 問題反映：PLC到TP270直線距離大概有20米，通訊線放電纜槽溝內長度大約有35米，PLC柜緊挨著直流傳動柜，直流傳動柜旁邊是低壓柜(內有液壓站電機、主電機風機的接觸器、保護器，低壓開關、微斷等，還有幾臺變頻器)，所有的電纜都在一個電纜溝里，有較大部分的平行放置；變頻器與直流傳動均沒有與PLC實現網絡通信，所有的運行指令及速度值由PLC輸出，PLC通過電纜與相關設備連接。
      解決方案：變頻器和TP通信線是否有屏蔽？變頻器的布線和屏蔽如果處理得不好的話，可能會產生很重的干擾。
       是否可以試試將TP暫時放PLC旁邊，或者臨時拉一條通信電纜（不要放電纜溝）。如果沒問題的話，說明是干擾的問題。
       問題反映：變頻器功率不大，5.5Kw，但是變頻器與TP沒有通訊。PLC與TP通訊電纜是西門子電纜，屏蔽層接數據地線，但這根電纜與多根大電流的電纜平行放置，長度大約15米．
       已經將TP放在PLC旁邊，沒有任何問題的，今天準備更換一根通訊電纜，而且遠離動力電纜，不知是否有效果。PLC端的RS485總線插頭的終端電阻不接，TP端的終端電阻接入。

解決方案：如果只是PLC和TP的點對點通信，雙方都應該接入終端電阻。
      問題反映：采用了上次提出的方法，兩端都接入終端電阻，但是還頻繁地出通訊中斷的提示，等大修時間在更換一下動力電纜再看看效果。
      總結：通過實驗，可以肯定干擾的根本原因是通信電纜與多根大電流的電纜（特別是變頻器的輸入、輸出電纜）平行放置在同一電纜溝內，且距離很近。
       這個系統(tǒng)比較簡單，只是點對點通信，zui簡單的實驗方法就是將兩臺設備暫時放置在一起，或者臨時拉一條通信電纜（不要放電纜溝）。如果干擾消失，肯定是電纜布線引入的干擾。可以用示波器觀察RS-485的A、B線對數字地（5針）的波形，如果有強烈干擾，可以看得到干擾信號的波形。
