FB_SoEReadDiagNumberList_ByDriveRef

With the FB_SoEReadDiagNumberList_ByDriveRef function block a history of the diagnostic numbers can be read as a list (S-0-0375).

Inputs

VAR_INPUT
    stDriveRef   : ST_DriveRef; 
    bExecute     : BOOL; 
    tTimeout     : TIME := DEFAULT_ADS_TIMEOUT;
    piDiagNumber : POINTER TO ST_SoE_DiagNumList;
    iSize        : UDINT;
END_VAR

Name	Type	Description
stDriveRef	ST_DriveRef	Reference to the drive. The reference to the drive can be linked directly to the PLC in the System Manager. To do this, an instance of the structure ST_PlcDriveRef must be allocated and the NetID must be converted from the byte array into a string (Type: ST_DriveRef).
bExecute	BOOL	The function block is activated by a positive edge at this input.
tTimeout	TIME	Maximum time allowed for the execution of the function block.
piDiagNumber	POINTER TO ST_SoE_DiagNumList	Pointer to the list of the last max. 30 error numbers. The list consists of the current and maximum number of bytes in the list as well as the 30 list items.
iSize	UDINT	Size of the list in bytes (as Sizeof())

Outputs

VAR_OUTPUT
    bBusy        : BOOL;
    bError       : BOOL;
    iAdsErrId    : UINT;
    iSercosErrId : UINT;
    dwAttribute  : DWORD;
END_VAR

Name	Type	Description
bBusy	BOOL	This output is set when the function block is activated, and remains set until feedback is received.
bError	BOOL	This output is set after the bBusy output has been reset when an error occurs in the transmission of the command.
iAdsErrId	UINT	Returns the ADS error code of the last executed command when the bError output is set.
iSercosErrId	UINT	Returns the Sercos error of the last executed command in the event of a set bError output.
dwAttribute	DWORD	Returns the attributes of the Sercos parameter.
