4.2.4.8 Scene function
The room controller display compact module can be used in two different ways as part of a
scene control system...
-
Each rocker or button can work as a scene extension. This feature makes it possible to
recall or to store scenes which may be stored in other devices (see chapter 4.2.4.6.5.
Scene extension function).
-
The TSM can independently store up to eight scenes with eight actuator groups. These
internal scenes can be recalled or stored by the rockers or buttons (internal scene recall)
and also by the communication object "scene extension".
In the following subsections the internal scene function will be dealt with in greater detail.
Scene definition and scene recall
If the internal scenes are to be used, the parameter "Scene function" on parameter page
"Scenes" must be set to "Yes". The matching data types for the eight scene outputs must then
be selected and adapted to the actuator groups used. The types "Switching", "Value (0 … 255)"
or "Value / blind position (0 … 100 %)" can be selected. The data type "Scene extension"
makes it possible to implement dynamic processes by linking scenes temporally, e.g. for the
lighting control in a display window.
As a rule, Venetian blinds are controlled via two scene outputs. One output controls the blind
height and the other one adjusts the slat position.
The ETS offers the communication objects and the parameters of the scene commands
appropriate for these data types on the following parameter pages "Scene 1" to "Scene 8".
It is possible that the values for the individual scenes preset by the parameters are modified
later on with the storage function when the system is (see chapter 4.2.4.8. Scene function)in
operation. If the application program is then loaded again with the ETS, these locally adapted
values will normally be overwritten by the parameters. Due to the fact that it may take
considerable efforts to readjust the values for all scenes in the system, the parameter
"Overwrite scene values during ETS download ?" offers the possibility of retaining the scene
values stored in operation without overwriting them.
The scene parameters can be set on the parameter page of each individual scene output
("Scene output 1 ... 8"). The setting options are the same for all 8 scenes.
These internal scenes can be recalled directly via the rockers or buttons (function "recall internal
scene") and also by another KNX device via the "Extension input" communication object. This
1-byte communication object supports the evaluation of up to 64 scene numbers. For this
reason it must be specified which of the external scene numbers (1 … 64) is to recall the
internal scene (1 … 8). If the same scene number is listed for several internal scenes, it is
always only the first of these scenes that will be activated (scene with the lowest scene
number).
In some situations there may be the requirement that a group of actuators is not controlled by
all, but only by certain scenes. A classroom, for instance, may require open blinds for the
"Welcome" and "Break" scenes, closed blinds in the "PC presentation" scene and no change in
the "Discussion" scene. In this example, the parameter "Permit transmission ?" can be set to
"No" for the "Discussion" scene. The scene output is then deactivated during the corresponding
scene.
