Registering Variables - Omron NA Series Practices Manual

３-４ Registering Variables
３-４-１ Variable Mapping Scheme
1. When an NJ exists within the same project in which an NA exists, all of the NJ's global
variables will be automatically reflected in the NA's variable mapping table.
2. You can select the variables required to create the pages of the NA series and register
them as the NA series' global variables. ("Create Device Variable")
Hardware
The function is called "variable mapping", and the names of the NA's global variables
allocated at this time are specified as "NJ controller name_NJ global variable name".
When NA is connected with NJ at 1: N, each NJ is identified by the controller name.

Precautions for Correct Use
If you change the variable type or other items of the NJ while variable mapping has
been already performed, a mapping error may occur because the change is
