 Seven-segment Display
When the power is turned ON (or the Unit is restarted), all of the segments will flash twice, the IP
address set in the EtherNet/IP Unit will be displayed on the 7-segment display just once, from right
to left. Afterwards, the rightmost 8 bits of the IP address is displayed in hexadecimal during normal
operation.

The IP address is displayed in decimal, flowing from right to left.
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 Section 13 Troubleshooting.

If the Unit is operating normally, the last digit of the
Unit's IP address is displayed in hexadecimal.
