SIMATIC WinCC Open Architecture

The freedom of "Open Architecture"

SIMATIC WinCC Open Architecture is designed for applications of large scale and high complexity as well as 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 – even over 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 widely distributed systems.


WinCC Open Architecture V3.19 now available

The new product version 3.19 sports a higher-performing core than previous versions, with a core data throughput increase of up to 4 times. This boosted system reactivity opens up performance reserves and therefore the ability to grow existing projects without the need for additional hardware.

By replacing the RAIMA configuration database with SQLite, WinCC Open Architecture has been made year-2038 ready, including zero voltage safety, better performance as well as a smaller footprint.

Further enhancements have been made within the Dashboard, OPC UA, drivers, license management as well as closer integration into the existing Siemens Portfolio Landscape via the support of PM Add-ons.

Check out the new version today!
