2.产 品 详 情 资 料：
WOODWARD 5464-843在重新执行期间，使用已经执行的外围单元引用的结果，而不是重新执行它们。读取操作的结果将从日志中检索，而写入操作将在不执行的情况下传递，因为它们已经执行。因此，除了发生的时间延迟外，外围设备的状态不会以任何方式受到重新执行的影响。处理器单元中包含的RAM提供自动双反转存储器功能，WOODWARD 5464-843用于检测存储器中的任意位错误。•所有内存更新都并行写入主内存和反向内存。•在每个内存读取周期，比较两个内存的数据。•如果数据不匹配，则强制转换。双反转内存处理是在硬件中完成的，不会对内存周期时间造成任何延迟。冗余配置中的MAC和IP地址处理为了提供与控制网络相关的无扰切换，MAC地址和IP地址在初始主CPU和备用CPU之间交换。初始主CPU的地址被存储并保持为代理主CPU使用的地址WOODWARD 5464-843
During re-execution, the results of the peripheral units' references, which have already been executed, are used, rather than re-executing them. The results of read operations are retrieved from the log, and write operations pass without execution,WOODWARD 5464-843 since they have already been executed. The peripheral units' statuses, then, are not affected by the reexecution in any way, except for the time delay which occurs. The RAM included in the processor unit provides an automatic double inverted memory function for detection of arbitrary bit errors in the memory. • All memory updates are written to both the primary memory and to the inverted memory in parallel. • At every memory read cycle, the data from tho two memories is compared. • If there is a mismatch in the data a changeover is forced. The double inverted memory handling is done in hardware and without any delay to the memory cycle time.MAC and IP Address Handling in Redundant Configuration In order to provide for a bumpless changeover with respect to the control network, both the MAC and IP addresses are swapped between the initial primary and backup CPUs. The addresses of the initial primary CPU are stored and kept as the addresses used by the acting primary CPUWOODWARD 5464-843
