西門子S7-1500 CPU上的小面板黑屏不亮,西門子PLC1500上電指示燈亮屏幕無反應,不啟動不開機修復解決
故障(zhang)處理;首先,檢(jian)查接線:電(dian)(dian)(dian)源線是不(bu)是已經連(lian)接到(dao)供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)源端(duan)子(PLC一(yi)般有多(duo)組電(dian)(dian)(dian)源端(duan)子,分為三(san)種類似:模(mo)塊供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)源、輸(shu)入傳感器電(dian)(dian)(dian)源、輸(shu)出驅(qu)動電(dian)(dian)(dian)源);
其(qi)次,檢查電(dian)(dian)源(yuan):外部供(gong)(gong)電(dian)(dian)電(dian)(dian)源(yuan)的電(dian)(dian)壓是(shi)(shi)否與PLC一(yi)致(zhi)(若(ruo)PLC為(wei)(wei)24伏供(gong)(gong)電(dian)(dian),而電(dian)(dian)源(yuan)為(wei)(wei)220V,則PLC已損壞;若(ruo)PLC為(wei)(wei)220V供(gong)(gong)電(dian)(dian),而電(dian)(dian)源(yuan)為(wei)(wei)24V,則PLC不會受損,但無法(fa)工作);正負接線是(shi)(shi)否一(yi)致(zhi);
若(ruo)所(suo)有可能因素均檢查無誤,則(ze)也(ye)可能是PLC硬(ying)件(jian)問(wen)題,需(xu)返(fan)廠質(zhi)保或檢修(xiu)

西門子PLC S7-1500系列的(de)電(dian)源(yuan)模(mo)(mo)塊(kuai),分為(wei)PS電(dian)源(yuan)模(mo)(mo)塊(kuai)和PM電(dian)源(yuan)模(mo)(mo)塊(kuai)兩種,下面來(lai)分別進行說明:
1. PS電源模(mo)塊
西門(men)子PLC S7-1500系(xi)列的PS電(dian)源(yuan)(yuan)模塊,又稱為系(xi)統(tong)電(dian)源(yuan)(yuan)模塊。它連接到背(bei)板(ban)總(zong)線并專門(men)為背(bei)板(ban)總(zong)線提供內部所需的系(xi)統(tong)電(dian)源(yuan)(yuan),這種系(xi)統(tong)電(dian)源(yuan)(yuan)可為模塊電(dian)子元件和(he)LED指示燈供電(dian)。總(zong)線電(dian)氣隔離和(he)安全電(dian)氣隔離符合EN61131-2標準,支持(chi)固件更新,標識數據,在運(yun)行模式下組態,診斷(duan)報警和(he)診斷(duan)中斷(duan);
2. PM電(dian)源模塊
西門(men)子(zi)PLC S7-1500系(xi)列的PM電(dian)(dian)(dian)(dian)源(yuan)模(mo)塊(kuai),又稱為高(gao)性(xing)能(neng)的負載電(dian)(dian)(dian)(dian)源(yuan)模(mo)塊(kuai)。PM電(dian)(dian)(dian)(dian)源(yuan)模(mo)塊(kuai)為CPU/IM,I/O模(mo)塊(kuai),PS電(dian)(dian)(dian)(dian)源(yuan)等(deng)提供高(gao)效,穩定(ding),可靠(kao)的直流24V供電(dian)(dian)(dian)(dian)。它的輸入電(dian)(dian)(dian)(dian)壓為120V或230V交流電(dian)(dian)(dian)(dian),具有(you)抗過壓性(xing)能(neng)和輸出過壓保護功能(neng),提高(gao)了(le)(le)系(xi)統的安全性(xing)。它具有(you)的啟動(dong)和緩(huan)沖能(neng)力,增強了(le)(le)系(xi)統的穩定(ding)性(xing)。它采(cai)用(yong)*電(dian)(dian)(dian)(dian)路設(she)計和高(gao)品(pin)質的電(dian)(dian)(dian)(dian)子(zi)器件,保證了(le)(le)電(dian)(dian)(dian)(dian)源(yuan)的可靠(kao)性(xing)。并(bing)且具有(you)優異的EMC兼容(rong)性(xing)能(neng),符合西門(men)子(zi)PLC S7-1500系(xi)統的集成要求。
三、總結(jie)
綜上所述,西(xi)門子(zi)PLC S7-1500系(xi)(xi)列在各(ge)個方(fang)面的(de)(de)(de)創新設(she)計,為(wei)(wei)用(yong)戶提供(gong)了更(geng)為(wei)(wei)完善的(de)(de)(de)自(zi)動化控(kong)制系(xi)(xi)統(tong)解(jie)決方(fang)案。它(ta)的(de)(de)(de)擴展(zhan)信號模(mo)塊(kuai)功能強大,設(she)計理念*,幫助用(yong)戶搭建經濟性好,響應快速,運行穩定的(de)(de)(de)控(kong)制系(xi)(xi)統(tong)。用(yong)戶通過(guo)合(he)理的(de)(de)(de)配置西(xi)門子(zi)PLC S7-1500系(xi)(xi)列的(de)(de)(de)電源(yuan)模(mo)塊(kuai),可(ke)以(yi)使得控(kong)制系(xi)(xi)統(tong)發揮(hui)更(geng)好的(de)(de)(de)作用(yong),為(wei)(wei)用(yong)戶在調試和設(she)備(bei)維護(hu)過(guo)程中提高工(gong)作效(xiao)率,為(wei)(wei)企業節約成(cheng)本,帶(dai)來更(geng)大的(de)(de)(de)效(xiao)益。如果用(yong)戶需要更(geng)多(duo)的(de)(de)(de)了解(jie)和使用(yong)西(xi)門子(zi)PLC系(xi)(xi)列,我們也會更(geng)好的(de)(de)(de)提供(gong)相關技術支持。
