Modern Software Engineering Meets PLC Programming

Modern Software Engineering Meets PLC Programming

Modern Software Engineering Meets PLC Programming

  • Unit & functional testing: Validate logic before commissioning—no hardware required

  • Git integration: Track every change, merge code cleanly, rollback instantly

  • CI/CD pipelines: Automated build, test, and deploy for industrial control systems

  • AI-powered tools: Code translation, refactoring, and test generation

Test and Simulate Before You Ship

Find bugs at your desk, not during commissioning. Save weeks of on-site debugging.


Find bugs at your desk, not during commissioning. Save weeks of on-site debugging.


  • Simulate and debug your complete PLC program on your laptop—faster than real-time

  • Create automated test scenarios that validate behavior under every condition

  • Arrive on-site with confidence: your code already works


Commissioning becomes deployment, not debugging.

Deploy Anywhere: PLCs, Edge, Cloud, Embedded


One codebase. Infinite deployment options.


One codebase. Infinite deployment options.


Run your control program on any target platform:


  • Traditional PLCs from any vendor (Schneider, Siemens, Rockwell, Beckhoff, Codesys)

  • Your Linux or Windows development machine for testing

  • Embedded systems (Raspberry Pi, industrial PCs, custom hardware)

  • Docker containers for edge computing and cloud deployment

AI-Ready Control Systems

Integrate AI/ML outputs directly into your real-time control logic.


Integrate AI/ML outputs directly into your real-time control logic.


Modern automation demands smart decision-making. Chronax makes it easy to incorporate AI-processed inputs and outputs in your control programs. Connect machine learning models, predictive maintenance algorithms, or image recognition systems—without compromising deterministic real-time behavior.
