控制器包含三个MP。每个MP控制一个单独的通道，并与其他两个MP并行运行。每个MP上的专用I/O控制处理器管理MP和/O模块之间交换的数据。位于底板上的三重/O总线使用I/O总线电缆从一列/O模块延伸到另一列I/O 模块。轮询每个输入模块时，/O总线的相应通道将新的输入数据传输到其MP。输入数据被组装到MP中的表格中，并存储在内存中，以便在投票过程中使用。每个MP中的单个输入表通过TriBus传输到其相邻MP。在此转移之后，将进行投票。TriBus使用具有 直接存储器访问功能的可编程设备来同步，传输和比较三个MP之间的数据。如果发生分歧，则以三个表中两个表中的信号值为准，第三个表将相应地更正。由样本时序变化导致的-次性差异与不同数据的模式区分开来。每个MP在本地内存中维护有关必要更正的数据。任何差异都会被标记出来，并在扫描结束时由内置的故障分析器例程使用，以确定特定模块上是否存在故障。MP将更正的数据发送到应用程序。32 位MP与相邻MP并行执行应用程序，并根据用户定义的规则生成基于输入值表的输出值表。每个MP上的/O控制处理器通过/O总线管理输出数据传输到输出模块。 The controller contains three MPs. Each MP controls a separate channel and runs in parallel with the other two MPs. The dedicated I/O control processor on each MP manages the data exchanged between the MP and/O modules. The triple/O bus located on the backplane uses I/O bus cables to extend from one row of/O modules to another row of I/O modules. When polling each input module, the corresponding channel of the/O bus transmits new input data to its MP. The input data is assembled into tables in MP and stored in memory for use during the voting process. The individual input table in each MP is transmitted to its adjacent MP through TriBus. After this transfer, voting will take place. TriBus uses programmable devices with direct memory access to synchronize, transmit, and compare data between three MPs. If there is a disagreement, the signal values in two of the three tables shall prevail, and the third table shall be corrected accordingly. Distinguish secondary differences caused by changes in sample timing from patterns of different data. Each MP maintains data related to necessary corrections in local memory. Any differences will be marked and used by the built-in fault analyzer routine at the end of the scan to determine if a fault exists on a specific module. MP sends the corrected data to the application. 32-bit MP executes the application program in parallel with adjacent MPs, and generates an output value table based on the input value table according to user-defined rules. The/O control processor on each MP manages the transmission of output data to the output module through the/O bus.
