• get the limits of the step of a sequence in a labview program

  I am writing a labview program to access the different properties of teststand sequences to automatically enter the data of the sequence for the documentation.

  The step.limits.high property is very difficult to recover from the teststand programmatically sequence by simply using the sequence as input file.

  Does anyone know how to get the limits on a stage in a movie file?

• Change the properties of a cluster element inside an array of clusters

  Hi all

  I have a table of cluster that has the shape of a line with different elements of the screen.

  A list or a tree would not have made it, so I had to use a cluster and make a.

  The problem is I want to change not only the text but also the color of the text.

  Individually.

  I found this:

  http://www.NI.com/example/30904/en/

  But it changes the property in all groups in the table, not just the one I need.

  Some people have the same problem:

  Obviously, even if in a table/list or a tree, you can change the property of an individual

  cells (font, color), you can't do it in a cluster network, by a kind of magic.

  the property of an element of the cluster (font, color) are all connected together, so made

  the use of a table without value.

  A possible hack is available using masking of control, a visible setting and the

  other invisble, exchanging their position, whatever. This is a hack you have to perform,

  Therefore, add another code to maintain.

  Is that still the case, or is it now a more formal way to manage the individual cluster

  Properties, not only its data? After all it is a common example of a real life which should

  managed by Labview. In my opinion.

  David Koch

  Altenbach says:

  One of the elements could be an indicator of 2D about the same size image. You can create text in any color using the features of the image.

  Here's what I had in mind. Seems to work very well (I would refine the border picture fonts, etc., but this should help you get started).

  

• ActiveX - LabView from c#

  Hello

  I create a program in LabView in a program already developed in c# that uses ActiveX to control a laser machine.

  The first thing I see in the program is the initialization of the ActiveX Server and equipment system:

  Laser = new LaserAxApp();

  LaserSystem = Laser.System;

  I found a refNum in labview with LaserAxApp, but in their properties, I found systems within the ILaserAxApp property. But also, I found a different refNum called laserengineLib.ISystem which is another reference to class as AxApp.

  which choose to continue implementing my program of c#?

  Thanks in advance,

  Thanks anyway... I managed to find the answer.

  It works with the properties and methods in the ActiveX menu in Labview. To answer my own question, the result is to use iLaseraxapp and ilasersystem refnums.

  Here is better explained:

  (1) start the laser with refnum laserengineLib.ILaserAxApp

  (2) use the open automation to open and

  (3) bind it with a node of the system IlaserAxApp (true visible) property.

  And that's all. Then you can use lib system even for event reminder reg and ilaserdoc for loading a file of xlp laser.

  I'm doing my thesis in Zedboard for the development of a test for DDR3 memory and verification. For this I need to set up a base of dedicated on NI Measurement Studio LabVIEW graphical user Interface.

  Theme: Algorithmic Szudy of test set-up for DDR3 SDRAM with a Xilinx architecting.

  Here, I made my algorithm Xilinx SDK. But I need to create a graphical interface using labview. To run these programs. Please let me know how I can do this.

  1 or is it possible to directly access the SoC architecting using Labview. If yes how?

  2. or if I have to do the coding of Xilinx SDK and how do I run this code using Labview?

  Please give me a detailed answer. As I am new to labview. I m not understanding how to start with. If you have any design example please share with me.

  Thank you best regards &,.

  No you can not grow directly in LabVIEW and deploy this program to the Board of Directors Zync. NOR has their own material base platform Zync (cRIO and myRIO) but the tools to target these tips are specific to the hardware implementation OR and will not work with other hardware. Develop an interface for another hardware platform is a lot of work and must be adapted for each unique flavor to a new hardware platform. And NEITHER does not support this for other devices.

  If your option will be to develop an application with the SDK Zync for Zync ARM controller and provide a form of communication interface (serial port, TCP/IP, or similar) to this application you can send commands to LabVIEW for your embedded application.

• Wrapper DLL c# LabView

  I need to receive data from monitoring of the eyes, and I had a horrible time with the SDK.  I first discovered that LabView does not meet events that have a source, and then I discovered that LabView does not show methods or properties that have (or are?) credits.  I guess I have two options... I can do a LabView DLL by using the shared variables to communicate data to my program, or I can do a very small DLL using the .NET development kit.

  I'm not a c# person and will have a hard time to pick up.  The code below works as an EXE file.  Someone here would be able to change around to be a DLL that sends the e.* args to an event that LabView picks up?

• LabView program in command prompt

  Hi all!

  First of all, here is my config:

  -Dev PC: Win 7 32-bit

  -Target PC: Windows XP - 32 bit

  -LabView 2009 - 32-bit

  I need to design a program which one will be interfaced with an ERP. So it should not have a GUI and must be controlled by sending to command (MARKET / STOP / ABORT...) and send some status info (data of 10 or 15). For now, I'm only able to launch my program of command prompt and of the arguments passing. But I'm not able to send orders after this and disable the HMI.

  Is it possible to do it with LabView? If yes how? If not, how can I interface my devices to LabView and manipulation program of these devices in another type of program that allows you to do?

  Best regards

  Harold.

  On the only way that I know of to two programs to reliably talk to each other is using TCP.

• Problems with graph XY 'forget' field properties

  I have problems with a graphic XT in my loop.

  The graph has 10 locations which at any time can have anything from 0 to ~ 1000 points, often a few plots will have much less ploints than others. There is an option to select the user to view all items or just the most recent game.

  My problem is I want the chart to reflect the data input and a single point during an update, so I have a string of points rather than a line.

  When I click with the right button on the chart and go to properties, I change the style of point of full circle and turn off the interpolation of the line. I then click on save these default values and save the vi.

  However, once I run the vi, the graph keeps parcels 1 through 9 (not ground 0, this remains as I want) to have no displayed point and the line of interpolation on.

  Anyone had this problem before? Ho solve you this problem?

  I know it can be fixed, because I had this problem a few months ago on a similar vi and after weeks of struggle, I solved it, but I just do not remember how I did it.

  Thanks for any help, at the moment I can't post any code. Note that the chart data show is all perfectly fine, just the properties of the plot are forgotten.

  HI DarraghCorrigan,

  With regard to the problem expressed in your initial post:

  "once I run the vi, the graph keeps parcels 1 through 9 (not ground 0, this remains as I want) have no displayed point and the line of interpolation on."

  This is due to a bug in the software LabVIEW by which all changes that are made to the parcel properties (for example to change the color of a conspiracy) will not be retained, except in field 0 that is not affected. Our R & D department are currently studying this problem so that it can be fixed in future version of the software. The solution recommended for this problem is to pragmatically set parameters of track at the beginning of the code using nodes of property.

  As I understand it, is not the main issue you are experiencing. If you are setting the properties for a field (using a few nodes property described (e) which are then deleted or rewritten on a XY Chart, I understand, is that there is no way that LabVIEW can remember and preserve these properties.

  As you rightly suggested, a way to easily overcome this problem would be to define default chart properties, so that when you remove/rewrite a piece and then add it again, it is always by default these properties. Unfortunately, it is not currently possible to do even if it was recommended as a suggestion of product is a feature that is to the study of implementation in future releases of LabVIEW.

  I think that the question you need to address is the fact that you're at some point reset the graph by sending an empty array to him such that the set of your property are lost. If you can find and remove this section in your code, you should be able to solve your problem.

  I hope this helps.

• can labview call a test module

  Problems with a test dll that works in testing, but I get an error when you try to use the Assistant in labview, however I can use the protypye call library function node there.  Problem - the openComserialPort function (char * comPort, ErrStruct & err), how can you difine the parameters for the ErrStruct & an error of the game.

  Next Question, because this Dll runs in the bench trial, is their anyway export to work in LabVIEW.

  This Dll runs in the test bench, as export their anyway to work in LabVIEW.

  Yes it will work in LabVIEW course.

  How can you difine the parameters for the ErrStruct & an error of the game.

  It is a "pointer to a structure. You must specify the structure of the ErrStruct. Please include the description of this dll to help you better.

• Wireless on Satellite C660d-14W after clean instalation of Win 7

  Hello

  I bought a toshiba satellite c660d-14w off the coast of a friend and reinstalled a fresh copy of windows 7 x 64.
  After installation, the laptop does not recognize any material (graphics, wireless network card, sound) so I slowly tried to install all the drivers for all.

  However, no matter what I install for the wireless, it just doesn't seem to work.
  Installed the driver from realtek RTL8188CE, driver lan wireless on Toshiba website and have set the network connections service car and restarted it and still nothing.

  In the Manager of peripheral devices, network cards, I have two entries:

  Realtek PCIe FE Family Controller
  &
  Realtek RTL8188CE WLAN 802.11n PCI-E NIC

  Suffice to say that they are working properly and have the latest drivers but I have no wireless access, does not display the icon in the status bar, and I just get a generic windows error message when you try to configure it manually.

  Help, please!

  Yes, the wireless network card seems to be properly recognized in Device Manager.
  The Satellite C660C-14W supports the Realtek RTL8188CE WLan chip.

  You said you do not have access to the WLan
  Did you check the availability
  Control Panel-> network sharing Center-> the settings of map (left)

  Here, you should see the wireless network card
  Is - this visible?

  If Yes, go to properties and uninstall the TCP/IPv6 protocol and use only TCP/IPv4

• Error 1050 trying to use load 'filename' in matlab script node

  Hello

  I get error 1050 when Labview is trying to load a text via the node of matlab script file.

  I have all ready checked for her on this forum and google but found nothing. I also did this: http://digital.ni.com/public.nsf/allkb/2B3FF46C8512C4F786256CF30071BE53 and tried to use dlmread and much more.

  The thing is that I need the node matlab script for reading a txt file that Labview made a chart with 1 single table, draw the it and export a jpg image. I can't really use the 'export picture' or 'get image' function for cause of Labview, I need the whole route chart (these functions only take a snapshot of it when they are run).

  It's my code I use:

  Data = Load ('file');

  VPP = (Data (1:2000,1));

  XSIZE = (1/2000);

  Plot (0.0005:0.0005:1 VPP);

  axis ([1 0 5 - 5]);

  print ('-images ', 'graph.jpg');

  The usual matlab load to load txt files and print to print the jpeg format. The code works in matlab, but not in labview

  And Yes, I use windows 7 and legal versions of matlab r2009b and Labview 2009

  Hehe, I thought about it

  Path must be converted to a string and skip the ' in the file.

  Question 1:

  I want a VI that takes a picture of the camera when I hit the Boolean value and keeps it for later use. When I start my VI it does not show a picture when I run mode to run culminating it works very well. I've also attached the VI if you want to try it.

  

  Question 2:

  In the end, I want a VI that captures the 5 different images using different Boolean 5. I was looking for a structure with 6 cases (do nothing + 5 capture image case) when I hit one of the Boolean values. I couldn't find a (structure of the event and conditional turn off structure seems intresting, but I could not understand how to use them, it is still possible). So my simple solution was to copy the structure of business 5 times. That would work no doubt, but not not seem a clean solution (what happens if I want to capture 30 frames).

  Ruts

  Hello ruts.

  I made a little adjustment to your code.
  It is not yet optimal performance wise, but it should give you at least one output.

  Please note that you must have some features of waiting in your loop and try to keep your outside the loop (if possible) initialization code.

  Can you test and let me know if problem 1 is resolved?

  Regarding question 2:
  -Do you have previous experience with LabVIEW?
  If Yes, what have you tried already?

  -Have you taken classes (1 Core, Core 2,...)?

  You have access to online training materials?
  If you do, then a good starting point to know the structures of the event and other things is the next page:
  https://lumen.NI.com/nicif/us/LMS_LOGIN/content.XHTML?du=http%3A%2f%2Fsine.NI.com%3A80%2Fmyni%2Fself...

  -Are in the image of the camera even?
  How should they be displayed for the user?

  Side question:
  For what will be used this acquisition in the end?

  Probably the best way to start would be a kind of event-driven state machine who acquires different images.

• Making of FDD adjuster GPIB of Agilent E4438C

  Hi guys, I am very new to Labview, but very interested to use it to control my Agilent E4438C signal generator. IM generating a signal to 2.7 GHz with a bandwidth of 20 MHz. Im interested in the FDD, so I had planned to produce another signal at 2.4 GHz.------.

  The problem is, I only have one of this generator. It is-

  -Can I use labview to control the signal generator to generate a signal to 2.7 GHz and store in labview and generate another 2.4 GHz signal and store it. Then the multiplex in labview itself and then control/inject the signal in the generator of signals for transmission.

  IM generate this signal signal Agilent, software studio.

  Please advice on this. Thank you.

  Can I use labview to control the signal generator to generate a signal to 2.7 GHz and store in labview?

  Yes

  Generate another 2.4 GHz signal and store?

  Yes

  Then the multiplex in labview itself?

  Yes

  and then control/inject the signal in the generator of signals for transmission.

  Unfortunately no.

  As I understand it, a signal generator or a function generator can generate a signal which is a function of time. For example: Sin(2*pi*t*f)

  Where f must be set as in your 2.4 or 2.7 GHz signals. Because we want to do is combine the signals to give a resultant of the 2.4 and 2.7 GHz signals, there's no single f conponent. so we can not specuify for the signal generator.

  How ever there is something called an arbitrary signal generator, where you can spend the waveform data, and this can generte the signal. LabVIEW can certainly gather your two signals combine both and then pass it to an arbitrary signal generator. But unfortunately the signal generator can not do the job.

  So I guess that there are a number of options.

  Buy an Arbutary Signal Generator... or another generator of signals.

  Sorry I could more than summer help, but if you have any further questions, the questions or points we give a cry.
