3-3-4 Status Information Assigned to the User-defined Area
This variable gives the operating status of the target PLCs. It is valid only when the EtherNet/IP Unit is
the originator. The elements of this variable are valid only when the corresponding elements in the Nor-
mal Target Node Table is TRUE. If the corresponding element in Normal Target Node Table is FALSE,
the element in the Target Node PLC Operating Flags gives the previous operating status.
x.TargetPLCMdSta.TargetSta [0] to [255]
x. TargetPLCMdSta.TargetStaWd [0] to [15]
x: The name of the user-defined variable that is specified for the status area in the user settings.
This variable indicates Controller errors (an OR of major faults, partial faults, and minor faults) in the tar-
get PLCs.
The elements of this variable are valid only when the corresponding elements in the Normal Target
Node Table is TRUE. If the corresponding element in Normal Target Node Table is FALSE, the element
in the Target Node PLC Error Flags indicates the previous error status.
x.TargetPLCErrSta.TargetSta [0] to [255]
x. TargetPLCErrSta.TargetStaWd [0] to [15]
x: The name of the user-defined variable that is specified for the status area in the user settings.
