Indicates that the tag resolution for CIP
communications 1 failed (i.e., the ad-
dress could not be identified from the tag

name). The following causes are possi-
ble.
• The size of the network variable is dif-
ferent from the tag settings.
• The I/O direction that is set in the tag
data link settings does not agree with
the I/O direction of the variable in the
NX-series EtherNet/IP Unit
.
• There is no network variable in the
NX-series EtherNet/IP Unit that corre-
sponds to the tag setting.
FALSE: Other than the above.
