设计和功能

根据统计数字表明，所有自动化组件（无论是机械式、机电式，还是电子式）都会出现故障。因此，工厂维护和工厂改造也就必不缺少。在实际应用中，期待的可用性是不现实的。

通过西门子 SIMATIC S7400H，能够较大限度地降低生产故障机率，较大化生产率。

  SIMATIC S7400H 具有以下功能：

  ■ 出现故障时，能够无扰切换

  ■ 集成故障检测功能；提前检测故障，避免影响生产过程

  ■ 在线维护，即可在工厂运行期间，更换故障组件

  ■ 组态更改，即可在工厂运行期间，进行工厂扩容

  ■ 自动事件同步

  ■ 高可用性通信

  ■ 冗余连接I/O 设备
