DALI group control

The ABB i-bus
DALI devices on a DALI output and making them available via 8 lighting groups on the KNX. The
advantage of this concept is that at any time the 64 DALI devices can be assigned individually and without
a change to the installation to a lighting group. As a result, maximum flexibility is retained until final
acceptance or when a change is required later to the room usage. At the same time, the programming
effort in ETS is considerably reduced by the assignment of 64 individual devices into 8 lighting groups.
Furthermore, the programming effort can also be reduced using the copy and exchange function of lighting
groups in the DLR/A.
The Light Sensor LF/U 2.1 required for constant lighting control can be assigned to one of the first 4 DALI
lighting groups via ETS. The registered brightness values are used in the DALI Light Controller for
calculation of the control values. The calculated control value is sent directly, without any additional KNX
bus communication, to the assigned DALI lighting group. Using master/slave operation, further lighting
groups can be integrated directly in the DLR/A or indirectly via the communication objects on the KNX.
For every lighting group, the DALI Light Controller can send the status of the lighting group on the KNX.
Furthermore, it is possible to read the fault status of every single DALI device individually via the KNX.
Coded telegrams are available for this purpose.
