Countermeasure
Replace the Ether-
Net/IP Unit or (for a
built-in EtherNet/IP
port) the CPU Unit
if the error recurs
when the Unit is
restarted.
Set the node
address correctly
and restart the Eth-
erNet/IP Unit or
built-in EtherNet/IP
port.
Replace the CPU
Unit if the error
recurs when the
CPU Unit is
restarted.
Create the I/O
table.
Perform the simple
backup operation
again. If the error
recurs, replace the
Memory Card, or
EtherNet/IP Unit,
or (for a built-in
EtherNet/IP port)
the CPU Unit.
Check and correct
the CPU Unit's
operating environ-
ment.
