Connects directly to your IDE. CODESYS and Beckhoff TwinCAT today, Siemens TIA Portal next.
Works with engineers building on
A small bridge runs on your machine alongside CODESYS, TwinCAT, or TIA Portal. PLC Assist sends instructions to the bridge — the bridge writes them into your open project, and streams existing code, compile results, and errors back to the agent. The loop closes automatically: the agent fixes what doesn't compile, on its own.
Fine-tuned on IEC 61131-3 — function blocks, scan-cycle idioms, and vendor-specific dialects. Reads your existing function blocks, GVLs, and data types, and accepts your own vendor manuals or coding standards on top, so the output matches your project's conventions rather than generic templates.
Upload a PDF specification and the agent turns it into function blocks, logic, and state machines — wired into your existing project.
After every change, the agent compiles your project, reads the compiler output, and resolves errors on its own. You review the final result.
Reviews your code for quality issues, missed edge cases, and risky patterns — like a senior engineer looking over your shoulder.
Generates documentation for your function blocks, libraries, and project structure — pulled from your own code and naming conventions.

A practical overview of AI tools that PLC programmers can use today -- from general-purpose chatbots like ChatGPT and Claude to specialized CODESYS copilots. What works, what doesn't, and how to choose.
Best practices for writing professional PLC code in Structured Text. Covers naming conventions, state machines, error handling, modularity, and testing strategies used by experienced automation engineers.
What if you could describe your PLC logic in plain English and get working Structured Text code back? AI chatbots for CODESYS are making this possible. Here's how it works and what to expect.
