Id

Read TwinCAT TIA
Network TCP/IP client ActiveClients One client

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

Unique index with which the TCP/IP client can be retrieved from the "ActiveClients" list.

Examples:

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

Beckhoff parameter:

    bTcpIpReadId
    A boolean variable that can be used to trigger the execution of the ReadId command.
    TcpIpReadId
    A DINT variable in which the Id of the TCP client is stored.
    hrTcpIpReadId
    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.
    ClientId
    A STRING(255) variable representing the ID of the client.
    ConnectionHandle
    "ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client. 


VAR
   bTcpIpReadId : BOOL;
   TcpIpReadId  : DINT;
   hrTcpIpReadId : HRESULT;

   fbTcpIp  : FB_TcpIp;
END_VAR

hrTcpIpReadId := fbTcpIp.ReadId(
        bExecute    := bTcpIpReadId,
        ConnectionHandle  := depragSmartConnection.ConnectionHandle,
        ClientId   := '0',
        Output    => TcpIpReadId);
IF hrTcpIpReadId <> S_FALSE THEN 
   bTcpIpReadId := FALSE;
END_IF
