Automatic DALI addressing

To help you appreciate the functionality of the DALI Light Controller better, this chapter describes the
addressing of the DLR/S.
DALI commissioning (configuration) is necessary for the DALI Light Controller. The connected DALI
devices are automatically detected and an address in ascending order is assigned if no DALI address is
available.
Note
The DLR/A does not perform automatic DALI addressing for DALI devices if, in the
General, page 43, the parameter Enable automatic DALI addressing has been set to No.
As soon as the light controller operating voltage has been applied to the DLR/S, it automatically and
independently checks the DALI devices connected to the DALI output. This process is also started after a
download or KNX voltage recovery or light controller operating voltage recovery and may take about
60 seconds, depending on the number of connected DALI devices. If equipment with a DALI interface is
detected, which does not possess a defined DALI address (default delivery state, DALI short address 255),
the DALI Light Controller will automatically assign a DALI address. The detected DALI device will be
assigned the first free DALI address (0 to 63) in the DLR/S. If no DALI devices have yet been detected, it
is assigned with the first DALI address: 0. The second device is assigned with DALI address 1.
The sequence in which the DALI master, e.g. the DLR/S, finds a device with DALI interface cannot be
influenced. If the connected DALI device already has a DALI address, e.g. exchange device from another
system, it will not be changed.
If the new DALI device has a DALI address, which is used in the DLR/S, one of both DALI devices with the
same address will be assigned a new and unused DALI address. This means that the old DALI device,
which is already connected to the DLR/S, will receive a new address.
With the DLR/S, you can now control the connected DALI devices with the DALI output communication
objects via the KNX without additional DALI group assignment.
The connected DALI devices must be assigned to a lighting group to control individual lighting groups.
The assignment is implemented with the external ETS independent Software Tool.
