# Access to DBs area in S7-1200/S7-1500

To access a DB in S7-1200/S7-1500 some additional setting PLC-side are needed:

* Only global DBs can be accessed
* The optimized block access must be turned off
* The access level must be “full” and the “connection mechanism” must allow GET/PUT

The setup of access to DBs in TIA Portal V15 is described below.

Right click on the DB and select *Properties...* item.
