Study Notes

File I/O Operations

A program that continuously runs a test and logs data to a file within an hour may require a consideration of "low-level" or "high-level" File I/O to achieve optimal performance.
If data is to be opened in Notepad, a suitable file format for storing data should be chosen.

DAQmx Functions and API

DAQmx is a programming interface that uses the "low-level" drivers, whereas VISA is a "high-level" API that calls these drivers.

SubVI and Terminal Errors

If unconnected terminals in a SubVI are not connected, they can cause an error.
To use a VI as a subVI, a new icon needs to be created.

Sequence Structure and State Machine

When using a sequence structure, it is possible to stop the execution of a program within any sequence.
Variables should be used in a VI whenever possible, in contrast to state machines, which serve a different purpose.

Program Development and Error Handling

Uncaught errors in a program can be detrimental to its execution, and hence, error handling mechanisms should be implemented.
State machines can be used to handle errors and exceptions in a program, providing a more robust development approach.

Description

Learn about the importance of test execution speed when continuously logging data into a file during an hour. Determine whether to use 'low-level' or 'high-level' File I/O VI-je for optimal performance.
