Abstract :
This paper presents the control of elevator system using Siemens LOGO PLC. The system is programmed to drive a dc motor for forward and backward motoring mode with sensors at each floor, emergency STOP switch for maintenance purpose or to prevent any accident inside the lift & door switch for safety purpose. The system is also programmed to conserve energy by automatically switch off lights and fans of cabin when motor is in rest state for a specified duration of time. The software used in this elevator system is LOGO! Soft Comfort V7.0. This system can be used for learning the control strategies involved in elevator systems for educational purpose.
