Owning Palette: Historical VIs
Requires: DSC Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Database Management VIs to create, delete, and rename Citadel databases.
Refer to the Measurement & Automation Explorer Help for Historical Data Viewer, available by selecting Help»Help Topics»Historical Data Viewer in Measurement & Automation Explorer, for more information about the Citadel databases.
The VIs on this palette can return general LabVIEW error codes or specific LabVIEW Datalogging and Supervisory Control (DSC) Module error codes.

|---|---|
| Alarm & Event Archive | Performs an archival operation for alarms and events on a Citadel database. |
| Archive Traces | Performs an archival operation on a Citadel database. |
