What is a Programmable Logic Controller, or PLC? If you’ve used a computer, and you’ve used an Arduino, Raspberry Pi, or any number of other microcontrollers, you might think that a computer based on the physical world is a relatively new concept. A digital input causes some sort of conditional logic to make something blink, your robot to move, a signal to be transmitted, or any number of other things. This type of logic has, in fact, been going on for quite some time in industry. In 1968, a man named Richard E. Morley proposed the Modular Digital Controller (MODICON) to a car manufacturer. This MODICON, or programmable logic controller (PLC), was used to replace complicated relays with virtual programmable relays, making machinery changes in industry much, much faster. This later became the commercial MODICON 084, which led to many more manufacturers making their own version. Here’s an article on the  history of the PLC  if you’d like more background.
