FB_SoEReadDiagNumberList

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

Inputs

VAR_INPUT
    NetId       : T_AmsNetID := '';
    Execute     : BOOL;
    Timeout     : TIME := DEFAULT_ADS_TIMEOUT;
    pDiagNumber : POINTER TO ST_SoE_DiagNumList;
    Size        : UDINT;
END_VAR

Name	Type	Description
NetId	T_AmsNetID	String which contains the AMS Network ID of the PC (type: T_AmsNetId).
Execute	BOOL	The function block is enabled via a positive edge at this input.
Timeout	TIME	Maximum time allowed for the execution of the function block.
pDiagNumber	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.
Size	UDINT	Size of the list in bytes (as Sizeof())

Inputs/outputs

VAR_IN_OUT
   Axis : AXIS_REF;
END_VAR

Name	Type	Description
Axis	AXIS_REF	Axis data structure that unambiguously addresses an axis in the system. Among other parameters it contains the current axis status, including position, velocity or error state.

Outputs

VAR_OUTPUT
    busy        : BOOL;
    Error       : BOOL;
    AdsErrId    : UINT;
    SercosErrId : UINT;
    Attribute   : DWORD;
END_VAR

Name	Type	Description
Busy	BOOL	This output is set when the function block is activated, and remains set until a feedback is received.
Error	BOOL	This output is set after the Busy output has been reset when an error occurs in the transmission of the command.
AdsErrId	UINT	In the case of a set Error output returns the ADS error code of the last executed command.
SercosErrId	UINT	In the case of a set Error output returns the Sercos error of the last executed command.
Attributes	DWORD	Returns the attributes of the Sercos parameter.
