Because the programmable controller (PLC) is specially for one industrial control computer which applies under the industry environment designs, has the antijamming ability to be strong, the reliability is high, the volume slightly, is extremely realizes the integration of machinery ideal control device and so on remarkable merit. Along with science's and technology's development, the programmable control technology's application day by day is also widespread. The engine bed is in the industrial production applies the essential one kind of machine, mainly uses in the machine and each kind of spare part manufacture and the processing.
This article has altogether designed three kind of lathes: Z35 radial drill drilling machine, X62W horizontal type universal milling machines, C560-1 horizontal lathe. This article first elaborated the programmable controller's basic concept, the basic structure and the principle of work, prepare for full for the design. Divided three chapter of distinctions in the later word to introduce three kind of engine bed's electric control principles and the operating process in detail, but also in electric control's foundation to three kind of engine bed's PLC control's hardware wiring, the I/O assignment, the trapezoidal chart, the sentence table has made the detailed elaboration.
Key word: PLC; Engine bed control; Using
