摘　　要：PLC组网是BAS系统的核心,研究BAS系统主要研究的是PLC如何组网的问题。目前市场应用较多的西门子、AB、施耐德品牌的中高端PLC,虽然分属不同品牌,但其组网方式却大同小异,且逐渐向以太网组网方式靠拢。从双总线方案、全光纤自愈以太环网方案、以太网+总线3种组网方式入手,分析了各种组网方式的优劣。总体来讲,以太网组网因其传输速率快、抗干扰性强、兼容性好等优点,是目前应用的主流方案。PLC networking is the core of BAS system,and the research of BAS system is mainly on how PLC networking.At present,the market application of more Siemens,AB,Schneider brand of high-end PLC,although they belong to different brands,but its networking method is much the same,and gradually to Ethernet network approach close.The advantages and disadvantages of various networking methods were analyzed starting with the dual bus scheme,the full fiber self-healing Ethernet network scheme,and the Ethernet-bus network.In general,Ethernet network is the mainstream scheme of the current application because of its fast transmission rate,strong anti-jamming,good compatibility and so on.
