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

1

Import

Upload your I/O list CSV or enter devices manually

2

Configure

Configure device types, UDTs, and AOIs

3

Generate

Generate and download L5X files and tag CSVs

Real-World Scenarios

Built for engineers like you

Controls Engineer

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.

System Integrator

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.

Junior Engineer

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.

The Problem

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.

Manual Process 4-8 hours
  • 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
With PLCflow Under 5 minutes
  • 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.

Code Generation

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.
