■Ring topology
The network is configured into a ring using Ethernet cables. A switching hub is not required.
When an error occurs in a slave station, data link can be continued with the stations that are operating normally.
For the RJ71EN71, ring topology is available only when "CC-Link IE Field" is selected as network type for P1 connector.
