對(duì)于小的系統(tǒng)，如80點(diǎn)以內(nèi)的系統(tǒng)，一般不需要擴(kuò)展;當(dāng)系統(tǒng)較大時(shí)，就要擴(kuò)展。不同公司的產(chǎn)品，對(duì)系統(tǒng)總點(diǎn)數(shù)及擴(kuò)展模塊數(shù)量都有限制，當(dāng)擴(kuò)展仍不能滿足需要時(shí)，可采用網(wǎng)絡(luò)結(jié)構(gòu)。同時(shí)，有些廠家產(chǎn)品的個(gè)別指令不支持?jǐn)U展模塊，因此，在進(jìn)行軟件編程時(shí)要注意。當(dāng)采用溫度等模擬模塊時(shí)，各廠家也有一些規(guī)定，請(qǐng)參閱相關(guān)技術(shù)手冊(cè)。

當(dāng)用PLC進(jìn)行網(wǎng)絡(luò)設(shè)計(jì)時(shí)，其難度比PLC單機(jī)控制大得多，首先應(yīng)選用自己比較熟悉的機(jī)型，對(duì)其基本指令和功能指令有較深入的了解，并且指令的執(zhí)行速度和用戶程序存儲(chǔ)容量也應(yīng)仔細(xì)了解。否則不能適應(yīng)實(shí)時(shí)要求，造成系統(tǒng)崩潰。另外對(duì)通信接口，通信協(xié)議、數(shù)據(jù)傳送速度等也要考慮。

后還要向PLC的廠家尋求網(wǎng)絡(luò)設(shè)計(jì)和軟件支持及詳細(xì)技術(shù)資料，至于選用幾層工作站，依照系統(tǒng)大小而定。
