Primary focus is on using programmable logic controller to build the elevator model. T
3、o control the motion of the elevator through various levels DC geared motor is used. Push buttons are used to give signal to the elevator to come to the desired floor, traversing up and down. Moreover DC relays are used as switches, not protective devices, to drive the motor in clockwise and anticlo

INTRODUCTION Due to rapid population growth in cities and presence of multi-storied buildings, the need of elevators is increasing. With better standard of living, the installation of elevators has become an integral part of the modern world scenario, for the movement of goods a
