Creating WinCC- OPC drivers for serial and Ethernet devices


WinCC offers an extensive range of drivers and products like the TOP Server OPC Server add drivers for many common devices, but there are thousands of serial and Ethernet devices that do not have drivers to integrate into your SIMATIC HMI software. For these situations, you could write a custom driver and spend thousands of Euros or Dollars. The TOP Server UCON OPC Server provides a proven off-the-shelf solution at a fraction of the cost of custom drivers



  • Increased range of WinCC to device connectivity

  • Reduced engineering and integration costs

  • Increased value from using WinCC as your HMI/SCADA

Security information

To ensure the secure operation of a plant or machine it is also necessary to take suitable preventive action (e.g. cell protection concept) and to integrate the automation and drive components into a state-of-the-art holistic industrial security concept for the entire plant or machine. Any third-party products that may be in use must also be taken into account.
