Continues.
Operation
The following operations will be performed depending on
the type of error in the non-volatile memory. (You can
check the error history in the EtherNet/IP Unit and the CIO
Area status.)
02 hex (network parameters): Tag data links stop.
06 hex (error history): The error history is not saved in
non-volatile memory.
09 hex (identity information): EtherNet/IP communications
stop.
0E hex (Unit name): No affect on other communications.
0F hex (basic Ethernet settings): Communications are not
possible.
10 hex (advanced Ethernet settings): The relevant func-
tion stops.
11 hex (MAC address): Ethernet communications stop.
12 hex (status area layout settings): Operation is per-
formed using default layout settings.
14 hex (Tag address resolve memory write error): Tag
data link communications stops.

Cause and
correction
Assumed cause
Correction
Prevention
There is a source of noise nearby.
If device parameter writing fails,
download the device parameters
using the Network Configurator.
Then, if the error persists even after
cycling the power supply or restarting
the EtherNet/IP Unit, check for ambi-
ent noise. If there is a noise source,
remove it.
Use the Unit away from sources of
noise. Implement noise countermea-
sures.
Non-volatile memory failure
If the error occurs even after perform-
ing the actions described above,
replace the EtherNet/IP Unit.
