FB_DALIV2xInitialise
This command starts the addressing procedure for the control units. The addressing has to be halted again with the FB_DALIV2xTerminate() function block. The maximum duration is limited to 15 minutes. Each control unit stops the addressing independently after 15 minutes. The response of the control units receiving this command depends on the parameter nParameter:
eDataFrameType = eDataFrameTypeOsram:
Value (binary) | Description |
|---|---|
0000 0000 | All control units respond. |
0AAA AAA1 | Control units with the address AAA AAA respond. |
1111 1111 | Control units without a short address respond. |
eDataFrameType = eDataFrameType24Bit:
Value (binary) | Description |
|---|---|
0111 1111 | Control units without a short address respond. |
00AA AAAA | Control units with the address AAA AAA respond. |
1111 1111 | All control units respond. |
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nParameter : BYTE;
eDataFrameType : E_DALIV2DataFrameType := eDALIV2DataFrameType24Bit;
bStart: The function block is activated by a positive edge at this input.
eCommandPriority: Priority (high, medium or low) with which the command is processed by the library.
nParameter: Specifies which control units are to respond to this command (see table above).
eDataFrameType: Output format of the DALI command (eDALIV2DataFrameType24Bit or eDALIV2DataFrameTypeOsram).
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_KL6821Communication() (KL6821).
