OPC UA Insights

What is OPC UA?

OPC UA (Open Platform Communications Unified Architecture) is a platform-independent, service-oriented architecture that integrates all kinds of industrial data. It provides a standard way for different devices and systems from different vendors to communicate and exchange data securely and reliably. It's commonly used for industrial automation, machine-to-machine (M2M) communication, and connecting industrial equipment to enterprise systems.
