1.產(chǎn)品說明
SIMATICS7-400 PNH系統(tǒng)可以根據(jù)具體應(yīng)用需求量身定制：性能可擴展、冗余度可靈活組態(tài)，安全功能易于集成。集成PROFINET接口，可冗余連接I/O設(shè)備，或者通過PROFIBUS連接I/O設(shè)備，實現(xiàn)工廠通信。無論何種應(yīng)用，使用SIMATIC S7-400 PNH，均可在熟悉的STEP7 工程環(huán)境中，進行便捷而有效的編程和組態(tài)。
2.應(yīng)用
避免控制器故障引起的停機。主要用于生產(chǎn)、能源、供水系統(tǒng)、機場助航照明、編組站系統(tǒng)等域。避免因工廠故障造成數(shù)據(jù)丟失而導(dǎo)致的高昂重啟成本。主要用于行李處理、高架倉庫、跟蹤和追溯等域。在工廠或機器停機時保護工廠、工件和材料。主要用于爐子、半導(dǎo)體、船舶等域。無監(jiān)督和維修人員亦能保障正常運行。主要用于污水處理廠、隧道、船閘、樓宇系統(tǒng)等域。
3.效益
簡單、高效的工程組態(tài)與在標準系統(tǒng)中一樣，SIMATIC S7-400H 可以使用所有 STEP 7 編程語言進行編程?？梢院苋菀椎陌殉绦驈臉藴氏到y(tǒng)遷移到冗余系統(tǒng)中，反之亦然。當加載程序時，它會自動傳送到兩個冗余控制器中。使用 STEP 7，可以對特定冗余功能和配置進行參數(shù)設(shè)置。
4.出色的診斷和更換優(yōu)勢
利用集成的自我診斷功能，系統(tǒng)可以提前檢測故障和發(fā)送信號，避免故障對生產(chǎn)過程產(chǎn)生影響。這樣可以有針對性地替換故障組件，加快維修進程?？梢栽谙到y(tǒng)運行過程中對所有組件進行熱插拔。更換一個 CPU 后，當前的所有程序和數(shù)據(jù)可以自動重新裝載。即使在系統(tǒng)運行過程中，也可以修改程序（例如，程序塊的修改和重新裝載），更改配置（例如，增加或刪減 DP從站或）以及改變 CPU 的內(nèi)存分配。
