Built by engineers,
for engineers.
PLCflow started with a simple observation: controls engineers spend too much time typing code that a machine should be writing for them.
Reclaim the engineering,
not the typing.
Every PLC project has the same patterns - I/O mapping, alarm logic, parameter bounds. The logic is well-understood and highly repetitive. But the tools haven't caught up. Engineers still copy routines, find-and-replace tag names by hand, and manually type hundreds of rungs that follow the same template.
The lucky ones have an Excel sheet with a CONCAT() column quietly stitching tag names together - a workaround every controls
engineer has invented independently, and every one of them has eventually
outgrown.
We built PLCflow to change that.
PLCflow is a cloud-based platform that automates PLC code generation for Allen-Bradley ControlLogix and CompactLogix systems. It takes the work you already do in spreadsheets - I/O lists, alarm definitions, parameter tables - and turns it into production-ready ladder logic, tag definitions, and supporting files.

Workflow
Our Values
Ship real value.
Every feature exists to save time on actual projects. No bells and whistles - just tools that work.
Respect the craft.
PLC programming is safety-critical work. We build tools that make code more reliable, not just faster to write.
Stay close to the user.
The best product decisions come from engineers who use the platform on real projects. We build what the job actually needs.
More than code generation.
But code generation is only part of the story. PLCflow also brings AI-powered code analysis to PLC programming - reviewing your existing L5X files for bugs, anti-patterns, and improvement opportunities. The Comment Helper documents your ladder logic automatically. The Tag Database and UDT Library give your team a shared foundation that enforces standards across every project.
We're building the platform we wish we'd had on our last project. And we're just getting started.
To give every controls engineer access to tools that eliminate the tedious, error-prone parts of PLC programming - so they can focus on the work that requires real engineering judgment.
