Disconnect

TwinCAT TIA
Network TCP/IP client ActiveClients One client

ns=2;s=DEPRAG Smart/Network/TCP/IP/ActiveClients/0/Disconnect

The command terminates the connection between TCP/IP client and server.

Returns:

    Disconnect
    A variable of the OpcMethodReturnValueVoid type. The method has no command-specific return values.

Examples:

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

Beckhoff parameter:

    bTcpIpDisconnect
    A boolean variable that can be used to trigger the execution of the disconnect command.
    OutputDataTcpIpDisconnect
    An instance of the ST_VoidOutputData structure into which the return value of the Disconnect method is written.
    hrTcpIpDisconnect
    This can be used to monitor the execution of the command. Error codes have the type HRESULT.
    fbTcpIp
    An instance of the "FB_TcpIp" function block supplied with the DEPRAG Smart library.
    sClientId
    A STRING(255) variable representing the ID of the client to be disconnected.
    ConnectionHandle
    "ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client. 


VAR
   bTcpIpDisconnect   : BOOL;
   OutputDataTcpIpDisconnect : ST_VoidOutputData;
   hrTcpIpDisconnect   : HRESULT;

   fbTcpIp  : FB_TcpIp;
END_VAR

hrTcpIpDisconnect := fbTcpIp.Disconnect(
        bExecute   := bTcpIpDisconnect, 
        ConnectionHandle := depragSmartConnection.ConnectionHandle, 
        sClientId   := '0', 
        OutputData   => OutputDataTcpIpDisconnect);
IF hrTcpIpDisconnect <> S_FALSE THEN 
    bTcpIpDisconnect := FALSE;
END_IF
