ABB i-bus KNX
Planning and application
Example
An 8 bit scene (no. 8) consists of some lamps, controlled using two switch actuators and lighting groups
of the DALI Light Controller.
Furthermore, two blinds are integrated into the Scene function via a blind actuator. The Scene can be
recalled 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 devices switch on their Scene with no. 8. The blind actuator
moves the blinds to the corresponding position, the lighting assumes the predefined brightness values
and switching states defined by the scene.
Advantage
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 a single telegram is sent on the KNX and
which is received by all participants in the scene and implemented accordingly. 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/S lighting groups are stored in the respective devices and must not be transferred on
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/S
can only be used in one of the first 14 scenes.
