• How to display data series changed after each step in labview gui, that is to say after the match point fantasy, after substring etc.

  Hi, I have a labview GUI that receives data serially through VISA and basically chops to the strings and realize games until I have values that I'm looking for. I have then convert Ascii string in decimal and feed the new values to a waveform. However, I discovered that some of the output values are incorrect. I checked this by pulling data through Realterm.

  Is it possible that I can see the modified data after each step in the user interface so that I can find where the problem is? I created indicators after each step, but they do not display data, I guess that its because the data is moving too quickly.

  I am very new to labview and struggled through every bit of this GUI, as none of you regular posters know. If you can suggest a solution, please know that I will probably ask more fundamental questions in order to implement your solution.

  I enclose my GUI with a screenshot of the same data through the Realterm. Basically any where you see xxxx TR TR or W xxxxW, know that it is the data between them is to say xxxx that corresponds to the data of interest. Everything else is ignored.

  I suspect that the problem lies in the string to decimal conversion and where 3 digit values increase to 4-digit values. That is, all values of less than 850 are correct but it is the maximum value is reached. My values are expected to reach 2500. Any help would be greatly appreciated.

  You have other debugging tools available to you.  You can use the run culminating to slow down the code and show you the data flowing from each wire.

  You can create a Subvi, which takes the data of each wire and written to a log file if you can review it later.

• Challenge! An email from LabVIEW GUI for anyone aged

  My elderly neighbour was recently in place with a small laptop (running win7 starter) and a hotmail account to keep in touch with loved ones. She is in her late 80s, and has never used a computer before. She can drive a tractor and shoot moles but was never able to navigate his Inbox in hotmail. (the text of the tiny Inbox is lost in a sea of ads and junk).

  The obvious solution is a LabVIEW front end! Something that looks like this http://pawpawmail.com/learn/ but uses a free e-mail server.

  I have very little time to produce something, so anyone has led to a webmail using LabVIEW server before? Anyone can start the ball rolling with a code here? All members of his family live hundreds of miles away, so any help would make a wonderful change to his life.

  Thank you very much

  What is http://www.eldy.eu/

  If this does not work with Hotmail, it's probably MUCH easier to simply organize a cheap POP compatible e-mail account than to write your own e-mail program (as fascinating as that may be).

• How can I track SequenceFailed from my LabVIEW GUI during execution of the sequence?

  I develop a LabVIEW graphical user custom interface, and I want to have a big success/failure seeing that reflect the current state of success or failure of the test sequence runs. My test application is a Burn-In that takes 8 hours. He could shut up red on the first step that fails.  I noticed there is a Boolean RunState.Root.SequenceFailed in TestStand, but I don't know how to work of LabVIEW, or if there are other, better as well.  This should be easy!

  Thank you

  OK, I'm really close, I think I have almost, but I have one last question, you are invited to do so by your last response. Where can I access engine callback 'SequencePostStepFailure '?  I can see "SequenceFilePostStep", but this isn't the same thing I think (?).

• Run a GUI without installed Labview labview

  I created a labview GUI and I need to my supervisor and monitor evaluation
  my camera prototype using this interface. I am in Ireland and they are in Berlin.

  Can you please indicate if it is possible for them to get a version of Labview to
  run this GUI only? If so, I will also build an application in my GUI (or rewrite my GUI)
  to enable them to do this? They can get a free trial for 7 days if its inappropriate.

  You can extend it to 90 days by checking the box and filling out the form when the 7 day period appears.

  Also, you can just reinstall the evaluation to get another 7/90 days.

• User Message message of Labview VI interface running on another thread

  I have a Labview GUI, which displays information on my oven.

  It's the thread that runs on the background it querys my oven, then I save variables stationglobals and then send a message to the user interface. It works very well.

  

  Now, I made an improved OVEN that not only monitor but also controls the oven. It is written in labview.

  on the above example, I use a statement for the user of Message interface:

  RunState.Thread.PostUIMessageEx (UIMsg_UserMessageBase + 1, 0, "",StationGlobals.ovenDatum, True)

  Where StationGolbals.ovenDatum is a container with the numbers and strings.

  Now on my Labview code

  

  I already have this wire in labview. So my question is... Can I just wire up my container in the ActiveXdataParameter ovenDatum or what I need to do some sort of conversion. ? I just do it?

  Problem solved after trying and you are looking for a solution...

  

• How to send a variable for Labview TestStand?

  Hello

  32-bit Teststand 2014

  32-bit Labview 2015

  Not sure if a matter of Labview and Teststand.

  I created a simple labview VI that has an indicator of success/failure.

  I created a simple teststand when having a success/failure of test with the labview VI as the file.

  I have a labview GUI that runs the teststand sequence and indicates if the sequence whole success or failure as a popup message.

  I have disabled reporting teststand.

  On the labview GUI, how can I show an indicator that my test pass/fail success or failure after the step of the sequence is over?

  If this can be done during the execution of the sequence, then how to display an indicator that my test pass/fail success or failure after the entire sequence ends?

  For example,.

  If I run two digital tests in my sequence. 24VDC testing and other tests of 3.3Vdc. After the execution of my order, I invite myself just at the end if the two tests either success or failure. However, if a test fails I will not be able to know the man who. I want to be able to tell which test failed with an indicator on my labview GUI and not a teststand generate report.

  I'm not sure if it's something to teststand I need installation with local variables or elsewhere in labview. I don't have a whole test report, I want to just the user to see an indicator that a particular functionality test adopted during the teststand sequence.

  Any help would be greatly appreciated.

  Thank you

  
  

• LabVIEW Runtime engine

  A strange thing has happened here: we have an old PC installed with a full version of labview software. An engineer has developed a Labview GUI. We can use this GUI to connect with our controller card using the RS232 port.

  Now, we want to use this labview GUI on another PC. I think it is unnecessary to install labview in the new PC software, but a labview runtime engine. Okay, so I downloaded and installed the runtime of 8.5.

  However, the GUI doesn't have to establish communication with my controller card... MISTLETOE can still be opened but no communication with my Board. No error as well...

  Can someone give me some advice?

  Thank you very much!

  If your application uses the functions of NI-VISA, then you will need to install the runtime of VISA on the target computer as well.  Way the easiest way is to create an installer that includes the runtime of LV and the execution engine VISA.

• Multitask acquisition using NI USB 4432

  Hello

  Is it possible to perform tasks DAQ of tension HAVE (1) and (2) accelerometer at the same time using NI USB 4432?

  I am trying to program a LabVIEW GUI to read analog voltage and acceleration at the same time with the device. As the nature of the tasks is different, I put two 'DAQmx create Channel.vi' in the same pattern, with specifying one as 'I-voltage-Basic' and the other as "I-acceleration-accelerometer. When I run the VI, error - 50103 appears to help run the VI.

  Thank you.

  SH

  The USB-4432 has five input channels that share the same timing engine which means that they will share the same timing and synchronization. The five input channels are all part of the same atomic analog input on the 4432 subsystem. Even if the types of measure are different, you can add them to the same task. If you want to treat tension and acceleration differently (for each type of measure), index the strings in the array of channels acquired after your Read DAQmx.

• Data acquisition using the USB-GPIB 82357 B interface for 4395 impedance Analyzer has:

  Hi all

  I tried to communicate Analyzer 4395A impedance with interface USB GPIB 82357 B using the command of expert keysight and Labview module tutorial. I couldn't able to find orders of SCPI (Standard for programmable Instruments orders) for 4395 A impedance Analyzer in the expert keysight command. Please help me on the subject of what are the other possibilities to acquire data from the Analyzer of impedance 4395 A using the interface USB GPIB 82357 B.? Is it possible to get LABVIEW plug & play drivers for USB-GPIB 82357 B interface? Our main goal is to control the parameters of impedance measurement and draw F vs IZI and theta vs F as well as get parameters of equivalent circuit on a PC with LABVIEW GUI.

  Can't wait to help.

  Hello!

  I agree with 'heavy '. For more information on how to program a 3rd device contact the manufacturer because they have the knowledge. Unless there is already a LabVIEW driver for this device, you would have to implement that yourself and need information from the manufacturer.

  Regarding your question if the GPIB-USB is unsuitable, it is quite easy to answer: If you want to communicate with a peripheral GPIB NI GPIB-USB can do this. But you would probably need a driver to use the GPIB of meaningful communication bus.

• -System 17500 our Exception memory

  Hello

  I see strange behavior when I start TestStand. I get an error-17500 "system memory Exception was thrown" during the execution of the step of "Create a plug-in cache" in the sequence 'Initialize model Plugins' in the ModelSupport.seq. Here's the kicker: I only see this error when I try to run TestStand via a graphical interface of LabWindows/CVI. I don't see this error when you run TestStand sequence editor or a LabVIEW GUI I use TS 2012 and 2012 of the CVI. I'm rnning the parallel model. When I look at the performance of the Windows Task Manager, I don't see memory problems. I've uninstalled and reinstalled TS and CVI nothing helps. I hope someone else can have experienced this problem o rhave possible an idea of what is the culprit. I'm running out of options.

  I've attached a screenshot of the window of runtime error.

  Thanks in advance for your help,

  Jim

  Doug,

  Thank you. This seems to have solved the problem.

• C# activeX

  I have a project that must translate into the joint of c# code in LabVIEW GUI (CSharp_EventLog.pdf), doing some basic code shown as EventLog.PNG, but seems not working do not. I send events server side, but this piece of code only gets no answer. I'm not familiar with ActiveX controls, and c#, need some suggestions on:

  1 at - it hurt with my LabVIEW code, why there is no response from the event? Read c# code, it seems class cast and/or Automation refnum mount? don't know how to code in LabVIEW.

  2. in call back vi, the event data are the variant, I expect string.

  Thanks in advance.

  Jason

  It seems that you do not receive the event data, but the reference to the event object. You need to convert ActiveX object, not string. Then you can work with the activex object: get properties (property node should show Date field similar c# is evt.) Date) and call methods (GetEventKey (evt)).

  You can't write something in c# like ToString (evt). Maybe you can, but you will get the same hexadecimal number 64 bit, not the event data. You write ToString (evt. (Date) - get evt first Date field, and then display it as string.

  To convert, you need constant class specifier. Copy TCEVENTLogger... control point vi, convert it to a constant and select class ActiveX correct (something like the TCEVENTLOGGERLib event).

• Output of a Matlab script

  Hello everyone

  I work on a project for school and had a question regarding the output of a Matlab Script node. I have data that is stored in the form T(:,:,i) is 3D data which are calculated in the script.

  The main thing I want to do is output, so I can graph on a façade of Labview. I want to display an image in 2d with a third dimension represented as points on the 2d image. (2d space with the 3rd dimension in temperature).

  It would not make sense why I am doing this in Labview but I have a set built for Labview GUI and it is an extract of things I want to show. I included a file for special graphics, I am trying to show in the end.

  I'm sorry I am still learning the ropes of Labview.

  Hi Jakeyboy1,

  Here is a link that shows how to send a table to 3 dimensions of LabVIEW, but you should be able to easily change the schema in the article to go through the process.  In the article, the first table of auto-index 3D of the sample code to assign a T(:,:,i) within the script environment.  LabVIEW then uses another script node to deal with 3-Dimensional table built.

  You can enable this process.  Off the first script thread knot out the length of the 3rd dimension and which feed the Terminal N of a loop for.  In the place the script node loop that reads T(:,:,i) and outputs the 2D from the node table.  You can plug this on loop for and autoindexing should create the 3D chart in LabVIEW.  From terminal N is the length of the 3rd dimension.  The table resulting in LabVIEW must be identical.

• standalone application for the acquisition of data using the NI DAQ card

  I did a stand-alone application in labview GUI for data acquisition and processing of the signal. If I have to run this application in any other computer which should be all installed software other than the labview runtime engine... CD DEVICE DRIVERS OR alone must be installed or do I have to install any other software of data acquisition using the data acquisition card OR?

  Thanks and greetings

  You need only the racing of the engine, the device for the device drivers, maybe need pilots VISA if you make serial or something of this nature, you may need the channels or tasks created in the measures OR and automation if you created the it.

  There may be other things you'll need depending on what you include in your code and what tool kits that you have installed.

• VBAI Interface - Get Image-> Dest Image inspection

  I have a complete Vision algorithm built in Vision Builder AI and programmed a VI in Labview that started the algorithm and results used to calculate. It works very well. Connection between Labview and VBAI is correct and the results are updated. Now, I want to show the image of the VBAI in my Labview GUI using the VI 'VBAI Interface - get Image Inspection' of the Vision Builder AI toolbox. Everything I try to connect at the entrance of "Image transfer" of the VI I am unable to let it run and give an image appears. See attached screenshot for details.

  -What type of entry how can I put a link to get this working VI?

  -Where can I find more detailed information in the context-sensitive help on all these VBAI VI toolkit?

  You must use IMAQ create to create an image. You can see an example of this in the case of Vision Builder AI under API Examples\LabVIEW Examples\LabVIEW API example (local) .vi

  Hope this helps,

  Brad
