Replacing the module involves removing the old module and mounting a new one in its place.
You can replace the EtherNet/IP communication module at any time using another module with compatible firmware. A communication module can be replaced when power to the module is either:
-
off (cold swap), or
-
on (hot swap)
The replacement module obtains its IP address and operating parameters over the backplane connection from the CPU. The transfer occurs either immediately (hot swap) or when power is next cycled to the device (cold swap).
NOTE: The operating parameters the CPU sends to a replacement module do not include any parameter values that were edited in the original module using explicit messaging "SET" commands. Explicit messaging can be performed in the Online Action window of the Control Expert EtherNet/IP configuration tool.
