TDMS File Viewer

TDMS File PropertiesFor LabVIEW-based test and measurement applications with demanding data storage requirements, DMC frequently uses the TDMS (Technical Data Management Streaming) file format. The TDMS format lends itself to development of cohesive test data management solutions, ensuring that data is stored in the most efficient, organized, and scalable fashion.

A more complete introduction to TDMS file usage in LabVIEW is given in this blog article: "LabVIEW Data Storage - Overview of TDMS"

Advantage of TDMS Files for Test Data Storage

When used properly, the TDMS data storage format provides several key benefits:

  • Inherent hierarchical organization: File > Group(s) > Channel(s)
  • Unlimited Group and Channel levels within a single file
  • Unlimited custom scalar properties stored at each level
  • Simplified high-speed streaming of data to file storage
  • Easy exchange between applications and platforms

Working with TDMS Files

TDMS Viewer Screen ShotThe National Instruments TDMS file format is an NI platform-supported file format. Most NI software development environments (LabVIEW, VeriStand, DIAdem, etc.) interface directly with TDMS files. Many third-party applications for engineering and scientific data analysis, simulation, and reporting are also quickly adding support for the TDMS file format.

Since many of the software products best suited to viewing and manipulating TDMS data are large and require proper licensing, not everyone in an organization will have access to them. Unfortunately, as with any complex file format, users without an application that supports reading TDMS files installed on their PC cannot open TDMS files.

If you find yourself with a TDMS file loaded with valuable data, but are stuck on a Windows PC without TDMS capable software, check out our TDMS file viewer. This application is a free utility we often hand out to customers using the TDMS file format as part of their test and measurement solution.

DMC's TDMS File Viewer is based on the simple example program provided with the LabVIEW Developer Environment, but includes a few added features to make its use a bit more user friendly. Additional functionality may be added by DMC as this utility matures, but if you have any special requests, let us know.

Download the TDMS File Viewer Installation (Zip file ~202MB)

If you already have the LabVIEW 2015 Run-time Engine, you can download just the DMC TDMS Viewer EXE (zip file, ~6MB). Copy all files in the zip file to a folder on your computer, and run the EXE from that folder.
