CLAD File I/O & Data Management Flashcards

What LabVIEW data type is best suited for storing a fixed-size collection of mixed data types (e.g., a name and a temperature reading)?

Answer: Cluster

A Cluster groups multiple data elements of different types into a single structure, similar to a struct in text-based languages.

When saving LabVIEW measurement data that must be read back later with proper channel names and timestamps, which file format is most appropriate?

Answer: TDMS file

TDMS files natively store channel names, timestamps, properties, and raw data, making them ideal for structured measurement datasets.

What is the primary advantage of using LabVIEW's built-in 'Config File VIs' (configuration file functions)?

Answer: They read and write INI-style key-value configuration files in a standardized format

The Config File VIs provide a simple API for reading and writing INI-style configuration files, making application settings persistent without custom parsing.

In LabVIEW, which function converts a path data type to a string representation?

Answer: Path to String

The Path to String function converts a LabVIEW Path type to its string representation suitable for display or concatenation.

What does error checking at the file I/O level in LabVIEW typically involve?

Answer: Wiring error in/out terminals through each file function and checking error codes

LabVIEW's error handling convention passes error clusters through error in/out terminals on each function, propagating errors to a final handler.

Which LabVIEW function should you use to delete a file from disk?

Answer: Delete File

The Delete File function permanently removes a specified file or empty directory from the file system.
