3.  A programmable
logic controller (PLC) is a
digital computer used for automation of
electromechanical processes, such as control
of machinery on factory assembly lines,
control of amusement rides, or control of
lighting fixtures.

11. • CPU: Its the unit containing the microprocessor.
• Power supply unit:Its needed to convert the
mains A.C. voltage to low D.C. Voltage(Normally
Internal)

12. • Input-output sections:
are where the processor receives information from
external devices and communicates information to
external devices.

13. • Expansion Modules:
The S7-200 PLCs are expandable. Expansion
modules contain additional inputs and outputs.
These are connected to the base unit using a
ribbon connector.

14. • Memory unit: is where the
program is stored that is to
be used for control actions.
• Programming
device:
is used to entered the
required program into the
memory of the processor.

18. PLC Operation:
1.The PLC program is executed
as part of a repetitive process
referred to as a scan.
2. Scans:- :Left to Right
Top to Bottom
3.Scan cycle:- 800-1000scan/sec

19. Example:
The Ladder Diagram

20. Selecting a PLC:
Criteria:
 Number of logical inputs and O/P.
 Memory.
 Number of special I/O modules
 Scan Time.
 Communications.
 Software.

21. HMI (Human Machine Interface) is a medium for information exchange
and mutual communication between electromechanical system's and
the user. It allows the user to complete settings through touchable
images or keys on the user-friendly window. This not only offer's fast
and convenient control of manufacturing automation, but also has
replaced traditional controlling panel's which need extensive wiring

23. Introduction (What Is SCADA?)
1.Stands for supervisory control And data
acquisition.
2.SCADA systems are used in industrial
processes: steel making, power generation
(conventional and nuclear) and distribution.
3.There Are 4 Components In the SCADA
System.

24. SCADA Components

Field Instrumentation.
 Sensors, devices to control.

Remote Terminal Units.
RTU Vs. PLC

Communications Network.


Equipment needed to transfer data to and from different sites
Central Monitoring Station
Collecting information gathered by the remote stations to
generate the necessary action


Designed for extreme
industrial environments
Can operation in high
temperature and humidity
High immunity to noise
Integrated command
interpreter (proprietary)
No secondary memory
available (in the PLC)
Optimized for Single task
 Computer
Designed mainly for data
processing and
calculation
 Optimized for speed
 Can’t operate in extreme
environments
 Can be programmed in
different languages
 Lost of secondary
memory available
 Multitasking capability

29. Why PLC ?
 The controller is designed in modular form, so
that sub-assemblies could be removed easily for
replacement or repair.
 The control system needs the capability to
pass data collection to a central system.
 The system becomes reusable.
 The method used to program the controller is
simple, so that it can be easily understood by
plant personnel.

30. Advantages of PLCs:
 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

31. Areas of Application
 Manufacturing/Machining
 Food/beverage
 Metals
 Power
 Mining
 Petrochemical/Chemical
