Owning Palette: Engine Control 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 Libraries & Processes VIs to deploy or undeploy a LabVIEW project library; to create, delete, or enable a process; or to enable alarm or data logging on a process.

The VIs on this palette can return general LabVIEW error codes or specific DSC Module error codes.

Palette Object	Description
Create Process	Creates an empty process in the Shared Variable Engine on the host computer.
Delete Process	Removes a process and its associated variables from the Shared Variable Engine.
Deploy Libraries	Loads the variables in one or multiple LabVIEW project libraries into the Shared Variable Engine on the host computer. The variables are in a running state. Because this operation is available only on the host computer, any VIs contained in the project libraries remain unaffected.
Deploy Library	Loads the variables in a LabVIEW project library into the Shared Variable Engine on the host computer. The variables are in a running state. Because this operation is available only on the host computer, any VIs contained in the project library remain unaffected.
Enable Alarm Logging On Process	Enables and/or disables alarm logging for the process.
Enable Data Logging On Process	Enables and/or disables data logging for the process.
Enable Process	Toggles the run state of a process in the Shared Variable Engine.
Get Process List	Returns a list of all the processes defined in the Shared Variable Engine on the host computer without regard to the running state of the variable.
Get Process Log State	Returns the full name of the data and alarm databases that you configured for this process. This VI also returns whether you enabled logging for data or alarms.
Get Process Run State	Returns whether a process with the specified name exists in the Shared Variable Engine. If the process exists in the Shared Variable Engine, this VI returns the running state of the process.
Save to Library	Saves the deployed configuration of processes or shared variables to one or several LabVIEW project libraries.
Undeploy Library	Removes the variables defined in a LabVIEW project library from the Shared Variable Engine on the host computer.
