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(xún)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。
