KNX function "Scene extension"
For each button with the function set to "scene extension unit" the ETS indicates a 1-byte
communication object and the "Function" parameter which distinguishes between the following
settings...
-
"Scene extension without storage function",
-
"Scene extension with storage function",
In the scene extension function, the device transmits a scene number (1…64) to the bus, which
is preset in the ETS via a separate communication object after a button-press according to KNX
data type 18.001. This feature permits recalling scenes stored in other devices and also storing
them, if the storage function is used.
In the setting "Scene extension without storage function", a button-press triggers the simple
recall of a scene. The device then transmits the configured scene number immediately on
pressing the button. A long button-press has no additional effect.
In the setting "scene extension with storage function", the device monitors the length of the
actuation. A button-press of less than a second results in a simple recall of the scene as
mentioned above. After a button-press of more than five seconds, the device generates a
storage instruction and transmits a storage telegram to the bus according to KNX data type
18.001.
An operation lasting between one and five seconds will be discarded as invalid. The device then
does not react to the button-press.
The parameter "Scene number on pressing the button" specifies which of the maximum of 64
external scenes is to be activated after a button-press.
i
The "Scene extension" function is only available for buttons.
The KNX function "Scene extension with storage function" can particularly affect the status LED
allocated to the actuated button. If the status LED is configured to "button-press display", the
LED always lights up for the configured light period when the button is pressed (1...5 s). When
transmitting a storage telegram after pressing the button for a long time (> 5 s), the status-LED
is additionally activated for 3 seconds in order to indicate that the storage instruction was
transmitted to the bus.
