A.4 Table of fading times Fade time (No. 8)
Using the communication object Fade time (DALI format) or (KNX format), it is possible that the DALI
fading time as defined in the DALI standard EN 62386-102 can be transferred via the DALI control line on
the KNX, so that the intended DALI devices use the DALI fading times. In DALI format, the dimming time
can be sent directly on the KNX as one of the 16 possible DALI values. Here the value of the
communication object corresponds with one of the time values (Fade times) in the DALI standard. The
individual values can be found in the following table.
Alternatively, a time value in multiples of 100 ms (DPT 7.0004) can be sent as a KNX value. In this case,
the received value is converted to the next possible DALI value. It is rounded off mathematically. The
values available in DALI can be found on the following table. Times exceeding 7725.1 ms are converted to
90.5 s (maximum DALI value).
The option time for dimming changeable via bus for the lighting groups can be selected in different
parameter windows and parameters, e.g. in
Dimming speed, time for 0...100 %.
The telegram values 0 to 15 correspond to the following DALI fading times and correspond to the
parameter settings of the DALI format:
