-open62541 (http://open62541.org) is an open source and free implementation of OPC UA (OPC Unified Architecture). open62541 is a C-based library that contains all the necessary tools to set up a dedicated OPC UA server or to integrate OPC UA-based communication into existing applications (linking with C++ projects [is possible](examples/server.cpp)). An example server implementation can be found in the /examples directory or further down on this page.
