1-3-2 Devices Required for Constructing a Network
The basic configuration for a 100Base-TX Ethernet System consists of one
hub to which nodes are attached in star form using twisted-pair cable.
The devices shown in the following table are required to configure a network
with 100Base-TX-type CS1W-ETN21 and CJ1W-ETN21 Ethernet Units, so
prepare them in advance.
Recommended Hubs For details on recommended devices for constructing a network, refer to 2-4
Network Installation.
1-3-3 Setup Area and Related Peripheral Devices
Making Settings in the
CPU Bus Unit System
Setup Area (with the CX-
Programmer) For the Ethernet Unit to function as a node on an Ethernet network, make the
settings, as required, in the CPU Bus Unit System Setup Area allocated in
non-volatile memory in the CPU Unit.
Use the CX-Programmer to make the settings (by connecting online from the
I/O Table Window, selecting the Ethernet Unit, and then selecting Unit Setup).
Each time the Ethernet Unit is turned ON or restarted, it reads and uses the
contents of the CPU Bus Unit System Setup Area as the settings for the com-
munications services.

or CJ-series Ethernet
Units (CJ1W-ETN21)
These Ethernet Units are Communications Units that
connect a CS-series or CJ-series PLC to 100Base-TX
Ethernet networks. (They can also be used as 10Base-T.)
(2) Twisted-pair cable This is twisted-pair cable for connecting 100Base-TX-type
Ethernet Units to the hub, with an RJ45 Modular Connec-
tor at each end.
Use a category 3, 4, 5, or 5e UTP (unshielded twisted-
pair) or STP (shielded twisted-pair) cable.
(3) Hub This is a relay device for connecting multiple nodes in a
star LAN.
