Linear Network Topology
A linear network topology is a collection of devices that are daisy-chained
together across an EtherNet/IP network. Devices that can connect to a linear
network topology use embedded switch technology to remove any need for a
separate switch, as required in Star network topologies.
Figure 11
shows an example 1769-L18ERM-BB1B control system using a
linear network topology.
