大容量值，這些信號用一內(nèi)部振蕩器的載波頻率進行寬調(diào)制，這樣，得到能通過容性屏障的高
頻信號。調(diào)制輸入時，需要一個低通濾波器(LPF)將高頻載波從實際數(shù)據(jù)中除掉，然后再到達
輸出多路器。圖2和圖3給出了高頻通道和低頻通道及相應(yīng)的代表性波形。
將單端輸入信號分離成微分信號分量A和/A。每個信號分量然后再微分成瞬變B和/B。
跟隨的比較器對瞬變進行比較。只要比較器正輸入的電位高于負輸入端電位，比較器輸出即為
邏輯高，這樣就將輸入瞬變轉(zhuǎn)換成了短輸出脈沖了。
輸出脈沖置位及復(fù)位‘或非'門跳轉(zhuǎn)。我們可以從真值表看出，‘或非’門配置有 一個反向跳
轉(zhuǎn)，即輸入C的高電平將輸出/D置為高，而/C為高電平則將D置為高。因為比較器輸出脈沖
持續(xù)時間短，就可能出現(xiàn)兩個輸出都為低的情況。這時，跳轉(zhuǎn)將其之前的輸出狀態(tài)存儲了下
來。由于/D的信號與輸入信號在形狀和相位上都相同，/D就成為了高速通道的輸出而與輸出
多路器相連。

隔離工業(yè)接口時，需要區(qū)分過程控制和工廠自動化應(yīng)用。這是因為兩者之間的差別會影響
到數(shù)字接口設(shè)計的隔離工作。過程控制一般涉及到檢測某些設(shè)備、系統(tǒng)或過程的不同物理量
(如壓力“與”溫度)。每一個物理量都用--特定類型的傳感器或變換器，其輸出信號需要特定
的信號調(diào)理。因此，多種不同的傳感器需要不同的參數(shù)設(shè)置，如內(nèi)部增益、采樣率、測量重復(fù)
性、以及阻抗緩沖。支持寬范圍設(shè)置的ADC提供有多個接口控制線，除標準串行接口線要求
隔離之外，所有這些控制線也都要求隔離。
圖4中，許多不同靈敏度(mV/K)的傳感器測量不同的過程參數(shù)，如溫度、壓力和電流。要

求有多種增益設(shè)置來使各傳感器的ADC的輸入動態(tài)范圍最大化。如果期望-一個或多個通道輸
入變化能比別的通道快，可能就要求采樣率(速度)之間有切換。降低功率功能用來節(jié)省測量
后的功耗，此功能可使控制器執(zhí)行其它系統(tǒng)功能。這種高度多功能性要求許多控制通道用兩個
四路隔離器隔離。
與過程控制相比，工廠自動化常涉及監(jiān)測多個器件和設(shè)備的單個物理量(如溫度‘或壓
力)。因此，這些系統(tǒng)采用多個同類型傳感器，靈敏度和響應(yīng)時間一致。

西門子模塊固件版本為什么要一致
a西門子PLC及其模塊除了訂貨號外，還有硬件版本號和固件版本號，其中模塊右下方的十字上字母X與3個數(shù)字為硬件版本號，如X2/3/4為V1版本；而6/7/8為V5版本；而軟件版本號是你在硬件組態(tài)時插入模塊時選擇的具體模塊版本號；
