調(diào)換鋰電池的步驟為：
■在拆裝前，應(yīng)先讓PLC通電15秒以上（這樣可使作為存儲(chǔ)器備用電源的電容器充電，在鋰電池?cái)嚅_(kāi)后，該電容可對(duì)PLC做短暫供電，以保護(hù)RAM 中的信息不丟失）；
■斷開(kāi)PLC的交流電源；
■打開(kāi)基本單元的電池蓋板；
■取下舊電池，裝上新電池；
■蓋上電池蓋板。
注意更換電池時(shí)間要盡量短，一般不允許超過(guò)3分鐘。如果時(shí)間過(guò)長(zhǎng)，RAM中的程序?qū)⑾А?/span>
此外,應(yīng)注意更換保險(xiǎn)絲時(shí)要采用型號(hào)的產(chǎn)品。
I/O模塊的更換
若需替換一個(gè)模塊，用戶應(yīng)確認(rèn)被安裝的模塊是同類型。有些I/O系統(tǒng)允許帶電更換模塊，而有些則需切斷電源。若替換后可解決問(wèn)題，但在一相對(duì)較短時(shí)間后又發(fā)生故障，那么用戶應(yīng)檢查能產(chǎn)生電壓的感性負(fù)載，也許需要從外部抑制其電流尖峰。如果保險(xiǎn)絲在更換后易被燒斷，則有可能是模塊的輸出電流超限，或輸出設(shè)備被短路。
PLC的故障診斷是一個(gè)十分重要的問(wèn)題，是保證PLC控制系統(tǒng)正常、可靠運(yùn)行的關(guān)鍵。本文對(duì)常用的故障診斷方法進(jìn)行了探討。在實(shí)際工作過(guò)程中，應(yīng)充分考慮到對(duì)PLC的各種不利因素，定期進(jìn)行檢查和日常維護(hù)，以保證PLC控制系統(tǒng)安全、可靠地運(yùn)行。
