Coexistence of line and star topologies
Line and star topologies can be mixed according to the availability of each connection.
• 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.
• Connect Ethernet devices at the end of line topology.
• When connecting an Ethernet device in a star topology, connect it with an industrial switch (for CC-Link IE TSN Class A) or
an industrial switch (for CC-Link IE TSN Class B).
