# PLC based Metro Automation Project

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 â€“ 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 wonâ€™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 wonâ€™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.
