DESIGN AND IMPLEMENTATION of ELEVATOR CONTROL SYSTEM
This project is developed by using a Programmable logic controller (PLC) to control a 4-stories building elevator. The project system is running by calling each floor using the push buttons available at each floor and inside the car and the PLC would service your call as fast as possible. Floor sensors determine the current
position of the elevator car and determine its direction (up or down). The program downloaded in the PLC determines whether the car would go up or down according to the last visited floor. As a result the car moves up and down according to the issued call and the last visited floor. After the program was tested a
prototype developed and tested. The purpose of this project is for developing an effective elevator control system
