Lightscenes 1 ... 16 Control Scenes [Non EIS; 8-bit coded]:
All 16 scenes can be controlled
via this 1-byte communication object using a coded telegram. The number of the addressed
scene is received via a telegram together with the recall or store information. The communica-
tion object is only visible if the scenes have been activated in the
Scenes
parameter window
and the parameter option “Control scenes via” has been set to “1-byte telegrams” or “1-bit
and 1-byte telegrams”.
Telegram format (1-byte):
MOSS SSSS
(MSB) (LSB)
M: 0 – Scene is retrieved
1 – Scene is stored (if permitted)
X: Not used
S: Number of the scene (1 ... 16 : 00000000 ... 00011111)
Other values will ignored by the scene. A recall or storage of the scenes is not possible.
See appendix A2 for the exact key table of the 8-bit scene telegram.
An example of an 8-bit scene is described in chapter 5.1 “Application and planning”.
