Commits the configured scan list and trigger settings to hardware and initiates the scan. If the niSwitch Commit VI was called earlier, niSwitch Initiate Scan only initiates the scan and returns immediately.

Once the scanning operation begins, you cannot perform any operations other than the niSwitch Abort Scan VI or the niSwitch Send Software Trigger VI, as well as retrieval of attributes. All other VIs return a Scan In Progress error.

To stop the scanning operation, call the niSwitch Abort Scan VI.
