• When "Communication Mode" is set to "Multicast" and the communication speed of the master station is 1Gbps,
communication may not be possible depending on the type of the device if device stations with different communication
speeds of 1Gbps and 100Mbps coexist on the end side via the switching hub. 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 device station with 100Mbps.

■Coexistence of line and star topologies
Line and star topologies can be mixed in the same network configuration.
• Up to eight CC-Link IE TSN Class B devices including TSN hub can be connected from the master station to the end of
each network.
• When the master station with a communication speed of 1Gbps and a remote station with a communication speed of
100Mbps exist in the structure, set "Communication Period Setting" to "Low-Speed" for the remote station with a
communication speed of 100Mbps.
