1.應(yīng)用
避免控制器故障引起的停機(jī)。主要用于生產(chǎn)、能源、供水系統(tǒng)、機(jī)場(chǎng)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(jī)器停機(jī)時(shí)保護(hù)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(yùn)行。主要用于污水處理廠、隧道、船閘、樓宇系統(tǒng)等域。
2.效益
與在標(biāo)準(zhǔn)系統(tǒng)中一樣，SIMATIC S7400H 可以使用所有 STEP 7 編程語言進(jìn)行編程。可以很容易的把程序從標(biāo)準(zhǔn)系統(tǒng)遷移到冗余系統(tǒng)中，反之亦然。當(dāng)加載程序時(shí)，它會(huì)自動(dòng)傳送到兩個(gè)冗余控制器中。使用 STEP 7，可以對(duì)特定冗余功能和配置進(jìn)行參數(shù)設(shè)置。出色的斷和更換優(yōu)勢(shì) 。 利用集成的自我診斷功能，系統(tǒng)可以提前檢測(cè)故障和發(fā)送信號(hào)，避免障對(duì)生產(chǎn)過程產(chǎn)生影響。這樣可以有針對(duì)性地替換故障組件，加快維修進(jìn)程?？梢栽谙到y(tǒng)運(yùn)行過程中對(duì)所有組件進(jìn)行熱插拔。更換一個(gè) CPU 后，當(dāng)前的所有程序和數(shù)據(jù)可以自動(dòng)重新裝載。即使在系統(tǒng)運(yùn)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。
3.設(shè)計(jì)和功能
根據(jù)統(tǒng)計(jì)數(shù)字表明，所有自動(dòng)化組件（無論是機(jī)械式、機(jī)電式，還是電子式）都會(huì)出現(xiàn)故障。因此，工廠維護(hù)和工廠改造也就必不缺少。在實(shí)際應(yīng)用中，期待的可用性是不現(xiàn)實(shí)的。通過西門子 SIMATIC S7400H，能夠較大限度地降低生產(chǎn)故障機(jī)率，較大化生產(chǎn)率。
