Project design and programming
This function enables a brightness level to be specified via an 8-bit
brightness value. A detailed description of the communication objects can be
obtained in section 4.11.
Parameter: "Brightness values are called"
This parameter sets whether the dimmer jumps to the new dimming value as
quickly as possible on receipt of a brightness value (1 byte) or whether the
dimmer dims slowly to the brightness value.
Parameter: "Time for passing from 0% to 100%"
This parameter is visible if the dimmer dims to the new brightness value. The
speed at which the dimmer dims to a new brightness value can be defined
here. The time for dimming from 0...100% brightness is set here.
Parameter: "Upper dimming boundary for brightness values"
The upper brightness value for controlling the dimmer via a brightness value
telegram is defined here.
If a brightness value is received which is greater than the upper dimming
limit, the output sets the upper dimming limit. This value is also reported
back on the bus.
Parameter: "Lower dimming boundary for brightness values"
The brightness value for controlling the dimmer via a brightness value
telegram is defined here. If the dimmer receives a brightness value which is
smaller than the lower dimming limit (not zero), the lower dimming limit is
triggered.
Parameter: "Allow switching on via brightness values"
It can be set here whether the lighting can be switched on by a brightness
value telegram greater than "0" when it has been switched off.
Parameter: "Allow switching off via brightness values"
If a brightness value is received that is equal to zero, it can be set here
whether the lighting is switched off ("yes") or remains at the lower dimming
limit.
