Features

  • Apache licensed (no cost)
  • Fully automated and published conformance tests
  • Non-blocking, event-driven architecture that scales to OS limits
  • Multi-core support for large frontends and device simulations
  • Simple, consistent programming model that lowers time to market

Quality

  • Proven solution with many production deployments
  • High unit test coverage
  • API that is both safe and easy to use

Documentation

  • Guide - Explains building and design (C++ and .NET)
  • C++ - Doxygen generated reference

What Users Say

We have recently started using opendnp3 to replace the previous library that we used in our DNP3 master driver. We are very impressed with the functionality, usability and performance of the library.
