Variables

Every DALI control gear for color/color temperature control has a certain number of variables (parameters ) from which it is possible to read a variety of information or to modify individual parameters.

Some variables can be read directly by DALI commands (e.g. FB_DALI209QueryColourStatus). The function block FB_DALI209QueryColourValue can be used to read out further variables.

In the case of 1-byte values the value 255 is also called MASK.

In the case of 2-byte values the value 65,535 is also called MASK.

Necessary color representation

Specifies the color representation that the DALI control gear must support so that it contains the appropriate variables:

Value

Description

0

xy coordinates

1

Color temperature Tc

2

Primary (color) N

3

RGBWAF

xCoordinate / temporaryXCoordinate

Chromaticity coordinate x in the xy color type.

The x-Coordinate is specified in Mirek.

It can vary from 0 Mirek (0 K) to 65534 Mirek (15.26 K).

At a value of 65535 (MASK), the value is not defined.

yCoordinate / temporaryYCoordinate

Chromaticity coordinate y in the xy color type.

The y-Coordinate is specified in Mirek.

It can vary from 0 Mirek (0 K) to 65534 Mirek (15.26 K).

At a value of 65535 (MASK), the value is not defined.

colourTemperatureTc / temporaryColourTemperatureTc
