3-56
NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
Variable name _EIP_TargetNodeErr [255]
Meaning Target Node Error Information Global/local Global
Function NX-series CPU Units: Indicates that the connection for the Registered Target Node Information for CIP communi-
cations 1 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 Regis-
tered 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).
NJ-series CPU Units: 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 Regis-
tered 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).

Variable name _EIP1_TargetNodeErr [255]
Meaning CIP Communications1 Target Node Error Infor-
mation
Global/local Global
Function Indicates that the connection for the Registered Target Node Information for CIP communications 1 was not estab-
lished 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 Regis-
tered 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).
Note You can use this system-defined variable only for NX-series CPU Units.
