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 hierarchical
relationship. For example, if the value of any of the _EIP1_PortErr, _EIP2_PortErr, EIP1_CipErr,
_EIP2_CipErr, and _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.
