﻿The extended scene recall allows up to 16 scenes of a DALI system to be called up in sequence. Here, scene recall takes place via the 1-bit communication object "Extended scene recall". Each ON telegram received via this object recalls the next of the available scenes in the configuration. Each OFF telegram received recalls the previous scene.

In the event of an extended scene recall, the gateway always recalls the neighbouring scene - starting with the scene most recently recalled by the extended recall. It is irrelevant whether the scene is active (scene number = "1...64" or scene active) or inactive (scene number = "0" or scene inactive). When an ineffective scene is recalled by the extended scene recall, the assigned group or single device does not react.

Only the scenes available in the scene configuration can be selected via the extended scene recall (with "variable" defined by the parameter "number of scenes", with "fixed" always all 16 scenes). After a reset (bus/mains voltage return, ETS programming operation), an ON or OFF telegram always recalls scene 1 first.
