Accessing Communication Areas Using Variables by NJ/NX Ser-
ies Controllers
In Controllers of the NJ series, I/O memory addresses assigned to each communication area can be
accessed from the user program only via variables.
Here is an example of using the input assembly and output assembly for that purpose.
For more detailed information about the data structure of each assembly, please refer to 3-1-7 Status
and Control Signals for Each Input and Output Assembly on page 3-14.
Access Using Network Variables
Customize and define variables based on the structure of each communication area of the smart cam-
era. Use Sysmac Studio to define the variables.
For operations of Sysmac Studio, refer to Sysmac Studio Version1 Operation manual (Cat. No.W504).
