FB_DALIV2SetTemporaryRGBWAFControl

FB_DALIV2SetTemporaryRGBWAFControl 1:

Saves the value in the TEMPORARY RGBWAF CONTROL variable of the DALI control gear. The value can be read with the function block FB_DALIV2QueryColourValue(). The nTemporaryRGBWAFControl input thereby contains the new assignment (see table).

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

01 = color control

10 = standardized color control

11 = reserved

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;
nTemporaryRGBWAFControl : 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).

nTemporaryRGBWAFControl: Contains the assignment (see table above).

VAR_OUTPUT

bBusy    : BOOL;
bError   : BOOL;
nErrorId : UDINT;

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)

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).
