Industrial Automation consists of three levels, from bottom to top is the basis for automation, process automation and management automation, its core is the basis and process automation. Traditional automation systems, basic automation section basically monopolized PLC and DCS, process automation and management automation part is mainly imported from a variety of process computer or minicomputer, the price of many of its hardware, system software and application software to make high business prohibitive. Since the 1990s, due to the PC-based industrial computer (referred to as industrial PC) the development of an industrial PC, I / O devices, monitoring devices, the control network consisting of PC-based automation system has been rapidly growing popularity, becoming achieve an important way to low-cost industrial automation. Chongqing Iron and Steel Company of such big companies, almost all large-scale furnace, also demolished original DCS or single-loop digital regulator, and use PC to compose industrial control systems, and the use of fuzzy control algorithm, to obtain good results. Market due to PC-based controllers are proven to be the same as the PLC *, and accepted by the operating and maintenance personnel, so that one by one manufacturer, at least in part the production is using PC control program. PC-based control system is easy to install and use, there are advanced diagnostic capabilities, provides a more flexible option for system integrators, in the long run, PC control system maintenance costs low. Since the programmable logic controller (PLC) controlled by the biggest threat to PC, so PC application PLC suppliers feel very uneasy. In fact, the programmable logic controller (PLC) also added to the PC Control "wave". Industrial PC in China has been very rapid development. From a global perspective, the industrial PC consists mainly of two types: IPC IPC IPC and CompactPCI and their texturing machine, such as industrial machines and other AT96 bus. Due to the high basic and process automation for industrial PC's operating stability, hot-swappable and redundant configuration requirements, the existing IPC can not fully meet the requirements, will gradually withdraw from the field, will be replaced by CompactPCI-based IPC and the IPC will occupy management automation layer. The state established in 2001 "to industry control of computer-based control system of open industrialization" major projects in industrial automation, the goal is the development of PC-based control system with independent intellectual property rights, and in 3 (5 years, occupying 30% ( 50% of the domestic market, and to achieve industrialization. A few years ago, when the "soft PLC" appears, the industry had thought industrial PC will replace the PLC. However, to date there is no substitute Industrial PC and PLC, there are two main reasons : One reason is the system integration; the other is the reason WindowsNT operating system software for a successful PC-based control system must have two things: First of all to be done by the software on a single platform; the second is to provide the required everything can be predicted that the industrial PC and PLC will mainly compete in the high-end applications, the data is complex and highly integrated devices, industrial PC can not compete with low-cost micro PLC, which is the fastest growing part of the PLC market From the development trend, the control system of the future is likely to exist between the Industrial PC and PLC, the integration of these signs have emerged.
