01

Local node 
error

03

Local node send 
error

---

Lack of available space in 
internal buffers

The load (traffic) on the Ether-
net Unit is too heavy. Check 
your user applications.

05

Node address set-
ting error

Local IP 
address

The network cannot be 
used because the IP 
address setting is incor-
rect.

Correct the local IP address.

07

Local node busy 
(send failed)

System load

Lack of available space in 
internal buffers

The load (traffic) on the Ether-
net Unit is too heavy. Check 
your user applications.

02

Remote 
node error

01

Remote node not in 
network

IP address 
table and IP 
router table

IP address of remote 
node not set correctly.

Set IP address of remote 
node into IP address table 
and, if internetwork transmis-
sion is required, into the IP 
router table.

02

No Unit with speci-
fied unit address

Instruction’s 
control data

There is no Unit with the 
specified unit address.

Check the remote node's unit 
address.

05

Response timeout

Transfer condi-
tions

(Use FINS 
status read 
commands.)

Message packet was cor-
rupted by transmission 
error.

Increase the number of trans-
mit retry attempts.

Instruction’s 
control data

The response monitoring 
time is too short. 

Set a longer response moni-
toring time.

Read the error 
log.

The transmission frame 
may be corrupted or the 
internal reception buffer 
full.

Read out the error log and 
correct the system as 
required.

03

Unit error 
(Controller 
error)

01

Communications 
controller error

Affected con-
troller’s ERC 
indicator 

Error occurred in the 
communications control-
ler.

Take corrective action, refer-
ring to troubleshooting proce-
dures in this section.

02

PLC error

Affected 
node’s LED 
indicators

CPU Unit error occurred 
in the PLC at the remote 
node.

Clear the error in the CPU 
Unit. (Refer to the PLC's oper-
ation manuals.)

04

Unit number setting 
error

Unit number

The unit number setting 
is incorrect.

Confirm that the unit number 
set on the switch is within the

same unit number is not used 
twice in the same network.

04

Service not 
supported

01

Unsupported com-
mand

Command 
code

The specified command 
code is not supported by 
the destination Unit.

Check the command code.

FINS header 
frame length

A short frame (4 bytes) is 
being used for the FINS 
header frame.

The EtherNet/IP Unit does not 
support short headers.

05

01

Routing table setting 
error

Routing tables Remote node is not set in 

the routing tables.

Set the destination address in 
the routing tables.

02

Routing tables not 
registered

Routing tables Destination is unknown 

because there are no 
routing tables.

Set routing tables at the local

04

Too many relay 
points

Network con-
figuration

The maximum number of
