UNIT I – INDUSTRIAL AUTOMATION
1 What is automation?
The word „Automation‟ is derived from greek words “Auto”(self) and “Matos” (moving).
Automation therefore is the mechanism for systems that “move by itself”. However, apart from
this original sense of the word, automated systems also achieve significantly superior
performance than what is possible with manual systems, in terms of power, precision and speed
of operation.
2 1 K1
2 Define “Role of automation in industry”

fundamental objective is may sell at higher price, in larger volumes with less production cost
and time.
2 1 K1
3 What is fluid power?
Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid
power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics
using a gas such as air or other gases
2 1 K1
4 What are the advantages of fluid power?
Fluid power systems eliminate the need for complicated systems of gears, cams, and levers.
Motion can be trans-mitted without the slack inherent in the use of solid machine parts.
The fluids used are not subject to breakage as are mechanical parts, and the mechanisms are not
subjected to great wear.
2 1 K1
5 State-Application of fluid power system.
Machinery operated by fluid power covers a wide range of applications in industry. Mobile
excavating equipment uses hydraulic systems. Automated production lines may use pneumatic
or hydraulic systems to position work pieces or move tools. Variable-flow control valves and
position sensors may be included in a servomechanism system for precision machine tools.
2 1 K1
6 Describe types of fluid power system.
There are generally two types of fluid power systems: hydraulics and pneumatics.
Hydraulic fluid power systems use liquids such as oil and water, and pneumatic fluid power
systems use neutral gases like air.

interconnections and Communications protocol for communication.
2 1 K2
12 Define SCADA.

of processes or product. Increased consistency of output. Reduced direct human labor costs and
expenses.
2 1 K5

cannot be easily automated, such as the production or assembly of products with inconsistent
component sizes or in tasks where manual dexterity is required. There are some things that are
best left to human assembly and manipulation.
2 1 K2
15 What is Automation strategy?
