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

FINS/TCP

FINS/TCP Port

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

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

FINS/TCP Connection 
Setup

This is the network API used when TCP is used for the FINS com-
munications service. Up to 16 APIs can be used at a time, and they 
are identified by connection numbers 1 to 16.

The EtherNet/IP Unit or built-in EtherNet/IP port can thus simulta-
neously execute the FINS communications service by TCP with up 
to 16 remote nodes.

Protection Setting

Select this check box to refuse connection requests from any IP 
address not set as the target IP address when the server/client 
setting is set to a server and the target IP address is set to any 
value other than 0.0.0.0.

This check box can be selected to prevent inappropriate opera-
tions on the PLC for FINS commands from specific nodes.

FTP

Not Use FTP or

Use FTP

Specifies whether to use FTP. FTP connections from external 
devices will not be possible if Not Use FTP is specified. 

Login

Sets the login name for FTP connections to the  EtherNet/IP Unit 
or built-in EtherNet/IP port from external devices

Password

Sets the password for FTP connections to the  EtherNet/IP Unit or 
built-in EtherNet/IP port from external devices. 

Port No. 

Sets the FTP port number of the EtherNet/IP Unit or built-in 
EtherNet/IP port.

It is normally not necessary to change this setting. 

Two ports are used with the FTP: a control port and a data transfer 
port. Only the control port can be set. The data transfer port num-
ber will be one larger than the control port number.
