石油化工生產(chǎn)中plc常常用于大機組的聯(lián)鎖與操控。對于機組的振蕩、位移等參數(shù)，點數(shù)較少時，能夠選用變送器、傳感器變換成4-20ma信號送入plc，完成聯(lián)鎖操控，但對鍵相、差脹等特別丈量參數(shù)或振蕩、位移等丈量參數(shù)點數(shù)較多時，信號變換的難度大、成本高，運用傳統(tǒng)的框架式機械維護體系反而會經(jīng)濟、有用。美國bently公司3500體系是傳統(tǒng)的框架式機械維護體系之一，它能夠運行于各種冗余等級，包括雙電源供電和更高請求下的三重模塊冗余(tmr)監(jiān)測器組態(tài)。每個i/o卡能夠?qū)?4-6個點的信號進行變換處理，并經(jīng)過編程的辦法完成聯(lián)鎖邏輯。茂名乙烯廠在2006年7月建成投產(chǎn)的2＃丁二烯設備的壓縮機聯(lián)鎖、操控中，選用德國西門子公司的s7-400h體系完成總的聯(lián)鎖和進程操控，外殼振蕩、軸瓦溫度的聯(lián)鎖主要在bently3500中完成。為了完成數(shù)據(jù)同享和聯(lián)鎖冗余，需要將bently3500中的模擬信號和報警、聯(lián)鎖信號以通訊方法傳輸?shù)絪7-400h。本文以2＃丁二烯壓縮機操控體系為例，描繪了simatic s7-400h與bently 3500之間modbus rtu協(xié)議通訊完成的進程。
