Retrieving scenes
Retrieving scenes by push-button does not access the
internal scene module, but rather only accesses the
bus externally via communication objects. If you there-
fore wish to retrieve scenes stored in the internal scene
module using a push-button, you must connect the cor-
responding communication object with the extension
unit object of the scene function.
There are two types of scene function:
• Normal
• Extended
Status indication
The status LED can:
• Be switched on or off continuously.
• Light up when pressed (for a long period), and go out
when released.
• Flash.
• Display the status of the status feedback object.
• Display the status of object A/B.
Normal scene function
With the normal scene function, a scene is retrieved by
a brief push-button action and a long push-button ac-
tion is used to save a scene. You merely have to set the
time after which a push-button action is identified as be-
ing long, together with the triggering of the status LED
and the scene address.
Extended scene function
With the extended scene function, you can set different
actions for short and long presses of a push-button,
both for when the push-button is pressed and for when
it is released. You can also set a cycle time which can
be parameterised for each object.
The following activation sequence chart shows the
phases into which the scene function is divided:
