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.

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

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.
