NI Scan Engine VIs

June 2013, 372522F-01

Requires: Base Development System (Real-Time, Windows). This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the NI Scan Engine VIs to interface with the NI Scan Engine.

Palette Object	Description
Get Scan Engine Mode	Returns the operating mode of the NI Scan Engine on the target.
Get Scan Engine Period	Returns the scan period of the NI Scan Engine on the target.
Refresh Modules	Discovers new I/O modules on any local or networked target. If a local I/O module is detected in a slot that was not previously deployed from a LabVIEW project, this VI creates new I/O variables for the I/O module.
Set Scan Engine Mode	Sets the operating mode of the NI Scan Engine on the target.
Set Scan Engine Period	Sets the scan period of the NI Scan Engine on the target.
Synchronize to Scan Engine	Synchronizes execution timing to the scan period of the NI Scan Engine. This VI waits for each scan to complete and triggers subsequent code to execute once the scan engine has updated all values.

Subpalette	Description
Fault Configuration VIs	Use the Fault Configuration VIs to view and configure the level and triggering behavior of system faults.
Faults VIs	Use the Faults VIs to view, set, and clear NI Scan Engine faults programmatically. The VIs on this palette can return general LabVIEW error codes.
Forcing VIs	Use the Forcing VIs to force and unforce I/O variables programmatically. The VIs on this palette can return general LabVIEW error codes.
