DALI group control

The ABB i-bus
64 DALI devices on a DALI output and making them available via 16 lighting groups on the KNX.
The advantage of this concept is that, at any time, the 64 DALI devices can be assigned to a lighting group
individually and without a change to the installation. As a result, maximum flexibility is retained until final
acceptance or when the room usage changes. At the same time, the programming effort in ETS is
considerably reduced by the assignment of 64 individual devices to 16 lighting grouplighting groups.
Furthermore, the programming effort can also be reduced using the copy and exchange function of lighting
groups in the DLR/S.
The Light Sensors LF/U 2.1 required for constant light control can be assigned to one of the first 8 DALI
lighting groups via ETS. The detected brightness is used in the DALI Light Controller for the 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/S or indirectly via the communication objects on the KNX.
For every lighting group, the DALI Lighting Controller can send the status of the lighting group on the KNX.
Furthermore, it is possible to poll the fault status of every single DALI device individually via the KNX.
Coded telegrams are available for this purpose.
