This communication object is enabled if, in the
time for dimming (Fade Time) is parameterized with the option KNX format in 100 ms [value 0...65,535/0...9050 ms].
Using this communication object, it is possible to define the fade 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 fade times.
Please note that it is not the sent KNX value that is used in the DALI, but rather the nearest DALI value. The DLR/S
performs a mathematical rounding off in order to determine the most suitable DALI value.
Telegram value:
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.
