Releases · PLC-lang/rusty

This is a preview of the current state of RuSTy.

While the project is still in very active development, we believe that it could be used for most scenarios.

Features

Support for most common features of the IEC61131-3 ST definition
- Standard (non object oriented languages) language features
- Standard functions and Datatypes
- Variable Length Arrays
- Classes/Methods (Object Oriented) - Still a proof of concept
Support for Debugging ST code
Support for multiple target compilation
Support for build scripts/ project management

What's coming

Upcoming features include CFC/FBD support, full object oriented support, and parallel compilation.
