10 Questions
Program koji obavlja nekakav test se kontinuirano izvrsava i logira podatke o testu u jednu datoteku tijekom jednog sata. Ako je bitna brzina izvrsavanja testa, da li se treba koristiti "low-level" ili "high-level" File I/O VI-je?
"Low-Level"
Ako podatke iz datoteke zelite otvoriti u "Notepad-u" koji format datoteke za pohranu podataka treba koristiti?
ASCII

create task-configure task-start task-acquire/generate data-clear task
VISA je "high level" API koji poziva "low-level" drivere
True
pridruzi
G = C,C++, Java, BASIC, itd. Block Dijagram = Programski kod Front panel = Korisnicko sučelje SubVI = podprogram
Koji terminali su SubVI-u, ako nisu spojeni, uzrokuju pogrešku?
Required

False
kada se koristi sequence struktura moguce je zaustaviti izvrsenje programa unutar bilo koje sekvence
False

sve od navedenog
varijable treba koristiti u VI-u kad god je to moguce
False
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.
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.
