Automation Core: The Industrial Insider's Guide to PLCs & Smart Manufacturing

Automation Core — Beginner's Guide to Industrial Automation & PLC Programming

Industrial automation runs the world. Every factory, mine, and production plant depends on systems most people have never been taught to understand. Automation Core changes that.

This guide was written for anyone starting from zero — complete beginners with no technical background, electrical students, aspiring technicians, and career changers who want to understand how automation actually works before stepping into a course or onto a plant floor.

What's Inside

The guide covers the full foundation of industrial automation across ten structured chapters. It opens with how a real production line works — using a Coca-Cola bottling plant as the reference — before breaking down what a PLC is, what it consists of, and how it processes information. From there it builds systematically through digital and analog I/O, field devices including sensors and actuators, I/O addressing, data types and number systems, the accumulator model, PLC programming in both LAD and STL, timers, counters, edge detection, analog signal scaling, and program flow using jump instructions. Every chapter includes real-world examples drawn from mining, food processing, pharmaceutical, and water treatment applications, along with practice questions and worked solutions.

What You Will Be Able to Do

By the end of this guide you will understand how a PLC scan cycle works and how the CPU processes inputs and controls outputs. You will know the difference between digital and analog signals and how each is addressed and used in a program. You will be able to read and interpret NO and NC contacts both in the field and inside a program. You will understand how sensors and actuators connect to a PLC and what each device does in a live system. You will be able to work with data types, perform arithmetic and comparison operations using the accumulator, and scale real-world analog values correctly. You will write functional PLC programs in Ladder Diagram and Statement List, implement timers and counters, detect signal edges, and use jump instructions to control program flow. Most importantly, you will walk into your first PLC course or control panel room knowing exactly what you are looking at.

Who This Is For

Complete beginners with no prior technical knowledge. Electrical and automation students preparing for their first practical course. Technicians who work around automated systems but have never been shown how the programming side works. Anyone who wants a serious foundation before enrolling in hands-on PLC training.
