Devices Required to Construct a Network

The basic configuration for an EtherNet/IP system includes one Ethernet switch to which nodes are
attached in star configuration using twisted-pair cable.
Sysmac Studio
(Support Software)
Ethernet (LAN) port
The following products are also required to build a network. Obtain them in advance.

Precautions for Correct Use Precautions for Correct Use
• You cannot place the Sysmac Studio online with an NJ-series CPU Unit if you connect through
an EtherNet/IP Unit.
• You cannot perform troubleshooting from an NS-series PT if you connect an NS-series PT to
the Controller through an EtherNet/IP Unit.

Function
These Units are used to connect to an EtherNet/IP net-
work.
The twisted-pair cable has a RJ45 Modular Connector
at each end. This cable is used to connect the built-in
EtherNet/IP port or EtherNet/IP Unit to an Ethernet
switch. Use an STP (shielded twisted-pair) cable of cat-
egory 5, 5e, or higher.
This is a relay device that connects multiple nodes in a
star LAN. For details on recommended devices to con-
figure a network, refer to 2-3-1 Recommended Network
Devices.
