FB_SoEReadClassXDiag

With the function block FB_SoEReadClassXDiag, the current Class 1 diagnosis (S-0-0011) ... Class 3 diagnosis (S-0-0013) can be read out as WORD. There is the conversion function F_ConvWordToSTAX5000C1D for the evaluation of the Class 1 diagnosis as a structure ST_AX5000_C1D, (see TwinCAT 3 PLC Lib Tc2_Drive documentation).

Inputs

VAR_INPUT
    sNetId     : T_AmsNetId := ''; 
    bExecute   : BOOL; 
    iDiagClass : USINT:= 1; (* 1: C1D (S-0-0011) is default, 2: C2D (S-0-0012), 3: C3D (S-0-0013) *)
    tTimeout   : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

Name	Type	Description
sNetId	T_AmsNetId	String, which contains the AMS Network ID of the PC (type: T_AmsNetId).
bExecute	BOOL	The function block is enabled via a positive edge at this input.
iDiagClass	USINT	Specifies which diagnosis should be read. The diagnostics parameters may vary from vendor to vendor. All diagnostics parameters (C1D ... C3D) or all bits are not always implemented in them. 1: Error: Class 1 Diag (S-0-0011) 2: Warnings: Class 2 Diag (S-0-0012) 3: Information: Class 3 Diag (S-0-0013)
tTimeout	TIME	Maximum time allowed for the execution of the function block.

Inputs/outputs

VAR_IN_OUT
    Axis : NCTOPLC_AXIS_REF;(* reference to NC axis *)
END_VAR

Name	Type	Description
Axis	NCTOPLC_AXIS_REF	Axis data structure of the type NCTOPLC_AXIS_REF

Outputs

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

Name	Type	Description
bBusy	BOOL	This output is set when the function block is activated, and remains set until a 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	In the case of a set bError output returns the Sercos error of the last executed command.
wClassXDiag	WORD	Returns the current Class X diagnosis.
dwAttribute	DWORD	Returns the attributes of the Sercos parameter.
