　　　來(lái)自電源的干擾
　　實(shí)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(diào)試中遇到過(guò)，后更換隔離性能更高的PLC電源，問(wèn)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(xiàn)路上感應(yīng)電壓和電路。尤其是電網(wǎng)內(nèi)部的變化，入開(kāi)關(guān)操作浪涌、大型電力設(shè)備起停、交直流轉(zhuǎn)動(dòng)裝置引起的諧波、電網(wǎng)短路暫態(tài)沖擊等，都通過(guò)輸電線(xiàn)路到電源邊。PLC電源通常采用隔離電源，但其機(jī)構(gòu)及制造工藝因素使其隔離性并不理想。實(shí)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。
