Connecting to a CJ-series Ethernet/IP Unit
Note 1 Always turn OFF the power to the PLC before setting the rotary switches.
2 Create I/O tables for the CPU Unit when setting the unit number for the first time or changing settings.
CJ-series EtherNet/IP Unit:

Setting the Front Panel Switches
Setting Unit Numbers
Always set the unit numbers so that the unit numbers of other CPU Bus Units mounted to the same
CPU Unit are all unique.
Use a small screwdriver to set the rotary switches, being careful not to damage them.
The factory setting is 0.
UNIT
No.
Setting Node Numbers
Use the node address switches to set the node address to a unique hexadecimal value. Do not set it
to the same value as any other Ethernet/IP Unit or built-in port on the same Ethernet/IP network. As
long as it does not duplicate the address of any other Ethernet/IP Unit or built-in port, the node
address can be set from 01 to FE hex (1 to 254 decimal).

×16
Set the upper digit using the left rotary switch and the lower digit using the right rotary switch.
The factory setting is 01. The Node ID of the dip switch here must be consistent with that of PLC in
the "Network Device Setting" dialog box for the actual project created in the NB-Designer.
Setting Local IP Addresses
Set the local IP address with the CX-Programmer or other computer support software. Refer to the
Ethernet/IP Unit Operation Manual (Cat. No. W465) for details on setting methods.
Ethernet Connectors
This is the connector used to connect the twisted-pair cable to the Ethernet.
• Electrical Characteristics: Conforms to IEEE802.3 standards.
• Connector Layout: RJ45 8-pin modular connector (conforms to ISO8877).
