Structure with modules on CC-Link IE TSN and Ethernet devices

Connection with modules on CC-Link IE TSN and Ethernet devices
■Line topology
The network with modules and devices is configured in a line topology. A general-purpose hub is not required.
Up to eight modules on CC-Link IE TSN can be connected to P1 or P2 of the master station at the position indicated with (1).
Connect Ethernet devices to the end of the network.

Class B
No.0: Master station
No.1: Local station (1st module)
No.8: Remote station (8th module)
(2) Ethernet device
Class A: Authentication Class A device
Class B: Authentication Class B device
When an error occurs in a slave station, the stations connected after the faulty station will be disconnected.
■Star topology
Modules or devices are connected in a star topology via a switching hub.
• Since cyclic data is sent to an Ethernet device when a local station is used with an Ethernet device on the end side via a
switching hub, communication may not be possible depending on the type of an Ethernet device.
