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 translates 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.
Import from any legacy PLC
Siemens S7, TIA Portal, Schneider Control Expert, and proprietary formats supported. Need another platform? Added in ~4 months.
Export to any modern target
Generate code for Control Expert, TIA Portal, Rockwell Studio 5000, or custom platforms. New backend support: ~3 months.
Extensible platform support
Proven compiler technology enables fast platform expansion. New import frontend: 4 months. New export backend: 3 months. Predictable, reliable.
Your platform, on demand
Missing your specific PLC brand? We add support for any source or target platform — guaranteed timelines, compiler-grade quality.
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.
