Using intermittent problems "invoke the node-> default reset" command to delete a table

I use the 'default' reinitalization invoke the node to clear a table after sending the data to a file. The next time that the vi is called the table should appear all items, set the default values. However sometimes the picture is not deleted and data since the previous call of the vi are still in the arrary, or at least it appears that way, since the same data for the previous time called appear in the file when new values are added to the file. New data looks good, as the data points in the table that I don't update appear with the old values. And again, it is an intermittent problem. I can solve this problem for a while in any case stop labview and re-run it.  Any ideas what's happening?

Thank you.

  • intermittent problem of the node constructor 1172

    Hi, I work with an Assembly (.net) using .NET Framework 4.0.

    I have the .dll support and my VI in the same directory on the PC. I am trying to go between two different .dll when I test my new code but the problem is that he works sporadically.

    I can have a whole day of work and when I'm trying to build something new all of a sudden the old VI who worked before no longer works and generates an error in 1172.

    I have LabView 2013 and 2015 installed, Windows 7.

    I also have a config file

    
     
        
           
        
     
    

    that will force the code to use the Framework 4.0 in the same directory and languages in the LABVIEW directory.

    This is going to do my system so unstable?

    Cason, I found the question now. MATLAB for the dll I tried was built with different versions (32 vs. 64-bit).

    When you use a 64-bit dll it is a must to use the 64-bit version of LabView and what 32-bit dll, use LabView 32-bit version.

    So I have to use the 32-bit dll because I can't use the LabView 64 bits (there is a problem when you use it as well as database connectivity tools).

    Furthermore, this incompatibility with the database has been underway for several years, I think it's time to make it work for 64-bit LabView.

  • problem to open and cancel a Subvi by invoking the node

    Hello

    I have a Subvi, which is runing in a while loop and it's calculation that finished in a variable time. So I decided to add the abort function to invoke the node. This works perfectly when the Subvi is running by its own but gives an error.

    1000 error to reference open VI
    Possible reasons: LabVIEW: The VI isn't in a State compatible with this operation.

    I found that there is a solution for this in the following link.

    http://digital.NI.com/public.nsf/allkb/790AC75B07D971ED86256C53007BDCE9

    So I added the Vi run invoke node in the main vi and abort VI invoke node in the Subvi

    as in the following excerpt, but I still get the same error. Think you I'm missing?

    Eureka. I found it.

    It was very simple.

    I just add the stop simulation in the simulation loop if time exceeds certain limits.

    Anyway, thank you guys for helping me.

    See you soon,.

  • Invoke the node: export image does not work in sub - VI?

    Windows 7 64 bit

    LabVIEW 9, 32-bit

    bug alert!

    See example attached vi

    The image of export invoke node only work while the Subvi is open, so called as a Subvi and the Subvi is closed this function fails to create an image.

    Using the graphical version express XY, I created an xy chart.  Then created an invoke node to export the image of the xy graph.  When I call this vi as a Subvi, it works, as far as the Subvi remains open.  If I close the Subvi and don't run the main vi, no image is created.

    No explanation why this would be?  LabVIEW 10 has the same problem?

    So the answer is simple, whenever an image is desired from a Subvi always use: invoke the node-> get image, in addition to any collection already implemented code to force labview to update the image

  • 3 laptops different ALL been facing intermittent problems with the USB ports.

    We have 3 laptops at home, running 3 different versions of winsows 7... Home, Professional and Ultimate. They have in recent months ALL given intermittent problems with the USB ports. A device that worked on a port stops working. It may or may not work on another port. A week later it could very well lead again on the port that wouldn't work. This applies to all types of devices.

    A few more questions:

    Is there a USB device that you use with all three computers?

    This problem occurs with all kinds of USB devices?

    The is the problem with all the USB ports on each laptop?

    Have you tried to reinstall the USB drivers? As in, uninstall via the Device Manager, restart your PC and allowing Windows to reinstall?

  • invoke the node (screw in a parallel work library)

    Hi all

    I'm evaluating a temperature probe. For this I must watch the thermocouple readings. Thermocouple is attached to the FP-TC-120 of temperature module. Moreover, I have to acquire data from the optical spectrum analyzer. I use 3650.VI to monitor the temperature and 86140 B Capture of Trace_Screen .llb (2) o trace data of OSA.
    I try to use Invoke node VI for Spectrum Analyzer trace data. For this, I specified the path to the necessary file as an input for the code. The problem is that the necessary VI (write Trace to File.VI) is within a Bachelor of law. folder and need codes to operate completely.
    It is when I run the code (and when the condition of stability is met) the computer asks me to save data of Spectrum Analyzer in a file called trace.csv. When I press ok, it simply registers an empty file with a header (Power (dbm) wavelength (nm)). Apparently it works in parallel with the other VI. How can I make use of the VIs within a .llb file with call node VI or should I use another VI to combine temperature monitor VI VI of tracing data.

    The second problem is with the temperature stability criterion. In the attached VI, I check if the thermocouple reading is within the range of stability of 0.8 degree 900 seconds. I want to change that. I have
    you want to check the stability of the temperature by comparing the final data with the previous ones. Y at - there no specific VI which should be used to check fluctuations of waveforms?

    Thank you very much

    Deniz says:

    Now, I struggle with timing. The problem is that if I put a timer inside a case structure, it disables the time VI

    This is not what is actually happening. What is happening is that the loop must wait until the delay function is completed before you can continue to the next iteration. There are several ways to solve this problem. Here are 2:

    • Instead of having a time delay within the structure of the case, use a shift register to keep track of the last time a trace has been captured. If the time is greater than or equal to 1 minute and you are supposed to be captured, and then do the capture and reset the timer. Thus, the structure of the case would be headed by 2 conditions rather than 1. It is a relatively simple change.
    • Place trace capture in a separate and independent loop. The case structure would be as is inside this independent loop. You must use a property node or a local as a flag variable, so that the trace capture can be triggered. For example, you must create an indicator of the output of the or less? function so that you can read the value in the other loop.

    I recommend method 1.

    PS, I just noticed that the "Trace Xfer" VI has already incorporated in writing in a spreadsheet file .  As it is, you will get a dialog box asking you for a file name. You can either:

    • Delete the entry in the worksheet in the "Trace Xfer" VI file as you do in your top-level code.
    • Delete the entry in the worksheet of your first level VI file and add a path control to the "Trace Xfer" VI and past in the path to the file you want to write.

  • Problem invoking the api rest of VCO NSX

    Mary I currently works with VCO and NSX for my license thesis and a few problems when you try to use the api NSX in a VCO workflow.

    I use the built-in VCO which comes with VRA 6.2 and NSX 6.1.3 all living inside a Vcenter 5.5
    I'm just getting started with this and at the moment I just want to create a workflow that performs a GET request to a < nsx-Manager-IP >/api/versions.
    I do this by using workflows of VCO HTTP REST she draws vco.

    First I ran 'add a host REST' and set the URL to < nsx-Manager-IP > who succeeded

    Then 'Add a REST operation' with/api/versions URL model that also succeeds

    To test this, I ran "invoke an operation REMAINS" and selected my newly established operation, that's where I met a wall,

    This workflow fails and throws the exception: connection pool stop (Workflow: call operation of REST / REST call (item0) #6)

    The thing is I'm having a very difficult time to find what means this error, so any help would be really appreciated

    More information:

    I tried to send the same exact request with the Postmaster and who returns the deal answer Yes at least by now I'm pretty sure that the error has something to do with something inside the VCO

  • iMac 27 "mid-2011 - Intermittent problem with CPU fan running at full speed and sleep mode.

    Hello!

    My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

    Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time. But once he starts to go in mode 'sleep', when I wake up, it goes right back in mode after a few seconds and that it will continue indefinitely until I restart the computer.
