A LabVIEW Datalogging and Supervisory Control (DSC) Module application typically consists of three components: front panels that you use to view and interact with data, shared variables that represent I/O data, and supervisory programs that implement custom I/O logic.

Note Some advanced DSC Module applications implement a fourth component, a system configuration management program, that programmatically configures the DSC Module application.

You can organize the components of a DSC Module application in a LabVIEW project.

The Shared Variable Engine (SVE) manages and provides access to shared variables. All DSC Module applications use both LabVIEW and the SVE.
