High-Speed I/O Code Generation
Generate structured ladder logic from I/O lists. Define devices (DI, DO, VALVE, AI, AO, MOTOR, VFD) in a spreadsheet or the built-in editor, and PLCflow creates device input/output logic, AOI definitions, alarm logic, and tag files.
How It Works
Import
Upload your I/O list CSV or enter devices manually
Configure
Configure device types, UDTs, and AOIs
Generate
Generate and download L5X files and tag CSVs
Built for engineers like you
Mapping 500+ I/O points for a greenfield bottling facility with motors, valves, VFDs, and analog sensors
Upload I/O list, configure device types, generate all logic and tags in one session.
Rapid prototyping a control system bid - need to show the client realistic code structure and tag counts
Enter 20 sample devices, generate L5X, demonstrate production-quality output in the proposal.
First project, 200 digital I/O points, no existing templates to copy from
Download PLCflow template, fill in device names, generate code that follows senior-level standards.
Manually typing hundreds of I/O tags and device rungs into Studio 5000.
What PLCflow Does
- Upload your I/O list CSV or enter devices manually
- Configure device types, UDTs, and AOIs
- Generate and download L5X files and tag CSVs
Before & After
See the difference PLCflow makes on a real project.
- Open Studio 5000, create tags one by one from a printed spreadsheet
- Type I/O addresses manually for every device
- Build device rungs for each motor, valve, and sensor
- Cross-reference everything, hope nothing was missed
- Upload your I/O list CSV or enter devices in the built-in editor
- Select device types, assign UDTs and AOIs
- Click Generate, download L5X and tag CSVs
- Import into Studio 5000, all logic structured and tagged
Engineered for Complexity
Purpose-built capabilities for industrial-scale projects.
Bulk Tag Generation
Generate hundreds of tags from a single I/O list with automatic naming conventions and address allocation.
AOI & UDT Mapping
Automatically wrap raw I/O signals into User Defined Types and Add-On Instructions based on device class.
Multi-Device Support
Handle DI, DO, VALVE, AI, AO, MOTOR, and VFD device types with pre-built logic patterns.
L5X & CSV Export
Native export for Studio 5000 L5X import and tag CSV files ready for direct project integration.
