PLC internal containment have the CPU of the CPU, and take to have an I/O for expand of exterior to connect a people39。 Second programming visual, simple。s application in its logical switch control function. Because PLC has the logic operation, counting and fixed time as well as data feeds output function. In the elevator rises and falls in the process, each logical switch control and the PLC very good union, very good have realized to the fluctuation the control. This article main discussion studies uses Simens in the S7200 PLC to carry on the control to elevator39。s unceasing development, the building is getting higher and higher, but the elevator became the highlevel building to the equipment. The elevator from the handle switch operation elevator, the pushbutton control elevator develops to present39。s serial products, applied to monitors between puter39。 R 2020 PCC as the elevator s main control system, pleted a 12storey station set selective control passenger elevators in the hardware and software control program design , the use of PCC its own has the logic operation and data processing functions, through appropriate increase in input / output point and the preparation of PCC control procedures, so that the system has run for the elevator fault monitoring and diagnosis functions, and further information on the PCC control system Elevator Remote in close connection with the machinery of largescale electrical machinery and electronic products. Mainly by the room, Wells Road, Car, door systems and electrical control 5 system. Acpanied by the development of the construction industry, to provide for the construction of the elevator up and down traffic and transport industries are developing rapidly. Elevator is not only an important link in the production of equipment, but also a life of work and the necessary equipment, can be expected that, with the
