大容量值，这些信号用一内部振荡器的载波频率进行宽调制，这样，得到能通过容性屏障的高
频信号。调制输入时，需要一个低通滤波器(LPF)将高频载波从实际数据中除掉，然后再到达
输出多路器。图2和图3给出了高频通道和低频通道及相应的代表性波形。
将单端输入信号分离成微分信号分量A和/A。每个信号分量然后再微分成瞬变B和/B。
跟随的比较器对瞬变进行比较。只要比较器正输入的电位高于负输入端电位，比较器输出即为
逻辑高，这样就将输入瞬变转换成了短输出脉冲了。
输出脉冲置位及复位‘或非'门跳转。我们可以从真值表看出，‘或非’门配置有 一个反向跳
转，即输入C的高电平将输出/D置为高，而/C为高电平则将D置为高。因为比较器输出脉冲
持续时间短，就可能出现两个输出都为低的情况。这时，跳转将其之前的输出状态存储了下
来。由于/D的信号与输入信号在形状和相位上都相同，/D就成为了高速通道的输出而与输出
多路器相连。

隔离工业接口时，需要区分过程控制和工厂自动化应用。这是因为两者之间的差别会影响
到数字接口设计的隔离工作。过程控制一般涉及到检测某些设备、系统或过程的不同物理量
(如压力“与”温度)。每一个物理量都用--特定类型的传感器或变换器，其输出信号需要特定
的信号调理。因此，多种不同的传感器需要不同的参数设置，如内部增益、采样率、测量重复
性、以及阻抗缓冲。支持宽范围设置的ADC提供有多个接口控制线，除标准串行接口线要求
隔离之外，所有这些控制线也都要求隔离。
图4中，许多不同灵敏度(mV/K)的传感器测量不同的过程参数，如温度、压力和电流。要

求有多种增益设置来使各传感器的ADC的输入动态范围最大化。如果期望-一个或多个通道输
入变化能比别的通道快，可能就要求采样率(速度)之间有切换。降低功率功能用来节省测量
后的功耗，此功能可使控制器执行其它系统功能。这种高度多功能性要求许多控制通道用两个
四路隔离器隔离。
与过程控制相比，工厂自动化常涉及监测多个器件和设备的单个物理量(如温度‘或压
力)。因此，这些系统采用多个同类型传感器，灵敏度和响应时间一致。

西门子模块固件版本为什么要一致
a西门子PLC及其模块除了订货号外，还有硬件版本号和固件版本号，其中模块右下方的十字上字母X与3个数字为硬件版本号，如X2/3/4为V1版本；而6/7/8为V5版本；而软件版本号是你在硬件组态时插入模块时选择的具体模块版本号；
