Each record in a datalog file must have the same data types associated . You can therefore use h5labview to read, create and modify such MAT files to exchange data with MATLAB!. 2. Note: This image is a LabVIEW snippet, which includes LabVIEW code that you can reuse in your project. The LabVIEW Application Examples are presented in the Video below: MATLAB uses the MAT file format to store data for import/export. Selects data from the table in the database identified by connection reference using the columns supplied in the columns array. For example, bytes (U8 and I8) and words (U16 and I16) can be treated as longs (I32). To download this example, click here. Use datalog files to access and manipulate data only in LabVIEW and to store complex data structures quickly and easily. Also, you will need to set-up your database connection (ODBC or whatever) on the new . This method is recommended because the user does not have to . . From the above example we can conclude that the waveform charts in LabView gives us point to point information about the data with respect to time, whereas, the graphs gives us the information about the data variation on a defined period of time. A datalog file stores data as a sequence of identically structured records, similar to a spreadsheet, where each row represents a record. Provides support for NI data acquisition and signal conditioning devices. This VI returns the data as a 2D array of variants. NI-VISA. Control Panel Administrative Tools Data Sources (ODBC) We will use this ODBC Connection later in LabVIEW in order to open the Database Connection from LabVIEW Theory Note! Execute your query. All LabVIEW data types are supported but not necessarily in their native form. Background: I've been using LabVIEW for a few years for automation testing tasks and until recently have been saving my data to "[DescriptorA]\[DescriptorB]\[test_info].csv" files.
