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 switching hub is not required.
Up to eight CC-Link IE TSN Class B devices can be connected to each of P1 and P2 of the master station.

Class A: CC-Link IE TSN Class A device
Class B: CC-Link IE TSN Class B device
Connect Ethernet devices to the end of the network.
When an error occurs in a device 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 switching 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.
