1、采用性能優(yōu)良的電源，電網(wǎng)引入的干擾
在PLC控制系統(tǒng)中，電源占有極重要的地位。電網(wǎng)干擾串入PLC控制系統(tǒng)主要通過PLC系統(tǒng)的供電電源（如CPU 電源、I/O電源等）、變送器供電電源和與PLC系統(tǒng)具有直接電氣連接的儀表供電電源等耦合進入的?，F(xiàn)在，對于PLC系統(tǒng)供電的電源，一般都采用隔離性能較好電源，而對于變送器供電的電源和PLC系統(tǒng)有直接電氣連接的儀表的供電電源，并沒受到足夠的重視，雖然采取了一定的隔離措施，但普遍還不夠，主要是使用的隔離變壓器分布參數(shù)大，干擾能力差，經(jīng)電源耦合而串入共模干擾、差模干擾。所以，對于變送器和共用信號儀表供電應選擇分布電容小、帶大（如采用多次隔離和及漏感技術）的配電器，以減少PLC系統(tǒng)的干擾。
此外，位保證電網(wǎng)饋點不中斷，可采用在線式不間斷供電電源（UPS）供電，提高供電的安全可靠性。并且UPS還具有較強的干擾隔離性能，是一種PLC控制系統(tǒng)的理想電源。
2、電纜選擇的敖設
為了減少動力電纜輻射電磁干擾，尤其是變頻裝置饋電電纜。筆者在某工程中，采用了銅帶鎧裝電力電纜，從而降低了動力線生產的電磁干擾，該工程投產后取得了滿意的效果。
不同類型的信號分別由不同電纜傳輸，信號電纜應按傳輸信號種類分層敖設，嚴禁用同一電纜的不同導線同時傳送動力電源和信號，避免信號線與動力電纜靠***行敖設，以減少電磁干擾。
