西門子 S7-300PLC選型及設(shè)計(jì)要點(diǎn)詳細(xì)介紹
S7-300PLC選型及設(shè)計(jì)要點(diǎn) 一 、選型要點(diǎn)S7-300PLC的選型原則是據(jù)生產(chǎn)工藝所需的功能和容量進(jìn)行選型,并考慮維護(hù)的方
便性、備件的通用性,以及是否易于擴(kuò)展和有無特殊功能等要求。選型時(shí)具體注意以下幾方面:(1)有關(guān)參數(shù)確定。一是輸入/
輸出點(diǎn)數(shù)(I/O點(diǎn)數(shù))確定。這是確定PLC規(guī)模的一個(gè)重要依據(jù),一定要根據(jù)實(shí)際情況留出適當(dāng)余量和擴(kuò)展余地。二是PLC存儲(chǔ)容
量確定。注意當(dāng)系統(tǒng)有模擬量信號(hào)存在或要進(jìn)行大量數(shù)據(jù)處理時(shí),其存儲(chǔ)容量應(yīng)選大一些。
SIMATIC S7-300是模塊化的微型PLC系統(tǒng),可滿足中、低端的性能要求。模塊化、無風(fēng)扇設(shè)計(jì)、易于實(shí)現(xiàn)分布式結(jié)構(gòu)以及方便
的操作,使得 SIMATIC S7-300 成為中、低端應(yīng)用中各種不同任務(wù)的經(jīng)濟(jì)、用戶友好的解決方案。SIMATICS7-300的應(yīng)用領(lǐng)域
包括:特殊機(jī)械,紡織機(jī)械,包裝機(jī)械,一般機(jī)械設(shè)備制造,控制器制造,機(jī)床制造,安裝系統(tǒng),電氣與電子工業(yè)及相關(guān)產(chǎn)業(yè)。
