(3) Precautions
(a) Connecting devices to the same network
Do not connect Ethernet devices (e.g. personal computer) other than CC-Link IE Field Network devices to the
switching hub used by CC-Link IE Field Network. Doing so will cause timeout in the master station, resulting in
disconnection of all the stations.
(b) Configuration in which data link cannot be performed (incorrectly configured ring
topology)
Do not wire devices as shown below. Doing so will cause an error in all stations and data link cannot be performed.
• Connecting both PORT1 and PORT2 to the switching hub
• Ring topology through a switching hub
Ex.
