Industrial Control and PLC Industrial control automation technology is an application of control theory, instrumentation, computers and other information technology, industrial production processes for detection, control, optimization, scheduling, management and decision-making, to increase production, improve quality, reduce consumption, to ensure the safety The purpose of the integrated technology, including industrial automation software, hardware and systems in three. Industrial control automation technology as the 20th century, the area of modern manufacturing technology, one of the most important, the main solution to the issue of productivity and consistency. Although the automation system itself does not directly create effective, but its production process to enhance the role of obvious. Chinas industrial automation control the path of development are the introduction of complete sets of equipment to carry out digestion and absorption at the same time, and then the development and application of a second. Chinas industrial control automation technology, industries and applications have a lot of development, Chinas industrial computer systems industry has been formed.At present, industrial control automation technology is the intelligent, network-based and integrated direction. To micro-PLC, network, PC and open development A long period of time, PLC in industrial control automation has always been the main battlefield of the field for a wide range of automation control equipment to provide highly reliable control, DCS and industrial PC with a trend of the three. At the same time, PLC also suffer from the impact of other technology products, especially industrial impact of PC. Currently, the PLC manufacturers around the world about 200, producing over 300 kinds of products. PLC is still abroad, the domestic market products, such as Siemens, Modicon, AB, OMRON, Mitsubishi, GE products. After years of development, the domestic manufacturers PLC about 30, but there is no large-scale production capacity and brand-name products, it can be said PLC has not yet formed in our manufacturing industry.PLC application in China is very active, the application of a wide range of industries. Experts estimate that in 2000 the domestic market sales of PLC for 15 (20 million units (of which about 90% of imports), about 25 (35 billion yuan, an annual growth rate of about 12%. Estimated that in 2005 the demand for National PLC will reach about 250,000 units, about 35 (45 billion yuan. PLC market is also reflected in the state of the worlds manufacturing sector, fell sharply after 2000. However, in accordance with the Automation Research Corp forecasts, despite the global economic downturn, PLC market will recover, it is estimated that the global PLC market in 2000 for 7.6 billion U.S. dollars, by the end of 2005 to 7.6 billion U.S. dollars will return and continue to increase slightly. Miniaturization, networking, PC-based PLC and openness are the main directions of future development. PLC-based automation in the early, PLC bulky and expensive. However, in recent years, micro-PLC (less than 32 I / O) has occurred, the price only a few hundred euros.With the soft PLC (Soft PLC) control configuration software to further improve and develop, is equipped with soft-PLC configuration software and PC-based control of the market share will gradually increase. At present, the field of process control, one of the biggest trends is the expansion of Ethernet technology, PLC is no exception. PLC is now a growing number of suppliers providing Ethernet interface. It is believed that, PLC will continue to open the direction of the transfer of control systems, especially PC-based industrial control systems. (Source: Industrial Network) Small size, diversification, PC and open the future development direction of DCS. DCS is currently a small market share has been gradually and PLC, industrial PC, FCS sharing. First of all, the future may be small-scale DCS system with the integration of these three, and soft DCS technology will first be developed small-scale DCS.PC-based control will be more widely used in small and medium-sized process control, the DCS will also be vendors have been offering PC-based small-scale industrial DCS systems. Open to the DCS system at the same time two-way upward and downward extension of the production process from field data across the enterprise within the free flow of information technology and control technology, seamlessly integrated to control the direction of the development of monitoring and control. Information technology industry is defined as industrial production, management, business process, through the information infrastructure, in an integrated platform of information acquisition, information transmission, information processing and comprehensive utilization of such information.To develop as a result of industrial automation is to speed up the transformation of traditional industries to upgrade and improve the overall quality of enterprises, improve the countrys overall national strength, adjusting the industrial structure, to invigorate large and medium-sized enterprises, the rapid and effective ways and means, the state will continue through the implementation of a series of high-tech industry of industrial process automation of special, using information technology to stimulate industrialization and the promotion of industrial automation technology to further develop and strengthen technological innovation, to achieve industrialization and economic development to solve the underlying problem, to further improve the overall quality of the national economy and overall national strength, the development by leaps and bounds.
