4 Determining IP Addresses

NJ-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
Additional Information
• The TCP/IP Settings Display is not updated even if the IP address is obtained normally from
the BOOTP server. To check the IP address that was obtained from the BOOTP server on the
TCP/IP Display, upload the project from the NJ-series Controller.
• If you cannot obtain the IP address from the BOOTP server, the
Fix at the IP address obtained
from BOOTP server Option is selected on the TCP/IP Display. Select Fixed Setting in the IP
Address Settings and manually set the IP address, subnet mask, and default gateway.
• If the Controller power supply is turned ON when the IP address was not normally obtained
from the BOOTP server, the setting remains at Fix at the IP address obtained from BOOTP
server
.
• After the IP address is obtained from the BOOTP server, the built-in EtherNet/IP port IP
address setting is automatically set to Fixed setting. Therefore, the IP address will not match
when the program is verified on the Sysmac Studio.
Additional Information
When the local IP address of the built-in EtherNet/IP is set, the FINS node address is automati-
cally set as follows:
Example: Pairing IP Addresses and FINS Node Addresses with Automatic Creation Method
The FINS node address is required for FINS communications (e.g., to connect to the CX-Integra-
tor and other Support Software).
Note You can use FINS message communications with NJ-series Controllers. However, not all memory areas in
the NJ-series CPU Unit can be accessed. If you require this functionality, e.g., to connect to existing sys-
tems, consult with your OMRON representative.
The same value as the host number is set.
Host number
(last 8 bits of the IP address)
After the IP address is obtained from the
BOOTP server, the node address of the
built-in EtherNet/IP FINS is set.

When FINS node address are created automati-
cally, the FINS node address is the host ID and it
cannot be changed. It can be changed if you use
both methods or an IP address table method.
