Fig. 16: Functional feedback diagram
Disable function as an additional function: A ‘blinking” DALI group will always be reported back as
“Switched on” and with the switch-on brightness. Switching status feedback will be transmitted for
disabled groups as well, if the outputs, for example, have been manually adjusted.
The characteristic dimming curve is logarithmic – as it is common in a DALI system. Thus, the
brightness behaviour of the DALI lights during the dimming will adjust to the sense of brightness of
the human eye. The DALI Gateway automatically converts the linear dimming progress in the
KNX/EIB into a logarithmic one (0 / 0 % ... 255 / 100 %). A value feedback to the KNX/EIB will also
be converted. This means that the internal calculation process may result in slight differences
between the brightness value that is specified and the brightness value that is returned (e.g.
specification = 50% -> returned = 49 %)!
