It application large-scale integrated circuits, Internet technology and communication technology development achievements, and gradually formed a has many advantages and mini, medium, large and super large specifications of the various series of products, from relay control system applied to monitor the many control area between computers.With the continuous development of society, building more and more high, but the elevator became the top of the building must equipment. Elevator from handle switch manipulate elevator, button control of elevator to the development of the present group control elevator, for high-rise transport made indelible contribution.PLC in elevator lift control of the application lies in its logical switch control function. Because of PLC has logic operations, counting and timing and data input and output functions. In the elevator lift process, all kinds of logic switch control and PLC good union, good realized to lift control.This paper introduces the development of the elevator in the elevator control and application of
