PLC programmable controller: PLC English name Programmable logic Controller, Chinese called the programmable logic controller, it is defined as: a digital computing operation of electronic systems, designed for use in industrial environments and design. It uses a programmable memory Industrial Products, for its internal storage procedures industrial products, the implementation of logical, sequential control, timing, user-oriented instruction counting and arithmetic operations such industrial product profiles, and through digital or analog input / output control of all types of machinery or production processes. Programmable control system (Programmable Logic Controller) is a digital computing operation of electronic systems designed for applications in industrial environments designed. It uses a programmable memory, in its internal memory to perform logical, sequential control, timing, counting and arithmetic operations such as operating instructions, to control various types of machinery or production through digital or analog input and output process. Science and technology are primary productive forces, science and technology is an important development instrument "Tools." Mr. Wang Daheng renowned scientists pointed out that "the transformation of the world machine tools, instruments are tools to understand the world." Instrument industrial production, "multiplier" of industrial products manufacturers address, is scientific research, "vanguard" and "combat" military is a modern social activities "materialization judge." Needless to say, the instrument in the modern era to promote the development of science and technology and the national economy has a very important position. 1. The instrument is an important prerequisite and fundamental guarantee of scientific and technological development. Any time a big leap in the history of human development are based on innovative tools and a huge fundamental change driven as "tool" of scientific instruments of development and innovation is often an important element of the birth of science and technology innovation. 2. The instrument is an important guarantee of economic development and national security. Instrument is to protect economic development, national security indispensable basic conditions. First, the famous scientist Qian Xuesen said: "The key technology of the new technological revolution in information technology computer technology, communication technology by the three parts IT measurement technology, measurement technology is the key and foundation..." 3. The instrument is to promote an important force in building a harmonious society. Currently, the global resource depletion, environmental pollution and other issues become the bottleneck of social health development; food safety issues, public emergencies, disease diagnosis, explosive hazardous chemicals and other people's lives to the serious impact of these major problem-solving are inseparable advanced detection technology and tools.
