Planning and Application
Example
An 8 bit scene (no. 8) comprises of some lamps, which are connected to two switch actuators and a
light controller DALI output. Furthermore, two blinds are integrated into the function Scene via a blind
actuator. The Scene can be retrieved via a single KNX telegram. The prerequisite for this is that all
devices have programmed scene 8 accordingly in their devices. After a telegram has been received, the
slave switches on its Scene number 8. The blind actuator moves the blinds to the corresponding posi-
tion; the lighting assumes the predefined brightness values and switching states defined by the Scene.
Benefits
The 8 bit scene offers some advantages compared to conventional scene programming via several KNX
groups. On the one hand, only a single telegram, which is received by all participants in the scene and
implemented accordingly, is sent on the KNX to retrieve a scene. On the other hand, the target positions
of the blind, the contact position of the switch actuator outputs and the brightness value of the light
controller are each stored in the devices and do not need to be sent via the KNX each time they are to
be retrieved.
Note
The scene numbering 1...64 is accessed via the KNX with a telegram value 0...63, whereby the
DGN/S 1.16.1 can only be used in one of the first 14 scenes.
