Introduction
 Industrial Automation is an automation tool that uses PLC-SCADA interfacing.
 Programmable Logic Controller (PLC) is a small computer used for automation of
real-world processes, such as control of machinery on factory assembly lines.
 Supervisory control and data acquisition (SCADA) is a system that allows an
operator to monitor and control processes that are distributed among various
remote sites. SCADA is a system in which message or commands that are individual
are sends to the external world.

4. What is Automation
The word Automation is derived from Greek words “Auto”
and “Mation”
AUTO- SELF
MATION- MOTION
Automation is a set of technologies that result in
operation of machines without significance of human

5. Automation tools:-
Different types of automation tools exist
• HMI- Human machine interface
• SCADA- Supervisory control and data acquisition
• PLC- Programming logic controller
• Robotics

6. Advantage of Automation:-
 Accurate and consistent information
 Reduce Cost
 Faster fault identification
 Maintenance of quality & quantity
 Improved safety conditions
 Improved availability
 Increased production

7. Disadvantage of Automation:-
 Technology limits: Current technology is unable to
automate all the desired tasks.
 Unpredictable development costs
 Security threats
 High initial cost
 Increase in unemployment

8. Applications:-
 Automated highway system
 Automated manufacturing
 Home Automation
 Automated waste management
 Industrial automation
 Robotics
 Laboratory automation

9. PLC(Programmable logic controllers):-
 A PLC is solid state device which perform
sequential operation in industrial enviroment
and replace timer,counter,relay etc.
How it operates:-
PLC is designed to :-
 Read digital and analog input from various
sensors.
 Execute a user defined logic program.
 Write the resulting digital and analog output
values to various output elements,

10. WHY PLC
 To reduce human efforts
 To get maximum efficiency from machine
 Control machine with human logic
 To reduce complex circuitry of entire system

11. PLC(Major Components of a PLC)
PLC
OUTPUTINPUT
COMPUTER
SMPS
(UPLOADING)(DOWNLOADING)

12. Communication Cable:-
CPO3
PMO2
PLC software :-
a)Communication software:- Rslinx
b)Programming software:-
Rslogix 500 (Small, medium)
Rslogix 5000 (large)
c)Virtual Plc Software:-
Emulator 500

13. PLC Programming and it’s Elements:-

15. Areas of Application
 Manufacturing / Machining
 Food / Beverage
 Textile industry
 Aerospace
 Printing industry

16. Advantages
 Replacing Human Operators
 Beyond Human Capabilities
 Fast
 Easily programmed and have an easily
understood programming language
 Improves productivity
 Improves quality

17. o Initial cost are high
o There’s too much work required in
connecting wires
o Unemployment rate increases
o When a problem occurs, hold up time is
indefinite
o There is a difficulty with changes or
replacement
Disadvantages

18. SCADA (supervisory control and data acquisition)
 SCADA is real time industrial process control system used to
centrally monitor and control remote or local industrial
equipment such as motor, valve, pump, relay, etc

19. Why SCADA
 Saves Time and Money
 Less traveling for workers
 Reduces man power need
 Increases production efficiency of a company
 Cost effective for power systems
 Saves energy
 Reliable
 Supervisory control over a particular system

20. SCADA Softwares
 Wonderware INTOUCH
 Allen Bradley RSVIEW32
 Seimens WINCC
 GE Fanuc CIMPLICITY
 KPIT ASTRA

21. Wonderware INTOUCH
 Wonderware InTouch provides a single integrated view of all
your controls and information resources. Intouch enables
engineers, supervisors, operators and managers to view and
interact with the working of entire operation through
graphical representation of their production processes.

22. Components of SCADA
 Tags
 Recipe
 Security
 Database Connectivity
 Device Connectivity
 Dynamic Representation
 Alarms
 Trends
 Scripts
22

23. Tag’s
 It is the address of the memory location where
signals are being saved.
 We define a TAG in order to use it in the SCADA
software (Intouch wondeware)
 TYPES:
 1) Analog
 2)Digital
 3)Strings

24. Dynamic process graphic Real-time and
historical trending
Alarm Recipe management

25. Security Device
connectivity
Script for logic development Database connectivity

26.  The proposed model of Industrial Automation making machine is fully
automated and is controlled by using PLC and monitored by using SCADA
 The combination of PLC and SCADA provides an effective way to operate the
compressor. It overcomes many disadvantages in a relay based system
 It increases the safety and efficiency of the machines by turning off the
machine incase of any abnormalities , Thus protecting the machine and
increasing the life of the machine
