Duplicate IP Address
Detection
When you change the IP address or connect the module to an EtherNet/IP
network, the module checks to make sure that the IP address assigned to this
module does not match the address of any other network device. If the module
determines that another device on the network with a matching IP address, the
EtherNet/IP port of the module goes into conflict mode where the Network
Status LED indicator is solid red.
To resolve this conflict, use the following instructions to change the IP address of
the module. Then, cycle power to the module or reset the modules by
disconnecting and then reconnecting the Ethernet cable.
Two modules could possibly detect a conflict simultaneously. If this occurs,
perform this procedure.
1.
Remove the module with the incorrect IP address and correct its conflict.
2.
Cycle power or disconnect the Ethernet cable from the second module and
reconnect it.
Behavior of Modules With Duplicate IP Addresses
Devices in conflict over an IP address behave differently depending on whether
connections have been established to either of the modules and whether both
modules support duplicate IP address detection.
