Overview KNX RGBW Converter

This function block converts between individual color channels (Red, Green, Blue, White) and a combined KNX RGB(W) data point. Depending on the selected type, either several individual channels are combined into a single value or a combined value is split into the individual channels. Supported are the 3-byte RGB data point (KNX DPT 232.600) and the 6-byte RGBW data point (KNX DPT 251.600). Which inputs and outputs the block has depends on the parameter „Type“.


Inputs

R / G / B / W
 Red / Green / Blue / White
 Individual color channels (0–255). Present for the types that combine individual channels into a single value.
WT
 RGBW 3 / RGBW 6
 Combined KNX data point (3-byte RGB or 6-byte RGBW). Present for the types that split a combined value into the individual channels.

Outputs
WT
 RGBW 3 / RGBW 6
 Combined KNX data point as the result of combining the individual channels.
R / G / B / W
 Red / Green / Blue / White
 Individual color channels as the result of splitting a combined value.

Parameters
Type
 Defines the conversion direction:
  • RGB->RGBW3: combines the channels Red, Green and Blue into a combined 3-byte RGB data point (DPT 232.600). 3 inputs (R, G, B) → 1 output (WT).
  • RGBW->RGBW6: combines the channels Red, Green, Blue and White into a combined 6-byte RGBW data point (DPT 251.600). 4 inputs (R, G, B, W) → 1 output (WT).
  • RGB3->RGB: splits a combined 3-byte RGB data point into the individual channels. 1 input (WT) → 3 outputs (R, G, B).
  • RGB6->RGBW: splits a combined 6-byte RGBW data point into the individual channels. 1 input (WT) → 4 outputs (R, G, B, W).
