Refresh Modules VI

Owning Palette: NI Scan Engine VIs

Requires: Base Development System (Real-Time, Windows)

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.

These automatically-created I/O variables use the default I/O variable settings. This VI does not add the new I/O variables to a LabVIEW project, and the new I/O variables do not persist when the target restarts.

Refresh Modules Details

If you physically change an I/O module deployed from a LabVIEW project, this VI cannot overwrite the deployed configuration until you undeploy the I/O module in the LabVIEW project. However, if you physically change an I/O module that was automatically detected by this VI or the corresponding Refresh Local Modules button in the NI Distributed System Manager, this VI adds and deletes automatically-created I/O variables to match the new physical configuration.
