This document discusses industrial automation using programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) systems. It describes the Mecstech group which provides industrial automation training and services. PLCs are microprocessor-based controllers that can be programmed to automate industrial processes by replacing mechanical relays. SCADA systems allow users to create visualizations of industrial processes using data collected from PLCs to monitor and control the system remotely. The document provides an overview of PLC and SCADA components, programming, communication between the two, and benefits of automation.

4. What is AUTOMATION
• Making products under the control of
computers and programmable controllers is
known as automation.
• Manufacturing assembly lines as well as
stand alone machine tools and robotic
devices fall into this category.
• It is delegation of human control functions to
technical equipment for increasing the
productivity, quality, and increasing the
safety in working conditions thereby
reducing the manpower and cost.

5. INSUSTRIAL AUTOMATION
• Now a days, every small and large industry employ
automation.
• In manual control, an operator periodically reads the
process and adjusts the input accordingly. Quite
hectic!
• In automation control, measurements and adjustments
are done automatically on a continuous basis. Quite
convenient!

6. Types of Control Systems used in INDUSTRIAL
AUTOMATION
• PID controller based control system
• PLC based control system
• DCS based control system
• PC based control system

7. PLC(Programmable Logic Controller)
• It is microprocessor based solid state/industrial
computer that perform discrete or sequential logic.
• It was developed to replace mechanical relays,
timers, counters.
• The early PLC’s were used to reduce the
changeover time, wiring/re-wiring.
• The PLC programming procedures replaced the
rewiring a panel full of wires, relays, timers,
counters etc.

8. Advantages
• Reliability in operation.
• Flexibility in control and programming techniques.
• Online offline modifications.
• Small physical size, shorter project time.
• In house simulation and testing of project.
• Speed of operation.
• Ease of maintenance and troubleshooting.
• Ability to communicate and networking with computer system
in plant.
• Documentation and security.
• Designed to work in all types of industrial conditions.

UPLOAD
• DATA TRANSMISSION-SERIAL
• SYSTEM(PORT) PLC(PORT)
RS 232 DF port
• Baud Rate- 9.6 Kbps to 19.2 Kbps
• Driver softwares- RS Linx Classic, RS 232 & DF Drivers
• Programming software- RS Logix 500

13. PROGRAMMING the PLC
Programming language used: LADDER
language( ladder 2). The programming can be done
with simple contacts that simulate the opening and
closing of relays, counters, timers, shift registers
and other math operations.

21. SCADA
• Supervisory Control And Data Acquisition
• It is a software through which we can create visualization
of any industrial process.
• Earlier, PLC’s were programmed, download the program
in it and it used to run for years
• The problem- no one knew what’s happening inside the
PLC.
• Solution= PLC+SCADA

22. SCADA Software
• Wonderware- Intouch
• Rockwell- RS view32
• Siemens- winCC
• GE- Intellation

23. FEATURES OF SCADA
 Dynamic process graphic
 Alarm
 Database connectivity
 Real time trend and historical trend view
 Security
 Device connectivity

25. Real-time & Historical Trends

26. Alarms
 Every plant needs proper monitoring and control of
the process parameters.
 Alarms represent warnings of process conditions that
could cause problems, and require an operator
response

27. Security
 Every SCADA software has various levels of security
for securing the application by avoiding unauthorized
access.

28. Creating An Application InTouch
Steps in creating an application includes:
Create an application
Create the window in which application will run
Creating graphics images of different parts of our
process
Breathing life into graphics
