就是剛剛PLC的輸入點(diǎn)被別人接進(jìn)了220V的電壓，會(huì )不會(huì )燒掉？他離開(kāi)現場(chǎng)后半個(gè)小時(shí)打電話(huà)給我，接的時(shí)候試車(chē)正常，那會(huì )不會(huì )燒掉PLC

謝謝大家的關(guān)心，一共是兩個(gè)PLC,西門(mén)子200CN的電源板燒了，由于不能解密，就拆了一個(gè)新的PLC電源板換了后正常，謝天謝地程序還在。還有個(gè)是歐姆龍cpm2ah,由于當時(shí)就把電斷掉，只是段短時(shí)間受到220的沖擊，還好一切正常

當然會(huì )燒掉,換個(gè)點(diǎn)就可以了,也可以拆開(kāi)換輸入繼電器.
