FB_DALIV2AssignColourToLinkedChannel
Linked output channels are assigned to the defined color (see table). The linked channels are specified by bit 0 to bit 5 of the TEMPORARY RGBWAF CONTROL variable. The channel assignment is not changed if TEMPORARY RGBWAF CONTROL contains the value 255 (MASK). All TEMPORARY COLOUR SETTINGS are set to MASK after the use of this command.
Value | Description |
|---|---|
0 | No color assigned |
1 | Red |
2 | Green |
3 | Blue |
4 | White |
5 | Amber |
6 | Freely selectable color |
The DTR (Data Transfer Register) of all DALI control gears in the DALI line is changed by the function block.
The function block supports the following 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(). From version 2.6.0 of the libraries TcDALIV2 and TcDALIV2AppExtCmds, however, the Enable Device Type 8 command is internally placed automatically before all application extended commands for lamps for color/color temperature control with DALI interface. |
VAR_INPUT
bStart : BOOL;
nAddr : BYTE;
eAddrType : E_DALIV2AddrType := eDALIV2AddrTypeShort;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nColour : BYTE;
bStart: The block is activated by a rising edge at this input.
nAddr: The address of a participating device or of a group.
eAddrType: Short address, group address or broadcast.
eCommandPriority: The priority (high, middle, low) this command has when executed by the library.
nColour: Colour that is assigned to the output channels (see table).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
bBusy: When the 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 if 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 an instruction at the inputs.
nErrorId: Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of an instruction at the inputs. See Error codes.
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
stCommandBuffer: A reference to the structure for communication with the FB_DALIV2Communication() (KL6811) or FB_KL6821Communication() (KL6821) block.
