Importing Databases

Using Database Manager, you can import any database into memory. Importing a database merges it with the database currently in memory.

NOTE: Before you import a database, stop any I/O drivers or OPC servers you may have running.

Typically, you import a database when you want to:

• Change the scanning order of the blocks in the database.
• Combine two databases.

To change the scanning order of a database's blocks:

1. Export a database. For more information about exporting a database, refer to the section Exporting Databases.
2. Change the order in which the blocks are listed in the export file. For more information on a database's scanning order, refer to the section Changing a Database's Scanning Order.
3. In Classic view, on Database Manager's toolbar, click the New button.

In Ribbon view, click the Database Manager button, and then click New.

4. Import the edited export file.

This process ensures that only the original database resides in memory when Database Manager imports your database.

To combine two process databases:

1. Export each database.
2. Examine each export file. Verify that each block in each database has a unique name. If two blocks have the same name, change one. Remember to also change the text in the Next field of the previous block so that the chain remains intact.
3. Into an empty database, import one of the databases you want to merge.
4. Import the other database.

Import errors encountered by Database Manager are stored in the file IMPORT.ERR. This file resides in the Database path.
