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
    NetId   : T_AmsNetId := ''; 
    Execute : BOOL; 
    Timeout : TIME := DEFAULT_ADS_TIMEOUT;
END_VAR

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

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

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

VAR_IN_OUT

VAR_IN_OUT
    Axis : AXIS_REF; (* Axis reference *)
END_VAR

Axis: Axis structure (see TcMC2.lib).

VAR_OUTPUT

VAR_OUTPUT
    Busy         : BOOL;
    Error        : BOOL;
    AdsErrId     : UINT;
    SercosErrId  : UINT;
    DiagNumber   : UDINT;
    Attribute    : DWORD;
END_VAR

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

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

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

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

Attribute: Supplies the Sercos parameter attribute.

DiagNumber:Supplies the diagnostic number.
