描述

就地總線或現(xiàn)場(chǎng)總線一般由雙絞線組成的數(shù)據(jù)通信網(wǎng)絡(luò)。由于其連接的設(shè)備是與生產(chǎn)過(guò)程直接發(fā)生聯(lián)系的一次元件或控制設(shè)備，所以工作環(huán)境惡劣，故障率高，容易受到檢修人員的誤動(dòng)而影響生產(chǎn)過(guò)程。另外，總線本身也會(huì)因種種原因造成通信故障。防止此類故障的有效方法是，首先要將就地總線與就地設(shè)備的聯(lián)接點(diǎn)進(jìn)行妥善處理，拆裝設(shè)備時(shí)，不得影響總線的正常運(yùn)行，總線分支應(yīng)安裝在不易碰觸的地方。同時(shí)，就在總線最好是采用雙路冗余配置，以提高通信的可靠性。
