3. What is Automation?
– As the name suggests ‘Automation’ means to perform automatic
operations by means of different kinds of machines.
– Automation is the use of control systems and information
technologies to reduce the need for human work in the production
of goods and services.
– It is used to reduce human interference and efforts

8. What Is PLC?
– PLC-programmable logic controller
– A programmable Logic controller is simply a solid state industrial co
mputer that perform discrete or sequential logic in a factory environme
nt.

9. 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. 9

14. Power Supply And Memory Of PLC:-
– A power supply of 120v is typically used to drive the PLC, this power
supply converts the 120v ac in to dc voltage of 5v.
–RAM (Random Access Memory),a volatile memory is used for
program storage.
–ROM (Read only memory),a non–volatile memory is used for data
storage.

16. Processor And Programming Device
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. Programming in PLC:-
Languages used in PLC for the purpose of programming are:-
– Ladder Language(LL)
– Functional block Diagram(FBD)
– Industrial list(IL)
– Drive Functional Block(DFB)
– Structured test language
Out of all the above, Ladder Logic is the most commonly used.

20. Features of SCADA
– Features of typical SCADA software:-
» Dynamic process graphic
» Real-time and Historical trending
» Alarms
» Recipe Management
» Security
» Device connectivity
» Script for logic development
» Database connectivity

23. 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 operator response

24. Security
Every SCADA software has various levels of security for securing the application by
avoiding unauthorized access.
