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

Connection with modules on CC-Link IE TSN and Ethernet devices
This section describes the system configurations when CC-Link IE TSN Class B devices and CC-Link IE TSN Class A devices
coexist, or when the system consists of modules with CC-Link IE TSN (master station, local stations, remote stations) of CC-
Link IE TSN Class A devices only and Ethernet devices.

Coexistence of line and star topologies
■Line topology
The network with modules and devices is configured in a line topology. A general-purpose hub is not required.
Up to eight CC-Link IE TSN Class B devices can be connected to the master station.
Connect Ethernet devices to the end of the network.

Class A: CC-Link IE TSN Class A device
Class B: CC-Link IE TSN 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 "Communication Mode" is set to "Multicast" and 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.
The communication will be enabled by configuring settings with the TSN hub so that the multicast frame (with
multicast MAC address 09:00:70:00:10:02 and 09:00:70:00:10:05) will not be transferred to the port of the
Ethernet device.
