Example 6: A scene actuator
A scene actuator is to be realized for the installation in Figure 22. The switch is configured in the ets
to work as a scene switch: Calling the scene is initiated by simple pressing and saving of a preset
scene by a long key press. The ETS program is such that the switch calls a scene with number 1 at
address 1/0/0.

Therefore, our task is:
Within the KNX network, the Enertex
®
EibPC should behave like a scene actuator, which has
been parametrized at address 1/0/0.
To define a scene actuator, use the function
scene(
GroupAddressSceneBlock
,
GroupAddressActuator1, GroupAddressActuator2,
, ... GroupAddressActuatorN)
You can “connect“ up to 65,000 actuators to this one scene actuator. The number of arguments, i.e.
the actuators assigned to a scene actuator and a scene function, respectively, is arbitrary.
The scene actuator can store 64 different scenarios (Values 0 to 63). By the
GroupAddress
SceneBlock
(8-bit unsigned)
, these scenario numbers (0u08 until 63u08) are stored and retrieved by
their appropriate actuators. As usual, the actuators and switches have to be programmed in the ets.
By the scene function, this task is easily solved as follows:
[EibPC]
scene('1/0/0'u08, "Lamp-1/1/1“, "'Dimmer-1/2/2")
More is has not to be done. Now, in the Enertex
®
EibPC one scene actuator is created with 64
accessible scenes. Of course, you can address scenes with manual group addresses.
Stored scenes will be preserved even at a temporary separation of the Enertex
®
EibPC from the
power supply or at the modification of the application software (re- and changed import). If you want
to delete the scenes completely from the permanent memory of the Enertex
®
EibPC, select the
corresponding item in the menu EibPC. If you assign changed group addresses in the application
program to the scene actuators stored in the Enertex
®
EibPC, you should do so in any case.
