About the Module Database

Each Data Archive includes a PI Module Database (MDB). The MDB stores information in a hierarchy that you can use to organize and classify resources according to your organization's needs. For example, you can store and view equipment type, office location, building names, and so on. You can also use the Module Database as a central registry for several PI applications' settings, including PI ICU.

Note: With PI Server 2010 and later, you cannot make changes to MDB unless it is synchronized with PI AF. See the MDB to AF Synchronization tool in PI SMT (Operation > MDB to AF Synchronization) for more information.
