Network Topology

The CC-Link IE TSN and CC-Link IE Field Network are configured using Ethernet cables.
CC-Link IE TSN
The connection on the CC-Link IE TSN side can be configured as follows.
• Line topology
• Ring topology
• Star topology (a switching hub is required)
• Mixture of line topology and star topology (a switching hub is required)
A ring topology can be used only when the CC-Link IE TSN Class setting of the master station is B.
If a ring topology is used with an NZ2GN-GFB module that has CC-Link IE TSN Class A, data link cannot be
performed.
CC-Link IE Field Network
The connection on the CC-Link IE Field Network side can be configured as follows.
• Line topology
• Star topology (a switching hub is required)
• Mixture of line topology and star topology (a switching hub is required)
• For a line topology, connection can only be made at the end of the network.
• CC-Link IE Field Network only has one port, so a ring topology cannot be used.
• The station number has no bearing on the order of cable connection. (It can be connected if it does not
follow the order of the station number.)
• Do not connect Ethernet devices to switching hubs that can handle 1Gbps used in the CC-Link IE Field
Network. Doing so may cause the CC-Link IE Field Network master station to time out due to switching hub
frame lag, and all stations to disconnect.
