The IP address of the built-in Ether-
Net/IP port is also used as the IP
address of another node.
Perform either of the following and
then cycle the power supply to the
Controller or reset the Controller.
• Check the IP addresses of other
nodes and correct the IP address
settings so that the same address is
not used by more than one node.
• Remove the node that has the
duplicate IP address from the net-
work.
Perform allocations so that IP
addresses of nodes on the network
are used for only one node.
