ABB i-bus® KNX FUNCTION
4.1.12

Scenes

The function Scenes can be used to retrieve one of 16 scenes and incorporate additional KNX devices in a
scene. Each scene can be retrieved or saved using a single telegram. Additionally, scene assignments
1 ... 4 can be retrieved via the group object Retrieve scene assignment x .
Prerequisite: all devices are parameterized with the same scene number and retrieval takes place via the
same group address. For this purpose, a certain scene is assigned to the respective outputs in the pa-
rameter Scene number. The reaction (e.g. switching on output) on retrieval of this scene is defined in the
following ETS parameters.
The advantage of the function Scene is that all settings to be made for the devices of a scene are stored
in the device. Therefore, only the corresponding scene number must be sent when retrieving a scene via
the ABB i-bus® KNX. This considerably reduces the load on the ABB i‑bus® and prevents unnecessary tele-
gram traffic. Joint activation of devices/outputs with different input values (e.g. Switch Actuator and
Shutter Actuator) becomes possible as well.
4.1.12.1 Structure of scene telegram
A scene telegram contains the scene number (1 ... 64) and information about whether to retrieve or save
the scene.
Telegram value:
0 ... 63 = retrieve scene x (x = 1 ... 64)
128 ... 191 = save scene x (x = 1 ... 64)

Time functions

Three time functions are available for each output. One of the time functions can be selected in the pa-
rameter Enable function Time:
• → Function Staircase lighting, Page 92
• → Function Delay for switching ON and OFF, Page 94
• → Function Flashing, Page 95
The selected time function will be integrated into the other functions of the output.
More information → Function diagram of Switch Actuator, Page 77.
4.1.13.1 Function Staircase lighting
The function Staircase lighting can be used to implement time-controlled lighting (e.g. staircase light-
ing) or an application with a similar function (e.g. bathroom fan).
If the Reaction of output is defined as an NO contact , the contact is closed on receipt of a switch-on
value and then opened again after expiry of the Staircase lighting time.
If the Reaction of output is defined as an NC contact , the contact is opened on receipt of a switch-on
value and then closed again after expiry of the Staircase lighting time.
