The following sections include detailed information on the differences between the
new and previous PC products from SIMATIC NET

As of the SIMATIC NET PC software CD 07/2001, all SIMATIC NET PC software
products have central project engineering and download mechanisms. The project
engineering data is now stored in XDB configuration files. 

The previously used LDB databases can no longer be used.

Existing XDB databases can continue to be used after importing them into the
central data management of the PC station, the Station Configuration Editor.

Requirement for compatibility of the XDB file:

The XDB configuration file must be created with a version of STEP 7 V5.1 SP2 or
higher. As of this version, you will find a compatibility option in the configuration
dialog for the PC station. There, you must select “S/RTM is installed”.

The following graphics illustrate the new situation:

New, totally integrated and uniform project engineering within Advanced PC
Configuration with SIMATIC NCM PC V5.1 Service Pack 2/STEP 7 Version 5.1
Service Pack 2 or higher.

The local or remote project engineering data are downloaded using SIMATIC
NCM PC/STEP 7. It is also possible to transfer the project engineering data in
the form of an XDB database that is also created with the Station Configuration
Editor.

The OPC server and its protocol-specific adapters are optional elements and are
shown with broken lines.
