Built for engineers like you
Inherited a 15-year-old program with 200 routines and zero comments. Previous engineer retired.
Upload L5X, generate AI comments for every rung, finally understand what the program does.
Handing off a project to the client's maintenance team, need to document every routine before delivery
Run Comment Helper, review and approve AI suggestions, deliver a fully commented L5X.
Inherited programs with 200 routines and no comments.

Before & After
See the difference PLCflow makes on a real project.
- Read each rung, figure out what it does, type a comment
- Repeat 500 times for a full program
- For inherited code, understanding often takes longer than rewriting
- New team members can't maintain what they don't understand
- Upload L5X, AI analyzes every rung automatically
- Review suggested comments with confidence scores
- Accept, edit, or reject individually
- Export a fully documented program ready for Studio 5000
Engineered for Complexity
Purpose-built capabilities for industrial-scale projects.
Rung-Level Analysis
AI reads each rung's instruction sequence and generates a plain-English comment explaining the logic's purpose and behavior.
Review Before Apply
Preview every generated comment before committing. Accept, edit, or reject on a per-rung basis with confidence scores.
