INTRODUCTION TO AUTOMATION• DEFINITION: THE USE OR INTRODUCTION OF AUTOMATIC EQUIPMENT IN A MANUFACTURING OR OTHER PROCESS OR FACILITY

In simple words: The process through which each and every work is carried by itself in any plant or system .

Used mainly for Higher productivity Superior quality of end products Effective usage of energy and raw materials Improved safety in working conditions

TYPES AND METHODSAUTOMATION CAN BE BROADLY CLASSIFIED INTO THREE CATEGORIES:• MICRO PURPOSE: USED IN SMALL PURPOSES LIKE DIGITAL WATCH, AUTOMATIC WASHING MACHINE STREET SOLAR LIGHTINGS

METHOD USING MICROPROCESSORS

• MINI PURPOSE: USED IN ROBOTICS, MACHINERIES LIKE CAT-SCAN, MRI, COMPUTERS, LIFTS, PRINTERS, CCTV CAMERAS

METHOD USING MICROCOMPUTERS

• LARGE PURPOSE: USED IN LARGE FACTORIES, PLANTS, INDUSTRIES, ROCKET LAUNCHING

METHOD PLC, SCADA, DSC

Development of Control System

Manual Control Hardwired Logic Control Electronics Control

Pneumatic Control Hydraulics Control PLC Control

PLC• PROGRAMMABLE LOGIC CONTROLLER• AN INDUSTRIAL COMPUTER THAT MONITORS INPUTS, MAKES DECISIONS

BASED ON ITS PROGRAM AND CONTROLS OUTPUTS TO AUTOMATE A PROCESS OR MACHINE

• THE AUTOMATION OF MANY DIFFERENT PROCESSES SUCH AS CONTROLLING MACHINES OR FACTORY ASSEMBLY LINES, IS DONE THROUGH THE USE OF SMALL COMPUTERS CALLED PROGRAMMABLE LOGIC CONTROLLER

WHY PLC???• REDUCE HUMAN EFFORTS

• MAXIMUM EFFICIENCY• REDUCE COMPLEX CIRCUITRY• ELIMINATE THE HIGH COSTS

UNDERSTANDING OF PLC
