3 System-defined Variables Related to the Built-in EtherNet/IP Port
3-16
NJ-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
Variable name _EIP_EstbTargetSta [255]
Meaning Normal Target Node Information Global/local Global
Function This variable gives a list of nodes that have normally established EtherNet/IP connections.
Array[x] is TRUE: The connection to the node with a target node ID of x was established normally.
Array[x] is FALSE: The connection to the node with a target node ID of x was not established, or an error
occurred.
Data type ARRAY [0..255] OF BOOL Range of values TRUE or FALSE
R/W access R Retained Not retained. Network Publish Published.
Usage in user program Possible. Related instruc-
tions

Variable name _EIP_TargetPLCModeSta [255]
Meaning Target PLC Operating Mode Global/local Global
Function This variable shows the operating status of the target node Controllers that are connected with the built-in Ether-
Net/IP port as the originator.
The array elements are valid only when the corresponding Normal Target Node Information is TRUE.
If the corresponding Normal Target Node Information is FALSE, the Target Node Controller Operating Information
indicates the previous operating status.
Array[x] is TRUE: This is the operating state of the target Controller with a node address of x.
Array[x] is FALSE: Other than the above.
Data type ARRAY [0..255] OF BOOL Range of values TRUE or FALSE
R/W access R Retained Not retained. Network Publish Published.
Usage in user program Possible. Related instruc-

Variable name _EIP_TargetPLCErr [255]
Meaning Target PLC Error Information Global/local Global
Function This variable shows the error status (logical OR of fatal and non-fatal errors) of the target node Controllers that
are connected with the built-in EtherNet/IP ports as the originator.
The array elements are valid only when the corresponding Normal Target Node Information is TRUE.
The immediately preceding value is retained if this variable is FALSE.
Array[x] is TRUE: A fatal or non-fatal error occurred in the target Controller with a target node ID of x.
Array[x] is FALSE: Other than the above.
Data type ARRAY [0..255] OF BOOL Range of values TRUE or FALSE
R/W access R Retained Not retained. Network Publish Published.
Usage in user program Possible. Related instruc-

Variable name _EIP_TargetNodeErr
Meaning Target Node Error Information Global/local Global
Function This variable indicates that the connection for the Registered Target Node Information was not established or that
an error occurred in the target Controller.
The array elements are valid only when the Registered Target Node Information is TRUE.
Array[x] is TRUE: A connection was not normally established with the target node for a target node ID of x (the
Registered Target Node Information is TRUE and the Normal Target Node Information is FALSE), or a connection
was established with the target node but an error occurred in the target Controller.
Array[x] is FALSE: The target node is not registered for a target node ID of x (the Registered Target Node Informa-
tion is FALSE), or a connection was normally established with the target node (the Registered Target Node Infor-
mation is TRUE and the Normal Target Node Information is TRUE). An error occurred in the target Controller (the
Target PLC Error Information is TRUE).
Data type ARRAY [0..255] OF BOOL Range of values TRUE or FALSE
