Connecting the standard OpenSCADA libraries
The newly-created OpenSCADA project does not contain any specific configuration, in fact it is empty and provides for the user to create a new configuration in the local SQLite database file "St.db", which is located in its own directory of the project with the same name. It is easier to create a complex project of the SCADA system using libraries of functions of the API of the OpenSCADA object model and libraries of the graphical elements, as well as other OpenSCADA libraries. To use the OpenSCADA libraries you need database files where the libraries are stored: connect-add in the object of the database module "SQLite" (Fig.3.3.2.1), install-select the address and specify the database encoding in "UTF-8" (Fig.3.3.2.2). 
After what, or when there are already library database entries, you need to activate need ones, read on.
