【正文】 st .The paper selectsＯＭＲＯＮ pany’s Ｃ 200HE series PLC, introducing parts of signal hookup of the elevator control system and explaining the function of the control cabi. Lastly the automation programming is introduced. Simulated experiments enunciates that the design method is viable. It can make the personnel of the industry management center to longdistance monitor and control the elevator in control center, to connect the elevator control system with intelligence building industry management system by Ether or specialpurpose work such as Lon elevator working state can also be timely not only can realize scientific centralized management of the elevator, but also can lower the elevator maintenance cost etc. It is one of the developing direction of intelligence building elevator control system. Keywords: PLC。 intelligence building。 working principle。 When the elevator is descending, the descending demands are prior to other demands. The Sequential Function Chart (SFC) is adopted during the boxes to form elevator’s executive circuitry design. It is a method specially used in industrial sequential control. The SFC method can describe the system’s working procedure in great detail. For example there is a three layers intelligence building. A subprogram, the calling from the third floor as elevator in the first floor, is shown in Fig. 3 with SFC. When all SFC are drawn and I/O address lists are presented, we can convert the SFC to Ladder Diagram (LD).Considering the strict demands for time and for locked each other ,we introduce working bits to remember working steps. We should write out the working bits control program, which can link together each step and make the previous step as the next step restriction condition. Thus the actual outputs are the logic bination of these working steps. Ⅴ . Conclusion The system program has been debugged pletely at present. Simulated experiment enunciates that the design method is viable. Application of PLC in the elevator control system is an effective method. It can make the personnel of the industry management center to longdistance monitor and control the elevator in control center, to connect the elevator control system with intelligence building industry management system by Ether or specialpurpose work such as Lon Works. The elevator working state can also be timely watched. These not only can realize scientific centralized ma
