信號(hào)準(zhǔn)確地輸入給PLC后，PLC執(zhí)行程序，將結(jié)果通過(guò)執(zhí)行機(jī)構(gòu)對(duì)現(xiàn)場(chǎng)裝置進(jìn)行調(diào)節(jié)、控制。怎樣保證執(zhí)行機(jī)構(gòu)按控制要求工作，當(dāng)執(zhí)行機(jī)構(gòu)沒(méi)有按要求工作，怎樣發(fā)現(xiàn)故障？我們采取以下措施：當(dāng)負(fù)載由接觸器控制時(shí)，啟動(dòng)或停止這類負(fù)載轉(zhuǎn)為對(duì)接觸器線圈控制，啟動(dòng)時(shí)接觸器是否可靠吸合，停止時(shí)接觸器是否可靠釋放，這是我們關(guān)心的。

    X0為接觸器動(dòng)作條件，Y0為控制線圈輸出，X1為引回到PLC輸入端的接觸器輔助常開(kāi)觸點(diǎn)，定時(shí)器定時(shí)時(shí)間大于接觸器動(dòng)作時(shí)間。R0為設(shè)定的故障位，R0為ON表示有故障，做報(bào)警處理；R0為OFF表示*。故障具有記憶功能，由故障復(fù)位按鈕清除。

    當(dāng)開(kāi)啟或關(guān)閉電動(dòng)閥門時(shí)，根據(jù)閥門開(kāi)啟、關(guān)閉時(shí)間不同，設(shè)置延時(shí)時(shí)間，經(jīng)過(guò)延時(shí)檢測(cè)開(kāi)到位或關(guān)到位信號(hào)，如果這些信號(hào)不能按時(shí)準(zhǔn)確返回給PLC，說(shuō)明閥可能有故障，做閥故障報(bào)警處理。程序設(shè)計(jì)如圖3b 所示。X2為閥門開(kāi)啟條件，Y1為控制閥動(dòng)作輸出，定時(shí)器定時(shí)時(shí)間大于閥開(kāi)啟到位時(shí)間，X3為閥到位返回信號(hào)，R1為閥故障位
