3704E 三重模件冗余(TMR)结构
3704E 模拟输入模块
三重模件冗余(TMR)结构,保证了设备的容错能力,并且能在元部件出现硬件故障或者来自内部或外部来源的瞬态故障的情况下提供完好的不间断的控制。
每一个I/O模件内都包容有三个独立的分电路。输入模件上的每一分电路读取过程数据并将这些信息传送给它相应的主处理器。三个主处理器通过一个专用的呗称作TriBus的高速总线系统通讯

3704E Analog input module
Triple module redundancy (TMR) ensures the device’s fault tolerance and provides intact, uninterrupted control in the event of hardware failure of the component or transient failure from internal or external sources.
Each I/O module contains three separate sub-circuits. Each circuit on the input module reads process data and transmits this information to its corresponding host processor. The three main processors communicate via a dedicated high-speed bus system called TriBus.
