Metro is one of the public transports widely used all over the world. In this project we are going to apply PLC automation in METRO. This project is completely built to practice the sequence of operation in PLC Programming. It may completely vary in real time.

PLC Ladder Logic for Metro Automation
PLC Metro Ladder Logic Description
RUNG000
Human Checking – whether the human is having any restricted materials like Gun, bomb,Crackers ,Knife etc.
RUNG001
Language checking-whether the bags are having any Restricted material like petrol, Blood Bone etc.
RUNG 0002
After Taking ticket, she/he going to board metro from station A.
Rung 0003, 0004 & 0005
Five seconds given to People for boarding and door get closed after 5 seconds.
Rung 0006 & 0007
Metro train travelling from station A to B for 10 seconds
Rung 0008 & 0009
After reaching Station B, door gets open and ticket checking at exit door is happening.
(Ticket cost from Station A to B is 10/-)
Rung 0010, 0011 & 0012
Metro started running from station B to C.
Rung 13
After reaching Station C, door gets open and ticket checking at exit door is happening.
(Ticket cost from Station B to C is 20/-)
Rung 14
If the person is having ticket less than 20 rupee, It won’t allow the person to exit until he pay additional amount.
Same procedure the person who are all boarded in station B.
RUNG 0015, 0016 & 0017
Metro started running from station C to D.
RUNG 0018
After reaching Station D, door gets open and ticket checking at exit door is happening.
(Ticket cost from Station A to D is 30/-)
Rung 0019
If the person is having ticket less than 30 rupee, It won’t allow the person to exit until he pay additional amount.
Same procedure the person who are all boarded in station B and C
Program runs continuously until STOP PB is pressed
Conclusion:
The above explained concept is designed for practicing sequence of operation in PLC for Metro Automation Project.
