NJ/NX-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
_EIP_TargetPLC-
ModeSta [255]
Target PLC Operat-
ing Mode
NX-series CPU Units: Shows the operat-
ing status of the target node Controllers
that are connected for CIP communica-
tions 1, with the built-in EtherNet/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 Oper-
ating 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.
NJ-series CPU Units: Shows the operat-
ing 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 Infor-
mation is TRUE. If the corresponding Nor-
mal Target Node Information is FALSE, the
Target Node Controller Operating Informa-
tion 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.

_EIP1_TargetPLC-
ModeSta [255]
CIP Communica-
tions1 Target PLC
Operating Mode
Shows the operating status of the target
node Controllers that are connected for
CIP communications 1, with the built-in
EtherNet/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 Oper-
ating 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.
Note You can use this system-defined vari-
able only for NX-series CPU Units.
