效益

简单、的工程组态

  与在标准系统中一样，SIMATIC S7400H 可以使用所有 STEP 7 编程语言进行编程。可以很容易的把程序从标准系统迁移到冗余系统中，反之亦然。当加载程序时，它会自动传送到两个冗余控制器中。使用 STEP 7，可以对特定冗余功能和配置进行参数设置。

出色的诊断和模块更换优势   

■  利用集成的自我诊断功能，系统可以提前检测故障和发送信号，避免故障对生产过程产生影响。这样可以有针对性地替换故障组件，加快维修进程。

■   可以在系统运行过程中对所有组件进行热插拔。更换一个 CPU 后，当前的所有程序和数据可以自动重新装载。

■   即使在系统运行过程中，也可以修改程序（例如，程序块的修改和重新装载），更改配置（例如，增加或删减 DP从站或模块）以及改变 CPU 的内存分配。
