Abstract With the rapid development of the microelectric technique and computer technology, PLC (namely programmable controller ) gets widely application very in the industry controlled field. PLC is one kind on the basis of technology of digital computer, electronic control device designed to use under the environment of industry specially, adopt it by memory that can programme, it is last user order not to used for,through figure or introductions of simulation /export, finish such functions confirmed as a series of logic , order , timing , counting , operation ,etc., to control all kinds of integrated equipment of electromechanics and production process. The introduction to this text utilizes the control systems of a five - storeyed lift where the programmable controller is written, running situation of the inspection lift PLC control system. Practice has proved PLC can is it favorable to design , measuring , PLC of control system to combine all over between controller and MCGS configuration software Cheng, have good using value .
