After a general introduction to the Allen-Bradley brand name for those who are new to the field of industrial automation and control, we will take a brief look back at the founding of the Allen-Bradley company and how they have been a going concern since the early 1900s.  We will move on to examine some of the significant contributions the company has made in the development of Programmable Logic Controllers (PLCs) dating as far back as the 1970s and how their subsequent contributions to PLC

Almost every building and facility relies on the automation of their mechanical and electrical systems, or the use of PLCs. In fact, PLCs are used across industries and are found in countless applications within factories, labs, and plants. Their use is only going to increase as more complex facilities undergo construction and factory floors expand.

Nowadays, with almost every service imaginable available to us on our smartphone, it’s difficult to envision what technology was like before the invention of a single controller. For factories and manufacturing plants, the invention of programmable logic controllers (or PLCs) revolutionized the industrial automation process, as its cutting-edge technology replaced a complicated system of electromagnetic relays with a singular controller.

1. Fourth Industrial Revolution or Industry 4.0

The Fourth Industrial Revolution, or often referred to as Industry 4.0, is currently underway in all aspects of the global economy. Industry 4.0 represents the ongoing automation of both the traditional manufacturing processes and other industrial practices across non-manufacturing sectors of the economy.
