Built for the engineers who build the systems
Whether you're commissioning a greenfield plant or maintaining legacy systems, PLCflow fits into your workflow.
Greenfield Projects
The challenge
You've got hundreds of I/O points, dozens of device types, and a deadline that's already tight. Every motor, valve, and sensor needs structured logic, tag definitions, and alarm integration - and it all needs to follow the same standards. Right now that work lives in an Excel sheet held together by CONCAT() formulas and a prayer that nobody reorders the columns.
How PLCflow helps
Start with your I/O list in Excel. Upload it to PLCflow and generate all your device logic, alarm code, parameter setpoints, and tag definitions in one session. Use the Tag Database to build a reusable library for the next project. What used to take a team of engineers several weeks becomes a one-day task.
Multi-Line Expansion
The challenge
You're duplicating control logic across multiple production lines, zones, or equipment sets. The logic is identical - only the tag names and I/O addresses change. Copy-pasting across 10 lines means 10 chances to miss a replacement.
How PLCflow helps
Upload your master routine, define your variants, and let Duplication handle the rest. Bulk Insert adds common logic (safety interlocks, fault resets) across all routines in a single operation. Regex-powered find-and-replace ensures nothing gets missed.
Legacy Code Review
The challenge
You've inherited a program with 200 routines, no comments, and the original engineer left three years ago. Before you touch anything, you need to understand what it does and where the risks are.
How PLCflow helps
Upload the L5X file to the Code Analyzer for a full structural breakdown - health score, instruction report, rung-by-rung analysis. Then run Comment Helper to generate AI-powered documentation for every routine. Turn a black-box program into something your team can confidently maintain.
Change Management & Code Migration
The challenge
You need to track changes across PLC program versions - what was added, removed, or modified between revisions. Or you're migrating a program to new naming conventions, UDT structures, or equipment zones and need to make systematic changes without breaking anything.
How PLCflow helps
Use Logic Compare to diff two routine exports side-by-side with color-coded changes and AI-powered summaries. When you need to make systematic edits, Precision Replace gives you structure-aware find-and-replace with 12 action types, preview before apply, and reusable pipeline configurations.
SCADA Integration
The challenge
Your PLC tags use Rockwell UDT structures, but your SCADA system runs on Ignition. Converting UDT definitions between formats is a manual, error-prone slog.
How PLCflow helps
The UDT Converter handles bidirectional conversion between Allen-Bradley L5X and Ignition JSON formats. Configure OPC paths, map data types, and save your conversion settings for reuse across projects. Bridge the PLC-to-SCADA gap without a spreadsheet in between.
Standardization Across Teams
The challenge
Three engineers, three projects, three different naming conventions. Every program is structured differently, and onboarding new team members means explaining "how we do it here" every time.
How PLCflow helps
The Tag Database and UDT Library provide a shared foundation that every project builds from. Code generation enforces the same logic patterns, naming conventions, and UDT structures automatically. Standards stop being a document people ignore and start being the default.
