GrafcetMaker lets you draw GRAFCET charts (IEC 60848), check them and run them in a simulator, right in your browser. These pages take you from your first chart to the advanced features.

New to GrafcetMaker?

• Open an example from the start screen (Help › Start screen and examples) and press F5 to watch it run.
• Take the ten-step tour (Help › Take the tour) to learn where everything is.
• Getting started: draw, check and simulate a small tank-filling chart in about ten minutes. Start here.
• GRAFCET basics: steps, transitions, receptivities, actions and the five rules that make a grafcet evolve. Read this if GRAFCET itself is new to you.

Guides

• Writing receptivities: AND, OR, NOT, rising ↑ and falling ↓ edges, timers, comparisons and step variables.
• Actions: continuous, conditional, stored on activation, deactivation or an event, and forcing orders.
• Editing diagrams: the keyboard and mouse moves that make drawing fast, branches, loops and automatic layout.
• Variables: inputs, outputs and internal variables, and exchanging them with Excel.
• Simulation: run a grafcet, change inputs, follow timers, read the chronogram and replay scenarios.
• Macro-steps, enclosing steps and forcing: structure large applications.
• Files, saving and export: autosave, files, PDF, images and spreadsheets.

Reference

• Glossary: the standard GRAFCET terms used in the app.
• Troubleshooting: what each problem message means and how to fix it.
