VAR_INPUT

VAR_INPUT
    stDriveRef : ST_DriveRef; 
    bExecute   : BOOL; 
    tTimeout   : TIME := DEFAULT_ADS_TIMEOUT;ND_VAR

stDriveRef: The drive reference can be linked in the System Manager between PLC and drive. The link can be done to an instance of the ST_PlcDriveRef. The structure ST_PlcDriveRef contains the NetID as byte array. The byte array can be converted to a string. See ST_DriveRef.

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

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

VAR_OUTPUT

    bBusy        : BOOL;
    bError       : BOOL;
    iAdsErrId    : UINT;
    iSercosErrId : UINT;

    sDiagMessage : ST_SoE_String;
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 attribut of the Sercos parameter.

sDiagMessage: Supplies the diagnose message.
