  If an error occurred in the Unit's non-volatile memory itself, download the Unit Setup from the tab pages of the Edit Parameters Dialog Box of the CX-Programmer and download the device parameters from the Network Configurator. If the error recurs, replace the EtherNet/IP Unit or (for a built-in EtherNet/IP port) the CPU Unit.
