ENK32 現(xiàn)場總線控制系統(tǒng)利用現(xiàn)場總線作為工業(yè)控制系統(tǒng)的骨干網(wǎng)絡

ENK32現(xiàn)場總線控制系統(tǒng)（Fieldbus Control System，F(xiàn)CS）是集散控制系統(tǒng)（Distributed Control System，DCS）的更新?lián)Q代產(chǎn)品，并且已經(jīng)成為工業(yè)生產(chǎn)過程自動化領域中一個新的熱點?，F(xiàn)場總線技術(shù)是20世紀90年代興起的一種先進的工業(yè)控制技術(shù)，它將現(xiàn)今網(wǎng)絡通信與管理的觀念引入工業(yè)控制領域。從本質(zhì)上說，它是一種數(shù)字通信協(xié)議，是連按智能現(xiàn)場設備和自動化系統(tǒng)的數(shù)字式、全分散、雙向傳輸、多分支結(jié)構(gòu)的通信網(wǎng)絡。它是控制技術(shù)、儀表工業(yè)技術(shù)和計算機網(wǎng)絡技術(shù)三者的結(jié)合，具有現(xiàn)場通信網(wǎng)絡、現(xiàn)場設備互連、互操作性、分散的功能塊、通信線供電和開放式互連網(wǎng)絡等技術(shù)特點。這些特點不僅保證了它完全可以適應工業(yè)界對數(shù)字通信和自動控制的需求，而且使它與Internet 互連構(gòu)成不同層次的復雜網(wǎng)絡成為可能，代表了今后工業(yè)控制體系結(jié)構(gòu)發(fā)展的一種方向。

現(xiàn)場總線控制系統(tǒng)利用現(xiàn)場總線作為工業(yè)控制系統(tǒng)的骨干網(wǎng)絡，ENK32以滿足工業(yè)現(xiàn)場中，控制系統(tǒng)、執(zhí)行機構(gòu)和測量設備之間能夠?qū)崿F(xiàn)多節(jié)點數(shù)字通信的需求，具有可拓展性強、組網(wǎng)靈活的特點。此外，該系統(tǒng)還具有分散性、開放性和低成本等優(yōu)點。在分散性方面，控制功能分散到現(xiàn)場設備，使系統(tǒng)具有更高的靈活性和可靠性，分散的控制系統(tǒng)使根據(jù)控制需求的變化而重組和擴建原有的控制系統(tǒng)變得更加方便，對于系統(tǒng)的維護工作也更加容易。在開放性方面，通信網(wǎng)絡采用公開化、標準化的解決方案，從而使用戶在選擇不同廠家的工控產(chǎn)品時更加靈活，組網(wǎng)更加方便。在低成本方面，分布式結(jié)構(gòu)采用數(shù)字信號傳輸方式替代了集散控制系統(tǒng)中的模擬信號傳輸方式，省去了許多數(shù)/模、模/數(shù)轉(zhuǎn)換裝置；控制功能的分散下放，簡化了系統(tǒng)結(jié)構(gòu)、節(jié)約了硬件設備和連接電纜，縮短了開發(fā)周期，減少了維護費用。

集散控制系統(tǒng)（DCS）也稱為分布式控制系統(tǒng)，它把控制技術(shù)、計算機技術(shù)、圖像顯示技術(shù)以及通信技術(shù)結(jié)合起來,實現(xiàn)對生產(chǎn)過程的監(jiān)視、控制和管理。它既打破了常規(guī)控制儀表功能的局限,又較好的解決了早期計算機系統(tǒng)對于信息、管理和控制作用過于集中帶來的危險性。它主要用于大規(guī)模的連續(xù)過程控制系統(tǒng)中, 如石化、電力等。

綜上所述，ENK32現(xiàn)場總線控制系統(tǒng)是一種具有高度分散性、開放性和低成本的控制系統(tǒng)，它利用現(xiàn)場總線作為通信骨干網(wǎng)絡，實現(xiàn)了控制系統(tǒng)、執(zhí)行機構(gòu)和測量設備之間的多節(jié)點數(shù)字通信。相比傳統(tǒng)的集散控制系統(tǒng)，現(xiàn)場總線控制系統(tǒng)具有更高的靈活性和可靠性，并能降低整個工程生命周期的綜合成本。

ENK32 Fieldbus Control System (FCS) is the replacement of Distributed Control System (DCS), and has become a new hot spot in the field of industrial process automation. Fieldbus technology is an advanced industrial control technology that arose in the 1990s. It introduces the concept of network communication and management into the field of industrial control. In essence, it is a digital communication protocol, is connected to intelligent field equipment and automation system of digital, fully decentralized, two-way transmission, multi-branch structure of the communication network. It is a combination of control technology, instrument industry technology and computer network technology. It has the technical characteristics of field communication network, field equipment interconnection, interoperability, decentralized functional blocks, communication line power supply and open interconnection network. These characteristics not only ensure that it can fully adapt to the needs of the industry for digital communication and automatic control, but also make it possible to interconnect with the Internet to form complex networks at different levels, representing a direction for the development of industrial control architecture in the future.

The fieldbus control system uses the fieldbus as the backbone network of the industrial control system, ENK32 to meet the needs of multi-node digital communication between the control system, the actuator and the measuring equipment in the industrial field, and has the characteristics of strong scalability and flexible networking. In addition, the system has the advantages of decentralization, openness and low cost. In terms of decentralization, the control function is dispersed to the field equipment, so that the system has higher flexibility and reliability, the decentralized control system makes it more convenient to reorganize and expand the original control system according to the change of control needs, and the maintenance of the system is also easier. In terms of openness, the communication network adopts open and standardized solutions, so that users are more flexible when choosing industrial control products from different manufacturers, and the networking is more convenient. In the aspect of low cost, the distributed structure adopts the digital signal transmission mode to replace the analog signal transmission mode in the distributed control system, and saves many digital/mode and analog/digital conversion devices. Decentralized control functions simplify the system structure, save hardware equipment and connecting cables, shorten the development cycle, and reduce maintenance costs.

Distributed control system (DCS) is also known as distributed control system, which combines control technology, computer technology, image display technology and communication technology to realize the monitoring, control and management of the production process. It not only breaks the limitation of the conventional control instrument function, but also better solves the danger brought by the early computer system for the information, management and control function too centralized. It is mainly used in large-scale continuous process control systems, such as petrochemical, electric power and so on.

In summary, the ENK32 fieldbus control system is a highly decentralized, open and low-cost control system, which uses the fieldbus as the communication backbone network to realize the multi-node digital communication between the control system, the actuator and the measuring equipment. Compared with the traditional distributed control system, the fieldbus control system has higher flexibility and reliability, and can reduce the comprehensive cost of the whole engineering life cycle.
