This is an updated version of Lecture 01 Introduction to Relays and Industrial Control, a PLC Training Tutorial. It is part one of a two part lecture.
I'm going to introduce you to PLC basics for beginners. I'll talk about logic in simple systems, talking about the inputs and outputs logic systems have. I'll discuss why we need PLC s all in language absolute beginners will understand.
Today we are going to talk about the basics of a PLC, the workhorse of industrial automation.
The programmable logic controller, or PLC, is a special purpose computer. It has no display, no keyboard, no printer, no hard drive, and hides in the control panel out on the factory floor, but it is still a computer.
Initially, the PLC was a replacement for panels of relays, devices that turn on and off. Making a machine run using relays as logic was time-consuming and challenging, and making a change in the logic or the operation of the machine was almost as complicated as starting over.
