After the IP address settings are downloaded, the IP address is reflected in the CPU Unit as fol-
lows:
Setting a User-specified IP Address
After the IP address settings are downloaded, the set IP address is automatically saved in the
CPU Unit.
Obtaining the IP Address from the BOOTP Server Each Time the Power Is Turned ON
After the data is downloaded, the IP address from the BOOTP server is automatically saved in
the CPU Unit. Each time the power supply is turned ON, the IP address from the BOOTP server
is automatically saved in the CPU Unit.
Additional Information
If you cannot obtain the IP address from the BOOTP server or the obtained IP address is not cor-
rect, select the Fixed setting Option in the IP Address Area and manually set the IP address,
subnet mask, and default gateway. Requests to the BOOTP server to obtain the IP address will
continue if there is a failure to connect to the BOOTP server.
Obtaining the IP Address from the BOOTP Server Once When the Power Is Turned ON
and Then Not Allow It to Change
After the I/O address is downloaded, the IP address from the BOOTP server is automatically
saved in the Controller and then the same address is used.
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/NX-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.
