它把現(xiàn)場(chǎng)控制器和人機(jī)界面連成一個(gè)系統(tǒng)。為了確保通訊可靠,DCS生產(chǎn)廠家無(wú)論是電纜,還是通訊接口,都作成冗余的,一條網(wǎng)絡(luò)發(fā)生故障,另一條備用網(wǎng)絡(luò)立即投入運(yùn)行。連在DCS通訊網(wǎng)絡(luò)上的部件稱為結(jié)點(diǎn)(節(jié)點(diǎn))。在地理位置上,結(jié)點(diǎn)可以分散配置,各結(jié)點(diǎn)的距離各DCS系統(tǒng)不同,有的可達(dá)幾百米。DCS網(wǎng)絡(luò)的傳輸速率在幾百K至一百兆之間,網(wǎng)絡(luò)的總長(zhǎng)度可達(dá)幾公里,zui短也有幾百米,網(wǎng)絡(luò)不夠長(zhǎng)時(shí)需加中繼器。
我公司采用的Cnet是采用存儲(chǔ)轉(zhuǎn)發(fā)式協(xié)議的擁有19個(gè)節(jié)點(diǎn)的冗余的環(huán)型網(wǎng)絡(luò)。
