Specify the destination for acquired data
Description
LoggingMode can be set to Disk, Memory, or Disk&Memory. If LoggingMode is set to Disk, then acquired data (as well as device object and hardware information) is streamed to a disk file. If LoggingMode is set to Memory, then acquired data is stored in the data acquisition engine. If LoggingMode is set to Disk&Memory, then acquired data is stored in the data acquisition engine and is streamed to a disk file.
When logging to the engine, you must extract the data with the getdata function. If the data is not extracted, it might be overwritten.
When logging to disk, you can specify the log filename with the LogFileName property, and you can control the number of log files created with the LogToDiskMode property. You can return data stored in a disk file to the MATLAB workspace with the daqread function.
