5 SYSTEM CONFIGURATION
5.4 Structure of CC-Link IE TSN Class B/A Devices (CC-Link IE TSN Protocol Version 1.0 Only) and Ethernet Devices
Coexistence of line and star topologies
Line and star topologies can be mixed according to the availability of connection as described below.
• Configure the system with the number of CC-Link IE TSN Class B device stations and industrial switches (for CC-Link IE
TSN Class B) as eight or less in total for each port of the master station on the transmission path from the master station to
the CC-Link IE TSN Class B device of the end.
• When connecting CC-Link IE TSN Class A devices, they must be connected to the end side of a CC-Link IE TSN Class B
device or to an industrial switch (for CC-Link IE TSN Class B). In this case, the network can be configured in a star topology
with an industrial switch (for CC-Link IE TSN Class B) or an industrial switch (for CC-Link IE TSN Class A).
