可编程控制器（PC）已被誉为70年代的一场工业革命。自从PC问世以来的短短期间内，给工业控制带来的以前做梦都想不到的非凡变化。使用PC的工业控制系统与传统的用继电器的工业控制系统相比，在操作、控制、效率和精度等各个方面都具有无法比拟的优点。虽然在工业控制系统中所使用的继电器控制设备不会被完全淘汰，但是由于PC的出现已经改变了工业控制设计者的设计思想。

谢谢！

Programmable logic controller (PC) has been known as a 1970s industrial revolution. Since the PC since the advent of the short period of time, to industrial control before the dream can not think all the extraordinary changes. The use of PC systems and industrial control relays with the traditional industrial control systems, in operation, control, efficiency and accuracy of various aspects have incomparable advantages. Although the industrial control systems used in the relay control equipment will not be completely eliminated, but due to the emergence of PC has changed the design of industrial control designers thinking.

The programmable controller (PC) has been honored as the 70s's Industrial Revolution. Has been published in short period since PC, brings before for the industrial control has a dream extraordinary change which could not think. Uses PC the industrial control system and the tradition compares with relay's industrial control system, in the operation, t
