Owning Palette: Historical VIs

Installed With: 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 Writing VIs to write data directly to the Citadel historical database without needing to configure and run a shared variable using the Shared Variable Engine. You can log data not automatically logged by the Shared Variable Engine or import data from an external data source to the Citadel database.

The VIs on this palette can return general LabVIEW error codes or specific LabVIEW Datalogging and Supervisory Control (DSC) Module error codes.

Palette Object	Description
Close Trace	Closes the Citadel trace specified by trace reference.
