A boolean variable that can be used to trigger the execution of the ReadPortNumber command.

TcpIpPortNumber
A DINT variable in which the port of the server is stored.

hrTcpIpReadPortNumber
This can be used to monitor the execution of the command. Error codes have the type HRESULT.

VAR
   bTcpIpReadPortNumber : BOOL;
   TcpIpPortNumber   : DINT;
   hrTcpIpReadPortNumber : HRESULT;

   fbTcpIp  : FB_TcpIp;
END_VAR

hrTcpIpReadPortNumber := fbTcpIp.ReadPortNumber(
        bExecute    := bTcpIpReadPortNumber,
        ConnectionHandle  := depragSmartConnection.ConnectionHandle,
        ClientId   := '0',
        Output    => TcpIpPortNumber);
IF hrTcpIpReadPortNumber <> S_FALSE THEN 
   bTcpIpReadPortNumber := FALSE;
END_IF
