操控體系簡介
s7-400是大型可編程序操控器，由電源模板(ps)、中央處理單元(cpu)、信號模板(sm)、通訊處理器(cp)等有些構(gòu)成。s7-400h體系是s7-400的冗余體系，經(jīng)過將發(fā)生中止的單元自動切換到備用單元的辦法完成體系的不中止作業(yè)。它能夠經(jīng)過本地機架與s7-400的i/o模件、通訊網(wǎng)關銜接，也能夠經(jīng)過根據(jù)profibus-dp總線的et200m分布式i/o與s7-300的i/o模塊、通訊網(wǎng)關銜接，以完成進程操控、與其它操控體系通訊。
3500機械保護體系是一個全功能監(jiān)測保護體系，其規(guī)劃應用了最新微處理器技能。由1塊或2塊電源模塊(3500/15)、框架接口模塊(3500/20)、溫度監(jiān)測器模塊(3500/60)、位移、速度、加速度監(jiān)測模塊(3500/42)、繼電器模塊(3500/32)、通訊網(wǎng)關(3500/92)等構(gòu)成。3500/92通訊網(wǎng)關是3500體系首要通訊通道，是與其它體系通訊的橋梁。
通訊計劃挑選
通訊完成的目標是將3500中的15個溫度點和6個壓縮機外殼振動點的值以及其報警、聯(lián)鎖狀況送到s7-400h，因為通訊的數(shù)據(jù)量不大，選用modbus rtu協(xié)議。
s7-400h與3500之間通訊首要有兩種方法：一是在s7-400h的本地機架上裝置一個cp(通訊處理器)。s7-400h有兩個冗余子體系，cp裝置在其中一個子體系上，兩個冗余的子體系都從該cp獲得數(shù)據(jù),并在兩個一樣的用戶程序中進行核算。因此，就冗余體系形式中的信息處理而論，cp是銜接到主cpu 仍是熱備cpu并無多大關系。缺陷是，當子體系呈現(xiàn)毛病時，該子體系機架上的cp不再可用。另一種方法是，將cp裝置在切換式i/o(et200m 分布式
i/o)上，該設備有一個有源板總線和一個冗余profibus-dp 從站接口模板im153-2，每個s7-400h子體系與et200m兩個dp從接口中的一個相連。這么，某個s7-400h冗余子體系毛病，cp會切換到它的冗余同伴，可靠性高，并且經(jīng)濟。咱們選用了該計劃，通訊處理器選用cp341。
