The next level of industrial automation.

AI-powered agents draft PLC logic, simulate controls, and manage vendor migrations while you guide the outcome.

Get started

Write PLC logic faster than ever

Stop writing rungs by hand. Describe your control requirements in plain language and Plaxio's AI agent generates complete, wired IEC 61131-3 Ladder Diagram logic — motor start/stop sequences, interlock conditions, timer rungs, fault resets — and drops them directly into your project. What used to take hours takes seconds.

Plaxio feature: Write PLC logic faster than ever

Graphical and code — always in sync

Switch between the visual FBD graphical canvas and the underlying structured source in one click. Every node, wire, connection, and tag is editable in both views simultaneously — they never go out of sync. No import, no export, no re-entry.

Lossless export to every major vendor

Your logic. Every PLC. Export your project to Rockwell L5X, Siemens SimaticML, Schneider XEF, Codesys, or vendor-neutral PLCopen XML with zero data loss. Built-in pre-export validation catches tag mismatches, address conflicts, and compliance errors before they reach your hardware.

Live tag monitoring and editing

See every tag value in real time — output coils, set/reset latches, timers, counters, analog values — directly from the Tag Monitor panel while your program runs. Edit values on the fly, force bits, add tags mid-session, and verify your logic without leaving the editor or touching the PLC.

Built-in HMI simulation — no hardware needed

Design, wire, and test complete SCADA/HMI screens inside Plaxio. Connect your ladder logic to live HMI widgets — tanks, valves, pumps, gauges, indicators — and run your entire control system simulation locally. Catch commissioning issues before you ever touch a real PLC.

Vendor neutral — works with every PLC brand

Not locked to Rockwell. Not locked to Siemens. Plaxio is completely vendor neutral — build your project once and deploy to any PLC. Migrate legacy programs from one platform to another, standardize your team on a single tool, and eliminate vendor lock-in forever.

Version control with Git — built in

Your PLC programs are code. Treat them like it. Plaxio has Git built directly into the IDE — branch your logic, commit changes, diff rungs, merge updates, and roll back to any previous version in one click. Full team collaboration, zero file conflicts, complete audit trail.

Engineers who use it never go back.

"Deployments that used to take weeks of manual tag checking and commissioning are now done in minutes. Plaxio is an absolute game-changer for control engineers."

Diana Chen Director of Automation, Grid Solutions

"By combining traditional IEC editors with local LLMs, our engineering team has drastically accelerated logic drafting and safety verification."

Marcus Vance VP of Control Systems, Vanguard Automotive

"The offline HMI simulator integration is brilliant. You can edit Ladder Logic and immediately interact with the running simulation on your local laptop, with zero PLC hardware required."

Sarah Jenkins Principal SCADA Architect, Nexus Energy

Build smarter PLC programs. Starting today.

Join controls engineers who have already switched to the only IDE that combines AI, IEC 61131-3 compliance, and true vendor neutrality — all offline, all yours.
