Query TDMS files to read measurement data.
What to Use
You can find the SystemLink TDM Reader and Configuration APIs on the Data
Communications palette in LabVIEW NXG 4.0 or later.
What
to Do
- On the client, create the following diagram in a VI to query TDMS
file.
Customize the gray sections for your unique programming
goals.
Troubleshooting
If you encounter errors, try the following
troubleshooting strategies:
- If you receive timeout errors, connection refused errors, or 404 errors,
verify the following things:
- The VI is connected to the correct server machine.
- The NI Web Server is configured, running on the server machine, and
accepts remote connections.
- The web service you want to use is installed on the server
machine.
- If Open Configuration (Auto) returns an error, verify
the application is on the server machine or a system managed by the
server.
- If you receive a 401 unauthorized errors, verify the credentials you specify
are correct and have sufficient permission specified in the NI Web
Server.

Note
Verify the permissions for each SystemLink API.
- If your application is a WebVI and you receive network errors, verify you
enabled CORS for web servers running on the same machine as clients in NI
Web Server.
- If you application is a WebVI and you want to deploy it, use Open
Configuration (Auto) and log into the web server before
accessing the WebVI.
