HMI Design and Intermediate PLC Programming

Modern industrial automation relies on the seamless communication between operators and machines. Understanding how to program programmable logic controllers (PLCs) and design effective Human-Machine Interfaces (HMIs) is essential for anyone entering the automation field. This written course guides you through foundational concepts to intermediate-level automation skills. You will learn to write structured control logic and design clear, user-friendly HMI screens that improve operational efficiency and safety. What you'll learn: Understand foundational PLC architecture, memory mapping, and basic programming instructions; Write intermediate control logic using ladder logic and modern structured text; Design clean HMI screens based on high-performance HMI principles for better operator awareness; Configure data tags and establish reliable communication between PLCs and HMIs; Implement basic troubleshooting techniques and alarm handling within your control programs; Apply modern industrial communication concepts, including OPC UA and basic network security. We begin with core definitions and industrial automation hardware basics before moving into intermediate programming logic. From there, you will explore layout best practices for HMI screens, learn how to map variables, and study structured troubleshooting techniques through detailed written examples. This course is designed for aspiring automation technicians, maintenance engineers, and beginners with a basic understanding of electrical concepts who want to build practical industrial programming skills. No advanced programming or hardware prerequisites are required. Start reading today to build your skills in modern industrial control and interface design.
