DALI addressing

This chapter covers gateway addressing so as to provide a better appreciation of the gateway's
functionality.
To control DALI devices individually or in groups, DALI commissioning (configuration) is required. This
involves assigning DALI addresses and/or groups to DALI devices.
The gateway executes automatic DALI addressing if the Enable automatic DALI addressing parameter is
set to Yes in the X DALI configuration parameter window. The gateway automatically detects the
connected DALI equipment and assigns an address in ascending order if the device does not have one.
If automatic DALI addressing is not allowed, there are three alternative options for implementing
addressing with the DALI gateway:
•
i-bus
•
Press and hold (> 5 seconds) the
•
Trigger DALI addressing group object
In order to implement DALI addressing, the gateway autonomously and automatically checks the DALI
devices connected to the DALI output. If it detects equipment with a DALI interface that has not been
assigned a defined DALI address (default delivery state, DALI short address 255), it automatically assigns
one. The detected DALI device will be assigned the first free DALI address (0 to 63) on the output. If no
DALI devices have yet been detected, it is assigned the first DALI address, 0. The second device is
assigned DALI address 1, and so on. The sequence in which the DALI master, e.g. the gateway, finds a
device with a DALI interface cannot be influenced. If the connected DALI device already has a DALI
address, e.g. an exchange device from another system, it will not be changed.
If the new DALI device has a DALI address which is already in use on the output, one of the two 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 output may receive a new address.
To control groups, the connected DALI devices must be assigned to a group. The external i-bus
which is independent of ETS, is used for this.
