Cause and cor-
rection
Assumed cause Correction Prevention
The tag data link connection infor-
mation is not the same for the origi-
nator and target.
Modify connection information of
the tag data link and download the
device parameter or connection
settings from Network Configurator
or Sysmac Studio.
Before starting the tag data link,
match the connection information
for the tag data link in the originator
and target.
Insufficient connections Please reduce class-3 messages. Please reduce the number of data
link and class-3 messages used.
CIP message communications at
the target node are stopped.
Make the device start normal CIP
message communications.
Start CIP message communica-
tions successfully and then perform
tag data links.
Setting to use tag data link com-
munications was made to the
NX-
series EtherNet/IP Unit that is in-
cluded in the CIP Safety connec-
tion settings.
Do not configure the
NX-series
EtherNet/IP Unit, which is included
in the CIP Safety connection set-
tings, to use tag data link commu-
nications.

The NX-series EtherNet/IP Unit
with tag data link communications
was added to the CIP Safety con-
nection settings.
Do not add the NX-series Ether-
Net/IP Unit, for which tag data link
