Represented by :
Himansh Chourasiya

2. Content
• What is PLC
• Need of PLC
• Major components in PLC
• PLC input/ output component
• Programming languages & example
• Advantages
• What is SCADA
• Software & example

3. • PLC is stands for programabel logic controller
• PLC is a industrial computer that monitor input
makes decision based on it program and control
output automation process or machine
What is PLC

4. NEED OF PLC
• PLC is needed as to have following task:
• To reduce human effort
• To get the automation
• To get the automation in the process
• Controlling of equipment with one click
• To make the efficient use of digital electronic and
control system
• To reduce complex circuit of entire system

Major component in PLC

6.  Limit switch
 Pulse button
PLC input component

7. Relay’s
Led’s
PLC output component

8. PLC Programming Software
• RSLogix 500
Allen Bradley
• Modsoft
Mosicon
• Powerlogic
Square D

9. • PLC use ladder logic
• This is based on relay control schemes
• Relay contacts and coils, input and output lie on
“rungs”between the positive and groung rails
• Two basic relay symbol
LADDER LOGIC DIAGRAM

10. LADDER LOGIC EXAMPLE

11. • Large quantities of contact
• Lower cost
• Visual Observation
• Communication capability
• Reprogrammable
Advantages of PLC

12. • Operator/s,
• Engineer/s
Supervisory
• Monitoring ,
• Remote access
Control
• Sending data into different
sites through telemetry
Data
acquisition
What is SCADA
•Supervisory Control and Data Acquisition

13. SCADA Software
• By Rock well
RSView 32
• By InTouch
Wonder ware
• By Citect
Citect SCADA 5.42

14. • Data can be display at any time when user require
• The SCADA system provides on board graphical
information
• The SCADA system provides ability to operates critical
situation
Advantage of SCADA

15. SCADA example
