Why did the counter works in MAX, but not of Labview?

Please help, I've been away from Labview for more than 3 months and I'm pretty rusty...

Last year, I configured successfully NI9401 to measure the period (in seconds) by counting the rising edges of my sensor signal.  Since then, I bought a new PC and loaded all my software inside, including the Labview VI that has worked successfully on the old computer.

I can see the digital signal using MAX and test for the NI9401 Panel, then, I know that my son and my TTL signal is OK, but nothing except the below error when I try to run the attached VI, happens...  How can I say this VI to search for the signal on channel 14 and MOD3/CTR0?

Thank you. I'm sure it's a small adjustment... it worked well a few months ago... do not know what the problem is now.

Thank you

Dave

OK, now.  Solved the problem. The vi is fine, but some fragile son have been identified... worked in MAX but not in vi.  Now that the connections have been tightened, it works for both.  Sorry for the inconvenience.

  • Why my website slider works in Chrome, but not in Internet Explorer

    Why my website slider works in Chrome, but not in Internet Explorer

    On this page it says IE version 10 uses "animation".

    & then if you look at the examples on this page it shows:

    div {}

    -webkit-animation: myfirst 5 s; / * Chrome, Safari, opera * /.

    Animation: myfirst 5 s;

    }

    So, you will need to do.

    Also, check the CSS3 menu on the left, there "transform 2D" then you should find how to join also CSS3 2D transforms

    I have never used myself these animation properties, but these pages will have the info you need.

  • Camera works to the MAX, but not in LabVIEW

    I struggled a lot with getting a camera DCC3240M of Thorlabs working in LabVIEW. The software supplied (Thorcam) works as it should. However, the LabVIEW SDK does not work as it should, it gives an error 155 "the operation is not supported.

    Instead of the SDK software, I tried the drivers for DirectShow and now the camera arrives in MAX and works as it should. He also appears with IMAQdx list Cameras.vi and in Vision Acquisition Express vi. BUT when I try to run IMAQdx open Camera.vi or the Express vi it does not work. Open device gives a DirectShow error code 0 x 80040275 "no capture hardware is available, or the hardware is not responding." And when I try to select the camera in the express vi, a red icon is displayed and I can only choose "Cancel":

    It's really very annoying that the camera obviously work with the drivers provided, but I can't use it in LabVIEW.

    I would be grateful for any ideas what is wrong. I'm running LabVIEW 32 bit on 64 bit Win8.1.

    Problem solved!

    I carefully removed all the drivers that came with the camera and then I installed the drivers from manufacturers (IDS) instead of Thorlabs drivers. And now it works, the camera always appears in MAX and it does not work. But now the supplied screw. I'm so happy. It took me a week to understand.

  • FireWire camera works to the MAX, but not in LabView

    Hello

    I use a 1394b (grey Grasshopper Point 14S5M-C) camera connected to a 1394 bus controller. In MAX, the camera works fine, but it will not work with all files of 1394-example LabView. These allways throw the error "NOR-IMAQ IEEE-1394: (Hex 0xBFF6800F) attribute not supported by the camera" even if some of these example like "grab.vi" files no attributes are defined at all. On the same computer, another device (Point Grey Scorpion 20SOM, 1394 (a) works without any problem.

    Can anyone help?

    Hi Christian,

    Thanks for this tip, this is the reason. I was unintentionally using the IMAQ instead of example IMAQdx files. With IMAQdx it works now.

    Best regards

  • communication serial port works to the max, but not in labview

    Hello

    I am trying to connect a regulator to oxygen flow (flow Bronkhorst EL) to a laptop through a USB using MAX and Labview series port adapter. After the MAX aperture, I see my instrument on port COM5 and need to change the baud rate to 9600 to 38400. After this I querry the command: 06030101217D00\r\n, I can turn the mass flow at maximum power regulator (looks a little weird order because of the syntax of the instrument, but it works very well). If I write a vi to do the same and send the same string through visa series, I get no results, it seems that the command is not send to the device. I tried to change all settings for the serial port, nothing seems to work.

    I've attached an example vi here, any suggestions?

    Hello

    just a simple misunderstanding, happy that you added the code.

    In MAX \r\n will be always interpreted as send a cr and line break.

    In LabVIEW only when you select \codes view by right-clicking on the channel.

    In your situation, it now sends a-a r another- and a n

  • Reading to the MAX but not of LabVIEW

    Hello

    I have a very difficult problem to read four counters of a NI 9401. In MAX, they read very well but in LabVIEW, they read zero. I scoured the internet and discussion boards and can't find anything on it. Please forgive me if this is a simple thing to fix. IM attaching two png which shows where I read meters and a picture of my task. I know that the VI everything would work better but I'm not posting my project as a whole.  I fixed it where some of the forum posts I found said have it better. Any help would be great. If you need a certain thing just let me know.

    Kind regards

  • the link works in jsf, but not in jsff

    Hello.

    I use jdev 12.1.3.

    I have an application that will provide a jsf, an input file, a button and a code in a method to download and save the file in a scope of request bean. And it works very well...

    <af:button text="button 1" id="b1" action="#{requestScope.uploadBean.uploading}"/>

    Of the same application, I have an exact copy of this configuration in a JSFF calling the bean in scope request even. The jsff is placed in a dynamic region in a jsf which has 2 dynamic regions in 2 panel tabs... and if gives me a nullPointerException. Unattainable goal, 'null' returned null with the binding also works very well in the Joint Strike Fighter

    <af:button text="button 1" id="b1" action="#{requestScope.uploadBean.uploading}"/>

    Anyone have any idea why I'm down on this behavior?

    Kind regards.

  • Target visible FPGA in MAX but not in LabVIEW

    Hey!

    I recently installed a RIO device. Before installing the equipment, I installed the module FPGA & RIO 3.0 as directed. Now, I can see the device in a position & automation explorer, but its not in list "Add target & devices. It says "No device found" in the existing devices tab. I don't understand the problem. :/

  • What should I do when I can communicate with my instrument NI MAX through other programs, but not of LabVIEW?

    Hi all, this is a question that I had a few times before in one form or another.

    I use a Boxcar Integrator (245 SRS is the interface) for my experience. I connect to it via GPIB using my Agilent GPIB/USB interface. My program runs in LabVIEW, and I used it successfully in the (very recent) past.

    However, sometimes if I get LabVIEW or something, some weird stuff starts past trying to connect to it. For example, after the LV exit and go back to the top and any attempt to run my program, it throws the error:

    Error 1073807339 has occurred in the CITATION read in OR_Boxcar_ReadAnalogPort3.vi-> OR_Boxcar_SimpleTest.vi

    Possible reasons:

    VISA: (Hex 0xBFFF0015) timeout expired before the operation is complete.

    Which essentially means that he cannot connect for some reason or another (don't worry, I'm on the right GPIB address).

    So I go to equivalent NI MAX or Agilent (Keysight connection Expert), proceed to part communication from VISA to either and manually, connect with the machine. And it works! If clear my computer is communicating with the machine at this point, but not of LabVIEW.

    This could be the cause, and what I might try? Thank you!

    Oh shit, I forgot about it! I solved the problem, it was actually a 'me' problem is not a problem of LV. Even my solution would not be to help someone else who finds it. I was trying to read from my instrument, but it is in synchronous mode, so it generates an error if you try to read her when a data point has not been loaded in its buffer. I did something unusual, so it was not a point of data loaded into its buffer.

  • USB thermometer works in Hyperterminal &amp; MAX, but not in my VI

    I have USB (Omega TJ - USB) thermometer.  I contacted with her success in Hyperterminal.  When I try with MAX, it usually starts working after the second attempt to read/write.  But even if I put the termchar 0xD and termchar_en to True, I still have to type my writing as 'C' back ' 20.2 c ' (20.2 C being the temperature) any idea why this happens?

    In addition, I go ahead and make my VI, very similar to that found in the labview tutorial - image shown here: http://zone.ni.com/cms/images/devzone/tut/a/e09bfd41228.gif I put it for baud: 38400, 8n1.  and I also write 'c', but I get the error 1073807339.  I tried to change the buffer without change in the results.

    I thought it would be a relatively simple task, but it seems that I am bad, or overlooking something simple.

    Hi Chknrckd,

    Also what could be the problem, is that the way hyperterminal sends characters (when you type words). LabVIEW will send a string at the same time, while that hyperterminal sends each character at a time.
