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。
