彼此可进行数据交换的若干台设备的网络结构,被描述为一种拓扑结构。一个网络拓扑结构决定着其安全性:只有在部件之间的可替换/冗余连接情况下,当个别部件发生故障时,该系统的功能性才能作为一个整体,保持完好无损。物理拓扑结构描述了连接的结构,逻辑拓扑结构描述了连接内的数据流。Sercos Ⅲ支持哪些拓扑结构?通常情况下,所有Sercos?网络至少由一个主站和一个从站构成,主站负责协调,从站执行自动化功能。它们以简单、整齐的线型或环型拓扑结构排列。在此, The network structure of several devices that can exchange data with each other is described as a topology. A network topology determines its security: The functionality of a system as a whole remains intact only in the event of an individual component failure under alternative / redundant connections between components. The physical topology describes the structure of the connection, and the logical topology describes the data flow within the connection. Which topology does Sercos III support? Typically, all Sercos? Networks consist of at least one master and one slave, the master is responsible for coordinating and the slaves perform the automation. They are arranged in a simple, neat wire or ring topology. here,
