1. 設計和功能
根據(jù)統(tǒng)計數(shù)字表明，所有自動化組件（無論是機械式、機電式，還是電子式）都會出現(xiàn)故障。因此，工廠維護和工廠改造也就必不缺少。在實際應用中，期待的可用性是不現(xiàn)實的。通過西門子 SIMATIC S7-400H，能夠較大限度地降低生產(chǎn)故障機率，較大化生產(chǎn)率。
SIMATIC S7-400H 具有以下功能：出現(xiàn)故障時，能夠無擾切換。 集成故障檢測功能；提前檢測故障，避免影響生產(chǎn)過程。在線維護，即可在工廠運行期間，更換故障組件。組態(tài)更改，即可在工廠運行期間，進行工廠擴容。自動事件同步，高可用性通信，冗余連接I/O 設備。
S7-400 PNH CPU的同步分為兩種，一種用于長10m 的 FOC patch 光纖，另一種用于長10km 的單模全雙工 LC/LC 光纖（9/125 μ）。冗余系統(tǒng)的同步光纖分為1m、2m、10m 和10km 四種。同步速率達到400Mbps。
