Mastering PLC Programming

Overview of this book

Object-oriented programming (OOP) is a new feature of PLC programming that has taken the automation world by storm. This book provides you with the necessary skills to succeed in the modern automation programming environment. The book is designed in a way to take you through advanced topics such as OOP design, SOLID programming, the software development lifecycle (SDLC), library design, HMI development, general software engineering practices, and more. To hone your programming skills, each chapter has a simulated real-world project that’ll enable you to apply the skills you’ve learned. In all, this book not only covers complex PLC programming topics, but it also removes the financial barrier that comes with most books as all examples utilize free software. This means that to follow along, you DO NOT need to purchase any PLC hardware or software. By the end of this PLC book, you will have what it takes to create long-lasting codebases for any modern automation project.

Technical requirements

For this chapter, all you will need is a copy of CODESYS installed and working on your machine. The examples for this chapter can be found at the following URL:

https://github.com/PacktPublishing/Mastering-PLC-programming/tree/master/Chapter%2010.

As is standard for this book, you should download the code. Some of the code for this chapter will be a bit different from that of the other chapters. Much of the code in this chapter will be more akin to pseudocode that follows the IEC 61131-3 Structure Text syntax, as much of the code in this chapter will be used to merely demonstrate concepts. However, working examples will be provided, and these examples will either be noted or have screen outputs.
