FB_DALIV2xInitialise

This command starts the addressing procedure for the control devices. Addressing must be terminated again using the function block FB_DALIV2xTerminate. The maximum duration is limited to 15 minutes. Each control device automatically terminates addressing after 15 minutes. The response of the control devices receiving this command depends on the parameter nParameter:
eDataFrameType = eDataFrameTypeOsram:
Value (binary) | Description |
---|---|
0000 0000 | All control devices respond. |
0AAA AAA1 | Control devices with the address AAA AAA respond. |
1111 1111 | Control devices without a short address respond. |
eDataFrameType = eDataFrameType24Bit:
Value (binary) | Description |
---|---|
0111 1111 | Control devices without a short address respond. |
00AA AAAA | Control devices with the address AAA AAA respond. |
1111 1111 | All control devices respond. |
Inputs
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
nParameter : BYTE;
eDataFrameType : E_DALIV2DataFrameType := eDALIV2DataFrameType24Bit;
END_VAR
Name | Type | Description |
---|---|---|
bStart | BOOL | 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 | BYTE | Specifies which control gears should respond to this command (see table above). |
eDataFrameType | Output format of the DALI command (eDALIV2DataFrameType24Bit or eDALIV2DataFrameTypeOsram) |
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_KL6821Communication (KL6821). |
Outputs
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
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). |
