1 Introduction

A programmable logic controller (PLC), also known as a programmable controller, serves as a computer for industrial manufacturing. PLCs bring flexibility (ability to reprogram quickly) with reliability (minimal power down and maintenance) and ease of use in a standalone factory environment. Originally conceived for the auto manufacturing industry in the 1960s to replace hard-wired options such as relays and enable programmable, real-time control of equipment, PLCs are now ubiquitous in the manufacturing industry. They are a necessary component of factories of today and of future, and instrumental to safety, reliability and continuous operation.

Over the past five decades, PLCs have evolved to meet the ever-growing needs of more automation and more data handling. This includes miniaturization, deterministic communication, moving to distributed control systems and cloud connectivity.
