■Coexistence of line and star topologies
Line and star topologies can be mixed in the same network configuration.
• Configure the number of the CC-Link IE TSN Class B device stations and TSN switching hubs to eight or less in total on the
transmission path from the master station to the CC-Link IE TSN Class B device of the end.
• When the master station with a communication speed of 1 Gbps and a remote station with a communication speed of 100
Mbps exist in the structure, set "Communication Period Setting" to "Low-Speed" for the remote station with a
communication speed of 100 Mbps.

• When the communication speed of the master station is 1 Gbps, a connection cannot be established if the total cyclic data
size of all device stations on the 100 Mbps device side exceeds 2K bytes. This includes the devices with a communication
speed of 100 Mbps that form a boundary between the communication speed of 1 Gbps and 100 Mbps.
