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”) 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. Controller name: NJ_1 Controller name:
NJ_2 Controller name: NJ_3 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 19 Hardware Sysmac Studio Project NJ NA Program Page I/O Global Variable Global Map Variables Mapping Variables 1 2 1 2 Variable: NJ1 start _ _ Variable: NJ2 start _ _ Variable: NJ3 start _ _ Variable: start Variable: start Variable: start Variable: start Variable: start Variable: NJ3 start _ _
