A PLC Swiss-Army Knife for Controls Engineers
Automate the repetitive, focus on the logic. PLCflow turns spreadsheets and L5X files into production-ready Rockwell code – in minutes, not days. I/O mapping, alarms, AI code analysis, and SCADA integration, all in one platform.
PLC programming hasn't changed in decades.
Your workflow should.
Every controls engineer has lived some version of this. You open your I/O Excel
spreadsheet, carefully craft your =CONCAT("XIC(","Device_", 123, "_Closed)",...) expressions for your project, drag it down a hundred rows,
and paste the results into Studio 5000®
. It's clever. It's faster than going manually.
But it's tedious, and fragile – it works until the address format
changes, a column gets reordered, or you hand it off to a junior designer, and the client
adds 15 more sensors a week out from commissioning.
PLCflow was built by controls engineers who got tired of the ironic repetition in an industry of automation. We automated the parts of PLC programming that should have been automated years ago - so you can spend your time on the logic that actually matters.
Built for commissioning.
A unified platform that bridges deterministic code generation and modern AI analysis tools.
Upload & Map
Import spreadsheets or use the built-in editor. Our engine automatically structures your I/O mapping and device definitions.
Generate & Analyze
Generate structured ladder logic, alarms, and parameters. Use AI to analyze existing code and add documentation.
Export & Deploy
Download L5X, CSV, and JSON files for use with Studio 5000 and Ignition®. No middleman required.
Advanced Code Intelligence.
Quickly detect logic bugs, unreachable rungs and copy-paste errors before you get to commissioning. Our analyzer scans your logic against industrial best practices in real-time.
- Instant logical validation
- Logic-error & naming checks
- Health scoring & recommendations
Automated I/O Generation.
Map your electrical drawings to structured text or ladder logic in seconds with our automated I/O engine. Turn weeks of tedious manual entry into seconds of automated generation.
Learn about I/O Code GenerationNatural Language to Ladder Logic.
Describe complex sequencer logic in plain English and watch the AI architect the robust underlying logic. From natural language to fully configured I/O definitions - conversational PLC programming.
"Create 10 motor devices for Zone A with standard DI/DO mapping and VFD speed references."
What changes when code writes itself
Hours to Minutes
Define your devices in a spreadsheet. Upload. Generate. What used to take a full day of manual rung entry now takes under a minute - with fewer typos and zero missed addresses.
Consistent Standards, Every Time
Every project follows the same naming conventions, UDT structures, and logic patterns. No more "that's how the last guy did it" - PLCflow enforces your standards automatically.
Catch Bugs Before Commissioning
The AI-powered Code Analyzer reviews your L5X files for logic errors, copy-paste mistakes, naming issues, and structural problems. Find the bugs in the office, not on the plant floor.
Scale Without the Pain
Duplicating logic across production lines, zones, or equipment sets? Bulk operations, smart duplication, and Precision Replace's 12-action pipeline handle the repetitive work - even across 50+ routines.
Seamless deployment. Zero friction.
Built for Allen-Bradley
Works with Studio 5000 for ControlLogix® and CompactLogix® systems. Import and export L5X files directly.
Ignition SCADA Integration
Bidirectional UDT conversion between Rockwell L5X and Ignition JSON formats. Bridge the PLC-to-SCADA gap without a spreadsheet.
One platform. Every tool you need.
From your first I/O list to your final commissioning check, PLCflow covers the full lifecycle of PLC code development for Allen-Bradley ControlLogix and CompactLogix systems.
PLC Code Generation
Automatically generate production-ready ladder logic, tag definitions, and AOI instances from spreadsheet-based I/O lists, alarm definitions, and parameter tables. Supports ControlLogix and CompactLogix platforms.
