Automation In Conventional Lifts By using PLC

Abstract

This paper explains control of two floor elevator using PLC. With the increasing life standards and attention to human and with fastly development in engineering for building, the installation of elevators becomes an integral part of the infrastructure for the movement. IN this case one can make the better use of PLC for controlling of lifts which is efficient due to its flexibility, operational speed, reliability, easy to programming, security, and it is easy in implementing changes and minimizing errors. So, the control system is necessary for safe and smooth operation of the elevator. Hence for more efficient performance, more importance is given to the design of an elevator control system. Since output results must be produced in response to input condition within a given time, it is an example of a real time system. Ladder diagram programming is selected as it is easy to program the PLC
