3 Assigning Device Variables for CJ-series Units
3-8
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
These variables are used for inputs from the EtherNet/IP Unit to the CPU Unit.
This variable provides information on the target PLCs that are connected to the EtherNet/IP Unit when
the EtherNet/IP Unit is the originator.
Additional Information
• This status information is enabled when the Controller status is included in the communica-
tions data in both the originator and target node.
• This device variable for the CJ-series Unit provides information for only nodes 0 to 63.
• If it is necessary to get the error status of nodes higher than node 63, refer to 3-3 User Defini-
tion Settings for the Status Area.

Target Node PLC Operating Flags (EtherNet/IP Unit to CPU Unit)
(
*_TargetPLCMdSta [0] to [63] )
This variable provides information on the target PLCs that are connected to the EtherNet/IP Unit
when the EtherNet/IP Unit is the originator.
The information in this variable is valid only when the corresponding element in the Normal Target
Node Table is TRUE.
If the corresponding element in the Normal Target Node Table is FALSE, the Target Node PLC Oper-
ating Flags the previous operating status.

Target Node PLC Error Flags (EtherNet/IP Unit to CPU Unit)
(
*_TargetPLCErrSta [0] to [63] )
This variable indicates Controller errors (an OR of major faults, partial faults, and minor faults) in the
target PLCs that are connected to the EtherNet/IP Unit when the EtherNet/IP Unit is the originator.
The information in this variable is valid only when the corresponding element in the Normal Target
Node Table is TRUE.
If the corresponding element in the Normal Target Node Table is FALSE, the Target Node PLC Error
Flags retains the previous operating status.
