Variable name Meaning
_EIP_DNSSrvErr DNS Server Connec-
tion Error
*1 With the NJ-series CPU Unit, this variable can be used with the unit version 1.11 or later.
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.
