FB_DALIV2QueryColourValue
The specified variable (color value) is read from the DALI control gear. The value to be read is defined by nParameter (see table below).
Certain variables can be read out directly via DALI commands (e.g. FB_QueryColorStatus() or FB_QueryRGBWAFControl ()). Further details on the variables can be found in section Variables.

Responses that concern an active color representation are valid only if the color representation of the requested color value is active (see FB_DALIV2QueryColorStatus()) or if the control gear is capable or reconverting the demanded color value from the active color representation to a color value of another color representation.
The reply must be 255 (MASK) if the control gear does not know the coordinates or if the primary color is not present.
The function block changes the DTR (data transfer registers) and DTR1 for all DALI control gears of the DALI line.
The function block supports the following color representations:
- xy coordinates
- Color temperature Tc
- Primary (color) N
- RGBWAF
 | This command belongs to the application-related expansion commands for lamps for the color/color temperature control with DALI interface. They function only if they are preceded by the Enable Device Type 8 command, which can be sent with the FB_DALIV2EnableDeviceType() function block. The Enable Device Type 8 command is internally placed automatically before all application-related expansion commands for lamps for the color/color temperature control with DALI interface. |
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;nParameter : BYTE;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
bStart: The function block is activated by a positive edge at this input.
nAddr: The address of a participating device or of a group.
eAddrType: Short address, group address or broadcast (see E_DALIV2AddrType).
eCommandPriority: Priority (high, medium or low) with which the command is processed by the library (see E_DALIV2CommandPriority).
nParameter: color value to be read out (see table above).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
nValue : UINT;
bBusy: When the function block is activated the output is set, and it remains active until execution of the command has been completed.
bError: This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in nErrorId. Is reset to FALSE by the execution of a command at the inputs.
nErrorId: Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs. (See error codes)
nValue: contains the value read out.
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;stCommandBuffer: Reference to the internal structure for communication with the function block FB_KL6811Communication() (KL6811) or FB_KL6821Communication() (KL6821).
