影響現(xiàn)場輸入給PLC信號出錯的主要原因有：
1)造成傳輸信號線短路或斷路（由于機(jī)械拉扯，線路自身老化，特別是鼠害），當(dāng)傳輸信號線出故障時(shí)，現(xiàn)場信號無法傳送給PLC，造成控制出錯；
2)機(jī)械觸點(diǎn)抖動，現(xiàn)場觸點(diǎn)雖然只閉合一次，PLC卻認(rèn)為閉合了多次，雖然硬件加了濾波電路，軟件增加微分指令，但由于PLC掃描周期太短，仍可能在計(jì)數(shù)、累加、移位等指令中出錯，出現(xiàn)錯誤控制結(jié)果；
3)現(xiàn)場變送器，機(jī)械開關(guān)自身出故障，如觸點(diǎn)接觸不良，變送器反映現(xiàn)場非電量偏差較大或不能正常工作等，這些故障同樣會使控制系統(tǒng)不能正常工作。
影響執(zhí)行機(jī)構(gòu)出錯的主要原因有：
1)控制負(fù)載的接觸不能可靠動作，PLC發(fā)出了動作指令，但執(zhí)行機(jī)構(gòu)并沒按要求動作；
2)控制變頻器起動，由于變頻器自身故障，變頻器所帶電機(jī)并沒按要求工作；
3)各種電動閥、電磁閥該開的沒能打開，該關(guān)的沒能關(guān)到位，由于執(zhí)行機(jī)構(gòu)沒能按PLC的控制要求動作，使系統(tǒng)無法正常工作，降低了系統(tǒng)可靠性。要提高整個(gè)控制系統(tǒng)的可靠性，必須提高輸入信號的可靠性和執(zhí)行機(jī)構(gòu)動作的準(zhǔn)確性，否則PLC應(yīng)能及時(shí)發(fā)現(xiàn)問題，用聲光等報(bào)*辦法提示給操作人員，盡快排除故障，讓系統(tǒng)安全、可靠、正確地工作。
