When Ethernet Cables Are Used - Mitsubishi Electric MELSEC iQ-R Series User Manual

When Ethernet cables are used

Network topology
For the Ethernet-equipped module, configure the network in star topology, line topology, or ring topology using the Ethernet
cables.
Star topology and line topology can be combined in a network. Ring topology cannot be combined with star or line topology.
■Star topology
The network is configured into a star shape using a switching hub and Ethernet cables. Normal stations can be easily added
to the network using this topology.
When an error occurs in a normal station, data link can be continued with the stations that are operating normally.
■Line topology
The network is configured into a line using Ethernet cables. A switching hub is not required.
When an error occurs in a normal station, the stations connected after the faulty station will be disconnected.
