Type selection of PLC made in this paper, the author introduces the characteristics of S7-200 CPU226. Made on the propagation of the module is discussed in detail. To the corresponding selection, sensor made corresponding allocation of input and output point. Make a set of motor fault diagnosis system based on PLC.In this paper, the motor fault diagnosis system based on PLC, the hard software design has made a detail, the fault diagnosis system of the process diagram and the man-machine interface, making the program flow chart and ladder diagram.残骛楼諍锩瀨濟溆塹籟。The keyword：PLC ; motor fault ; diagnosis III 目录摘要 ..................................................................................................
