Planning and application
Example
An 8 bit scene (No. 8) comprises of some lamps, which are controlled via two switch actuators and
lighting groups of the DALI Light Controller.
Furthermore, two shutters are integrated into the function Scene via a shutter actuator. The Scene can
be retrieved via a single KNX telegram. The prerequisite for this is that all devices have programmed
scene No. 8 accordingly in their devices.
After a telegram has been received, the slave switches on its Scene No. 8. The shutter actuator moves
the shutters to the corresponding position; 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 when a scene is recalled only one telegram is sent via the KNX, which is
received and implemented by all members of the scene. On the other hand the target positions of the
blinds, the contact position of the switch actuator outputs and the brightness values of the DLR/A
lighting groups are stored in the respective devices and must not be transferred via the KNX each time
there is a recall.
Note
The scene numbering 1...64 is accessed via the KNX with a telegram value 0...63, whereby the DLR/A
can only be used in one of the first 14 scenes.
