產(chǎn)品詳情
西門子S7-200針對(duì)低性能要求的摸塊化小控制系統(tǒng),它多可有7個(gè)模塊的擴(kuò)展能力,在模塊中集成背板總線,它的網(wǎng)絡(luò)聯(lián)接有rs-485通訊接口和profibus兩種,可通過(guò)編程器pg訪問(wèn)所有模塊,帶有電源、cpu和i/o的一體化單元設(shè)備。其中的擴(kuò)展模塊(em)有以下幾種:數(shù)字量輸入模塊(di)——24vdc和120/230vac;數(shù)字量輸出(do)——24vdc和繼電器;模擬量輸入模塊(ai)——電壓、電流、電阻和熱電偶;模擬量輸出模塊——電壓和電流。還有一個(gè)比較特殊的模塊-通訊處理器(cp)——該塊的功能是可以把s7-200作為主站連接到as-接口(傳感器和執(zhí)行器接口),通過(guò)as-接口的從站可以控制多達(dá)248個(gè)設(shè)備,這樣就可以顯著的擴(kuò)展s7-200的輸入和輸出點(diǎn)數(shù)。
西門子S7-300 中型可編程控制器
西門子S7-300相比較s7-200,s7-300針對(duì)的是中小系統(tǒng),他的模塊可以擴(kuò)展多達(dá)32個(gè)模塊,背板總線也在模塊內(nèi)集成,它的網(wǎng)絡(luò)連接已比較成熟和流行,有mpi、工業(yè)以太網(wǎng),使通訊和編程變得簡(jiǎn)單,選擇性也比較多,并可借助工具進(jìn)行組態(tài)和設(shè)置參數(shù)。s7-300的模塊稍微多一點(diǎn),除了信號(hào)模塊(sm)和200的em模塊同類型之外,它還有接口模塊(im)——用來(lái)進(jìn)行多層組態(tài),把總線從一層傳到另一層;占位模塊(dm)——為沒(méi)有設(shè)置參數(shù)的信號(hào)模塊保留一個(gè)插槽或?yàn)橐院蟀惭b的接口模塊保留一個(gè)插槽;功能模塊(fm)——執(zhí)行特殊功能,如計(jì)數(shù)、定位、閉環(huán)控制相當(dāng)于對(duì)cpu功能的一個(gè)擴(kuò)展或補(bǔ)充;通訊處理器(cp)——提供點(diǎn)對(duì)點(diǎn)連接、profibus和工業(yè)以太網(wǎng)。針對(duì)cpu設(shè)計(jì)模式選擇器有:mres=模塊復(fù)位功能;stop=停止模式,程序不執(zhí)行;run=程序執(zhí)行,編程器只讀操作;run-p=程序執(zhí)行,編程器可讀寫操作。狀態(tài)指示器:sf,batf=電池故障;dc5v=內(nèi)部5vdc電壓指示;frce=表示至少有一個(gè)輸入或輸出被強(qiáng)制;run=當(dāng)cpu啟動(dòng)時(shí)閃爍,在運(yùn)行模式下常亮;stop=在停止模式下常亮,有存儲(chǔ)器復(fù)位請(qǐng)求時(shí)慢速閃爍,正在執(zhí)行復(fù)位時(shí)快速閃爍。mpi接口用來(lái)連接到編程設(shè)備或其它設(shè)備,dp接口用來(lái)直接連接到分布式i/o。
西門子S7-400系列可編程控制器
西門子S7-400同300的區(qū)別主要在于熱啟動(dòng)(wrst)這一部分,其他基本一樣。它還有一個(gè)外部的電池電源接口,當(dāng)在線更換電池時(shí)可以向ram提供后備電源。編程設(shè)備主要有pg720pg740pg760——可以理解成裝有編程軟件的手提電腦;也可以直接用安裝有step7(siemens的編程軟件)的pc來(lái)完成。而實(shí)現(xiàn)通訊(要編程首先要和plc的cpu通訊上)的要求主要在于接口:1.可以在pc上裝cp5611卡——上面有mpi口,可用電纜直接連接。2.加個(gè)pc適配器,把mpi口轉(zhuǎn)換成rs-232口后接到pc上。3.plc加cp343卡,使它具有以太網(wǎng)口。
西門子S7-1200 小型可編程控制器
西門子SIMATIC S7-1200是一款緊湊型、模塊化的PLC,可完成簡(jiǎn)單邏輯控制、邏輯控制、HMI 和網(wǎng)絡(luò)通信等任務(wù) 。
