FB_DALIV2QueryRGBWAFControl
The RGBWAF CONTROL variable is read from the DALI control gear.
Bit | Description |
|---|---|
0 | Output channel 0 / red |
1 | Output channel 1 / green |
2 | Output channel 2 / blue |
3 | Output channel 3 / white |
4 | Output channel 4 / amber |
5 | Output channel 5 / free selectable color |
6 - 7 | 00 = channel control |
If an output channel or a color is not supported, then the corresponding bit is FALSE.
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;
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).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
nRGBWAFControl : 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)
nRGBWAFControl: information about the channel assignment (see table above).
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).
