// ROBOTICS AND SMART FACTORIES TERM
PLC
An abbreviation for Programmable Logic Controller, a specialized industrial computer used to automate manufacturing processes.
TECHNICAL DEFINITION
A PLC, or Programmable Logic Controller, is a ruggedized industrial digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines or robotic systems, by continuously monitoring input devices and making decisions based on its programmed logic.
BACKGROUND
The Fourth Industrial Revolution, also known as 4IR, Industry 4.0 or the Intelligence Age, is a neologism describing rapid technological advancement in the 21st century. It follows the Third Industrial Revolution. The term was popularized in 2016 by Klaus Schwab, the World Economic Forum founder and former executive chairman, who asserts that these developments represent a significant shift in industrial capitalism.
