OPC UA
OPC UA (Open Platform Communications Unified Architecture) is an open, secure, platform-independent standard for industrial data exchange between machines, control systems and software. It is a key enabler of Industry 4.0 interoperability.
OPC UA provides a common language for devices and systems from different vendors to share data securely, with built-in authentication and a rich information model. It underpins much of the connectivity in modern smart factories, letting IIoT platforms, historians and analytics tools pull data without bespoke integrations for every device.
