C++ Adapter Toolkit
From MTConnect® User's Portal
The C++ Adapter toolkit is the most widely used framework currently in production. It is a simple socket server library that can be extended to support most machine tool interfaces. It was originally written to provide a simple framework to develop from, but has grown through example. In the near future we need to take the time and restructure the code to break out the library elements (the src directory) and build it separately from the projects.
