FCS正是順應(yīng)以上潮流而誕生，它用現(xiàn)場(chǎng)總線這一開(kāi)放的，具有可互操作的網(wǎng)絡(luò)將現(xiàn)場(chǎng)各控制器及儀表設(shè)備互連，構(gòu)成現(xiàn)場(chǎng)總線控制系統(tǒng)，同時(shí)控制功能下放到現(xiàn)場(chǎng)，降低了安裝成本和維護(hù)費(fèi)用。因此，F(xiàn)CS實(shí)質(zhì)是一種開(kāi)放的、具可互操作性的、分散的分布式控制系統(tǒng)，有望成為21世紀(jì)控制系統(tǒng)的主流產(chǎn)品。

現(xiàn)場(chǎng)總線及現(xiàn)場(chǎng)總線控制系統(tǒng)

現(xiàn)場(chǎng)總線的概念

現(xiàn)場(chǎng)總線是將自動(dòng)化底層的現(xiàn)場(chǎng)控制器和現(xiàn)場(chǎng)智能儀表設(shè)備互連的實(shí)時(shí)控制通訊網(wǎng)絡(luò)，遵循ISO的OSI開(kāi)放系統(tǒng)互連參考模型的全部或部分通訊協(xié)議。FCS則是用開(kāi)放的現(xiàn)場(chǎng)總線控制通訊網(wǎng)絡(luò)將自動(dòng)化底層的現(xiàn)場(chǎng)控制器和現(xiàn)場(chǎng)智能儀表設(shè)備互連的實(shí)時(shí)網(wǎng)絡(luò)控制系統(tǒng)

現(xiàn)場(chǎng)總線與局域網(wǎng)的區(qū)別

按功能比較，現(xiàn)場(chǎng)總線連接自動(dòng)化底層的現(xiàn)場(chǎng)控制器和現(xiàn)場(chǎng)智能儀表設(shè)備，網(wǎng)線上傳輸?shù)氖切∨繑?shù)據(jù)信息，如檢測(cè)信息、狀態(tài)信息、控制信息等，傳輸速率低，但實(shí)時(shí)性高。簡(jiǎn)而言之，現(xiàn)場(chǎng)總線是一種實(shí)時(shí)控制網(wǎng)絡(luò)。局域網(wǎng)用于連接局域區(qū)域的各臺(tái)計(jì)算機(jī)，網(wǎng)線上傳輸?shù)氖谴笈康臄?shù)字信息，如文本、聲音、圖像等，傳輸速率高，但不要求實(shí)時(shí)性。從這個(gè)意義而言，局域網(wǎng)是一種高速信息網(wǎng)絡(luò)。

按實(shí)現(xiàn)方式比較現(xiàn)場(chǎng)總線可采用各種通訊介質(zhì)，如雙絞線、電力線、光纖、無(wú)線、紅外線等，實(shí)現(xiàn)成本低。局域網(wǎng)需要電纜，如同軸電纜、光纖等，實(shí)現(xiàn)成本高。

3503EN module
FCS is born in line with the above trend, it uses the fieldbus this open, with interoperable network to interconnect the field controller and instrument equipment, constitute the fieldbus control system, while the control function is placed on the site, reducing the installation cost and maintenance costs. Therefore, the essence of FCS is an open, interoperable and decentralized distributed control system, which is expected to become the mainstream product of control systems in the 21st century.
Fieldbus and fieldbus control system
The concept of fieldbus
Fieldbus is a real-time control communication network that interconnects the automation underlying field controller and field intelligent instrumentation devices, following all or part of the communication protocol of ISO’s OSI Open Systems Interconnection reference model. FCS is a real-time network control system that uses an open fieldbus control communication network to connect the automation base field controller and field intelligent instrument equipment
The difference between fieldbus and LAN
According to the function comparison, the fieldbus connects the field controller and the field intelligent instrument equipment at the bottom of the automation, and the data information transmitted on the network cable is small batches of data information, such as detection information, status information, control information, etc., with low transmission rate but high real-time performance. In short, fieldbus is a real-time control network. LAN is used to connect each computer in the local area, the network cable is transmitted on a large number of digital information, such as text, sound, images, etc., the transmission rate is high, but it does not require real-time. In this sense, local area network is a kind of high-speed information network.
According to the implementation method, fieldbus can use various communication media, such as twisted pair, power line, optical fiber, wireless, infrared, etc., to achieve low cost. Local area networks require cables, such as coaxial cables, optical fibers, etc., and the implementation cost is high.
