Variable name _EIP_TagAdrErr
Meaning Tag Name Resolution Error Global/local Global
Function NX-series CPU Units: Indicates that tag resolution for CIP communications 1 failed (i.e., the address could not be identi-
fied from the tag name).
TRUE: Tag resolution failed (i.e., the address could not be identified from the tag name). The following causes are
possible.
•The size of the network variable is different 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 vari-
able in the CPU Unit.
•There is no network variable in the CPU Unit that corresponds to the tag setting.
FALSE: Other than the above.
