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.
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!
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
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.
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.

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
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.

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

Real-time & Historical Trends
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 operatorresponse
Security Every SCADA software has various levels of security
for securing the application by avoiding unauthorizedaccess.
Creating An Application InTouch
Steps in creating an application includes:
