Before you click Import, we recommend that you check that the variable addresses are calculated correctly - compare the numbers with the table of variable addresses in Tia Portal. As a rule, it is enough to check only the address of the last variable. If the addresses do not match, take screenshots of the address table in Tia Portal and send the screenshots along with the db file to technical support.
If an unsupported variable is found during import, it will be marked gray in the tree, and its import will be invalid.
