西門子模塊CPU319-3PN/DP燈全亮修復，西門子處理器維修，西門子S7-300維修銷售

西門(men)子s7-400及PLC300所有燈全亮 不運行(xing)故(gu)(gu)障(zhang)(zhang)處理(li)，這個(ge)故(gu)(gu)障(zhang)(zhang)算是(shi)cpu出(chu)現比(bi)較高(gao)的故(gu)(gu)障(zhang)(zhang)，這個(ge)故(gu)(gu)障(zhang)(zhang)術語稱作不啟(qi)動(dong)(dong)，意思是(shi)說西門(men)子plc類似(si)一(yi)個(ge)電腦(nao)CPU或者內存或者周圍器件出(chu)現故(gu)(gu)障(zhang)(zhang)，啟(qi)動(dong)(dong)過程卡住了，燈全亮，沒法正常啟(qi)動(dong)(dong)。這個(ge)故(gu)(gu)障(zhang)(zhang)顯現99%以上是(shi)硬(ying)件問題，或者供電，或者存儲芯片，亦或者復位時(shi)鐘等等故(gu)(gu)障(zhang)(zhang)導致，此時(shi)這個(ge)cpu除了報(bao)廢就(jiu)是(shi)選擇維修(xiu)了。

首先，檢查接(jie)(jie)線(xian)：電(dian)(dian)源(yuan)(yuan)線(xian)是(shi)不(bu)是(shi)已經(jing)連接(jie)(jie)到供電(dian)(dian)電(dian)(dian)源(yuan)(yuan)端(duan)子(zi)（PLC一般有(you)多組電(dian)(dian)源(yuan)(yuan)端(duan)子(zi)，分(fen)為三種類似：模(mo)塊(kuai)供電(dian)(dian)電(dian)(dian)源(yuan)(yuan)、輸(shu)入傳感器電(dian)(dian)源(yuan)(yuan)、輸(shu)出驅動電(dian)(dian)源(yuan)(yuan)）；

其次，檢查(cha)電(dian)源(yuan)：外部供(gong)電(dian)電(dian)源(yuan)的電(dian)壓是否與PLC一致（若PLC為(wei)24伏供(gong)電(dian)，而(er)電(dian)源(yuan)為(wei)220V，則(ze)PLC已(yi)損壞(huai)；若PLC為(wei)220V供(gong)電(dian)，而(er)電(dian)源(yuan)為(wei)24V，則(ze)PLC不會受損，但(dan)無(wu)法(fa)工(gong)作）；正負(fu)接線是否一致；

若所有可能因素均檢查(cha)無誤，則也可能是PLC硬件(jian)問題，需返廠質保或檢修

西門(men)子(zi)(zi)CPU319上電(dian)(dian)(dian)指示(shi)燈(deng)全亮的(de)(de)(de)問題，?通常(chang)是(shi)(shi)由于(yu)硬件問題或供電(dian)(dian)(dian)、?存儲芯片、?復(fu)位時(shi)鐘等(deng)故障導(dao)致的(de)(de)(de)。?這(zhe)種(zhong)故障的(de)(de)(de)處(chu)理方法主要是(shi)(shi)維修，?而不是(shi)(shi)更(geng)換。?維修西門(men)子(zi)(zi)PLC的(de)(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)模(mo)塊(kuai)時(shi)，?可(ke)以通過觀察工(gong)(gong)作(zuo)指示(shi)燈(deng)的(de)(de)(de)狀態來判斷電(dian)(dian)(dian)源(yuan)(yuan)是(shi)(shi)否正常(chang)。?例如(ru)，?“AC"燈(deng)表示(shi)交流(liu)總電(dian)(dian)(dian)源(yuan)(yuan)，?如(ru)果(guo)不亮，?可(ke)能表示(shi)無(wu)工(gong)(gong)作(zuo)電(dian)(dian)(dian)源(yuan)(yuan)，?整(zheng)個PLC停止(zhi)工(gong)(gong)作(zuo)。?而“5VDC"、?“24VDC"燈(deng)熄滅則表示(shi)無(wu)相(xiang)應的(de)(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)源(yuan)(yuan)輸(shu)出，?當電(dian)(dian)(dian)源(yuan)(yuan)偏(pian)差超出正常(chang)值5%時(shi)，?指示(shi)燈(deng)會閃(shan)爍，?這(zhe)時(shi)雖然PLC仍(reng)能工(gong)(gong)作(zuo)，?但應引起重視，?必要時(shi)停機檢修。?“BATT"變色(se)(se)燈(deng)是(shi)(shi)后備電(dian)(dian)(dian)源(yuan)(yuan)指示(shi)燈(deng)，?黃色(se)(se)表示(shi)電(dian)(dian)(dian)量低，?紅色(se)(se)表示(shi)故障，?黃燈(deng)亮時(shi)就應該更(geng)換后備電(dian)(dian)(dian)池。?
