Programmable controller is the computer technology and automation technology suitable for industrial environments combining a new universal automatic control device and developed as a conventional relay replacement product emerged. As microelectronics and the rapid development of computer technology industrial products company, PLC more of a function of the computer, not only to implement logic control, but also with the data processing, communications, networking and other functions. Because it can be changed through software control process, and has a small, assembled, easy maintenance, simple programming, high reliability, strong anti-interference ability and other characteristics, has been widely used in industrial control, greatly promoted the mechatronics process. Distributed Control System (DCS Distributed Control System) is a high performance, high quality, low cost, flexible configuration of distributed control system products, can pose a variety of independent control systems, distributed control system DCS, supervisory control and data acquisition system (SCADA), to meet the needs of various industrial process control and information management. The modular system design, rational configuration of hardware and software features and easy to expand capacity, to a wide variety of large, medium and small-scale power station renovation decentralized control, power plant automation systems and steel, petrochemicals, paper, cement, etc. industrial process control. China has the world's largest industrial automation control system devices market, technological transformation of traditional industries, factory automation, enterprise information requires a lot of industrial automation systems, market prospects. Industrial control automation technology is developing intelligent, networked and integrated direction. Based on industrial automation and control better prospects for development in 2015 manufacturing industrial automation control system devices industry market size will more than 350 billion yuan. With the growing industrial automatic control system equipment manufacturing industry competition, large equipment manufacturing industrial automation systems integration and capital operation, mergers and acquisitions have become more frequent supplier of industrial products, excellent domestic industrial automatic control system device manufacturers increasingly focus on industry market research, especially for the industrial development environment and the buyers of the products studied. Press control principle of different automatic control system is divided into open-loop control system and closed-loop control system.
