Can a module SCXI 1102 with a block of 1303 b cause some channels of reading of the voltage signals and other signals of current reading at the same time?

Hello

I'm trying to use two sensors of moisture Omega HX85BA and experience two CFI mass flowmeters in current loop. Humidity sensors have three outputs 0 - 10V, while flow meters have two outputs 4-20 Ma. Can I have all four sensors to wire to the same block of connection SCXI-1303 and read all the signals in the same VI? the block is connected to an SCXI 1102 b card and a 6052E DAQ of NI PCI card.

Thanks in advance!

Hello BBalmforth,

Yes it can. Although you will need external resistances (I recommend resistors precision for better accuracy) for current signals. The SCXI 1102 b is indirectly measuring the current by measuring the voltage drop across the resistance. The table below describes the current diagram and how it will seek in LabVIEW and DAQ assistant.

  • [ADF, JDev 12.1.3] Fragment 3 sections (each with a grid + form): best solution to commit / rollback all changes at the same time?

    Hallo,

    I need to create a fragment like page2create.jsff in this picture http://digilander.libero.it/flattit82/OTN_FILES/TotalCommRoll.png

    You kindly could give me some advice on how to achieve the result shown in the picture?

    Could you a panel tabs help keep the 3 sections on the same page and making it simpler handling of commit / rollback as requested?

    Thank you

    Federico

    Hello

    Yes, you can use panelTabbed to create this type of layout and for the handling of commit or rollback

    1. If you want to commit and a rollback for all 3 tabs then place these buttons (Commit and Rollback) outside panelTabbed and allow the creation, update and deletion on all tabs at the same time, after completing the user operation can use commit or rollback for all tabs

    2. If you want to commit separate and operation of catering for the different tab, then create and modify mode disable other tabs except the active tab, and only after a commit or rollback in the current tab allow the user to navigate to the different tab

    Thank you

  • Why can't acquire data from strain and resistance at the same time with a NI 9219 module?

    Hello

    I use a chassis with a NI9219 module 9172 cDAQ to try to acquire the strain and resistance at the same time, with the Labview SignalExpress software.  Is this possible?  When I try to display two values of signal at the same time, I get an error of assistant DAQ 50103 'the specified resource is reserved.  The operation could not be performed as indicated.  I used to be able to acquire the strain and tension at the same time, but now even that gives me error 50103.  I have hours trying to figure this out.  Any help would be greatly appreciated.

    That's all!  Thank you very much, now I can sleep tonight - seriously!

  • Input module of data acquisition can be read by two or more LabVIEW vi at the same time % 3F

    I use the DAQ palette in LabVIEW to read the virtual channels of the input data acquisition module. I've done several VI who read many entries of three modules of simulations. The problem appears when I run two or more VI´s reading entries from the same virtual module (for example. first.VI module 1 input ai0 and second.VI bed ai0 entry module 1 bed), when this happens the next errors are shown:

    Error-50103

    Platform AND Services: The specified resource is reserved. The operation could not be performed as indicated.

    and

    Error-200022

    Resource requested by this task has already been reserved by another task.

    It's worrying because I want to get the DAQ chassis and some modules, but if this problem is present with physical equipment my application may be unnecessary. This means that entry module only can be read once at the time?

    I m using global variables in each Subvi to share data with main VI, however, I found the solution in a different way... I just changed to single channel and dbl sample playback mode, so I Don t need to clean up the task of reading in my subVI´s, the zeros isn´t problem here, and the six subVI´s work at the same time!

    Thanks for the tips!

  • In Acrobat XI, how can I select and move multiple blocks of text/image at the same time on the same page?

    I work with PDF files generated by student requiring all content in a specific range of margin. Occasional tables and figures are indented or otherwise properly spaced so that the content violates the margin requirement. In Acrobat X, I could use the selection tool to draw a selection rectangle around all text and lines of a table for example and just drag the entire table over a little to meet the requirements without referring the PDF to the author for correction. It did not always work, but quite often that I was able to use it on a daily basis.

    Is it possible to select several (but not ALL) blocks of text and image on a page pieces, so they may be submitted at the same time? If I have to select each text block and lines (or each point and in a chart) and move them each individually, it's going to be a nightmare.

    I have Acrobat XI for Mac and Windows, but tend to use the version of Windows more often.

    People have reported what happens when preview of the output (I think) window is open. So you can close.  have not heard of another fix

    Does anyone know if you can pair Bluetooth headset at the same time and heart rate monitor strap chest Bluetooth with the Apple Watch series 2? I can't find any info about it online. I hope so, because they have everything works without your phone now since it has GPS. Obviously a chest strap heart rate monitor gives you a more accurate reading. And who is running without music? If they want to really all the new capabilities of fitness improved series 2, that this is a must!

  • Mr President, how can I enter two rows at the same time with different default values that only the first line to use see?

    Mr President.

    My worm jdev is 12.2.1

    How to enter two rows at the same time with different default values that only the first line to use see?

    Suppose I have a table with four fields as below

    "DEBIT" VARCHAR2(7) , 
      "DRNAME" VARCHAR2(50),
      "CREDIT" VARCHAR2(7) , 
      "CRNAME" VARCHAR2(50),
    

    Now I want that when I click on a button (create an insert) to create the first line with the default values below

    firstrow.png

    So if I click on the button and then validate the second row with different values is also inserted on commit.

    The value of the second row are like the picture below

    tworows.png

    But the second row should be invisible. It could be achieved by adding vc in the vo.

    The difficult part in my question is therefore, to add the second row with the new default values.

    Because I already added default values in the first row.

    Now how to add second time default values.

  • Can I update several forms with the drop-even at the same time

    I have 20 + forms that have a menu drop-down together.  Each shape has between 1 and 15 cases of this drop-down list.  The values in the drop-down list are updated on a frequent basis.

    Currently I have an identical JavaScript Document named "UpdateDropdowns" in each shape.

    function update_dropdowns()

    {

    aList var = [' ', 'A', 'B', 'C' "];

    Add any other choice dropdown in the var aList in the specified format
    getField("TradeNameDropdown1").setItems (aList);

    getField("TradeNameDropdown2").setItems (aList);

    Add any other drop down menus added to the form in the specified format

        // Open Log Console (Ctrl-J), enter update_dropdowns()  (Ctrl-Enter)

    }

    There are more than 30 choices in my current iteration of unelistede var, but for brevity, I have listed only the 3 examples to illustrate my JavaScript.

    Currently when I update the drop-down list, I followed these steps

    1. Open form
    2. Open the Document UpdateDropdowns JavaScript
    3. Add the additional values
    4. Select and copy the var aList update
    5. Close the JavaScript Document
    6. Update the form in the Console log
    7. Repeat for all forms (collage in the new aList var to ensure compliance)

    Is it possible to update all my forms at the same time without having to go through this process of form with form?

    If you ask if you can run the software subscription on both machines at the same time, the answer is no.  Your license you can only use one of the facilities at any given time.

    If you ask that if you have the software installed and that can be used on both machines so the answer is Yes... just can not both machines in use, software subscription running at the same time.
