New to Siemens PLC TIA Portal programming.

Is there a way in TIA Portal programming to move some boolean reference data entries from one DB to another and have the associated function block calls to the DB address update to the new DB address?

e.g. take some boolean entries from safety DB 10 and copy / paste their names into safety DB 22 then have the associated references in FC2 update to the new DB 22 address without having to go back into FC2 (and others) and update each cross reference address individually.

Hi Top_Hat.

You must tell on what CPU used in TIA portal because S7-1200 don't support STL language.

Maybe help for start:

How can you calculate an offset for an ANY pointer or change the pointer?
