Item to check
Lack of available space in
internal buffers
The network cannot be
used because the IP
address setting is incor-
rect.
Lack of available space in
internal buffers
IP address of remote
node not set correctly.
There is no Unit with the
specified unit address.
Message packet was cor-
rupted by transmission
error.
The response monitoring
time is too short.
The transmission frame
may be corrupted or the
internal reception buffer
full.
Error occurred in the
communications control-
ler.
CPU Unit error occurred
in the PLC at the remote
node.
The unit number setting
is incorrect.
The specified command
code is not supported by
the destination Unit.
A short frame (4 bytes) is
being used for the FINS
header frame.
the routing tables.
because there are no
routing tables.
The maximum number of
network levels (3) was
exceeded in the com-
mand.
Likely cause
The load (traffic) on the Ether-
net Unit is too heavy. Check
your user applications.
Correct the local IP address.
The load (traffic) on the Ether-
net Unit is too heavy. Check
your user applications.
Set IP address of remote
node into IP address table
and, if internetwork transmis-
sion is required, into the IP
router table.
Check the remote node's unit
address.
Increase the number of trans-
mit retry attempts.
Set a longer response moni-
toring time.
Read out the error log and
correct the system as
required.
Take corrective action, refer-
ring to troubleshooting proce-
dures in this section.
Clear the error in the CPU
Unit. (Refer to the PLC's oper-
ation manuals.)
Confirm that the unit number
set on the switch is within the
specified range and that the
same unit number is not used
twice in the same network.
Check the command code.
The EtherNet/IP Unit does not
support short headers.
Set the destination address in
the routing tables.
Set routing tables at the local
node, remote node, and any
relay nodes.
Set the routing tables cor-
rectly.
Redesign the network, or
reconsider the routing tables
to reduce the number of relay
nodes in the command.
