This work represents a design and implementation of a elevator using PLC. It is a demonstration and a prototype for a three level elevator system control that is used as a transport device to move goods or people .The main objective is to design and implement an elevator using DC motor. It can be used to fetch car and move up/down according to input given by the programmer. Such a device can be used in industry, hotels, shopping centers, office building and airport.
This paper specifically deals with programmable logic controller (PLC) as the main controlling device to regulate all the activities of the elevator. In this we mainly focus with PLC ladder logic, thus this paper describes the application of PLC for elevator control system .This control system is described with the use of SO Machine V3.1 programmable logic controller to monitor and instruct a 3-floor elevator system. It can be displayed in any windows based computer system and operators can be warned when errors occur and correction must be performed. The program is executed in respond to the inputs entered.
The input devices are sensors, limit switch and push buttons. The output devices are a control panel which gives a message when the lift is reached to the desired floor. Hooter, dc motor and led display are the other output devices.
