2-3 Selecting the Network Devices
2-3-1 Recommended Network Devices
The following table shows the devices recommended for use with the Ether-
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.
2-3-2 Network Devices Manufactured by OMRON
The following network devices are manufactured by OMRON for EtherNet/IP
networks.
2-3-3 Switching Hub Types
Unmanaged Layer 2 (L2)
Switching Hubs These switching hubs use the Ethernet MAC address to switch ports. Ordi-
nary switching hubs have this function. Switching hub functions and settings
cannot be changed.
Managed Layer 2 (L2)
Switching Hubs These switching hubs use the Ethernet address to switch ports. Switching hub
functions and settings can be changed using special software tools for switch-
ing hubs running on a network node. Analytical data can also be collected.
These switching hubs provide more-advanced functions that unmanaged
layer 2 switching hubs.
