Full automatic washing machine control system has a variety of overall control, can use early analog circuit, digital circuit, or hybrid modulus. In recent years, with the rapid development of science and technology, the application of single-chip computer, PLC constantly going deeper, at the same time, drive traditional control test technology constantly updated. By German Siemens company's S7-200 PLC as the core controller for full automatic washing machine control system design, and designed the system structure, application instructions, ladder diagram, and the distribution of the input and output terminals. At the same time, according to the overall control requirements and characteristics of automatic washing machine control system, determine the PLC input and output allocation, and on-site commissioningKey words: PLCautomatic washing machine control system,PLC program design目录1 引言 22 全自动洗衣机控制系统总体控制方案确定 32.1 总体控制方案确定 32.1.1 控制系统的比较 32.2.2 洗衣机的 PLC 控制系统概述 33 ...
