■Coexistence of line and star topologies
Line and star topologies can be mixed in the same network configuration.
• When the master station with a communication speed of 1 Gbps and a local or remote station with a communication speed
of 100 Mbps exist in the structure, set "Communication Period Setting" to "Low-Speed" for the local or remote station with a
communication speed of 100 Mbps.
No.0
Class B (1 Gbps)
No.0: Master station
No.1, No.2, No.3, No.4: Remote station
Class A: CC-Link IE TSN Class A device
Class B: CC-Link IE TSN Class B device
• If the communication speed of the master station is 1 Gbps, the total cyclic data size of all device stations on the 100 Mbps
device side at the boundary between communication speeds of 1 Gbps and 100 Mbps must not exceed 2K bytes.
