描述
S5PLC具有自診斷能力,發(fā)生模塊功能錯誤時往往能報警并按預(yù)先程序作出反應(yīng),通過故障指示燈就可判斷。當(dāng)電源正常,各指示燈也指示正常,特別是輸入信號正常,但系統(tǒng)功能不正常(輸出無或亂)時,本著先易后難、先軟后硬的檢修原則首先檢查用戶程序是否出現(xiàn)問題。S5的用戶程序儲存在PLC的RAM中,是掉電易失性的,當(dāng)后備電池故障系統(tǒng)電源發(fā)生閃失時,程序丟失或紊亂的可能性就很大,當(dāng)然強烈的電磁干擾也會引起程序出錯。有EPROM存儲卡及插槽的PLC恢復(fù)程序就相當(dāng)簡單,將EPROM卡上的程序拷回PLC后一般都能解決問題;沒有EPROM子卡的用戶就要利用PG的聯(lián)機功能將正確的程序發(fā)送到PLC上。需要特別說明的是,有時簡單的程序覆蓋不能解決問題,這時在重新拷貝程序前總清一下RAM中的用戶程序是相當(dāng)必要的。通過將PLC上的“RUN”“ST”開關(guān)按RUN—ST—RUN—ST—RUN的順序撥打一遍或在PG上執(zhí)行“Object—Blocks—delet—inPLC—allblocks—overall—Reset”功能就完成了RAM中程序的總清。另外,保存在EPROM中的程序并不是萬無一失的,過分相信EPROM上的程序有時會給檢修帶來困惑。所以經(jīng)常性的檢查核對EPROM中的程序,特別是PG中的備份程序就顯的尤為重要。
