本系統(tǒng)采用的PLC是德國SIEMENS公司生產(chǎn)的S7-200系列,主模塊采用CPU226,擴(kuò)展模塊采用數(shù)字量擴(kuò)展模塊EM222和模擬量擴(kuò)展模塊EM235。
S7-200系列CPU具有強(qiáng)大的通信能力。主要支持以下幾種協(xié)議:
1.PI(Point-to-Point)協(xié)議,即點(diǎn)到點(diǎn)接口協(xié)議。PPI是一個主/從協(xié)議,主站(其它CPU或SIMATIC編程器)給從站發(fā)送申請,從站進(jìn)行響應(yīng)。從站不初始化信息,只響應(yīng)主站的申請或查詢。如果在用戶程序中允許PPI主站模式,S7-200CPU在RUN模式下可以作為主站,還可以利用網(wǎng)絡(luò)讀(NETR)和網(wǎng)絡(luò)寫(NETW)指令讀寫其他CPU,同時也能夠作為從站響應(yīng)來自其它主站的申請。采用PPI協(xié)議的網(wǎng)絡(luò)中最多只能有32個主站。該協(xié)議主要是用來編程、PPI組網(wǎng)等
2.MPI(Multi-Point)協(xié)議,即多點(diǎn)接口協(xié)議。MPI可以是主/主協(xié)議或主/從協(xié)議,協(xié)議如何操作依賴于設(shè)備類型(設(shè)備是S7-200系列CPU時建立主/從連接)。MPI總在兩個相互通信的設(shè)備之間建立連接,其它主站不能干涉兩個設(shè)備之間已建立的連接。由于S7-200的連接是非公用的,并且需要CPU中的資源,每個S7-200CPU只能支持4個連接,每個EM277模塊支持6個連接。在使用時,每個S7-200CPU和EM277模塊保留兩個連接,分別用于連接SIMATIC編程器(或計算機(jī))以及操作面板。這些保留連接不能被其它類型的主站使用。
