外部設(she)備故障(zhang)。

外部設(she)備就是指與(yu) PLC工作過程直接聯系的各種開關(guan)、 傳(chuan)感器(qi)、 執行機構(gou)、 負載等。 這些設(she)備發生故障(zhang),會直接影(ying)響 PLC 系統的控制功能。因此(ci),維修 PLC ,首先要(yao)分清是外部設(she)備故障(zhang),還是 PLC 本(ben)身故障(zhang)。
　
西門子PLC1516控制器啟動屏幕不亮維修電話2 系統故障。
1系統(tong)故(gu)(gu)障(zhang)是影響 PLC 系統(tong)運行(xing)的(de)全(quan)局性故(gu)(gu)障(zhang)。
2 PLC 系(xi)統故障可以分(fen)為固(gu)定性(xing)故障、偶(ou)然性(xing)故障。
3故障發生(sheng)后,可(ke)以重(zhong)新啟(qi)動(dong)使系(xi)統恢(hui)(hui)復(fu)正(zheng)常,則就是(shi)偶然性故障。如果重(zhong)新啟(qi)動(dong)不能恢(hui)(hui)復(fu), 而是(shi)需要更換硬件(jian)(jian)或軟件(jian)(jian), 系(xi)統才能夠(gou)恢(hui)(hui)復(fu)正(zheng)常, 則認為是(shi)固(gu)定性故障。
