引用第11樓文杰工控學(xué)習于2017-11-14 15:57發(fā)表的  :
監控PLC的話(huà)一般會(huì )用的PLC 的模擬量模塊或者變頻器直接與PLC通訊，這樣會(huì )用到PLC，
還有一種方式就是變頻器與觸摸屏或上位機直接通訊，如果你們原來(lái)沒(méi)有用這種方式，請勿咯，改起來(lái)麻煩


最后你說(shuō)你們的PLC 損壞了，那么你們的PLC只是控制變頻器嗎，沒(méi)有控制其他的負載或者傳感器嗎，如果有的話(huà)那PLC就維修一下或換新的吧

非常感謝您的解答，PLC只是控制變頻器的，沒(méi)有其他的負載了，再次感謝�。�！
