In the configuration dialog box of the Write To Measurement File Express VI, click the Settings button to display this dialog box.
Use this dialog box to configure multiple files simultaneously.
This dialog box includes the following components:
Filename Suffix—Contains options for configuring the suffix to append to filenames.
Date and time—Appends the date and time to the filename to distinguish among multiple files.
Sequential numbers—Appends numbers in sequential order to the filename to distinguish among multiple files.
Pad with zeros—Pads numbers using zeros. This option is available only when you select Sequential numbers.
Width—Specifies the width to which you want to pad the number. This option is available only when you select Sequential numbers.
Both—Appends Date and time and Sequential numbers to the filename to distinguish among multiple files.
Filename preview—Displays a preview of the first filename in a series of multiple files. The suffix of the filename reflects the configuration you set in the Filename Suffix section of this dialog box.
Existing Files—Specifies the action to take if the file already exists.
Rename existing file—Renames the existing file.
Use next available filename—Uses the next available filename. For example, if test.lvm exists, LabVIEW saves the file as test1.lvm.
Overwrite file—Replaces data in an existing file.
File Termination—Specifies the condition for starting a new file. If the input data exceeds the File Termination settings, a new file will not be created until the next time the VI runs. You also can use the new_file input to create a new file when the new_file input is TRUE.
After n segments—Creates a new file when the file contains n segments of data.
Segments—Specifies the maximum number of segments the file can contain. If the number of segments in the file exceeds this value, LabVIEW creates a new file.
After n samples—Creates a new file when the file contains n samples of data.
Samples—Specifies the maximum number of samples the file can contain. If the number of samples in the file exceeds this value, LabVIEW creates a new file.
When file size exceeds limit—Creates a new file when the file exceeds a certain file size. This option is unavailable when you select the Microsoft Excel (.xlsx) option from the configuration dialog box of the Write To Measurement File Express VI.
KB—Specifies the maximum size of the file in kilobytes. If the file size exceeds this value, LabVIEW creates a new file.
At specified interval—Creates a new file at time intervals you specify.
Hours—Specifies the number of hours the file can gather data before creating a new file. When the number of hours exceeds this value and the number of minutes exceeds the value specified in Minutes, LabVIEW creates a new file.
Minutes—Specifies the number of minutes the file can gather data before creating a new file. When the number of minutes exceeds this value and the number of hours exceeds the value specified in Hours, LabVIEW creates a new file.
Daily at specified time—Creates a new file at the same time every day.
Time—Specifies the time you want LabVIEW to create a new file.
