Parameters:

Returns:

Examples:

In addition to the parameters already explained, the following variables must be created / transferred for the implementation in TwinCAT 3:

Beckhoff parameter:

    bAstDeleteProgram
    A boolean variable that can be used to trigger the execution of the DeleteProgram command.
    outputAstDeleteProgram
    An instance of the ST_VoidOutputData structure into which the return value of the DeleteProgram method is written.
    hrAstDeleteProgram
    This can be used to monitor the execution of the command. Error codes have the type HRESULT.
    fbAst
    An instance of the FB_AST function block supplied with the DEPRAG Smart library.
    sDeviceId
    A string value specifying the device to be removed from the list of devices registered with the DEPRAG Smart OPC UA Server.
    ProgramNumber
    The DINT variable describes the number of the screwdriving sequence that is to be deleted.
    ConnectionHandle
    "ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client. 


VAR
       bAstDeleteProgram     : BOOL;
       outputAstDeleteProgram    : ST_VoidOutputData;                                          
       hrAstDeleteProgram     : HRESULT;

       fbAst   : FB_AST;
END_VAR

hrAstDeleteProgram := fbAst.DeleteProgram(
       bExecute    := bAstDeleteProgram,   
       ConnectionHandle := depragSmartConnection.ConnectionHandle,
       sDeviceId   := '0',
       ProgramNumber   := 2,
       OutputData   => outputAstDeleteProgram);
IF hrAstDeleteProgram <> S_FALSE THEN 
 bAstDeleteProgram := FALSE;
END_IF
