As smart factories and advanced technology become more prevalent, the demand for PLC programmers with expertise beyond ladder logic is growing. This book introduces a new approach to PLC programming, preparing you for future challenges by exploring automation programming through computer science and text-based programming. The book begins by exploring the basic components of PLCs and how they integrate with other modules, giving you a clear understanding of system functionality. As you progress, you'll delve into PLC program execution, learning about flow and essential components for effective programming. Next, you'll understand program design with pseudocode and flowcharts, vital for planning programs. You'll then explore Boolean logic intricacies, harnessing logical functions and truth tables for precise control statements. Later, you'll delve into structured text, gaining a comprehensive grasp of syntax and features crucial for efficient programming. The journey continues with a focus on advanced topics like cybersecurity in PLC systems and leveraging generative AI (GenAI), such as ChatGPT, to enhance productivity. By the end of this book, you’ll be able to design real-world projects using pseudocode and flowcharts, and implement those designs in structured text.
