1. 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 S7-400H，能够较大限度地降低生产故障机率，较大化生产率。
SIMATIC S7-400H 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。
S7-400 PNH CPU的同步分为两种，一种用于长10m 的 FOC patch 光纤，另一种用于长10km 的单模全双工 LC/LC 光纤（9/125 μ）。冗余系统的同步光纤分为1m、2m、10m 和10km 四种。同步速率达到400Mbps。
