What kind of tag should be used for portability purposes?

Tag scope determines visibility and persistence of data used by your logic. For portability, you want the data the program uses to travel with the program itself, not rely on outside definitions. Program-scoped tags are defined inside a specific program and are saved as part of that program. When you export or copy the program to another controller or project, those tags come along with it, keeping the logic self-contained and reducing dependencies on the controller or device-wide definitions. Global tags live at the controller level and may not exist or may have different values on another system, making porting fragile. Device-scoped tags tie data to a particular device or network, so moving the program to a different setup breaks those references. Memory-resident tags exist in memory and often depend on specific memory configurations, which can complicate portability. So, using program-scoped tags keeps the program self-contained and portable across different controllers and projects.
