Palette ObjectDescription
Get Scan Engine ModeReturns the operating mode of the NI Scan Engine on the target.
Get Scan Engine PeriodReturns the scan period of the NI Scan Engine on the target.
Refresh ModulesDiscovers 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 ModeSets the operating mode of the NI Scan Engine on the target.
Set Scan Engine PeriodSets the scan period of the NI Scan Engine on the target.
Synchronize to Scan EngineSynchronizes 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.
