“Seeing once is better than hearing a hundred times, seeing a hundred times is better than realizing a hundred times, and being a hundred times enlightened is better than doing a hundred times.”
This is the author's favorite saying.
It means that seeing once is better than hearing a hundred times, realizing once is better than seeing a hundred times, and realizing something is ultimately better than experiencing it yourself.
When preparing for the Automation Equipment Industry Technician practical exam, it's often difficult to know where to start. Some may find PLCs unfamiliar, or perhaps they understand the theory but find it difficult to actually control the system manually.
This book was created for just those people.

Based on MITSUBISHI MELSEC PLC, it is composed mainly of PLC control practice examples tailored to the practical level of automation equipment industry engineers.
Rather than complex theories, we made it so that you can learn naturally by following along step by step through practice.
Although I couldn't include everything, I tried to include everything you need to take the first step toward the practical exam.
For any missing information, please refer to the official Mitsubishi Electric customer support website below.

In the future, we plan to continuously supplement application examples and materials that are more closely related to qualification exam practice and actual work.
I hope this book will serve as a reliable practical guide for those preparing to obtain the Automation Equipment Industry Engineer qualification.
When you feel lost and alone, I hope this book will be a solid start.
