3517ETRICONEX卡件功率模块 可编程逻辑控制器
TRICON系统是具有冗余和容错能力的三重化控制系统
>从输入模件到MP到输出模件的完全的三重化每一个IO信号都拥有相互立的三个Leg
每一个Leg自主地读取输入信号并将读到状态送给相应的MP三个主处理器之间通过TriBus进行通讯
每一个扫描周期每个MP都会通过TriBus与其他两个MP进行通讯和同步
>TriBus把DI的表决结果和Al的计算结果送给每一个MP
≥每个MP立地进行Program的运算并将结果送到送出模件>输出数据在尽量靠近现场设备的地方进行表决((输出卡的末端)
The TRICON system is a triplex control system with redundancy and fault tolerance
> Complete tripling from input module to MP to output module Each IO signal has three legs standing on top of each other
Each Leg autonomously reads the input signal and sends the read status to the corresponding MP. The three main processors communicate with each other via TriBus
Each MP communicates and synchronizes with the other two MP's via TriBus per scan cycle
>TriBus Sends DI voting results and Al calculations to each MP
≥ Each MP performs the Program operation and sends the result to the outgoing module > The output data is voted on as close as possible to the field equipment ((end of the output card)
