【Abstract】This paper discusses the basic principle of PLC and the working
principle of automatic washing machine. Put forward the implementation using PLC simulation method to control the full-automatic washing machine operation. The method is based on the function of the automatic washing machine design of ladder
diagram, the ladder diagram input and to realize the simulation control PLC. Based on the GX DEVELOPER ladder diagram is designed, and a simulation was carried out. The simulation results show that the design meets the design requirements.This article mainly introduced the basic situation of the subject, tells the story of the overall mission of this curriculum design requirements, this paper introduces the general situation of Siemens PLC and mitsubishi PLC. As well as the overall design idea, that is, what needs to be done in the whole process of course design to meet the needs of the title. After verification in the end prove to be of this article designs to suit the requirements of the subject.
【Key words】 PLC; Ladder Diagram; Step Ladder Instruction.
