﻿The gateway can be used to control the light colour when using DALI operating devices of device type "DT8 - Colour Control". The gateway enables flexible colour control in the colour spaces "RGB", "RGBW", "HSV" or "HSVW". In the RGB colour spaces, the colours "red", "green", "blue" and optionally also "white" can be directly controlled by combined or separate communication objects according to the KNX specification. In the HSV colour spaces, separate objects are always available for controlling the light colour by absolute values for hue (H), saturation (S) and brightness value (V) and optionally also for the white value (W).
Whether the colour space is available with or without the white value "W" is set in the general configuration of the groups and single devices under "DALI system... -> Configuration groups" or "DALI system... -> Configuration Single Devices".

*RGB combined*: The colours "red", "green" and "blue" are individually controlled by absolute values by means of a common object. This object is 3 bytes in size (DPT 232.600). In addition to the default object, another object of the same data type is available for the status indication of the currently set colour. The gateway transmits the RGBW colours received from the KNX directly to the DALI side.

*RGB combined*: The colours "red", "green", "blue" and "white" are individually controlled by absolute values by means of a common object. This object is 6 bytes in size (DPT 251.600). The transmitted default colours are evaluated only if the corresponding 1-bit enable flags (bits 0...3) are in the data value "1". With "0", the respective colour is ignored. In addition to the default object, another object of the same data type is available for the status indication of the currently set colour. The gateway transmits the RGBW colours received from the KNX directly to the DALI side.

*RGB individually*: The colours "red", "green" and "blue" are individually controlled by separate objects. Switching (DPT 1.001 / ON & OFF), relative dimming (DPT 3.007 / dimming the colour intensity up and down incl. stop) and the specification of an absolute value (DPT 5.001 / 0...100%) are possible for each colour. If required, a status object is available for each colour, which indicates the set absolute colour value (DPT 5.001 / 0...100%). The gateway transmits the RGB colours received from the KNX directly to the DALI side.

*RGBW individually*: The colours "red", "green" and "blue" and "white" are individually controlled by separate objects in each case. Switching (DPT 1.001 / ON & OFF), relative dimming (DPT 3.007 / dimming the colour intensity up and down incl. stop) and the specification of an absolute value (DPT 5.001 / 0...100%) are possible for each colour. If required, a status object is available for each colour that indicates the set absolute colour value (DPT 5.001 / 0...100%). The gateway transmits the RGBW colours received from the KNX directly to the DALI side.

*HSV*: The colours "red", "green" and "blue" are individually controlled in the HSV colour space as an absolute value specification by separate 1-byte objects for the hue (H / DPT 5.003 / 0...360°), saturation (S / DPT 5.001 / 0...100%) and brightness value (V / DPT 5.001 / 0...100%). The gateway calculates the RGB values used in the DALI from the specified HSV values. In addition to the default objects, four other objects of the same data types are available for the status indication of the colour currently set.

*HSVW*: The colours "red", "green" and "blue" are individually controlled in the HSV colour space as an absolute value specification by separate 1-byte objects for the hue (H / DPT 5.003 / 0...360°), saturation (S / DPT 5.001 / 0...100%) and brightness value (V / DPT 5.001 / 0...100%). The white value is optionally specified by a separate 1-byte object (DPT 5.001 / 0...100%). The gateway calculates the RGB values used in the DALI from the specified HSV values. In addition to the default objects, four other objects of the same data types are available for the status indication of the colour currently set.
