Function Scene
With the scene using 8 bits, the push button issues the Switch Actuator with
the instruction to call a scene. The scene is not stored in the push button but
rather in the Switch Actuator. All Switch Actuators are addressed using the
same group address. It is thus sufficient to send a single telegram to recall
the scene.
A scene number is sent with the telegram value, which must correspond with
the scene number in the parameters of the Switch Actuator.
Up to 64 different scenes are managed via a single group address. The
scene telegram contains the call or store functions of a scene.
In the following, the scene function is described, which controls multiple KNX
devices.
With the scene it is possible to retrieve one of 64 scenes or to connect
multiple KNX devices in a scene. The scene can be retrieved or stored using
a single telegram. It is a prerequisite that all the operating devices are
parameterised with the same scene number.
Each KNX device involved receives the scene telegram and independently
controls the scenes values. Via the Switch Actuator, for example, the outputs
are switched on or off, the Blind Actuator moves the blinds to a defined
position, and the DALI Gateway dims its output to the pre-programmed
brightness values.
Up to 64 different scenes can be managed via a single KNX group address.
The following information is contained in a scene telegram:
Number of the scene (1…64)
Retrieve scene / store scene
