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.
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
Automation tools:-
Different types of automation tools exist
• HMI- Human machine interface
• SCADA- Supervisory control and data acquisition
• PLC- Programming logic controller
• Robotics
Advantage of Automation:-
Accurate and consistent information
Reduce Cost
Faster fault identification
Maintenance of quality & quantity
Improved safety conditions
Improved availability
Increased production
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
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,
WHY PLC
To reduce human efforts
To get maximum efficiency from machine
Control machine with human logic
To reduce complex circuitry of entire system
IF input 4 OR input 5 have power
THEN energize output 0

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