The control of several Instruments: read parameter and continuous dynamic update

Hello

I'm trying to control three instruments using LabVIEW. My DC power and generating function are connected to the computer with a GPIB/ENET 1000 while my scope is connected via the USB port. I am currently having the scope to take a reading for each iteration of the while loop and have the event handler if there are changes to the power settings. I went by respective examples of the instrument and came with the attached VI. I wondered for some time on an installation where you connect continuously and are able to modify settings dynamically; It's my first crack at it.

The idea is to expand this VI by logging the reads in a text file, by automating a sweep from 1 K - 1 MHz and taking averages of this sweep to chart in Excel. For now, I need to get down the basic and I'm constantly freezes when I run the VI. Sometimes it runs without problem, but begins to freeze when I try to set the DC supply voltage and other times it freezes right from the start. I wonder if it has to do with the placement of the read scope; before and after the handler but I can't test the theory now that I'm away from the laboratory.

Would appreciate any advice you can give,

Yusif Nurizade

Yusif,

Yes, the steps could be taken in a parallel loop. If this loop will be completely independent (don't share data or control with the other loop), it should be simple. If you do not need to pass data between the loops, you might well be better to learn the architecture of producer/consumer because youwould has essentially re - invent.

Jucheck.exe usually checks the Internet for the software updates available and invite you to install them to keep your updated program.

  • Firefox does not allow me to connect. It reads 'work' and continues to loop even if left for several hours. How can I fix it?

    Firefox has abandoned the synchronization for quite awhile and I finally had the time to try to re - sync all. When I did, I forgot my password and changed. Now, when I try to sign so that Firefox syncs, it reads "Work"... "and continues to do this even if left for several hours. I would like to have my bookmarks, etc. back. Help, please!

    Private browsing enabled or "never remember history" being selected would cause that in Firefox 50.0, but the 50.0.1 update was a fix for this problem.

  • Blu Ray player can not read the DVD. It can read CDs and Blu Ray discs, but not DVD.

    Recently, I lost my hard drive.  Dell sent me a new disk with the drivers that came with the computer.

    I just noticed that my Blu Ray player is no longer playing DVDs.  I don't know if the hard drive crash has nothing to do with it, or if it's a coincidence.

    Windows says I have the latest driver.

    The computer is a Dell XPS 8300.   Is the Blu Ray player: bd - re bh30n hl-dt-st.

    The player has not served almost at all.   I read that there are the eyes for the Blu Ray vs DVD, then maybe the DVD part has failed.

    I'm always suspect that miss me a piece of software or a changed value.

    Any ideas?

    For all of you, the poor souls who shared my problem on the internet, I got beyond that.   Even though all said I had the latest driver, I found someone who said that they had downloaded a newer driver form the LG site and it fixed the problem.   Well, BH30N wasn't a model # on the LG site, but I found here: http://www.firmwarehq.com/download_1703-file_BH30N-A103.zip.html Norton said it was OK, I clicked on the EXE file, he said that he had me upgrade from A101 to A103 and suggested that I reload.   Once I did, my Blu Ray player will read the DVD fine.

  • "Invalid column" on the place where several clauses with subqueries and cfqueryparam

    I see a behavior in the cfquery coldfusion I would like to find an exmplanation for.  I have a query that performs a subquery in the select part and if I have several where lines, I get a message 'invalid column name' to find out where my second article, but only when I'm with cfqueryparam

    For example, on what follows, I get "invalid column name «position_id»»

    SELECT department_staff_tbl.*,
    (SELECT max (bookmark_id)
    OF bookmarked_items_tbl
    WHERE item_id = department_staff_tbl.staff_id

    ) AS bookmark_id
    OF department_staff_tbl
    WHERE department_id = < cfqueryparam value = "" #arguments.deptid # "cfsqltype ="cf_sql_integer">"
    AND position_id = < cfqueryparam value = "" #arguments.posid # "cfsqltype ="cf_sql_integer">"
    AND staff_id = < cfqueryparam value = "" #arguments.staffid # "cfsqltype ="cf_sql_integer">"

    If I change the order of my where clause staff_id is first, and then he said "department_id" is an invalid column.

    If I don't have a where clause, it works.  (i.e. WHERE position_id = < cfqueryparam value = "" #arguments.posid # "cfsqltype =" cf_sql_integer">).

    If I remove the where clause of my subquery (WHERE item_id = department_staff_tbl.staff_id) it works.

    This also works if I remove the cfqueryparam where my article so that my query looks like this:

    SELECT department_staff_tbl.*,
    (SELECT max (bookmark_id)
    OF bookmarked_items_tbl
    WHERE item_id = department_staff_tbl.staff_id

    ) AS bookmark_id
    OF department_staff_tbl
    WHERE department_id = #arguments.deptid #.
    AND position_id = #arguments.posid #.
    AND staff_id = #arguments.staffid #.

    Any thoughts?

    A more conventional way to enter your data is without the subquery.  Something like that

    Select fields, the bookmarkid max (bookmark_id)

    from bookmarked_items__tbl join department_staff_tbl on staff_id = bookmark_id

    When etc.

  • What product Vmware is the best for several Windows Server 2003 and 2008 implementation

    Hi all

    I am just wondering that if I installed VMware on Windows Server 2003 Standard Edition and Windows Server 2003 Enterprize edition on VMware I was able to use more Ram installed, our server have 48GB of Ram but Server 2003 Standard allows only 4 GB max to use, to save money, I was wondering just if I can use the way I mentioned above.

    Looking at it, I think you have a misconception about the limitations of VMware, RAM and operating system. Your problem is that you see no more than 4 GB of RAM on your x 86 Server 2003 install? This is a limitation of the operating system - to use more RAM you need an operating system that can deal with the RAM.

    • If you install VMware Workstation on Windows Server 2003 standard x 86 edition then you will only be able to use the 4 GB of RAM, Windows Server 2003 Standard x 32 can process.

    • If you install VMware Workstation on Windows Server 2003 standard x 64 edition then you will be able to use the 32 GB of RAM that Windows Server 2003 Standard x 64 can process.

    • If you install VMware ESX, you can adjust your full 48GB of RAM and install multiple instances of Win 2003 Svr Standard, each of which can address 4 GB of your memory live available.

  • I'm trying to generate a table of random numbers 30. After each 5 readings a new vi must open and indicate to the user than 5 readings were made. and continue with the generation of the table again.

    because I don't have a sensor now, I am currently generating a table of random numbers 30. After each 5 readings a warning should be given to the user 5 readngs are completed. This cycle must be repeated. the size of the table is 30.

    Please help me, waiting for response as soon as possible.

    Once I have the transducer, I'll take 30 analog samples and then after each 5 smaples this wraning will be displayed din a new VI

    Use a while loop with a delay time representing your sampling interval.

    Use is equal to the count Terminal to see if 4, then 4th iteration = 5th sample.

    Use a box structure. The real deal will only run on the 4th iteration.

    In the case of true place a Subvi with your message of your choice in the front panel. Go to the properties of the VI window and set ' open the front panel when it is called.

    The condition to closing of attention is not given to your description.

    Consider that rather than usign a Subvi to do this, you can use the "dialog box one/two/three button" or "display message" live in the palette "user interface and dialogue."

    Please try it out and send your own VI. Do not provide us with a working solution.

    You can disable cookies by using the node property and ownership "Disabled". You can create a tab control and disable the entire tab control that will disable all inside of it.

    To do this programmatically, set up your code with a structure of the event and create an event when the user changes the value of a button or click the mouse.

    See the example I did:
