The Evolution of PLCs in Industrial Automation: A 2,000-Year Journey

Industrial automation has undergone a remarkable transformation over the decades, and at the heart of this evolution lies the Programmable Logic Controller, or PLC. In this comprehensive exploration, we will delve into the fascinating history of PLCs in industrial automation. From their humble beginnings as relay-based control systems to their current status as sophisticated digital control units, we will trace the journey of PLCs through the years, highlighting key milestones, technological advancements, and the profound impact they’ve had on modern industry.

Early PLC System

Chapter 1: The Birth of PLCs

The concept of automation in industrial processes can be traced back to the early 20th century when factories sought ways to improve efficiency and reduce human error. Before PLCs, control systems relied on cumbersome and limited relay logic. It was not until the late 1960s that the first true PLC emerged.

In 1968, a team at Bedford Associates, led by engineer Dick Morley, developed the first PLC, known as the “084.” This revolutionary device aimed to replace traditional hardwired relay systems with a digital alternative. The 084 was a significant departure from earlier control mechanisms, introducing the concept of programming controllers through software, marking a turning point in industrial automation.

Chapter 2: PLCs in the 20th Century

Throughout the 20th century, PLCs underwent significant advancements and refinements. Microprocessor technology, which was rapidly evolving at the time, played a pivotal role in the development of PLCs.

The 1970s saw the emergence of major PLC manufacturers, including Allen-Bradley, Siemens, and Mitsubishi, who introduced their own versions of programmable controllers. These manufacturers began producing PLCs with increased processing power and expanded memory, enabling them to handle more complex tasks and accommodate a broader range of applications.

In the 1980s, PLCs started integrating communication capabilities, such as serial and Ethernet communication. This allowed PLCs to communicate with other devices and systems, paving the way for more extensive automation networks and remote monitoring.
