8-bit scene
The DALI Gateway can be used wherever modern lighting technology is
required or requested.
This can be simple office lighting, complex lighting control in hotel foyers
or exhibition rooms as well as monitoring possibilities for the entire lighting
system.
You will find some tips and application examples in this section for practical
use of the DALI-Gateway DG/S 8.1
With the 8-bit scene, there is the possibility of recalling one of 16 light scenes
of the DALI Gateway or of combining with other KNX devices into an KNX
scene e.g. shutter actuators. This scene can be recall via a single telegram.
It is a prerequisite that all the operating devices which should be recalled are
parameterised with the same scene number.
Each KNX device involved in the scene receives the telegram and automa-
tically controls the outputs which belong to the scene. The lamps are swit-
ched on via the DALI Gateway with the parameterised transition period of
the scene.
Up to 64 different scenes can be managed via a single KNX group address,
whereby only the first 16 can be used for the DALI Gateway.
An 8-bit scene telegram (see appendix A2 for the key table) contains the
following information.
– Number of the scene (1...16)
– Store/recall scene
