WHAT IS AUTOMATION ? Making products under the control of computers

and programmable controllers is known as automation.

Manufacturing assembly lines as well as stand alone machine tools and robotic devices fall into this category.

It is delegation of human control functions to technical equipment for increasing the productivity, quality, and increasing the safety in working conditions thereby reducing the manpower and cost.

AUTOMATION TOOLSDifferent types of automation tools exist are :-

HMI - Human Machine Interface.

DCS - Distributed Control System.

SCADA - Supervisory Control and Data Acquisition.

PLC - Programmable Logic Controller.

12

WHY PLC ? To Reduce Human Efforts .

To Get Maximum Efficiency From Machine And Control Them With Human Logic .

To Reduce Complex Circuitry Of Entire System .

To Eliminate The High Costs Associated With Inflexible, Relay-controlled Systems.

WHAT IS PLC ?

A Programmable Logic Controller, Or PLC For Short, Is Simply A Special Computer Device Used For Industrial Control Systems. They Are Used In Many Industries Such As Oil Refineries, Manufacturing Lines, Conveyor Systems And So On.

Plc Implements Logic Control Functions By Means Of A Program.

Supervisory Control & Data Acquisition Systems

WHY SCADA?Previously Without SCADA Software, An Industrial Process Was Entirely Controlled By PLC, CNC , PID & Micro Controllers Having Programmed In Certain Languages Or Codes.

These Codes Were Either Written In Assembly Language Or Relay Logic Without Any True Animation That Would Explain The Process Running.

It Is Always Easy To Understand The Status Of The Process If It Is Shown With Some Animations Rather Then Written Codes.

Hence Scada Software Came To Existence And With Some Exclusive Features It Became Internal Part Of Automation System

WHAT IS SCADA?SCADA Stands For Supervisory Control And Data Acquisition. As The Name Indicates It Is Not A Full Control System, But Rather Focuses On The Supervisory Level.A SCADA Program Normally Runs On A PC And Communicates With External Instrumentation And Control Devices. It’s An Optional Device Used In Automation For Continuous Monitoring.
