  1. Master/Slave networking configuration Alan Maynard Computer Electronic Networking

  2. OUTLINE • Motivation • Introduction • Problem statement • Proposed Solution • Results • Conclusions • Future Work

  3. MOTIVATION • After watching a special inside look on prisons I thought that I could make a PlC controlled based prison system • Since I really enjoyed the PLC glass and never got the time to try my hand at plc networking this was the perfect time.

  4. INTRODUCTION • While watching the special I saw a guard who had to walk down the cells on manually open each door with a key so at an instant he was out numbered anywhere between 8 to 16 inmates. With some sort of automated system the guard could distance himself from the inmates.

  5. PROBLEM STATEMENT • Network two PLCs and Demostrate the master and slave configuration. • Reduce the voltage to control a 5volt motor.

  6. PROPOSED SOLUTION • List steps taken to solve the problem such as: • Software (programming) • Networking (trail and error) • Assembly , building of the relay and gate to be controlled • Overall working conditions (does it all work together) • In each step there were troubleshooting and testing in each step.

  7. Proposed Solution • Small annoyances – the PLC ladder program I was using did from time to time act weird. If you got a no response from processor message you had to reboot the system.

  8. RESULTS • A network of two PLC’s • Master and Slave configuration • Implantation of a network of PLC’s Master Video Slave Video

  9. CONCLUSIONS • This system could be used in other workplaces where security is a must. • I learned how to network PLC’s • How to use the master/slave configuration • Use and wire relays

  10. FUTURE WORK • Security cameras • Forward and reverse direction of the motor used to open and close the gate • More PLC’s networked together.
