西門子PLC的網絡是適合不同的控制需要制定的,也為各個網絡層次之間提供了互連模塊或裝置,利用它們可以設計出滿足各種應用需求的控制管理網絡。西門子S7系列PLC網絡采用3級總線復合型結構,zui底一級為遠程I/O鏈路,負責與現場設備通信,在遠程I/O鏈路中配置周期I/O通信機制。中間一級為Profibus現場總線或主從式多點鏈路。前者是一種新型現場總線,可承擔現場、控制、監控三級的通信,采用令牌方式與主從輪詢相結合的存取控制方式;后者為一種主從式總線,采月主從輪詢式通信。zui高一層為工業以太網,它負責傳送生產管理信息。在工業以太網通信協議的下層中配置以802.3為核心的以太網協議,在上層向用戶提供TF接口,實現AP協議與MMS協議。
PLC要提供金字塔功能或者說要實現NBS或ISO模型要求的功能,采用單層子網顯然是不行的。因為不同層所實現的功能不同,所承擔的任務的性質不同,導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管理信息,通信報文長,每次傳輸的信息量大,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據及控制命令,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網絡的分級與生產金字塔的分層不是—一對應的關系,相鄰幾層的功能,若對通信要求相近,則可合并,由一級子網去實現。采用多級復合結構不僅使通信具有適應性,而且具有良好的可擴展性,用戶可以根據投資情況及生產的發展,從單臺PLC到網絡、從底層向高層逐步擴展。下面列舉幾個有代表性公司的PLC網絡結構。
