Migrate legacy PLC code in days, not months.
Don't rewrite. Translate.
Your PLC code works. The hardware doesn't. Spare parts are gone, the vendor moved on, and manual rewriting takes months while introducing costly errors.
Chronax Retrofit-as-a-Service uses deterministic compilation and AI-powered translation to modernize legacy code automatically — in days, with full test coverage, ready for any modern platform.
Deterministic translation
95%+ automated code translation through proven compiler technology.
AI for the last mile
AI helps translate the 5% beyond deterministic compilation, reviewed by engineers.
All major PLC brands
Support for major brands and proprietary languages — Siemens, Schneider and more.
Turnkey delivery
Delivered as a service — you receive working, tested code, ready to deploy.
From any source. To any target.
From any source to any target
Import from Siemens S7, TIA Portal, Schneider Control Expert, and proprietary formats. Export to Control Expert, TIA Portal, Rockwell Studio 5000, Codesys, or custom platforms. Missing your PLC brand? New import and export targets added on demand.
From PLC to edge device
Generate embedded code (C, Rust, Ada, SPARK) with the Chronax runtime for any platform — bare metal or OS-based. Replace expensive PLCs with industrial PCs or custom hardware.
Built to extend
Chronax's modular compiler architecture means new import frontends and export backends plug into a proven pipeline. Adding support for a new PLC brand takes weeks, not years — with the same reliability as every other target.
