This communication object is enabled if, in the
, page 53, the parameter Object format of flexible
time for dimming (Fade Time) is parameterized with the option DALI format in s [value 0...15 / 0...90.5 s].
Using this communication object, it is possible to define the fading time as described in the DALI standard EN 62386-102
via the DALI control by using the KNX, so that the intended DALI devices use the DALI fading times.
Telegram value:
0 to 15 corresponds to the fading times to DALI

The fade time is specified as the time duration required for changing the lamp power from the current brightness value to
the required target brightness. In the case of a switched off lamp, the preheat and ignition time is not included in the fading
time.
The set dimming time is retained at light controller supply voltage failure.
On KNX bus voltage failure the dimming time is lost and must be set once again. The value 5.7 s is set as a default value
until a new value is received.
