Linear Network Introduction
A linear network is a collection of devices that are daisy-chained together.

In this topology a communication issue in the media or device will prevent nodes
downstream from communicating.

The EtherNet/IP embedded switch technology allows this topology to be
implemented at the device level. No additional switches are required.
These are the primary advantages of a linear network:
• The network simplifies installation and reduces wiring and installation
costs.
• The network requires no special software configuration.
• Embedded switch products offer improved CIP Sync application
performance on linear networks.
The primary disadvantage of a linear network is that any break of the cable
disconnects all devices downstream from the break from the rest of the network.
