      • Can be used in combination with the “Data forwarding” function
    • LB60000 to LB6xxxx : Special internal system registers
  • LW Local Memory WORD Registers
    • LW0 to LW39999 : User/Project registers without backup
      • LW50000 to LW51993 : User/Project registers with backup in case of power failure
      • Can be used in combination with the “Data forwarding” function
    • LW59000 to LW59xxx : Special internal specific registers
    • LW60000 to LW6xxxx : Special internal system registers
  • RWI Local Memory WORD Registers for Formulas/Recipes
    • RWI0 : Display the Formula/Recipe specified by the Formula/Recipe number RWI0
    • RWI1 : Specify a Formula/Recipe number to display corresponding Formula/Recipe data in RWI

In macros (scripts), the keyword can be used directly in macro. It is not necessary to declare tags.

  • LocalBit[x]: reference of internal storage area LB
  • LocalWord[x]: reference of internal storage area LW
  • RWIWord[x]: reference of internal storage area RWI

For example: LocalBit[5], LocalWord[1]=0,..
