FB_SoEReadDiagNumber

FB_SoEReadDiagNumber 1:

The functionblock FB_SoEReadDiagNumber can be used to read the actual diagnose number as UDINT (S-0-0390).  

VAR_INPUT

VAR_INPUT
    sNetId   : T_AmsNetId := ''; 
    bExecute : BOOL; 
    tTimeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

sNetId: A string containing the AMS network identifier of the PC.

bExecute: The block is activated by a rising edge at this input.

tTimeout: Maximum time allowed for the execution of the function block.

VAR_IN_OUT

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

Axis: Axis structure.

VAR_OUTPUT

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

bBusy: This output is set when the function block is activated, and remains set until an acknowledgement is received.

bError: This output is set up after the bBusy output has been reset if there has been an error in transmission of the command.

iAdsErrId: Supplies the ADS error code associated with the most recently executed command if the bError output is set.

iSercosErrId: Supplies the Sercos error code associated with the most recently executed command if the bError output is set.

dwAttribute: Supplies the Sercos parameter attribute.

iDiagNumber:Supplies the diagnostic number.
