Lập trình PLC #1.1: Nhấn START rồi nhả… Tại sao máy vẫn chạy? (Mạch tự giữ PLC)| Ladder Logic

📺 PLC Programming Basics Lesson 1.1: Start/Stop Self-Holding Circuit | Siemens S7-200 PLC | Ladder Logic Tutorial In this video, you will learn how to program a Start/Stop control circuit (self-holding circuit), one of the most fundamental control problems in industrial PLC programming. This lesson is designed for beginners learning PLC programming, helping you understand the Ladder Logic design mindset so you can apply the same principles to other PLC platforms such as Siemens S7-1200, Mitsubishi, Omron, Delta, and more. 📖 ABOUT THE MAIN TRAINING BOOK This video is part of a structured training roadmap from the book: "PLC PRACTICAL PROJECTS – Industrial-Standard PLC Control System Design" 🔔 Note: Volume 1 of this material, which compiles more than 14 real industrial control problems, is currently in its final development stage. ➡ Subscribe to the channel to be the first to receive updates when the book is officially released! 📂 FILES & PROGRAM CODE FOR LESSON 1.1 (For those who want to practice along with the video) 👉 Download for free on GitHub: https://github.com/Electro-Industrial... Includes: LAD program files Hardware wiring diagrams (PDF) S7-200 programming reference materials 📍 VIDEO CONTENT 00:00 | Introduction to the PLC Practical Projects series roadmap 00:30 | Analysis of Start/Stop control requirements in industrial systems 01:58 | Accurate I/O hardware wiring diagram 02:33 | PLC configuration and simulation software setup 03:30 | Logic design thinking 03:46 | Ladder Logic (LAD) programming and simulation 05:53 | Safety principle analysis: STOP button must always use a Normally Closed (NC) contact 06:45 | Extended discussion of alternative programming approaches 💡 WHY FOLLOW THIS SERIES? This series does not only show you how to make a PLC program run, but focuses on the industrial-standard logic design mindset. By understanding the core principles, you will be able to adapt the logic to real industrial systems, instead of simply memorizing instructions. 📌 Next lessons in Chapter 1: Lesson 1.2: Using SET / RESET instructions (Stop priority) Lesson 1.3: Integrating an Emergency Stop circuit Lesson 1.4: Extended analysis & system design thinking summary 🔔 Don’t forget to Subscribe and turn on the notification bell so you won’t miss the upcoming lessons!
