Cause and cor-
rection
Assumed cause Correction Prevention
The power supply to the target
node is OFF
.
Check the status of the target node
and start it up normally.
Check that the target node is oper-
ating properly and start the tag da-
ta link.
Communications with the target
node stopped.
CIP message communications
stopped at the target node or the
EtherNet/IP port.
Make the device start normal CIP
message communications.
Start CIP message communica-
tions successfully and then perform
tag data links.
The Ethernet cable connector for
EtherNet/IP is disconnected.
Check that the connector is fitted
correctly and reconnect the con-
nector
.
Connect the connector properly
.
The Ethernet cable for EtherNet/IP
is broken.
Replace the Ethernet cable. None
CIP communications are not al-
lowed by the firewall function or
Packet Filter function on the target
node or the devices on the com-
munication path.
Allow CIP communications in the
firewall function or Packet Filter
functions on the target node and
the devices on the communication
path.
Make sure that CIP communica-
tions are allowed in the firewall
function or Packet Filter functions
on the target node or the devices
on the communication path, and
then perform a tag data link.
An error occurred in the communi-
cations path.
Check the communications path
and take corrective measures if
there are any problems.
None

192.168.250.1)
Precautions/
Remarks
• This event des not occur for the following cases.
The Controller is connected as a target.
A connection timeout is occurring due to detection of a link OFF to an Ethernet switch.
• If errors occur for multiple connections in one node, the event log is registered only for one connection
where an error is occurring.
