_EIP_TDLinkOpnErr Tag Data Link Con-
nection Failed
NX-series CPU Units: Indicates that
establishing a tag data link connection for
CIP communications 1 failed.
TRUE: Establishing a tag data link con-
nection failed due to one of the
following causes.
• The information registered for
a target node in the tag data
link parameters is different
from the actual node informa-
tion.
• There was no response from
the remote node.
FALSE: Other than the above.
NJ-series CPU Units: Indicates that estab-
lishing a tag data link connection failed.
TRUE: Establishing a tag data link con-
nection failed due to one of the
following causes.
• The information registered for
a target node in the tag data
link parameters is different
from the actual node informa-
tion.
• There was no response from
the remote node.
FALSE: Other than the above.
BOOL TRUE or
FALSE
