:洛陽(yáng)2098-DSD-HV030 AB伺服驅(qū)動(dòng)器 羅克韋爾價(jià)格下面用一個(gè)簡(jiǎn)單的啟停與自鎖電路示例來(lái)說(shuō)明。根據(jù)上圖編制的不能運(yùn)行的錯(cuò)誤PLC程序如下:PLC上電后,X000、X002常閉點(diǎn)就會(huì)斷開(kāi)。即邏輯值為“0”Y0=(Y0+X001)×X000×X002從上面數(shù)字邏輯表達(dá)式可知,在按下啟動(dòng)按鈕SB1后,X001的邏輯值為“1”,而Y0的邏輯值永遠(yuǎn)不會(huì)變化,始終為“0”。原因是與PLC內(nèi)部輸入電路有關(guān),以下是PLC內(nèi)部輸入等效電路:正確的PLC程序如下:PLC上電后,X000、X002常開(kāi)點(diǎn)就會(huì)閉合。
