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 unit is not excluded, then the output bAnswer is set to TRUE.
VAR_INPUT
bStart : BOOL;
eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
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 (see E_DALIV2CommandPriority).
eDataFrameType: Output format of the DALI command (eDALIV2DataFrameType24Bit or eDALIV2DataFrameTypeOsram) (see E_DALIV2DataFrameType).
VAR_OUTPUT
bBusy : BOOL;
bError : BOOL;
nErrorId : UDINT;
bAnswer : BOOL;
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)
bAnswer: The random address is smaller than or equal to the search address.
VAR_IN_OUT
stCommandBuffer : ST_DALIV2CommandBuffer;
stCommandBuffer: Reference to the internal structure for communication with the function block FB_KL6821Communication() (KL6821).
