隨著科學(xué)技術(shù)的發(fā)展，PLC在工業(yè)控制中的應(yīng)用越來(lái)越廣泛。PLC控制系統(tǒng)的可靠性直接影響到工業(yè)企業(yè)的安全生產(chǎn)和經(jīng)濟(jì)運(yùn)行，系統(tǒng)的抗干擾能力是關(guān)系到整個(gè)系統(tǒng)可靠運(yùn)行的關(guān)鍵。自動(dòng)化系統(tǒng)中所使用的各種類(lèi)型PLC，有的是集中安裝在控制室，有的是安裝在生產(chǎn)現(xiàn)場(chǎng)和各電機(jī)設(shè)備上，它們大多處在強(qiáng)電電路和強(qiáng)電設(shè)備所形成的惡劣電磁環(huán)境中。要提高PLC控制系統(tǒng)可靠性，一方面要求PLC生產(chǎn)廠(chǎng)家用提高設(shè)備的抗干擾能力；另一方面，要求工程設(shè)計(jì)、安裝施工和使用維護(hù)中引起高度重視，多方配合才能完善解決問(wèn)題，有效地增強(qiáng)系統(tǒng)的抗干擾性能。影響PLC控制系統(tǒng)的干擾源與一般影響工業(yè)控制設(shè)備的干擾源一樣，大都產(chǎn)生在電流或電壓劇烈變化的部位，這些電荷劇烈移動(dòng)的部位就是噪聲源，即干擾源。干擾類(lèi)型通常按干擾產(chǎn)生的原因、噪聲干擾模式和噪聲的波形性質(zhì)的不同劃分。其中：按噪聲產(chǎn)生的原因不同，分為放電噪聲、浪涌噪聲、高頻振蕩噪聲等；按噪聲的波形、性質(zhì)不同，分為持續(xù)噪聲、偶發(fā)噪聲等；按噪聲干擾模式不同，分為共模干擾和差模干擾。共模干擾和差模干擾是一種比較常用的分類(lèi)方法。共模干擾是信號(hào)對(duì)地的電位差，主要由電網(wǎng)串入、地電位差及空間電磁輻射在信號(hào)線(xiàn)上感應(yīng)的共態(tài)（同方向）電壓迭加所形成。共模電壓有時(shí)較大，特別是采用隔離性能差的配電器供電室，變送器輸出信號(hào)的共模電壓普遍較高，有的可高達(dá)130V以上。共模電壓通過(guò)不對(duì)稱(chēng)電路可轉(zhuǎn)換成差模電壓，直接影響測(cè)控信號(hào)，造成元器件損壞（這就是一些系統(tǒng)I/O模件損壞率較高的主要原因），這種共模干擾可為直流、亦可為交流。差模干擾是指作用于信號(hào)兩極間的干擾電壓，主要由空間電磁場(chǎng)在信號(hào)間耦合感應(yīng)及由不平衡電路轉(zhuǎn)換共模干擾所形成的電壓，這種讓直接疊加在信號(hào)上，直接影響測(cè)量與控制精度。
