A client services one section of a manufacturing system and connects to tens if not hundreds of end devices, the servers. That’s somewhat confusing for IT people. Before I answer the question of when a device should be an OPC UA Client or a Server, let’s look at what OPC UA Clients and Servers do.

OPC-based communications for data exchange years ago became a stable standard in industrial hardware and software applications. OPC eliminates the requirement to write a custom interface, or server/driver, to exchange data with hardware field devices. This is achived by defining a common, high performance interface that permits this work to be done once, and then easily reused by HMI, SCADA, Control and custom applications.
