DeltaV databases

DeltaV configuration data is stored in a database in one of the workstations in the system. This database is referred to as the persistent database. A system can have several databases, but only one database can be active within the system at a time.

A database includes everything you can see from the DeltaV Explorer. This includes:

• The library of control modules and function blocks included with the system
• The modules you create
• The workstations and controllers in the system (although they can all be viewed in Explorer, they might not all be physically connected to the network)
• System-wide data, such as named sets and alarm preferences

Displays are not stored in the database; however, the modules in the database reference the displays. Events are not part of the database. Each Event Chronicle is a separate database of events.
