3. Introduction of automation
Automation is any sensing, detection, information-processing,
decision-making, or control action that
could be performed by humans but is actually
performed by a machine.
Automation is the use of control systems and
information technologies to reduce the need for
human work in the production of goods and services.
In the scope of industrialization, automation is a step
beyond mechanization

4. Advantage of automation
• Increased throughput or productivity.
• Improving operating efficiencies.
• Improved quality.
• Increase consistency of output.
• Reduced direct human labour costs and
expenses.
• Providing outstanding customer service.

5. VFD
• A Variable Frequency Drive (VFD) is a type of motor
controller that drives an electric motor by varying the
frequency and voltage supplied to the electric motor.
• Other names for a VFD are variable speed
drive, adjustable speed drive, adjustable frequency
drive, AC drive, microdrive, and inverter.
• VFDs are used in applications ranging from small
appliances to the largest of mine mill drives and
compressors.

7. Working of VFD
• The first stage of a Variable Frequency AC
Drive, or VFD, is the Converter.
• The VFD dc bus has a dc voltage with an AC
ripple. We can get rid of the AC ripple on the
DC bus by adding a capacitor.
• Now the inverter converts the DC back to AC
of required frequency.

8. Advantages of VFD
• VFDs allow you to match the speed of the
motor-driven equipment to the load
requirement.
• By operating motors at the most efficient
speed for your application, fewer mistakes will
occur, and production levels will increase.
• equipment will last longer and will have less
downtime due to maintenance when it’s
controlled by VFDs

12. PLC
A PLC (i.e. Programmable Logic Controller) is a device that
was invented to replace the necessary sequential relay circuits
for machine control.
The PLC works by looking at its inputs and depending upon
their state, turning on/off its outputs.
The user enters a program, usually via software, that gives the
desired results.
PLCs are used in many "real world" applications. Almost any
application that needs some type of electrical control has a
need for a PLC.

PROCESSOR
Provides intelligence to command and govern the activities of the
entire PLC systems.
PROGRAMMING DEVICE
used to enter the desired program that will determine the sequence
of operation and control of process equipment or driven machine.

17. Advantages of PLC:
 Less wiring.
Wiring between devices and relay contacts are
done in the PLC program.
Easier and faster to make changes.
Trouble shooting aids make programming easier
and reduce downtime.
Reliable components make these likely to operate
for years before failure.

19. SCADA
 SCADA stands for “Supervisory Control and Data Acquisition”.
 Purely Software Package that is positioned on top of hardware.
SCADA refers to a system that collects data from various sensors at a
factory, plant or in other remote locations and then sends this data to a
central computer which then manages and controls the data.
SCADA focuses on gathering and circulating the right amount of
system information to the right person or computer within the right
amount of time.
