Industrial Automation

MACHINE

CONTROL SYSTEM

INFORMATION TECHNOLOGY

Automation is basically the delegation of human control

function to technical equipment for

•Increasing Productivity• Increasing Quality

• Reducing Cost• Increasing Safety in working conditions

What is Industrial Automation ..?

Automation is encompassing virtually every walk of life.

Automation solutions are required right from agricultural to space technology.

Plant Automation is the necessity for the manufacturing industry to survive in today’s

globally competitive market

IT IS ALSO AUTOMATION

Feedback(Eyes)

Processor (Brain)

controlling unit(Hand)

When Human Operator can operate the machine ,taking Feedback of a Machinery performance and he can change or adjust according to requirement,that why it also called as Automation.

Thus ,we can define AutomationAny systematic operation required intelligence and as well asmonitoring action.

Limitation of Electronic Controller in a Industry

In industry where large number of a Timer , Counter, PID, Relay, Switches and etc ,which all makes the entire system costly and complicated .

Thus, there is need of One Controller which can monitor the entire system

And also generate delay and count a event

Easy to be program , modify whenever needed

All this feature are add up in a one controller PLC (Programmable Logic Controller)

Page 9: Summer training  plc & scada

History of Automation

• Manual control system

• Pneumatic control system

• Hard wired logic control system

• Electronic control using logic gate

• PLC (Programmable logical controllers)

Page 10: Summer training  plc & scada

A PLC is a micro processor based solid state / computerized industrial computer that performs discrete or sequential logic in a factory environment.

It was originally developed to replace mechanical relays, timers, counters.

PLCs are used successfully to execute complicated control operationsin a plant.

Programmable Logic Controller

Page 11: Summer training  plc & scada

History of PLC

The PLC was invented in response to the needs of the American automotive

manufacturing industry.

Programmable logic controllers were initially adopted by the automotive industry where

software revision replaced the re-wiring of hard-wired control panels when production

models changed.

In 1968 GM Hydramatic (the automatic transmission division of General Motors) issued a

request for proposal for an electronic replacement for hard-wired relay systems. The winning

proposal came from Bedford Associates

of Bedford, Massachusetts.

The first PLC, designated the 084 because it was Bedford Associates' eighty-fourth project,

was the result. Bedford Associates started a new company

dedicated to developing, manufacturing, selling, and servicing this new product:

Modicon, which stood for Modular Digital Controller. One of the people who worked on that

project was Dick Morley, who is considered to be the "father" of the PLC. .

Programming In a PLC

User have a multiple Choice for programming a PLC

Ladder logic Functional Block DiagramInstruction List

Page 14: Summer training  plc & scada

Ladder Logic Programming

It is a easier way of Programming the PLC.

So that Engineer must be concerned only on procedure and functional of the

machinery design

For this knowledge of basic Electronic Circuit is sufficient.

For Example

Motion Control System

VFDInduction Motor

Stepper DriveStepper Motor

Servo Drive Servo motor

We can operate these Drive throughKeypad , external Switch and also through PLC

Page 18: Summer training  plc & scada

Industrial Robotic is also the part of Automation IndustryIndustrial robotic is the finest example of motion control system, One robot required one controller for the specific operation but when multiple robot working together thus we required no. of PLC connected together by Master PLC, so that entire process can be synchronized

Page 19: Summer training  plc & scada

SCADA

Supervisory Control and Data Acquisition

Supervisory means Monitoringentire system throughGUI representationof working Status ,of the entire system

Control means Controlling the entire System such as ON/OFF operation ,Speed controlling, temperature Controlling

Data Acquisitionmean collectingdata Information from Different controller, Sensor , Drives , Motor which are connected at distance through wire , Ethernet , wireless

Page 20: Summer training  plc & scada

PLC is just like a Black Box, internal operation of its

user can`t see until the entire process complete or halt the

System…Thus we required GUI(Graphical User Interface)

Representation of the entire process……..

Page 21: Summer training  plc & scada

Main feature of SCADA

•GUI is designed by simple Drag and Paste concept.

•Tagging and Coding is done by considering programming bit .

•On SCADA ,we can monitor Real Time operation and Historical Trend .

•Alarm triggering which also used in this system , it trigger when certain

task complete or sudden brake of a system.

•Recipe management ,it provide the operator multiple choice for mixing the

variety of chemical and solution.

Page 22: Summer training  plc & scada

We can also monitor the Real time operation and the process on Graph .

Page 23: Summer training  plc & scada

In Industry SCADA were designed on Computer

System , and display may be on computer

screen, LCD Display or Projector

Here we can see, all the sensor , chemical tank, filling process , temperature ,ON /OFF status of Motor .All this thing, it has being monitor on the PC screen and big LCD Screen or projector.

Page 24: Summer training  plc & scada

HMIHuman Machine Interface

It have some major feature of SCADA ,HMI it is basically a control display screen were operator can monitor and control the machinery and it is portable and can easily installed on the Machine itself

HMI It was designed for the specific task operation on the machine and SCADA is for entire Plant operation

Page 25: Summer training  plc & scada

Industrial Networking

Eternet, Device net,Modbus , Profibus cable are used for connecting entire Controller , Sensor , PLC and SCADA

Page 26: Summer training  plc & scada

Industrial Sensor

It is basically are of two type

Digital Sensorit has switching b/w ( 0,24V)

Analog SensorIt is basically are of two typeCurrent type analog Sensor

(4mA—20mA)Voltage type analog Sensor

(0—10V)

Advantage of Implementation of automation in Industry

Increase In ProductionReliability in operation Flexibility in control techniques Flexibility in programming and reprogramming in the plant Large quantity of I/O s are connectedOnline/ offline modifications Cost effective for controlling complex systems In-house simulation & testing of project Speed in operation Ability to communicate with computer systems in the plant. Ease of maintenance / troubleshooting

SCOPE OF AUTOMATION

In Aeronautic and Space Application, where large amount of a Controlling unit are used for connecting different device that are working systematic manner

Smooth functioning of the Delhi Metro train is a example of a motion control system .

Page 29: Summer training  plc & scada

SCOPE OF AUTOMATION

In the Research Lab such as CERN,NASA,ISRO,DRDO and etc Where very small unit of machine to the very heavy Machinery Unit designed are interlink together , A to Z controlling in came under industrial Automation.

In Heavy industry such as Steel ,Automobile , and Food industry where the man are not able to work in a such hostile condition ,thus sensor, controller & PLC are diploid there and monitoring & controlling is done from SCADA based control room

Page 30: Summer training  plc & scada

Industrial Automation is the End Consumer of the

Engineering field.

In Industry and Research Lab

All the Mechanical machinery from small to large such as Hydraulic system, pneumatic system, Induction motor are consumes in the Automation industry

Relay ,Contactor and large Amount of Switch Gear(MCB,MCCB,OLR ,Push Button) are also consumes in this industry

Industrial sensor (Proximity ,IR Sensor , Level sensor) & instrument (Pressure Switch , limit Switch, Flow Meter)are also consumes in this

Embedded product such counter , timer, PID controller and electronic Regulator and PLC are also consumes in the automation

Mechanical

For connecting different device , controller , PLC and SCADA so that they can communicate with each other thus Industrial networking requirement is essential
