The Future of Web-Based SCADA: Edge Servers and Real-Time Visualization

Industrial automation is evolving rapidly, and web-based SCADA interfaces (HMI) are at the forefront of this transformation. Unlike traditional, platform-bound systems, modern solutions offer unprecedented flexibility and accessibility.

At Simon Moore Industrial Software, we develop HMIs that run on local edge servers within the factory environment. This architecture guarantees low latency and maximum availability, independent of the operator's operating system—whether it's Windows, Linux, or another platform.

Core Principles of Our Approach

• 1 Secure Real-Time Data: Sensor data and PLC statuses are streamed via encrypted WebSockets, creating a live dashboard that responds instantly to process changes.
• 2 Interface-Black, Data-Green: A dark interface (UI) minimizes eye strain for operators during long shifts, while critical data and alarms are highlighted in bright, readable colors like green.
• 3 Platform Independence: The application runs in a modern web browser. This eliminates the need for complex installations and simplifies maintenance and updates centrally from the edge server.

The visual presentation—the dashboard—is crucial. We design not only for functionality but also for intuitiveness. A clear hierarchy, logical grouping of controls, and consistent color coding (where green often represents 'normal operating condition') contribute to faster decision-making and reduced error margins.

"The power of a web-based HMI lies not in replicating an old application in a browser, but in leveraging modern web technologies to build more robust, scalable, and secure control interfaces for today's factory."

The future is focused on further integration with IIoT platforms, advanced data analytics directly at the edge, and even stronger cybersecurity measures built into the core of the application.
