In every video I have seen about global data, is described how to create the global and how to handle it, but no one define what it is, where it phisically reside, who initilize it, what is its resilence and when is convinient to use it

Are the lines in a Data Block the same as "object attributes" in OO languages? Or is it just a sort of "folder" to put parts of your global variables and find them more easily when programming?

Siemens use 5BD numbers for one DB.
Our HMI Kinco can connect from Siemens only Data bases 1-10.
We have 4DB
DB 5, DB15, DB16 DB20
How we can set Nr from 1 to 10 for using 10DB in our HMI?😢😮😅😊❤❤❤
