3 System-defined Variables Related to the Built-in EtherNet/IP Port
Hierarchical Relationship of System-defined Variables Related to EtherNet/IP Errors in the
NX-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 _EIP1_PortErr, _EIP2_PortErr, EIP1_Ci-
pErr, _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 val-
ues of system-defined variables in a higher level to see if an error has occurred for a variable in
a lower level.
Level 1
Variable
_EIP_ErrSta Built-in
Note You can access the same values of the system-defined variables whose variable names with _EIP1
and the system-defined variables whose variable names with _EIP. For example, you can access the
same values of _EIP1_PortErr (Communications Port1 Error) and _EIP_PortErr (Communcations
Port Error).
Note You can use the system-defined variables whose variable names start with _EIP2 only for the NX701
CPU Units and NX102 CPU Units.
