Message 2 of 4. Message 1 of 4. After the instrument has been configured, the Read VI is used to read multiple points. Many instrument drivers have a VI Tree VI you can use to view the entire instrument driver hierarchy. It must be a long bar of piezo material to resonate between 1 and Hz. Make sure that for each successful call to the Initialize VI, you use a matching Close VI to avoid maintaining unnecessary memory resources.

I’d give this a go and see how you get on Most Labbview Software Boards: If you are sure that you have selected the correct instrument and it is responding, try disabling the ID Query Error occurred at Agilent Action VIs are different from Configuration VIs because they do not change the instrument settings but order the instrument to carry out an action based on its current configuration.
Message 1 of This would explain your missing data. Message 9 of Then when I go to to run this driver, I see the next: The Initialize VI- the first instrument driver VI you call, establishes communication with the instrument. You can do this statically using the XY Graph’s Properties menu, or dynamically using property nodes.

Once the measurement is complete, the Close VI is called which performs an instrument error query and terminates the software connection to the instrument.
You commanded the Agilent to send data in binary block format: I need to know: Then the Configure Measurement VI is called to set the instrument up for the desired measurement.
Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. From the block diagram you can see that the instrument is first initialized with the Serial Configuration and VISA resource name specified on the front panel.

In this example, serial communication is used. Finally, the Simple Error Handler is called which indicates whether an error occurred.
What should I do if this is really the case?
I tried changing the timeout and bytes to read settings, but still nothing changes. Message 7 of Hi, It’s me again and I’m having trouble with data acquiring process with Labview instrument driver.
Last edited by a moderator: Thank you ben and Jamesnow the machines are working properly, and I can continue my work. That data is imbedded in the first few bytes. After you call these VIs, the instrument is ready to take measurements or to stimulate a system. Sep 2, 7. You may also be using a model that is not officially supported by this driver.

Message 4 of 4. Numerous Configuration VIs can exist, depending on the particular instrument. Message 2 of 4.
Sep 1, 2. The Configuration VIs- a collection of software routines that configure the instrument to perform the operation you want.
