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	E_DALIV2CommandPriority	Priority (high, medium or low) with which the command is processed by the library.
eDataFrameType	E_DALIV2DataFrameType	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.

Requirements

Development Environment	PLC library to include
