CODESYS Ladder Diagram
Planned import, project-aware AI assistance, and reviewed Ladder Diagram editing. Structured Text is outside the initial release scope. CODESYS import, editing, and export are not available in Chelix yet.
Intelligence for industrial automation
The AI coding workspace for PLC programming.
Understand complex control logic. Ask better questions. Make changes with an AI assistant built for the software that runs our machines.

CHELIX / THE WORKSPACERockwell L5X beta preview
Initial release / CODESYS first
Ladder Diagram.
AI-assisted edits.
We’re building Chelix’s initial release around CODESYS Ladder Diagram: understand an existing project, describe a change, review the proposal, and take it back to CODESYS for validation.
Rockwell L5X
The existing beta supports L5X exploration and controlled ladder edits. L5X Structured Text is currently read-only. Studio 5000 validation remains external.
Built to make changes
AI-assisted editing is central to the release: proposed changes, visible diffs, explicit approval, and export for engineering validation.
Physical AI / Built on industrial context
Intelligence belongs in
the physical world.
We see a future where intelligence is native to industrial systems. Chelix starts with better tools for the engineers who build and improve them: project context, AI assistance, and engineering judgment working together. Our initial customer focus is CODESYS Ladder Diagram editing.
The workflow / Shown in the L5X beta
From understanding
to the next revision.
01Understand
Get up to speed on unfamiliar logic.
Explore programs, routines, tags, and their connections in one workspace. Follow ladder logic with the context you need to understand how a machine is meant to work.
02Ask
A coding assistant that knows the project.
Ask questions in plain language. Chelix uses the selected program and routine to ground its answers in your control logic, with the relevant context kept in view.
03Edit
Turn intent into changes you can review.
Describe the change you want. Chelix proposes edits, checks them, and shows the diff. You review and approve the proposal before exporting back to your engineering workflow.
Chelix’s checks help you review a proposal. Exported L5X changes still need validation in Studio 5000.
Engineer in control
AI moves the work forward.
You make the engineering decisions.
Industrial software deserves an explicit review process. Chelix makes proposed changes and their findings visible, keeping the engineer involved from request to revision.
Grounded in the project
The L5X beta grounds answers in imported programs, routines, and tags. We’re bringing the same project-aware approach to CODESYS Ladder Diagram.
Changes you can inspect
See proposed edits, validation findings, and differences before you approve.
Your workflow stays yours
Review changes from project exports. The planned CODESYS workflow returns changes to CODESYS for validation; L5X beta exports require Studio 5000 validation.
