With a 1-bit object (Volume + = 1/Volume – = 0), you can change the volume one step up or down (relative control):
-
1 = one step up
-
0 = one step down
Absolute control means that you adjust the volume level on a scale by dragging the bar on the screen. You can choose whether the volume is transmitted as a percentage (DPT 5.001) or as a percentage (DPT 5.004) from 0 – 100 %.
