In addition to the tag data link parameters, the EtherNet/IP Unit and built-in
EtherNet/IP port also have the following communications and operation
parameters. 

• FINS/UDP

• FINS/TCP

• FTP

• Auto Adjust Time

• Status Area

• SNMP

• SNMP  Trap

These parameters are set as Unit Setup from the CX-Programmer. The
parameter settings are saved in flash memory in the EtherNet/IP Unit or CPU
Unit. (See note.)

Note The CPU Bus Unit Setup Area is not used for tag data link settings for an

EtherNet/IP Unit or built-in EtherNet/IP port. This point is different from the
operation of Ethernet Units.

When necessary, set the routing tables using the CX-Integrator.

FINS/UDP

FINS/UDP Port

Specifies the local UDP port number to use in the FINS communi-
cations service. The UDP uses the UDP port number to distinguish 
the application layer (FINS communications service in this case).

• Default value (9,600)
• User-set value (1 to 65,535)

Conversion

Selects one of the following methods to convert from the FINS 
node address to an IP address (FINS/UDP only).

• Automatic generation (dynamic setting)
• Automatic generation (static setting)
• IP address table
• Combined method

IP Address Table

Sets the IP address table that defines the relationship between 
FINS node addresses and IP addresses.

This table is effective only when FINS/UDP is being used and the 
IP address conversion method is set to the IP address table.

Dynamic change the tar-
get IP addresses

Selects dynamic change of other FINS/UDP nodes’ IP addresses. 
To disable dynamic changes, deselect this option by removing the 
check mark.
