【正文】 ich was developed to achieve these objectives, the most important ways. The rapid development of industrial automation technology for the elevator control system technology update provides the material base. Continue to be the most advanced areas of industrial control technology and products introduced to the elevator control, elevator industry, technology development is the most important and effective article programmable puter controller PCC, the puter technology, munication technology, automatic control technology for the integration of new areas of industrial control industrial control device, used in the lift China s elevator industry, technology status and development trend of the detailed analysis, based on this paper, B amp。s material and cultural life and the car will be has bee one of the important transportation equipment. The design mainly PLC (PLC) and puter application to the elevator control system, and to fivestory elevator as an example to plete a single lift PLC program control system design, position and modular program design . Mitsubishi FX2N through puter munications and to achieve operation of the elevator control system PLC (programmable controller) takes one industrial control microputer, it is convenient by its programming, simplicity of operator its merits and so on high controllability, obtained the widespread application particularly in the industrial production process. It applies the large scale integrated circuit, the miniature machine technology and the mechanics of munication development achievement, formed gradually had many kinds of merits and miniature, medium, largescale, the ultralarge type and so on each kind of specification39。s many control domain from the blackwhite control system. Along with society39。s group control elevator, has made the indelible contribution for the highlevel transportation. PLC mainly manifests in the elevator cuing control39。s fluctuation, forms the lift control system. PLC Introduction Programmable controller is the first in the late 1960s in the United States, then called Plc programmable logic controller (ProgrammableLogicController) is used to replace relays. For the implementation of the logical judgement, timing, sequence number, and other control functions. The concept is presented Plc General Motors Corporation. Plc and the basic design is the puter functional improvements, flexible, generic and other advantages and relay control system simple and easy to operate, such as the advantages of cheap prices bined controller hardware is standard and overall. According to the practical 6 application of target software in order to control the content of the user procedures memory controller, the controller and connecting the accused convenient target. In the mid1970s, the Plc has been widely used as a central processing unit microprocessor, import export module and the external
