各位大俠:有這么個(gè)情況向大家求助,歐姆龍CP1H的輸入點(diǎn)將0.04的信號(hào)線(xiàn)拆開(kāi),給0.03點(diǎn)按按鈕輸入一個(gè)信號(hào)后,0.03和0.04兩個(gè)點(diǎn)的輸入指示燈會(huì)同時(shí)亮,且其對(duì)應(yīng)的輸出點(diǎn)會(huì)有輸出,但把0.04接上線(xiàn)號(hào)線(xiàn)后給輸入信號(hào)后0.04輸入指示燈不會(huì)亮,且其對(duì)應(yīng)的輸出點(diǎn)沒(méi)有輸出,請(qǐng)高手指點(diǎn)一下這到底是PLC的0.04點(diǎn)壞了,還是有其它什么原因
