OPC Unified Architecture (OPC UA) has become a vital, vendor-independent communication protocol for industrial automation applications. Based on the client-server principle, it enables seamless communication from sensors and actuators up to enterprise systems or the cloud.
What is OPC UA?
OPC Unified Architecture (OPC UA) is a machine-to-machine communication protocol for industrial automation developed by the OPC Foundation. Distinguishing characteristics are that it is based on a client server communication and focuses on communicating with industrial equipment and systems for data collection and control. Read how OPC UA is opening up completely new possibilities and fields of application for industrial automation and control networks.
