Entire automatic washer production enormous convenience peoples life. The washer is the domestic electrical appliances industry does not only hit the profession which the price fights, passes through several year steady development, the domestically produced washer regardless of in quality or in function all with world leading horizontal synchronization. Looks over the washer market, the highly effective energy conservation, the province water, the province electricity, the environmental protection washer continuously occupy the dominant position in the market. According to the working principle of the full-automatic washing machine using PLC programmable controller control, illustrates the principle of PLC control method, characteristic and control characteristic of the washing machine. PLC is: the advantages of high reliability, less consumption, high adaptability, running speed, long service life, etc., in order to further improve the functionality and performance of fully automatic washing machine, avoid some disadvantages of traditional control, is proposed to use PLC to control the automatic washing machine is the subject. Fully automatic washing machine control system using the Siemens S7-200 se
