SIMATIC WinCC Open Architecture Systems
The SCADA System Without Limits

The freedom of “Open Architecture”

SIMATIC WinCC Open Architecture is designed for applications of large scale and high complexity projects with special requirements on system prerequisites and customized functionality. With SIMATIC WinCC OA, you can build vendor and platform independent SCADA systems that are scalable and offer unlimited global access over the web, native iOS and Android user interfaces or browser-based clients. Due to the scalability and flexibility it is the perfect choice to create solutions including centralized control stations and geographically wide distributed systems.
