The Blog
Written for people who run the line.
Product updates, company news, engineering deep-dives, and what we learn from the controls engineers who run real lines.
Industrial AI doesn’t have an intelligence problem. It has a context problem.
Today’s AI models are extraordinarily capable. But intelligence alone can’t tell you why a production line stopped, what an interlock protects, or what happens three stations downstream if an engineer changes a rung.

Why TIA Portal needs a Desktop Companion App, and Studio 5000 doesn’t.
Allen-Bradley gives you a clean, standard L5X export. Siemens TIA Portal doesn’t. Here’s what PLCs.ai actually supports across S7 platforms, and how the Desktop Companion App closes the export gap.
AI for Studio 5000 and Allen-Bradley PLCs, from explain to document.
Upload any Studio 5000 project and understand it in plain English. Explain, troubleshoot, generate, and document, all grounded in your actual L5X project.
Six things every PLC engineer runs into, and how PLCs.ai finds them automatically.
Cycle-time bottlenecks, dead code, missing interlocks, broken handshakes, race conditions, and signal tracing. Plain-English explanations of concepts that usually take years on the floor to learn to spot.
PLCs.ai vs. pasting your PLC files into ChatGPT.
A general-purpose chatbot can read a snippet of ladder logic. It can't reason across your whole project, simulate a change before it goes live, or guarantee your PLC code never trains someone else's model.
PLCs.ai is heading to Automate 2026, and skipping the booth.
We do not have a booth and we are not chasing badge scans. We want to talk to the engineers and plant managers living downtime every day.
We are changing the way engineers run production line automation.
If modifying a PLC project takes days, the real problem is not the code. It is that no one fully understands it. Here is what we are building to change that.
PLCs.ai welcomes Brian Tessier as an advisor to stay grounded in real manufacturing.
Brian Tessier, former VP Innovation at Schneider Electric, joins PLCs.ai as an advisor, bringing deep experience from the production floor to the executive suite.
PLCs.ai raises a $4M seed round to make PLC code universally accessible.
The round was led by Avila VC, with participation from Ocean Azul Partners, Sugar Free Capital, and ICI Fund.
