IP Address 
Duplication

The IP address 
of the EtherNet/
IP Unit or built-in 
EtherNet/IP port 
is the same as 
the IP address 
set for another 
node.

• The Unit will be 

offline and unable to 
communicate. Errors 
will be returned to all 
communications 
requests.

• Data exchanges 

(refreshing) will con-
tinue with the CPU 
Unit.

The Unit Error 
Occurred Flag (n+10, 
bit 00), Network Error 
Occurred Flag (n+10, 
bit 01), and IP 
Address Duplication 
Error Flag (n+10, bit 
06) will go ON.

Check the IP 
addresses set on 
other nodes. 
Restart the Ether-
Net/IP Unit or built-
in EtherNet/IP port 
after correcting the 
IP address settings 
to eliminate dupli-
cations.
