Setting the Front Panel Switches
Setting the Unit Numbers
Set a unique unit number for the CJ2 CPU Unit built-in Ethernet/IP port. The same unit number
cannot be used by any other CPU Bus Unit connected to the CJ2 CPU Unit.
Use a small screwdriver to make the setting, and be sure not to damage the rotary switch. The unit
number is factory-set to 0.
Setting Node Numbers
Set a FINS address for the built-in Ethernet/IP port. With the FINS communications service, multiple
Ethernet/IP Units (including the CJ2 Unit built-in Ethernet/IP port) connected by Ethernet are
identified by their node addresses. Using the node address switches, set a unique node address in
hexadecimal. The same node address cannot be used by any other Ethernet/IP Unit or Ethernet
Unit connected on the same Ethernet network.
As long as it does not duplicate any other address, the node address can be set from 01 to FE (1 to
254 in decimal).
×16
Note The node address is factory-set to 01. With the default setting, the values set on these switches become the
last two digits of the built-in Ethernet/IP port's IP address.
The default IP address is 192.168.250.node_address. With the factory-set node address of 01, the
default IP address is 192.168.250.1.
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.
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 ISO 8877).
