3-1-2 Built-in EtherNet/IP Section
For example, the display will change as follows if the IP address is 192.168.250.10:
If an error occurs, the error code will be displayed alternately with the rightmost byte of the affected
device’s IP address. For details on error codes, refer to 6-2-2 Checking Error Status at the Ether-
Net/IP Port Seven-segment Display.
The following examples show the displays for errors.
• A d6 error (failure to connect) has occurred in communications with IP address 192.168.250.8.
• A d6 error (failure to connect) has occurred in communications with IP address 192.168.250.9.
• A d5 error (verification error; target missing) has occurred in communications with IP address
192.168.250.40.
• A C6 error (multiple switches ON) and an EA error (EtherNet/IP expansion setting error) have
occurred at the built-in EtherNet/IP port.
: 0A
The IP address is displayed in decimal, flowing from right to left.
If the Unit is operating normally, the rightmost digits
of the Unit's IP address is displayed in hexadecimal.
Flashing: The tag data links are stopped.
Lit: The tag data links are operating.
( “0A” is the hexadecimal display
for the final row, 10, in the IP
address of the local Unit.)

Information on errors that occur in
communications with the target node,
along with the last digits of the Unit’ s IP
address, are displayed in hexadecimal.
