FB_DALIV2xIdentifyDevice

The function block FB_DALIV2xIdentifyDevice starts the identification routine for the control device.

It takes approx. 10 seconds and ends automatically. The exact scope of the identification routine depends on the manufacturer of the control device.

Inputs

VAR_INPUT
  bStart            : BOOL;
  nAddr             : BYTE;
  eAddrType         : E_DALIV2AddrType := eDALIV2AddrTypeShort;
  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.
nAddr	BYTE	The address of a device or of a group
eAddrType	E_DALIV2AddrType	Short address, group address or broadcast
eCommandPriority	E_DALIV2CommandPriority	Priority (high, medium or low) with which the command is processed by the library.
eDataFrameType	E_DataFrameType	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).

Requirements

Development Environment	PLC library to include
