Most of us have dealt with legacy PLC code that had no documentation and was nearly impossible to understand. The Forge team is excited to announce the beta release of PLC Copilot. This new tool is built to help engineers, technicians, and anyone working with ladder logic understand their programs faster and with more confidence.
PLC Copilot is a desktop app that runs in conjunction with your favorite PLC programming software. It reads your ladder logic code, observes changes in your project, and provides clear explanations for how the logic works through a familiar chat interface. The AI highlights relevant rungs so you can trace behavior without digging through pages of code. The goal is simple: make PLC programming easier to understand and troubleshoot.
Why We Built PLC Copilot
Ladder logic is powerful, but reading and debugging it can take time. Complex interlocks, nested conditions, and vendor specific quirks often make things harder than they should be. We wanted an assistant that could translate ladder logic into explanations that make sense instantly.
PLC Copilot is an smart assistant that can answer questions like:
- What controls the VFD frequency output?
- Why rung 42 is not energizing?
- How does the alarms subroutine works?
- Which conditions can prevent this motor from starting?
Our goal is to reduce the repetitive mental load that comes with working through big PLC programs.
What You Can Do Today
The beta version of PLC Copilot connects to your PLC programming software and gives you instant access to three core capabilities through a simple chat interface:
Code Review — Ask any question about your ladder logic and get instant explanations of how the code works, including logic flow and conditions. The AI highlights relevant rungs so you can trace behavior without digging through pages of code.
Debug — Quickly identify and troubleshoot issues in your programs. Trace logic paths, understand why conditions aren’t being met, and get recommendations for fixing problems.
Documentation — Automatically generate comprehensive documentation for your PLC programs. Get clear explanations of logic flow, I/O mappings, and system behavior without the manual work.
Whether you’re working with legacy code, troubleshooting production issues, or training new team members, PLC Copilot accelerates your workflow by making complex ladder logic instantly understandable. The number of supported PLC programming software integrations is growing constantly, so you can use it with your existing tools.
Your Data and Ownership
Your projects remain private and secure. We use secure authentication, strong encryption, and industry-standard security practices to ensure your projects stay secure and safe. We never use your PLC code to train our AI models without your consent.
Anything generated by PLC Copilot is completely yours. You have full rights to use, modify, distribute, or sell the generated code or content however you choose.
Join the Beta
PLC Copilot is still growing and improving, and your feedback will help shape the future of the app. If you work with ladder logic, this is the perfect time to try the beta and tell us what would make your workflow smoother. The Beta version is offered for free for a limited time.
