What is Industrial Automation ..? Automation is encompassing virtually every walk of life. life. Automation solutions are required right from agricultural to space technology. technology.

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

Don’t Surprise

IT IS ALSO AUTOMATION AUTOMATION Processor (Brain)

Feedback(Eyes)

controlling unit(Hand)

Output action unit (Leg)

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

Thus ,we can define Automation Any systematic operation required intelligence and as well as monitoring action.

Limitation of Electronic Controller in a Industry In industry where large number of a Timer , Counter Counter,, PID, Relay, 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)

PLC (Programmable logical controllers)

Programmable Logic Controller 

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 operations in a plant.

History of PLC The PLC was invented i nvented 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 of  General Motors) Motors) issued a request for proposal proposal for an electronic replacement for hard-wired relay relay systems. The The winning  proposal came from Bedford Associates of Bedford, of Bedford, Massachusetts. Massachusetts. The first PLC, designated the 084 because it was Bedford Associates' Associates' eighty-fourth 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 C ontroller.. One of the people who worked on that  project was Dick Morley, Morley, who is considered to be the "father" of the PLC. .

Programming Progr amming In a PLC User have a multiple Choice for programming a PLC Ladder logic

Functional Block Diagram

Instruction List

Ladder Logic Programming Programming It is a easier way of Programming the PLC. So that Engineer must must be concerned only on procedure procedure and functional of the machinery design For this knowledge of basic Electronic Circuit is sufficient.

We can operate these Drive through Keypad , external Switch and also through PLC Induction Motor

Stepper Motor

Industrial Robotic is also the part of Automation Industry Industrial robotic is the finest example of  motion control system, 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

SCADA Supervisory Control and Data Acquisition Acquisition

Supervisory means Monitoring entire system through GUI representation of working Status ,of the entire system

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

Data Acquisition mean collecting data Information from Different controller, Sensor , Drives , Motor which are connected at distance through wire , Ethernet , wireless

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……..

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 monitor  Real Time operation and Historical Trend .

•

Alarm triggering which also used in this system , it trigger when trigger when certain task complete or sudden or sudden brake of a system. •

Recipe management ,it ,it provide the operator multiple choice for mixing the variety of chemical and solution. •

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

In Industry SCADA were designed on Computer  System , and display may be on computer screen, LCD Display or Projector 

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

HMI Human 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

Industrial Networking

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

Industrial Sensor It is basically are of two type Digital Sensor it has switching b/w ( 0,24V) Analog Sensor It is basically are of two type Current type analog Sensor (4mA—20mA) Voltage type analog Sensor (0—10V)

Advantage of Implementation of  Advantage automation in Industry Increase In Production Reliability in operation Flexibility in control techniques Flexibility in programming and reprogramming in the plant Large quantity of I/O s are connected Online/ 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 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 .

SCOPE OF AUTOMATION AUTOMATION

In the Research Lab such as CERN,NASA,ISRO,DRDO and etc Where very small unit of machine to the very very heavy heavy Machinery 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 ,thus sensor, controller & PLC are diploid there and monitoring & controlling is done from SCADA

In Industry and Research Lab
