維修PLC先后順序是怎樣的？
先動(dòng)口再動(dòng)手
1）維修PLC時(shí)，不要立即直接動(dòng)手，而是先詢問(wèn)故障發(fā)生前后的情況、故障現(xiàn)象。
2）如果對(duì)生疏的PLC維修，應(yīng)先了解其工作原理。
先清潔再維修
維修PLC時(shí)，可以打開(kāi)機(jī)子，首先進(jìn)行清潔PLC。
先外后內(nèi)
維修PLC時(shí)，先檢查外部現(xiàn)象與原因，如果外部正常，則然后檢查PLC內(nèi)部。
先無(wú)電判斷后通電判斷
首先在沒(méi)有通電的情況下，先判斷熔絲是否損壞、是否不通電就可以判斷出故障點(diǎn)。如果不能夠判斷出來(lái)，則再通電檢查PLC。

查找一般PLC故障的步驟是怎樣的？
PLC維修時(shí)，插好編程器，并將開(kāi)關(guān)撥到RUN位置，再根據(jù)下列步驟查找：
1）如果PLC停止在某些輸出被激勵(lì)的位置、狀態(tài)（地方），一般是處于中間狀態(tài)，則查找引起下一步操作發(fā)生的信號(hào)，編程器會(huì)顯示信號(hào)的ON/OFF狀態(tài)。
2）如果輸入信號(hào)，將編程器顯示的狀態(tài)與輸入模塊的LED指示作比較，若結(jié)果不一致，則說(shuō)明需要更換輸入模塊。更換模塊前，需要先檢查I/O擴(kuò)展電纜和相關(guān)連接是否正常。
3）如果輸入狀態(tài)與輸入模塊的LED指示一致，則比較發(fā)光二極管與輸入裝置的狀態(tài)。如果兩者不同，則需要測(cè)量一下輸入模塊。如果發(fā)現(xiàn)存在問(wèn)題，則需要更換I/O裝置、現(xiàn)場(chǎng)接線、電源等。否則，需要更換輸入模塊。
4）如果信號(hào)是線圈，沒(méi)有輸出或輸出與線圈的狀態(tài)不同，則需要用編程器檢查輸出的驅(qū)動(dòng)邏輯，并檢查程序清單。
5）如果信號(hào)是定時(shí)器，并停在小于999.9的非零值上，則需要更換CPU模塊。
6）如果該信號(hào)控制一個(gè)計(jì)數(shù)器，則需要先檢查控制復(fù)位的邏輯，再檢查計(jì)數(shù)器信號(hào)。然后檢查、判斷相關(guān)組件是否異常，需要更換。
