How Do I Install the TEDS Library into LabVIEW?

I need to install the TEDS Library for LabVIEW, but I am unsure on where to place the files it contains.
What are the steps to install this library?
How can I check if the library is already installed on my system?
I need to install the TEDS Library for LabVIEW in the cRIO.

The TEDS library gets installed with the compactRIO driver which you can download from this link: 
NI CompactRIO Download . You can easily check if the TEDS library and templates are installed on your system if you open the corresponding folders:
  • The TEDS-VIs can be found under C:\Program Files (x86)\National Instruments\LabVIEW 20xx\vi.lib\teds. There you should see two libraries: _teds_core.llb and TEDS_api.llb.
  • The templates can be found under C:\Program Files (x86)\National Instruments\Shared\Teds\Templates. In this folder you can find the two template files: IEEE_Legacy.tdl and NI_IEEE_Standard.tdl.
Note: If you install compactRIO 21.0 it will only install support for LabVIEW 64-bit. You can follow the instructions in the next section to install the files manually for LabVIEW 32-bit or if you are using a version older than 2018.

Install Library Manually
The file contains various .mnu,.tdl, and .llb files that you may not be sure where to store. The following instructions will step you through the process of getting the TEDS Library properly installed on your computer:
  1. Download the folder attached to this knowledge base and save it onto your desktop.
  2. Extract the contents of the folder. The newly extracted folder should now contain two folders, National Instruments and LabVIEW 7.1.
  3. If you are using a later version of LabVIEW, you must rename this folder to reflect the current version number so that the files are inserted properly into your current LabVIEW folder, i.e. rename the folder to LabVIEW 2017, if installing the TEDS Library into LabVIEW 2017.
  4. Locate the National Instruments directory on your computer, typically the National Instruments directory is created in C:\Program Files by default when you install LabVIEW or other NI software.
  5. Drag and drop the National Instruments folder from the into the above mentioned directory on your computer.
  6. A dialog window should appear, that administrator rights are required to access the Shared subfolder in the National Instruments folder. This will create the new path of directories in which the template files will be stored. This will not overwrite any of the folders or files that already existed in the original National Instruments folder. It will merely add to it.
  7. Now locate the folder that contains the original LabVIEW directory you are installing into. This is generally C:\Program Files\National Instruments.
  8. Drag and drop the LabVIEW folder you extracted from into the above mentioned location so the two folders will merge.
  9. Close LabVIEW if it is open, and relaunch it.


Install Library in a cRIO
  1. Follow the steps in this article to transfer files into a cRIO.
  2. Copy the files in the folder you preferred in the cRIO.
  3. Modify the File path in your LabVIEW code. 

After completion of the described steps the TEDS subpalette should appear on the Measurement I/O palette in the function palette of a LabVIEW block diagram.
