Application Interfacing Modbus RTU Devices to OPC UA

In the rapidly evolving landscape of Industrial IoT (IIoT) and Industry 4.0, the "language barrier" between the shop floor and the boardroom remains a primary challenge. On one side, we have Modbus RTU, the 1970s-era serial protocol that still powers millions of sensors, meters, and drives. On the other, we have OPC UA, the modern, secure, and platform-independent standard for high-level data exchange. Interfacing these two isn't just a technical task—it's the foundational application that turns raw electrical signals into actionable business intelligence.
