PLC PROGRAMMING

Introduction

PLC PROGRAMMING

In the previous 'Everything about factory automation' book, we had an introduction to the basics of the factory automation. We came to know that a PLC is an inevitable part of an industrial automation. An industry cannot be automated without the aid of a PLC.

There are a number of PLC manufacturers available in the market each PLC has its different aspects. Even though they are dissimilar, they work on the same principle.

In this book, we will dig deeper into the basics and advanced PLC programming. We are going to learn about Allen Bradley, Siemens, and Mitsubishi PLC, their programming software with real-world examples.
