Recently, DX (digital transformation), IoT (Internet of Things), and AI (artificial intelligence) have become a hot topic in the manufacturing industry.Then, when you want to specifically innovate or improve your business using DX, IoT, and AI, where should you start?I consider it a “manufacturing site”.This is because innovations and improvements in the “manufacturing site” are most directly linked to sales and profits.The manufacturing industry is a “company that makes things.”There is also a lot of manual work depending on the product to be manufactured.However, considering the era of declining birthrate and aging population in the future, automation of manufacturing using machines and robots will be promoted.PLCs (programmable logic controllers) that issue various operation commands to machines and robots and touch panels that enable the operation and monitoring of machines and robots are indispensable for automation technology in various manufacturing industries.This book carefully explains how to create a PLC program used in the manufacturing industry in an easy-to-understand manner.I hope that by gaining knowledge of PLC programming, which is the main product of FA (factory automation), it will be useful for improving on-site efficiency and workability, and for on-site reform and improvement utilizing DX, IoT, and AI.Also,「I’m going to use it for work, so I want to learn about PLC programs!」「There are many books on sequence control, but the PLC program is not written in detail.」「I read a book about PLC, but I don’t feel like I can make a program just by classroom lectures.」「I’m studying a PLC program, but the content was boring and I was frustrated on the way …」I want these people to have fun learning to the end.This book is created with three concepts. (The software uses the free trial version.)・Contents specialized for PLC programs.　⇒Deepen understanding of PLC programs.・Explaining things that are familiar to you as an example. ⇒Easy to imagine.・Actually create a program with exercises.　⇒Acquire practical skills.I hope that this book will help you to become an excellent PLC programmer who will be responsible for future factories and equipment.
