石油化工生產(chǎn)中plc常常用于大機(jī)組的聯(lián)鎖與操控。對(duì)于機(jī)組的振蕩、位移等參數(shù)，點(diǎn)數(shù)較少時(shí)，能夠選用變送器、傳感器變換成4-20ma信號(hào)送入plc，完成聯(lián)鎖操控，但對(duì)鍵相、差脹等特別丈量參數(shù)或振蕩、位移等丈量參數(shù)點(diǎn)數(shù)較多時(shí)，信號(hào)變換的難度大、成本高，運(yùn)用傳統(tǒng)的框架式機(jī)械維護(hù)體系反而會(huì)經(jīng)濟(jì)、有用。美國(guó)bently公司3500體系是傳統(tǒng)的框架式機(jī)械維護(hù)體系之一，它能夠運(yùn)行于各種冗余等級(jí)，包括雙電源供電和更高請(qǐng)求下的三重模塊冗余(tmr)監(jiān)測(cè)器組態(tài)。每個(gè)i/o卡能夠?qū)?4-6個(gè)點(diǎn)的信號(hào)進(jìn)行變換處理，并經(jīng)過(guò)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(shè)備的壓縮機(jī)聯(lián)鎖、操控中，選用德國(guó)西門(mén)子公司的s7-400h體系完成總的聯(lián)鎖和進(jìn)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(hào)和報(bào)警、聯(lián)鎖信號(hào)以通訊方法傳輸?shù)絪7-400h。本文以2＃丁二烯壓縮機(jī)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(jìn)程。
