2. What is Automation?
•As the name suggests ‘Automation’ means to
perform automatic operations by means of
different kinds of machines.
•Automation is the use of control systems and
information technologies to reduce the need for
human work in the production of goods and
services.
•It is used to reduce human interference and and
efforts

3. Why Automation required in industry
Productivity
Quality Labour Cost
Plant
Total Automation Manufacturing
Competitivenes
Solution

4. History of “Automation”
Manual Control
Hard Wired Logic
control
Pneumatic control
Electronic control
using logic Gates
Programmable logic
controllers (PLC)

5. Components used in
“Automation”
•Sensors
•Transmitters
•Control System
 PLC
 DCS (Distributed Control System)
 PID Controllers (Proportional,
Integral & Derivative)
•Output Devices
 Actuators
Drives
Control Valves
Solenoid Valves

6. Tools of “Automation”
PLC (Programmable Logic Controller)
SCADA (Supervisory Control and Data
Acquisition)
HMI (Human Machine Interface)

7. What is PLC?
•PLC-programmable logic controller
• A programmable Logic controller is simply a
solid state industrial computer that perform
discrete or sequential logic in a factory
environment.
Advantages of plc:-
reliability and flexibility in operation.
Cost effective for controlling complex system
Small physical size, shorter project time
In-house simulation and testing of project
Security

8. PLC v/s COMPUTER
PLC
• Executes simple program
in milliseconds, scan time
is much smaller than 1/60
seconds.
• Objective is to make
yes/no,0/1 decisions.
• Special purpose device,
same program is
repeated continuously.
• No peripharals.
• Programmed using
ladder-logic
COMPUTER
• Possibly complicated
program, often timing is
not critical
• It may include floating
point, arithmetic, manip-
ulation of data
• General purpose,
possibly different
programs
• Need peripherals
• Programmed using high-
level lang.

9. What constitute a PLC?

10. Configuration of PLC
8 Analog Inputs 1
Analog Output
Up/Down Fast
Counter
Up Counter
Programming Terminal PC Connection
Unitelway Port for connection
of up to 5 Slaves
memory expansion port
communications port
TSX37-22
Built in display for I/O
(in-rack, AS-i)
I/O Modules

11. Inputs and Outputs of PLC

12. Power supply and memory of
PLC:-
A power supply of 120v is typically used to
drive the PLC, this power supply converts the
120v ac in to dc voltage of 5v.
RAM (Random Access Memory ),a volatile
memory is used for program storage
ROM (Read only memory),a non–volatile
memory is used for data storage.

13. Executing any signal in PLC

14. Programming in PLC:-
Languages used in PLC for the purpose of
programming are:-
•Ladder Language
•Functional block Diagram(FBD)
•Industrial list(IL)
•Drive Functional Block(DFB)
•Structured test language
Out of all the above, Ladder Logic is the most commonly
used. The ladder logic language id defined as:-
Logical continuity in a ladder rung occurs when there is a
continuous path of TRUE conditions from the left power
to the output instructions. When there is a logical
continuity and the output being energised.

15. Showing NO and NC switches in PLC

16. A view of the PLC working screen

17. SCADA(Supervisory control
and Data Acquisition)
•SCADA is real time industrial process control
systems used to centrally remote or local
industrial equipment such as motors, valves,
pumps, relays, etc
•It generally refers to an industrial system
(ICS).
•It is a production automation and control
system based on PCs.

18. Features of SCADA
Features of typical SCADA software:-
 Dynamic process graphic
 Real-time and Historical trending
 Alarms
 Recipe Management
 Security
 Device connectivity
 Script for logic development
 Database connectivity

19. Architecture OF SCADA

21. Analogous symbols of general elements
in SCADA

22. Requirements of SCADA

23. Applications of SCADA
•Production department
•Quality department
•Maintenance department
•Enterprise information
•Engineering department
•Manufacturing department

24. Application of SCADA in various plants
