FB_DALIV2QueryAssignedColour
The ASSIGNED COLOR variable is read from the DALI control gear. This contains the color (see table) assigned to the specified output channel (0 - 5). 255 (MASK) is returned if a non-existent channel number is specified.
Value | Description |
|---|---|
0 | No color assigned |
1 | Red |
2 | Green |
3 | Blue |
4 | White |
5 | Amber |
6 | Freely selectable color |
The function block changes the DTR (data transfer registers) for all DALI control gears of the DALI line.
The function block supports the following color representations:
- 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;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nChannel : BYTE;
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).
nChannel: Channel number (0 - 5).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
nAssignedColour : BYTE;
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)
nAssignedColor: Assigned color of the channel (see table).
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).
