(1)來自空間的輻***擾
空間的輻射電磁場（EMI）主要是由電力網(wǎng)絡、電氣設備的暫態(tài)過程、雷電、無線電廣播、電視、雷達、高頻感應加熱設備等產(chǎn)生的，通常稱為輻***擾，其分布極為復雜。若PLC系統(tǒng)置于所射頻場內，就回收到輻***擾，其影響主要通過兩條路徑；一是直接對PLC內部的輻射，由電路感應產(chǎn)生干擾；而是對PLC通信內網(wǎng)絡的輻射，由通信線路的感應引入干擾。輻***擾與現(xiàn)場設備布置及設備所產(chǎn)生的電磁場大小，特別是頻率有關，一般通過設置電纜和PLC局部及高壓泄放元件進行保護。
(2)來自系統(tǒng)外引線的干擾
主要通過電源和信號線引入，通常稱為傳導干擾。這種干擾在我國工業(yè)現(xiàn)場較嚴重。
(3)來自電源的干擾
實踐證明，因電源引入的干擾造成PLC控制系統(tǒng)故障的情況很多，筆者在某工程調試中遇到過，后更換隔離性能更高的PLC電源，問題才得到解決。
PLC系統(tǒng)的正常供電電源均由電網(wǎng)供電。由于電網(wǎng)覆蓋范圍廣，將受到所有空間電磁干擾而在線路上感應電壓和電路。尤其是電網(wǎng)內部的變化，入開關操作浪涌、大型電力設備起停、交直流轉動裝置引起的諧波、電網(wǎng)短路暫態(tài)沖擊等，都通過輸電線路到電源邊。PLC電源通常采用隔離電源，但其機構及制造工藝因素使其隔離性并不理想。實際上，由于分布參數(shù)特別是分布電容的存在，隔離是不可能的。
