时间节点

当两两个系统同步时，时间节点(%S3, %S4, %S5, %S6)在两两个单元中有相同的值。例如，不论何时，当一个单元的T_ SEC值为on时，只要两两个单元同步运行，另一个单元汇总的此值也必定为on。

混合型I/O扫描设置

冗余的CPU指示混合型扫描的设置。但是，强烈推荐冗余的I/0被设置成默认的扫描类型(扫描设置参数为1)，这样每个周期扫描-次。I/0扫描的设置特征允许/0点的扫描更接近用户逻辑中要使用此点的地方。

I/O扫描设置成不是每个周期扫描一次会导致在首要单元和备用单元中不是同时扫描到此I/O的值。例如，如果首要和备用CPU被设置成隔周期扫描一次(period 参数设置为2) ,首要CPU可能会在第一个周期扫描此点而备用CPU在下一个周期扫描此点。

使用非默认的扫描设置会造成CPU之间到达同步点的延迟。在确定“失败等待时间”参数时要考虑这一点。 

停止到运行状态的切换

在所有的停止到运行模式切换的同时会发生重新同步的动作。执行重新同步的时间会比非冗余状态下由停止切换到运行的时间更长。由停止切换到运行状态有两种不同的途径。

1. 如果一个单元自己切换到运行状态或者两两个单元几乎同时切换到运行状态，会执行正常的停止到运行的切换(清除非保存型的内存并初始化#FST_ _SCN和#FST_ EXE)。

2.如果一个单元在切换到运行模式的同时另一个单元正在运行模式，单元清除非保持型参数后会执行与正在运行的单元的重新同步过程。
