With the continuous development of industrial level, mechanical equipment has been gradually from manual to automatic control, the device itself also developed into a plex of electromechanical integration. PLC programmable controller is a microprocessor as the core, integrated puter technology, automation technology and munication technology, developed a kind of new industrial automatic control device. In 1969, the digital equipment corporation DEC, successfully developed the first PLC model for PDP 14. In a short span of more than 40 years, PLC has experienced five times. At present, the programmable controller has bee the most important and most used in industrial automation control equipment, the three pillars of industrial production automation (PLC, robotics, puter aided design and manufacturing) of the first. Its depth and width of the broad bee to measure a nation39。 Gave birth to a variety of special function unit, and produces all kinds of manmachine interface unit, munication unit, the application of PLC industrial control equipment supporting more easily。 PLC to open development。 Soft PLC. PLC programming language tends to be standardized. Its application field is constantly expanding, and extends to the process control, batch processing, motor and drive control, wireless remote control to realize integrated automation for the factory. IPC in recent years, industrial puter technology and field bus technology has developed rapidly, from the market part of the PLC, PLC appears the trend of gradual growth rate, but its status in ind
