OpenOPC for Python

OpenOPC Gateway Service

The Gateway Service is an optional Windows service which handles all the Win32 COM/DCOM calls used by the OpenOPC library module. This offers the following potential advantages:

  • Avoidance of DCOM security headaches and firewall issues when running the OPC client and OPC server on different nodes.
  • The ability to write OPC client applications that can run on non-Windows platforms such as Linux, Unix, and Mac OS X.

    Installing the service

    C:\OpenOPC\bin> OpenOPCService.exe -install
    Installing service OpenOpcService
    Service installed

    Starting the service

    C:\OpenOPC\bin> net start zzzOpenOpcService

    Stopping the service

    C:\OpenOPC\bin> net stop zzzOpenOpcService
