2.产 品 详 情 资 料:
WOODWARD 5466-332 I/O单元通过光模块总线和每个S800 I/O集群上的两个TB840集群调制解调器连接到两个CPU(参见第161页的图55)。TP830基板上的内置电气模块总线不能用于连接冗余系统中的S800 I/O。PM891中的冗余链路由两个物理链路组成。这是RCU数据链路和RCU控制链路。RCU数据链路是一个快速通信信道,用于传输保持备份CPU与主CPU同步所需的数据。WOODWARD 5466-332数据链路电缆用于数据链路。RCU控制链路用于角色选择和CPU标识分配(UPPER/LOWER)。WOODWARD 5466-332控制链路电缆用于控制链路。容错原则冗余处理器单元的容错原则是基于备份单元不断更新到与主单元相同的状态。这使得备份单元能够在不影响周围系统的情况下进行控制。该原理涉及将程序执行动态划分为执行单元,并创建回滚点,在回滚点处处理器单元的状态被完全定义。
S800 I/O units are connected to the two CPUs via the optical ModuleBus and two TB840 cluster modems on each S800 I/O clusterWOODWARD 5466-332 The built-in electrical ModuleBus on the TP830 baseplate cannot be used for connecting S800 I/O in a redundant system.The Redundancy Link in PM891 consists of two physical links. These are the RCU Data Link and the RCU Control Link. The RCU Data Link is a fast communication channel used to transfer the data required to keep the backup CPU synchronized with the primary CPU.WOODWARD 5466-332 Data Link Cable is used for the data link. The RCU Control Link is used for role selection and CPU identity assignment (UPPER/LOWER). TK856 RCU Control Link Cable is used for the control link. Fault Tolerance Principle The principle of fault tolerance in the redundant processor units is based on continuous updating of the backup unit to the same status as the primary unit. This enables the backup unit to assume control without affecting surrounding systems in a bumpless manner. This principle involves dynamic division of the program execution into execution units and the creation of rollback points at which the processor unit's status is completely defined.WOODWARD 5466-332
