3 Assigning Device Variables for CJ-series Units
3-18
CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
Information is stored for nodes 0 to 255.
This variable is a union, which allows access with different data types.
You can specify different data types to access the data: a BOOL array variable with 256 elements,
256 BOOL variables, or WORD variables.
This variable gives the registration status of the target nodes. It is valid only when the EtherNet/IP Unit
is the originator of the connection.
x.RegTargetSta.TargetSta [0] to [255]
x. RegTargetSta.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 gives the connection status of the target nodes. The elements of this variable change to
TRUE after all data for multiple connections for individual target devices is refreshed in the CPU Unit.
x.EstbTargetSta.TargetSta [0] to [255]
x. EstbTargetSta.TargetStaWd [0] to [15]
x: The name of the user-defined variable that is specified for the status area in the user settings.
