FB_DALIV2QueryAssignedColour

The variable ASSIGNED COLOUR 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 Register) for all DALI control gears of the DALI line.
The function block supports the color representations:
- RGBWAF
![]() | This command belongs to the application extended commands for lamps for the color/color temperature control with DALI interface. These only work if they are preceded by the Enable Device Type 8 command, which can be sent with the function block FB_DALIV2EnableDeviceType. The command Enable Device Type 8 is internally placed automatically before all application extended commands for lamps for the color/color temperature control with DALI interface. |
Inputs

bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nChannel : BYTE;
END_VAR
Name | Type | Description |
---|---|---|
bStart | BOOL | The function block is activated by a positive edge at this input. |
nAddr | BYTE | The address of a device or of a group |
eAddrType | Short address, group address or broadcast | |
eCommandPriority | Priority (high, medium or low) with which the command is processed by the library. | |
nChannel | BYTE | Channel number (0 - 5) |
Inputs/outputs
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
END_VAR
Name | Type | Description |
---|---|---|
stCommandBuffer | ST_DALIV2CommandBuffer | Reference to the internal structure for communication with FB_KL6811Communication (KL6811) or FB_KL6821Communication (KL6821). |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
nAssignedColour : BYTE;
END_VAR
Name | Type | Description |
---|---|---|
bBusy | BOOL | When the function block is activated the output is set, and it remains active until execution of the command has been completed. |
bError | BOOL | 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 | UDINT | 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). |
nAssignedColour | BYTE | Assigned color of the channel (see table) |
