Additional Information
Hierarchical Relationship of System-defined Variables Related to EtherNet/IP Errors in the
NJ-series CPU Unit
The system-defined variables that are related to EtherNet/IP errors have the following hierarchi-
cal relationship. For example, if the value of any of the _EIP_PortErr, _EIP_CipErr, or _EIP_Tc-
pAppErr variables in the second level is TRUE, then the _EIP_ErrSta variable in the first level
also changes to TRUE. Therefore, you can check the values of system-defined variables in a
higher level to see if an error has occurred for a variable in a lower level.
_EIP_DNSSrvErr DNS Server Connec-
tion Error
TRUE: The DNS client failed to connect to
the server (timeout).
FALSE: DNS is not enabled. Or, DNS is
enabled and the connection was
successful.
BOOL TRUE or
FALSE
