C implementation of OPC UA for industrial clients and servers.

open62541 is a C library for building OPC UA clients and servers or adding OPC UA communication to an existing application. Replaceable platform plugins support porting to embedded targets and other operating environments. Developers can use standard source or binary distributions, or include an amalgamated pair of C source and header files configured for their application.
