First, choose right HMI Connection Driver to connect to PLC, may be PLC-SIM (if you use PLC Simulator), or Ethernet card (If you use Profinet or Ethernet), or CP5611 (if use Profibus or MPI).. Second, compile your HMI runtime (rebuild all) and use WinCC RT Start to start HMI runtime. Now you can connect HMI runtime to your real PLC or sim PLC. Good luck
