Awesome OPC UA Awesome

A curated list of Open Platform Communications Unified Architecture (OPC UA) libraries, tools and resources. Inspired by awesome-... stuff.

Including the information from traversaro/awesome-opcua

Open Platform Communications Unified Architecture (OPC UA) is the data exchange standard for safe, reliable, manufacturer- and platform-independent industrial communication.

For a brief introduction to OPC UA, check the What is OPC? UA in a Minute.

See the official OPC Foundation site for the official specifications and more information about the OPC UA standard.
