Chart 35: Communication objects one‐surface dimming
The one‐surface dimming is performed by using only one channel. The communication object
"Shutter" is addressed by a long keystroke and performs the up‐ and down‐movement of the shutter.
The direction of movement depends to the last direction of movement. If the shutter were driven up
at the last time, they will be driven down at the next time. So the direction of movement changes
after every movement.
The communication object "Blinds/Stop" is addressed by a short keystroke. Addressing this object
stops a running movement of the shutter. Furthermore it will adjust the blinds if a shutter function is
selected for this channel. The direction of the adjustment changes also here after every movement in
the same way like the up/down moving of the shutter.
