Functional description
Fig. 16 Communication objects for "Channel X"
In the following section, the communication objects are described which
relate to a channel and all the DALI devices connected to it. It is a central
function (broadcast mode) which relates to all devices of the channel. This
function is comparable with the method of function of the ABB i-bus®
EIB / KNX 8-fold DALI-Gateway DG/S 8.1.
The first figure in the field "No." corresponds to channel A, the second figure
to channel B.

Channel X On/Off [EIS 1; 1-bit switching]: Using this object, the DALI device of the
channel is switched on or off according to the predefined brightness values (Devices
parameter window).
Telegram value "1": On
"0": Off
When an ON telegram is received, the parameter settings define if a predefined brightness
value or the value prior to switching off is set. The parameterised brightness value of the
switch ON value is set if the channel is switched on with any brightness value and it then
receives an ON telegram "1".
Switch ON values which are greater than or less than the max. or min. values will not be set,
but rather the parameterised max. or min. value. It can be set via parameters whether the
brightness value is dimmed or immediately applied.
1 Relative Dimming
&
19
Channel X Relative Dimming [EIS 2; 4-bit dimming]: The relative dimming telegram for the
corresponding channel is received via this object. After a start command is received, the
brightness is changed in the defined direction with the parameterised speed. If a stop
command is received before the end of the dimming process, the dimming process is
interrupted and the brightness value achieved is retained.
As this is a broadcast command, all devices of channel A and B will be dimmed together at
the same speed and synchronously.
Dimming values which are greater than or less than the max. or min. values will not be set,
the parameterised max. or min. values are retained when dimming is continued.
