The development direction of PLC - From the science and technology

PLC has been for many years of development history, along with the development of semiconductor technology, computer technology and communication technology, there have been very big changes in the area of industrial control, PLC, too, the widening of the application of PLC, the PLC technology and its product structure have been improved, the increasingly powerful, cost performance is higher and higher. （ 1) PLC miniaturization development function of PLC is more and more rich, and the volume is smaller and smaller. Early PLC is no longer the only switch logic operations and products, but with more and more strong analog processing ability, and the other in the past only on the computer with advanced processing capabilities, such as floating-point arithmetic, PID control, temperature control, precise positioning, stepper drives, statistics report, etc. Such as regard the coolmay PLC all-in-one - design research and development of science and technology CX2N - 嗯- - - - - - 32 m high width = 125 * 90 * 36 PLC machine out of the volume is very small, but it does have a highly integrated, support for multiple counting high-speed, high-speed pulse characteristics and processing power is very strong. （ 2) PLC network technical development of PLC network control is the control system and PLC technology development trend. Networking communication between PLC and PLC has been widely used. At present, the PLC manufacturers ( Gu beauty science and technology, for example) Are developing their dedicated communication module and PLC network communication software to enhance capacity. Each PLC manufacturers also general communication standards specified in the negotiations, to form larger network system. （ 3) To modular, intelligent development to meet the demand of various industrial automation control system, PLC manufacturers have developed many new modules, such as intelligent I/O module, temperature control module and dedicated a special intelligent module for PLC external fault detection, etc. , development and application of these modules not only enhances the functionality, expanded the application field of PLC, also improve the reliability of the system. Coolmay CM series amplifier module will use PLC is small power output signal through the optical coupling isolation into a thick high power output control signals, and then drive control motor, solenoid valve, such as high power load, at the same time protect the function of PLC. （ 4) PLC to develop in the direction of easy operation. PLC is one of the difficulty of the promotion by complex programming enables users, and all different vendors PLC programming language are also different, difficult to hinder the further development of PLC. The PLC development inevitably in the operation simplifies the complicated task of programming, in this regard the technology as the forerunner, only need to input some parameters in the dialog, you can automatically generate the user program, including interrupt program, greatly facilitate the use of the user. （ 5) Programming languages and programming tools the diversification and standardization of coexist, complementary and development of a variety of programming language is a kind of trend of PLC software progress. PLC manufacturer in making hardware and programming tools and upgrading frequently, rich variety, function to improve at the same time, rising to the MAP ( Manufacturing automation protocol) Together, make the PLC basic components, including input and output module, communication protocols and programming languages and programming tools of technology and standardization. Because we have been focused on design of PLC industrial automation products research and development, we sincerely provide customers with more reliable and more affordable embedded industrial control products. The future development direction of PLC, we regard the United States must use the most sincere heart to contribute our strength.
