RTU的通訊和 由于RTU是專用的器件，現在還沒有統(tǒng)一的，尤其是在通訊方面，通常情況下一個產家的RTU是不能和另一個產家的RTU混用的。協議的轉化和競爭已經形成了一個產業(yè)。近期自動化學會專家會將向市場發(fā)布RTU的通用，這些大致包括如下： @ 通信DNPs和IEC870。 @ RTU編程IEC1131-3。 處理器單元可以包含一個內置的或的modem。這些modems可以通過無條件租借的聲音級電話線或類似的聲道如：微波、無線電、光纖。也可以用異步串行數據端口來代替modem，來擴展通訊設備大可達36.6Kbaud。 處理器連續(xù)的選擇輸入通道將當前的狀態(tài)或模擬量和以前的狀態(tài)作對比。如果模擬量的改變超過了死區(qū)限，就會向監(jiān)控中心通知發(fā)生了狀態(tài)改變；如果沒有改變發(fā)生，一個簡短的確認會返回到監(jiān)控中心。所有其他的信息都是在連續(xù)選取信息將交叉存取的，在忽略選取掃描時間沖突時，優(yōu)的響應時間。
