Abstract: For many years, the programmable controller (has hereafter referred to as PLC) to produce from it to the present, has realized the wiring logic to the stored logic leap; Its function from weak ones to strong ones, realized logic to control the numerical control the progress; Its application domain from infancy to maturity, realized the monomer equipment to control the competent movement control, the process control and the collection and distribution control simply and so on each kind of duty spanning. Today PLC in the processing simulation quantity, the digital operation, the man-machine connection and network various aspects ability all largely enhanced, becomes the industry control domain the mainstream control device, is playing the more and more major role in all the various trades and occupations.
Key words: Programmable controller; Monomer equipment simple control;
