Traditional domestic elevator control from the first relay, a contactor. It is not only poor in the reliability, high cost, high failure rate shortcomings, but also in layers increases, changes to the wiring and installation of manufacturing has brought many unchanged. If the control by PLC to address the above shortcomings. the design of the PLC as a tool to the elevators for various operating control. Elevator on the first four parts of the hardware analysis, the need to see what kind of switches, motors, lights, etc. Then, the control panel draw maps, plans, under the control panel is estimated to I / O points, so certain selected models, and then softwaredesign, write flowchart, ladder diagram, write statements. Finally,debugging and look at the feasibility of this procedure.Key words: PLC control system Elevator relay contactor
