FB_DALIV2xCompare

The control gear compares its random address with the search address. If the random address is less than or equal to the search address and the control device is not excluded, then the output bAnswer is set to TRUE.
Inputs
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
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. | |
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;
bAnswer : BOOL;
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). |
bAnswer | BOOL | The random address is smaller than or equal to the search address. |
