Finite State Machine (FSM) in PLC-Programming

Finite State Machine

What you'll learn
- Participants can understand and apply the fundamental principles of Finite State Machines (states, transitions, actions) to systematically analyze and structure
- Participants can implement FSMs in all four IEC 61131-3 programming languages (FBD, CFC, LD, ST) and select the optimal language for specific applications.
- Participants can develop FSMs with comprehensive safety systems, emergency handling, deadlock prevention, and error management for industrial applications.
- Participants can structure FSM code that is easy to debug, extend, and understand by other engineers, including professional documentation and testing strategie

Requirements
- Required Prior Knowledge: Basic knowledge of IEC 61131-3 programming languages (especially Ladder Logic, Function Block Diagram, or Structured Text) Understanding of variables, timers, and basic logic operations in PLC programming Experience with at least one PLC programming system (Siemens, Allen-Bradley, Schneider, etc.)
- Recommended Experience: 6-12 months of practical PLC programming experience Basic understanding of industrial automation systems Experience with simple control sequences
- Technical Requirements: Access to a PLC development environment (CodeSys, TIA Portal, Studio 5000, etc.) Computer with appropriate software installed Basic computer and software skills
- Note: This course is NOT suitable for absolute beginners. Participants should already have mastered basic PLC programming fundamentals.

Description
This course is about mastering Finite State Machines (FSM) in industrial automation - the secret behind robust, maintainable control systems used in elevators, manufacturing lines, and process plants worldwide. You'll learn to transform complex sequential control challenges into elegant, professional solutions that your colleagues will admire and maintenance teams will thank you for.

Discover the power of structured programming across all major IEC 61131-3 languages with real industry expertise.

FSMs are the backbone of modern industrial automation, yet many engineers struggle with implementing them properly. This comprehensive course bridges that gap by teaching you both the theoretical foundations and practical implementation techniques used in real industrial projects at companies like Merck, Siemens, and leading automation firms.

What You'll Master:

FSM Theory & Design- Understand states, transitions, and actions in industrial contextMulti-Language Implementation- Code professional FSMs in FBD, CFC, LD, and Structured TextTwo Industry-Proven Methods- SR-Flipflop approach for visual languages and CASE statements for complex logicComplete Elevator Project- Build a real-world control system with safety features, timeout monitoring, and emergency handlingProfessional Best Practices- Safety integration, deadlock prevention, error handling, and maintainable code structure

Perfect For:

PLC Programmers with 6 months to 3 years experience looking to advance their skills

Automation Engineers seeking structured programming methodologies

Electrical Technicians wanting to master sequential control systems

Engineers working with manufacturing equipment, material handling, or process control

Prerequisites:

Basic knowledge of IEC 61131-3 programming languages (Ladder Logic, FBD, or ST) and access to PLC development software (CodeSys, TIA Portal, etc.)

2+ hours of expert video instructionfrom a practicing automation engineer with Master's degree and 6+ years of hands-on experience at pharmaceutical, automotive, and robotics companies. Learn the techniques that are actually used in industry, not just academic theory.
