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”

The major role an automation industry is essentially doing systematic economic activity. The

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.

2 1 K2

7 How to do “Test automation” in automation field?

Automated testing tools are capable of executing tests, reporting outcomes and comparing

results with earlier test runs. Tests carried out with these tools can be run repeatedly, at any time

of day. The method or process being used to implement automation is called test automation in

automation field.

architecture based on PLCs and/or PACs (Programmable Automation Controllers) is the best

approach to total plant automation.

2 1 K4

11 Difference between PLC and DCS.

PLC is frequently used to synchronize the flow of inputs from sensors and events with the flow

of outputs to actuators and events. This leads to precisely controlled actions that permit a

tight control of almost any industrial process.

DCS typically uses custom designed processors as controllers and uses both proprietary

interconnections and Communications protocol for communication.

2 1 K2

12 Define SCADA.

SCADA is an acronym for Supervisory Control and Data Acquisition. SCADA generally refers

to an industrial computer system that monitors and controls a process. In the case of the

transmission and distribution elements of electrical utilities, SCADA will monitor substations,

transformers and other electrical assets

2 1 K1

13 Benefits of automation in production process.

Improved quality or increased predictability of quality. Improved robustness (consistency),

of processes or product. Increased consistency of output. Reduced direct human labor costs and

expenses.

2 1 K5

14 Describe some disadvantages of automation.

Technology limits. Current technology is unable to automate all desired tasks. Some tasks

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?

The Automation Test Strategy defines a framework for reusable automated scripts and

the approach planned by the QA Mentor Automation Expert Department. It outlines the overall
