UNDERSTANDING PROGRAMMABLE LOGIC CONTROLLERS
Modern industrial automation systems are smarter and more advanced than ever before. But have you ever wondered how did they get this way? What gives them the power and capability? What drives them? The answer is the PLC. So now the questions are ‘What does PLC stand for?’;‘What does a PLC do?’ Read on for a detailed introduction to PLCs. What is a PLC? First let’s learn the PLC full form . PLC stands for Programmable Logic Controller. According to Wikipedia, “A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.” The PLC or Programmable Logic Controller is the heart and brain of industrial automation.It is a specialised computer control unit th...
