Get data block layout #497

Hi, i'm building a program to transfer S7 Db to SQL (mysql / sqlite). It's done and it works.

It's possible to retrive the db data structure programmaticaly? (pointers and type data)

I need to create a flexible system, if technicien change a type of data or add any variable to db i need to rebuild the structure of communication and db.

I haven't saw anything on the doc for this.
