5.2.2
Network topology
It is typical of EtherNet/IP to have a rather free topology the limiting factor of which is large
message latencies due to e.g. switches connected in series.
The combination of a line and a stub is useful for system wiring.
EtherNet/IP supports the following topologies:
• Line
[5-4]
Line topology (S = scanner, A = adapter)
• Switch / star
[5-5]
Switch / star topology (SW = switch, A = adapter)
• Tree via switches
[5-6]
Tree topology (S = scanner, SW = switch)
