PLC為雙冗余控制設(shè)備。其具有以下優(yōu)點(diǎn)： （1）提供最先進(jìn)的編程特性，易于組態(tài)便于安裝。 （2）CPU具有強(qiáng)大的功能，如內(nèi)裝PID，結(jié)構(gòu)化編程，中斷控制，間接尋址及各種功能模塊能完成復(fù)雜的操作。 （3）高性價(jià)比的雙機(jī)冗余性能。 上位機(jī)界面軟件采用IFIX3.5。系統(tǒng)共配置兩臺(tái)上位機(jī)監(jiān)控系統(tǒng)，一臺(tái)操作員站兼工程師站和一臺(tái)操作員站進(jìn)行控制程序編程，界面軟件組態(tài)和生產(chǎn)過程的監(jiān)控管理，包括：顯示工藝流程，控制各設(shè)備的自動(dòng)化運(yùn)行，顯示歷史趨勢曲線，進(jìn)行報(bào)警管理等。 整個(gè)控制系統(tǒng)組成如圖2所示。 [align=center]
圖2 循泵控制系統(tǒng)[/align] PLC1和PLC2分別為兩個(gè)GE FANUC 90－30系列PLC，通過Genius總線控制器利用Genius總線網(wǎng)連接，以實(shí)現(xiàn)雙機(jī)熱冗余?？紤]到系統(tǒng)成本，在遠(yuǎn)程I/O中，選用了versamax通用擴(kuò)展式I/O結(jié)構(gòu)，利用Genius網(wǎng)絡(luò)接口單元，掛到整個(gè)Genius總線網(wǎng)中，為遠(yuǎn)程控制提供靈活的I/O結(jié)構(gòu)。由于90－30系列PLC支持以太網(wǎng)通訊，在系統(tǒng)中增加一個(gè)8口以太網(wǎng)HUB,PLC和上位機(jī)分別將以太網(wǎng)線接入HUB，實(shí)現(xiàn)上位機(jī)與現(xiàn)場的高速通訊。
系統(tǒng)的實(shí)現(xiàn) 在改造中，通過以下幾點(diǎn)實(shí)現(xiàn)了系統(tǒng)的PLC控制。 3.1 雙機(jī)熱冗余的實(shí)現(xiàn) GE FANUC系列90－30系列的PLC實(shí)現(xiàn)雙機(jī)熱冗余由GE Fanuc系列90-30PLC硬件與熱備軟件max_on構(gòu)成的，90-30 Max-ON系統(tǒng)的冗余硬件部分是由兩套90-30PLC CPU控制器組成，主控制器通過Genius網(wǎng)絡(luò)總線與其備用控制器和I/O系統(tǒng)的通訊實(shí)現(xiàn)其熱備冗余功能，一旦主PLC控制器或通訊出現(xiàn)故障；所有控制功能將平穩(wěn)地切換至備用控制器以確保工藝裝置正常運(yùn)行。系統(tǒng)同時(shí)具有參數(shù)同步化，I/O總線冗余和系統(tǒng)診斷等功能。軟件上90-30 Max-ON提供方便靈活的組態(tài)方式。組態(tài)軟件基于Windows平臺(tái)，采用對(duì)話框方式對(duì)系統(tǒng)進(jìn)行組態(tài)，例如：網(wǎng)絡(luò)結(jié)構(gòu)，同步參數(shù)以及模擬量輸入轉(zhuǎn)換等。完成雙機(jī)配置后,可在系統(tǒng)的程控組態(tài)軟件versapro中引入其配置文件,使兩個(gè)PLC都置于運(yùn)行模式,這樣其冗余特性就揮發(fā)生作用，其主從切換的標(biāo)志位在PLC的存儲(chǔ)器中可以看到。
