Duplicate IP Address
Detection
The adapter verifies that its IP address does not match any other device IP
address on the network when you perform either of these tasks:
• Connect the adapter to a EtherNet/IP network.
• Change the IP address on the adapter.
If the IP address matches that of another device on the network, the EtherNet/IP
port on the adapter transitions to conflict mode. In conflict mode, these
conditions exist:
• OK status indicator blinks red.
• Network (NET) status indicator is solid red.
• The following message scrolls across the 4-character display:
<IP_address_of_this_module> Duplicate IP -
<MAC_address_of_duplicate_node_detected>
For example: 10.88.60.196 Duplicate IP - 00:00:BC:02:34:B4
