Expand your Industrial Research

Autonomy’s OpenPLC has been used in many [research papers] as a framework for industrial cyber security research.


Create your projects on OpenPLC Editor, a fully featured PLC Programming IDE. Execute them on the OpenPLC Runtime, a multi-platform, portable, PLC Runtime.



From an 8-bit AVR in an Arduino board to a 64-bit Xeon in a server rack, OpenPLC Runtime was designed with portability in mind. Its core was written in pure C, allowing it to be ported to many different hardware platforms.
