GRAFCET: Master Control with Grafcet++ - Learn & Simulate

Master the art of GRAFCET for process control! This course provides a comprehensive understanding of GRAFCET, a powerful sequential control method, focusing on its application in sequence control tasks. You'll delve into the fundamental building blocks of GRAFCET and progress to more complex control sequences.

This is a SPA (Single Page Application) built using Google Chrome and JavaScript (with the JS++ framework), giving you complete access to the source code. The necessary server components, like Node.js, can be easily installed on your Windows 10 PC – allowing you to create, test, and simulate GRAFCET plans directly in your browser.

Key Features & Content:

• Core GRAFCET Concepts: Understand the essential components and principles of GRAFCET control.
• IEC 61131-3 Integration: Explore components from the widely used IEC 61131-3 standard (FUP - Functional Block Diagram), alongside familiar test elements.
• Enhanced Functionality (Grafcet++): Learn how to extend GRAFCET functionality with JavaScript, enabling advanced control logic. This is what makes it Grafcet++.
• Practical Application: Learn to apply GRAFCET to real-world scenarios with included exercises and solutions.
• Simulation & Testing: Test and simulate your GRAFCET plans with various operating components, including:
  • Motor
  • Pump
  • Valve
  • Cylinder
  • Reel-around table
  • Handling robot
• Control Elements: Master essential GRAFCET elements:
  • Steps & Transitions
  • Jump to Step
  • Continuous Actions
  • Storing Actions
  • Time-Dependent Assignments
  • Macro Steps
  • Alternative & Parallel Branching
  • Grafcet Chart for Testing
  • Mandatory Commands for Operation Selection & Emergency Stop
• IEC 61131-3 Implementation: Learn to implement your GRAFCET plans using IEC 61131-3 (Function Block Diagram) for basic applications.

Important Notes:

• The JavaScript source code for this SPA is provided for educational purposes only and is not covered by the course. Advanced use and modifications are your responsibility.
• This course does not cover inclusive steps, event-triggered actions, or mandatory commands within specific situations (e.g., Gx{50}).
• Negation is implemented using the '!' symbol, not a bar over the element.

This course is ideal for anyone looking to learn, understand, and test GRAFCET control systems. Develop your skills in process automation and sequence control with this hands-on, browser-based training.
