+ open62541 (http://open62541.org) is an open source and free implementation of
+ OPC UA (OPC Unified Architecture) written in the common subset of the C99 and
+ C++98 languages. The library is usable with all major compilers and provides
+ the necessary tools to implement dedicated OPC UA clients and servers, or to
+ integrate OPC UA-based communication into existing applications. open62541
+ library is platform independent.
