When the power is turned ON (or the Unit is restarted), the IP address set in
the EtherNet/IP Unit is 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.
Example 1: Displaying IP Address 192.168.250.10
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 right-
most byte of the affected device's IP address. For details on error codes, refer
to ???Section 13 Error Processing and Maintenance.
