■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 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.
No.0 (1 Gbps)

No.0: Master station
No.1, No.2, and No.3: Remote station
• When the communication speed for the master station is 1 Gbps, connection cannot be made if the total cyclic data size of
all device stations on the 100 Mbps device side, including the devices with a communication speed of 100 Mbps that form a
boundary between the communication speed of 1 Gbps and 100 Mbps, exceeds 2K bytes.
