KNX
Commissioning
DALI device will automatically be assigned to
lighting group 8,
if it is not assigned
to any other group.
Options:

no: Lighting group 8 is available as a normal lighting group in the DLR/A. It has the same properties
and functions as the lighting groups 1 to 7.

yes: the DLR/A automatically initially assigns all DALI devices to lighting group 8. If the DALI device is
assigned to another lighting group, this device will be removed from lighting group 8. Using this
procedure, it is possible to commonly control all DALI devices via the DALI output in the KNX without
any manual DALI group assignment.
Note
Lighting group 8 is only used internally by the DLR/A. The communication objects of lighting group 8 are
still available and can be used for example, to make non-assigned DALI devices visible, by switching on
and off without using the Software Tool.
In order to control the lamps on the DLR/A via the KNX, they must be assigned to a lighting group. The
assignment occurs using the Software-Tool.
All lighting groups are indicated on the KNX. Control of the individual 64 DALI devices via the KNX is
not possible with the DLR/A.
All DALI devices can be controlled via the communication objects DALI output, if they are already
assigned to any lighting group. If this is not the case, it is possible to assign DALI devices, which are not
assigned to lighting group 8, using the parameters described here.
This is undertaken automatically by the DLR/A. If a lighting group is assigned to another lighting group,
the DLR/A removes it again from group 8.
The DLR/A does not automatically use a DALI broadcast telegram for the telegrams that are received
via the communication object of output A. In dependence on different properties of the DALI devices,
e.g. minimum and maximum dimming values (dimming thresholds), several DALI group telegrams may
be utilized. It is therefore recommended that as many DALI devices as possible with the same physical
properties are compiled into a lighting group.
