【正文】 arity in order to be tailored to different floors control of the calls that lifts quite satisfactory control results. In the design process through to lift the input and output nodes statistics to select appropriate models PLC During the software design of PLC control system, first of all , lift the whole control process deposition, it is divided into several different modules, then design for these modules Respectively, and finally regrouped together into a prehensive control system .The designs of used three control modes : passengers operation mode, the driver and manual mode of operation maintenance mode. And pared to the previous, the design of the lift with high reliability, control procedures simple and input and output terminals use fewer features.
