RTU的通訊和標(biāo)準(zhǔn) 由于RTU是專用的器件，現(xiàn)在還沒有統(tǒng)一的標(biāo)準(zhǔn)，尤其是在通訊方面，通常情況下一個產(chǎn)家的RTU是不能和另一個產(chǎn)家的RTU混用的。協(xié)議的轉(zhuǎn)化和競爭已經(jīng)形成了一個產(chǎn)業(yè)。近期中國自動化學(xué)會專家咨詢委員會將向市場發(fā)布RTU的通用標(biāo)準(zhǔn)，這些標(biāo)準(zhǔn)大致包括如下： @ 通信標(biāo)準(zhǔn)DNPs和IEC870。 @ RTU編程標(biāo)準(zhǔn)IEC1131-3。 中央處理器單元可以包含一個內(nèi)置的或獨立的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(shù)據(jù)端口來代替modem，來擴展通訊設(shè)備最大可達(dá)36.6Kbaud。 中央處理器連續(xù)的選擇輸入通道將當(dāng)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(rèn)信號會返回到監(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，獲得最優(yōu)的響應(yīng)時間。
RTU（遠(yuǎn)程測控終端），英文全稱 Remote Terminal Unit，中文全稱為遠(yuǎn)程終端控制系統(tǒng)，負(fù)責(zé)對現(xiàn)場信號、工業(yè)設(shè)備的監(jiān)測和控制。其中包括：開關(guān)量輸入單元、開關(guān)量輸出單元、模擬量輸入單元、模擬量輸出單元、脈沖量輸入單元、脈沖量輸出單元、數(shù)字量輸入單元。
開關(guān)量輸入單元：對現(xiàn)場各種開關(guān)信號的采集，現(xiàn)場信號可以是繼電器觸點開關(guān)（無源），也可以是電壓信號，還可以是電流信號。由于采用光隔離器件，可以抵抗現(xiàn)場各種干擾，能夠在強電場、強磁場、多塵埃、潮濕環(huán)境下正常工作。
開關(guān)量輸出單元：用于遙控遠(yuǎn)端設(shè)備的開停、聲光、告警等。
