How Can We Help?
HMI register types: LB, LW, RWI and retentive/save register
Types of HMI registers
The HMI has different registers for your project and for special use.
- LB Local Memory BIT Registers
- LB0 to LB39999 : User/Project registers without backup
- LB50000 to LB51999 : User/Project registers with backup in case of power failure
- Can be used in combination with the “Data forwarding” function
- LB60000 to LB6xxxx : Special internal system registers
- LB0 to LB39999 : User/Project registers without backup
- 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
- LW51994 to LW51999 reserved registers (do not use them)
- Can be used in combination with the “Data forwarding” function
- LW59000 to LW59xxx : Special internal specific registers
- LW60000 to LW6xxxx : Special internal system registers
- LW0 to LW39999 : User/Project registers without backup
- 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.
- LocalBit[x]: reference of internal storage area LB
- LocalWord[x]: reference of internal storage area LW (16 bits registers only)
- RWIWord[x]: reference of internal storage area RWI (16 bits registers only)
However, we recommend that you use the variable settings table, located under the macros/scripts editor.
