Part 1 – An Introduction to Advanced PLC Programming

This section of the book is designed to give you an in-depth look at advanced Structured Text programming and general software development principles. The goal of this section is to teach you how to write PLC programs using advanced programming techniques. The section explores advanced elements of Structured Text, complex variables such as variable lists and arrays, and finally, debugging so you can learn how to properly debug PLC code. In short, this section will lay the framework for the more advanced concepts that are explored throughout this book.

This part includes the following chapters:

• Chapter 1, Software Engineering for PLCs
• Chapter 2, Advanced Structured Text — Programming a PLC in Easy-to-Read English
• Chapter 3, Debugging — Making Your Code Work
• Chapter 4, Complex Variable Declaration — Using Variables to Their Fullest
