Ethernet Units Operation Manual

Unit Components Section 3-3

Refer to 3-7 Creating an I/O Table.

8. For simple operation where the IP address only (and no other System Set-

up settings) is set, or for operation using the Programming Console only,

set the IP address in the allocated words in the DM Area using the CX-Pro-

grammer or Programming Console. (This method is mainly used when set-

ting the IP address in the allocated words in the DM Area using the

Programming Console only. When using this method, be sure to set the lo-

cal IP address value in the CPU Bus Unit System Setup to 00.00.00.00

(default). If a different value is set, the IP address set in the allocated words

in the DM Area will be overwritten with this value.)

Refer to 4-4 DM Area Allocations.

For operation with the System Setup set as desired, set the IP address in

the CPU Bus Unit System Setup with the CX-Programmer. This method is

used when setting the local IP address with the CX-Programmer. Any set

value other than 00.00.00.00 will be enabled as the local IP address.)

Refer to 4-2 CPU Bus Unit System Setup.

9. Create the routing tables using the CX-Net. (This step is required only if

FINS communications are used, or if CMND(490) is used by a PC with mul-

tiple Communications Units mounted to it.)

Refer to 3-8 Creating Routing Tables.

10. Make the settings in the System Setup using the CX-Programmer. (Create

the IP address table and IP router table.)

Refer to 3-9 System Setup, 3-10 Creating an IP Address Table, and 3-11

Creating an IP Router Table.

This step is required only in the following cases:

• When using a method other than automatic generation for IP address

conversion. (Address conversion method, IP address table.)

• When using the mail notification function.

• When setting a subnet mask.

• When setting an FTP login name and password.

• When Ethernet is configured in multiple segments. (IP router table)

• When Ethernet 4.28 is used (broadcast settings)

• When the UDP port number for FINS is changed to something other

than the default setting (9600).

11. Check communications. (Use PING command and an internode test.)
