【正文】 chnical knowledge. Can believe, PLC technology will continue to open control system based on the direction of industrial PC transferred, especially the control system. The latter except in flexibility than traditional PLC with a distinct advantage outside, still have other advantages, such as to reduce cost, improve the system from factory layer to enterprise office automation data information flow efficiency, etc. In the 21st century, PLC will have greater development. Technically, the puter technology can morely new achievements used in programmable controller design and manufacturing, there will be faster, storage and larger capacity, intelligent stronger varieties appear。 Look from product patibility, the variety of our products will be more rich, specification more plete, perfect manmachine interface and plete munication equipment can better adapt to all kinds of industrial control occasion demands。 Judging from the development of the work, programmable controller and other industrial control puter working constitute a large control system is programmable controller technology development direction. Along with the development of puter work, the programmable controller as automation control work and international general work will be an important part of the industry and industry, the numerous fields outside play an increasing role. The 1970s, large scale integrated circuit and puter control technology development, and the application of modern control theory, and makes munication power drag system gradually have wide speed range, high steady speed range, high precision and fast steady speed and the dynamic response of quadrant as reversible operation in the technical performance and good performance of speed, can in dc electric drag with parable. In exchange, frequency conversion speed technology have absolute superiority, and its performance of speed and reliability improvement, cutting prices, especially frequency conversion power saving effect is apparent, and easy to realize the process automation, by the industry39。negative switching motor, can undertake highfrequency up to a halt, can undertake electrical braking, can use a frequency converter to several motors for speed control, power supply power factor is big, small, can the power capacity required posed highperformance control system, etc. In many cases, energy is the purpose of using the frequency changer, especially for in the industrial used in gr
