Natural Language → Ladder Logic

Describe your control sequence in plain English and get professional, annotated IEC 61131-3 compliant ladder logic in seconds. No manual coding required.

Supports contacts, coils, timers, counters, and math blocks
Generates properly commented, readable rungs
Exports PLCOpen XML — compatible with all major PLC brands
Supports Siemens, Allen-Bradley, Mitsubishi & more

"Being able to describe what I need in plain language and get working PLC code has significantly reduced our implementation time."

Visual HMI Designer

Design modern, responsive operator interfaces with our drag-and-drop HTML5 canvas builder. The AI automatically links control elements to your PLC variables.

Intuitive drag-and-drop component library
Auto-binding to PLC I/O variables
Rich set of industrial widgets: gauges, tanks, motors
Mobile-responsive design output

"The HMI designer integration with PLC variables is a game-changer for rapid development and testing."

AI Debugging Assistant

Powered by Google Gemini, our debugging assistant analyses your ladder logic in real-time, identifies potential issues, and explains fixes in plain English.

Detects logic errors, short circuits, and race conditions
Explains problems in plain language — great for learning
Suggests optimised alternatives
One-click apply fixes to your program

"The AI debugging tool explains exactly what is wrong and how to fix it — something I've never seen in any other PLC tool."

Real-Time I/O Simulation

Test your ladder logic before deploying to real hardware. Watch inputs, outputs, timers, and counters update live on an animated ladder diagram.

Cycle-accurate PLC scan execution
Visual I/O state monitoring with colour feedback
Inject test inputs to validate all branches
Time-acceleration for testing timer-based logic

"The simulation environment has helped us catch issues early, saving thousands in potential downtime costs."

— Priya Mehta, Controls Engineer
