Hierarchical Relationship of System-defined Variables Related to EtherNet/IP Errors
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_TcpAppErr 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.
