Net/IP.
Note
(1) Always use a switching hub when using tag data links in the network.
(2) If a repeater hub is used for EtherNet/IP tag data links (cyclic communi-
cations), the network’s communications load will increase, data collisions
will occur frequently, and stable communications will be impossible.
