OPCUA Insights

What is OPCUA?

OPC UA (Open Platform Communications Unified Architecture) is a platform-independent and service-oriented architecture that facilitates the secure and reliable exchange of data in industrial automation. It is commonly used for machine-to-machine communication, enabling interoperability between devices, machines, and systems from different vendors. OPC UA provides a standardized way to access real-time data, historical data, and events, as well as to model complex systems and expose their functionality.
