西門子PLC的網(wǎng)絡(luò)是適合不同的控制需要制定的,也為各個網(wǎng)絡(luò)層次之間提供了互連模塊或裝置,利用它們可以設(shè)計出滿足各種應(yīng)用需求的控制管理網(wǎng)絡(luò)。西門子S7系列PLC網(wǎng)絡(luò)采用3級總線復(fù)合型結(jié)構(gòu),zui底一級為遠程I/O鏈路,負責(zé)與現(xiàn)場設(shè)備通信,在遠程I/O鏈路中配置周期I/O通信機制。中間一級為Profibus現(xiàn)場總線或主從式多點鏈路。前者是一種新型現(xiàn)場總線,可承擔(dān)現(xiàn)場、控制、監(jiān)控三級的通信,采用令牌方式與主從輪詢相結(jié)合的存取控制方式;后者為一種主從式總線,采月主從輪詢式通信。zui高一層為工業(yè)以太網(wǎng),它負責(zé)傳送生產(chǎn)管理信息。在工業(yè)以太網(wǎng)通信協(xié)議的下層中配置以802.3為核心的以太網(wǎng)協(xié)議,在上層向用戶提供TF接口,實現(xiàn)AP協(xié)議與MMS協(xié)議。
PLC要提供金字塔功能或者說要實現(xiàn)NBS或ISO模型要求的功能,采用單層子網(wǎng)顯然是不行的。因為不同層所實現(xiàn)的功能不同,所承擔(dān)的任務(wù)的性質(zhì)不同,導(dǎo)致它們對通信的要求也就不一樣。在上層所傳送的主要是些生產(chǎn)管理信息,通信報文長,每次傳輸?shù)男畔⒘看?,要求通信的范圍也比較廣,但對通信實時性的要求卻不高。而在底層傳送的主要是些過程數(shù)據(jù)及控制命令,報文不長,每次通信量不大,通信距離也比較近,但對實時性及可靠性的要求卻比較高。中間層對通信的要求正好居于兩者之間。
PLC網(wǎng)絡(luò)的分級與生產(chǎn)金字塔的分層不是—一對應(yīng)的關(guān)系,相鄰幾層的功能,若對通信要求相近,則可合并,由一級子網(wǎng)去實現(xiàn)。采用多級復(fù)合結(jié)構(gòu)不僅使通信具有適應(yīng)性,而且具有良好的可擴展性,用戶可以根據(jù)投資情況及生產(chǎn)的發(fā)展,從單臺PLC到網(wǎng)絡(luò)、從底層向高層逐步擴展。下面列舉幾個有代表性公司的PLC網(wǎng)絡(luò)結(jié)構(gòu)。
