How Can I Access Data Stored by VI Logger?Primary Software: Other NI Software>>VI LoggerPrimary Software Version: 2.0 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I am using VI Logger to acquire data, and I want to access this data with another program for analysis and presentation. If I save the data acquired with VI Logger, how is this data saved and what are the best ways to access it? Solution: Data stored by VI Logger is stored as a binary file to conserve space. This file format is optimized for VI Logger. Often it is desirable to access this data with another program such as LabVIEW to perform advanced analysis. You have several different options for accessing the data: Exporting to a Text File One option to access data is to use the tools within VI Logger to export this data to a text file such as a Comma Separated Value (CSV) file. To Export data from VI Logger, create a task and log data. Once the data log is available in Measurement and Automation Explorer (MAX), highlight this data log and select Export Data. The following screen appears and allows the you to configure information about the exported file.
Use the Field Delimiter to select the delimiter for the text file. Comma separated files are common. Use the Advanced setting to select information from VI Logger that will be included in the exported file. Saving Task Data to File with LabVIEW With the built-in VI Logger VIs for LabVIEW, the transition from a VI Logger acquisition to LabVIEW is easy and useful for creating more powerful programs. The VI Logger palette that installs with VI Logger, offers several VIs for automating tasks and accessing logged data. Note: LabVIEW must be installed correctly before VI Logger will install the correct VIs for LabVIEW. Refer to the Installation instructions or KnowledgeBase 30S7QFBS linked below for the correct installation process.
VI Logger saves data logged from a Task in C:\Program Files\National Instruments\VI Logger\data by default. Related Links: KnowledgeBase 30S7QFBS.
