Several devices can be assigned to the groups 1...16. Only one device can be assigned to each of
the groups 17...32.
DALI devices that are assigned several groups will always adjust to the state adjusted last via one of
the assigned groups. In this case, the switching status or the brightness value feedback of a group is
not necessarily unique.
Example 1: Group 2 is set to 10% brightness. Group 3 is then dimmed to a brightness value of 20%.
The lamps of group 3 will accept the brightness value of 20% that was called up last. The feedback
of group 2 remains on 10%, although some of the devices that belong to the group have been set to
20% brightness.
Example 2: group 2 is switched on and assumes the brightness value of 100%. The status of group 3
remains at 0% brightness (OFF) internally in the DALI Gateway. The brightness of group 3 has now
been increased. The lamps of group 3 will adjust to the dimming (increasing brightness starting at
minimum brightness) even though these lamps had been switched on before via group 2.
Basically, the assignment of DALI devices to groups is arbitrary. For the reasons mentioned above it
is recommended not to assign the devices to several groups at the DALI. Preferably, the devices
should be allocated to separate instead of overlapping groups. A KNX/EIB link via the group
addressing in the ETS is also preferred.
In the plug-in each group can be separately parameterized. During the programming with the ETS,
the individual DALI devices will be programmed with the parameter data of the assigned groups. All
devices assigned to a DALI group will be put into operation in the exact same way.
If, however, DALI devices have been assigned to several groups these devices will receive the
project design with the highest group number.
By activating the “Delete assignment” button in the lower margin of the commissioning environment
all assignments between the DALI devices and the different groups can be deleted. However, not
only the assignments will be reset in the plug-in but the commissioning parameters of the DALI
Gateway will also be adjusted. The plug-in will establish a communication to the Gateway via the bus
connection of the ETS 3 and delete all assignment in the device memory. This may take some time.
The progress is shown during the deleting. In case of a faulty bus communication the plug-in will
abort the operation without deleting any assignments in the project design or in the device.
DALI devices previously identified are not deleted but will have no group assignments.
The “Default” button will reset all commissioning parameters. Assignments of DALI devices to groups
get lost from the project design and the DALI Gateway if the “Default” button in the commissioning
environment has been activated!
