FB_DALIV2StartIdentification

The function block FB_DALIV2StartIdentification is used to start a 10-second identification procedure of the control gear. The behavior is specified by the manufacturer. The lamp is usually switched on and off according to a certain pattern.

This command belongs to the application extended commands. These only work if they are preceded by the command Enable Device Type, which can be sent with the function block FB_DALIV2EnableDeviceType. The Device Type to be activated can be set at the nDeviceType input.

Inputs

VAR_INPUT
  bStart           : BOOL;
  nAddr            : BYTE;
  eAddrType        : E_DALIV2AddrType := eDALIV2AddrTypeShort;
  eCommandPriority : E_DALIV2CommandPriority := eDALIV2CommandPriorityMiddle;
  nDeviceType      : BYTE;
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.
nDeviceType	BYTE	Identifier for the device type (see table under FB_DALIV2EnableDeviceType)

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_KL6811Communication (KL6811) or 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).
