Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Data Logging

Module by: National Instruments. E-mail the author

Summary: In this lesson, you will learn how to store acquired data and average and log the acquired data to disk.

It is often necessary to permanently store data acquired from the DAQ device. Remember the following important considerations when planning to store data to a file.

  • Not all data logging applications use LabVIEW to process and analyze the stored data. Consider which applications will need to read the data.
  • The data storage format defines which applications can read the file. Since LabVIEW contains standard file operation functions that exist in other languages, the programmer has complete control over the data logging process.

LabVIEW includes the ability to create a LabVIEW measurement file, an ASCII text file that can be read by a spreadsheet, or a text editor. The LabVIEW measurement file is easy to create in LabVIEW, and easy to read in LabVIEW or other applications.

The Write LabVIEW Measurement File Express VI located on the Functions>>Output palette writes signals to a LabVIEW measurement file. When you place this Express VI on the block diagram, a configuration dialog box appears where you can specify how to store the file.

The Read LabVIEW Measurement File Express VI located on the Functions>>Input palette reads signals in a LabVIEW measurement file. This Express VI reads data one point at a time, so it is necessary to place this Express VI in a loop.
