Siemens just launched a purpose-built engineering AI that lives inside TIA Portal. The early numbers are hard to ignore.

If you have ever pasted PLC code into a generic AI tool and spent the next 30 minutes manually fixing everything it got wrong, this one is for you.

Siemens just launched Eigen Engineering Agent, and it is a different beast. Not a chatbot bolted onto the side of your workflow. Not a generic copilot that produces code you have to manually adapt. Eigen connects directly to TIA Portal and reads your actual project: your function blocks, your data types, your HMI screens, your drive configuration. The output it gives you is ready to use in your environment, not someone else's.

The name is not accidental. In mathematics, eigenvalues are the properties of a system that stay constant even as everything else transforms. That is what Siemens is going for here: a stable layer of industrial intelligence in a rapidly shifting AI landscape.

"This is an AI assistant truly built for industrial automation. It transformed a complex, multi-discipline challenge into a conversational workflow." Dr. Kevin Firouzian, CASMT

The results from the pilot, run with over 100 companies across 19 countries, back that up. Eigen delivers tasks 2 to 5 times faster than manual alternatives, with up to 80 percent higher solution quality and 50 percent greater engineering efficiency.

What does Eigen actually do? In short: anything you would normally spend hours grinding through in TIA Portal. SCL and LAD code generation, automated test and validation logic, WinCC Unified HMI scripting, VB to WinCC Unified migration, drive and axis configuration, PROFINET topology setup, bulk hardware import via spreadsheet, and project Q&A for legacy systems.

That last one is quietly significant. One automotive line builder in the pilot found that new engineers spent weeks just mapping their way around a project before they could contribute. With Eigen, they could ask questions directly: "Show me all blocks controlling Station 3." The answer came back immediately and accurately. Onboarding time dropped from weeks to days.

Eigen does not just generate and dump, either. It uses multi-step reasoning and self-correction, breaking complex tasks into steps, checking its own output against your project's standards, and iterating before handing anything back to you. That is the difference between AI that makes suggestions and AI that completes work.

"We are proud to shape this future together with Siemens. AI has the potential to unlock massive gains in productivity, cost efficiency, and competitiveness." Michael Luu, ANDRITZ Metals

Ready to try Eigen inside your own TIA project?

Eigen Engineering Agent is now available for TIA Portal users on V19, V20, and V21. Sign up for the free trial and see what it does when it actually knows your project, your standards, and your structure. No generic output. No manual rework.
