I am reinstalling everything on a new computer. so this morning I go to get LV2018 and find this new download page
https://www.ni.com/en-us/support/downloads/software-products/download.labview.html
Okay that's nice and easy...
Except after I chose the version and hit the Download button NOTHING HAPPENS.
Is there some special browser plug-in I need to make this work?
Que tal comunidad tengo un problema al adquirir mis señales análogas de unos sensores de presión, bueno les explico todo trabaja perfecto entre sensores y tarjeta el problema esta cuando muestro la señal o mi presión en pantalla ya que el sensor no manda ningun voltaje pero en la pantalla aparece como su este estuviera llegando voltaje como si entrara ruido pero al mapear la señal o medir voltaje esta en cero cual sera el problema o porque pasa esto les dejo una imagen de mi programa
hello
I am trying to write a programme using Function Generator and Variable Power supplies, I use NI Elvis II+ and LabVIEW 2015.
I coud not configure the name of my device *Dev3* in the resource name as you see in the pic below.
I refreshed the Max.
I refreshed the resource name.
I rebooted my system.
Given this vi that controls a motor based on some sensor data, I have some logic that determines the next motor state (based on the previous state & some sensor input). Furthermore, I need to test/evaluate different logical methods to determine the best motor/sensor approach for our application. This currently leads me to the practice using nodes/wires to encapsulate the state logic into a subVi, then trying the sub in the larger test vi.
My question is, can I compose the logic in C and make this usable (by some means) to the test vi, instead of wiring the logic into subVIs? Since the logic can be distilled to primitive data types, it seems like it would be much faster to type the transition function into C than it would be to encode it into a subVi w/wires & nodes.
Am I making any sense here? I've been using LV for about four weeks now. I'm wondering if there is a method of "compiling" a function written in C into a node that can be placed into a vi. Thanks in advance for you help.
So, I recently downloaded the NI software bundle Spring 2019 because I wanted to upgrade from LabView2018 SPI1. To my disappointment, NI Package Manager doesn't allow me to choose a destination path and installs everything under C:/Program Files/ . Unfortunately, I don't have enough disk space on my SSD, so I wanted to have the option to install it on my other HDD, D:/.
This was possible when I installed LabView2018 SP1 in the past. Please note that I want to install the FPGA module with the Vivado 2017.2 compilation tools, so disk space is a serious issue...
Hello all. Forgive me for the somewhat basic question, but I'm trying to control an old magnet control gaussmeter (Varian FR41) and the old C code looks like this:
{
long temp;
int z1,z2,z3,z4,b1,b2,b3;
float b;
double gauss,hv=9555.,magconst=.069,Mass=171.;
if (ieeeinit()==-1)
{
printf("Cannot initialize IEEE system.\n");
exit(1);
}
gauss=sqrt(Mass*hv/magconst);
temp=10*gauss;
b=temp/10.;
z1=b/1000;
z2=b/100;
z3=b/10;
z4=b;
printf("\n\r %f %f %d %d %d %d",gauss,b,z1,z2,z3,z4);
b1=z2+z1*6;
b2=z4+6*z3-160*z2;
b3=(b-z4)*160+14;
printf("\n\r %d %d %d %d",7,b1,b2,b3);
ieeewt("output 08;");
ieeeprtf("%c%c%c%c\n",7,b1,b2,b3);
}
I'm having trouble with the conversion to LabView in two areas. First, the in the line
b=temp/10.;
I do not know how to reproduce the "." element selection in LabView.
Lastly, I can't seem to get the
ieeeprtf("%c%c%c%c\n",7,b1,b2,b3);to communicate with the instrument using the GPIB Send Message.vi. Is there another solution to sending characters to the instrument through the GPIB hub?
Thanks,
Jesse
I have a distributed application that I had sent to a customer, including the installation file with LabVIEW real time engine. After testing it, they wanted several changes, one of which included a sub VI not included with the original. I rebuilt the application, then sent them the .exe file. The customer deleted the previous version and copied the new version of .exe to their computer
The customer has commented that the file will not even run.
1. Is the problem because I only sent them the .exe (application) file, and not the .aliases and .ini (Configuration settings) files? I guess that makes sense, now that I read the type of folder.
or
2. Because I added a new sub vi to the program, do they need to have a installer file? I noticed one of the steps in the installer requires all files to be called out. This kind of contradicts the idea that if a customer downloads LabVIEW run-time engine, all they need is the application file.
or
3. Do they need both? Both files together was 1.2GB large, because I had to include an extra installer, DAQmx Application Development Support.
Hi, I am making a control panel for eight temperature controllers. The controllers communicate to labVIEW with serial communication. I made a subVI that has a while loop inside to display temperature values every certain time. In the main VI I call twice this subVI with independent parameters (inputs) and control the open/close of their front panels with buttons. Although, the Hierarchy diagram shows that both references points to the same subVI so I cannot open them independently. Can you help me, please?
Main VI:

I'm installing LabVIEW 2018 onto a new computer that I'm trying to setup for development work.
Whenever I open the project I get the following error:
C:\Source\CLV Station\Core\Source\WebServices\WebTool.vi (WebTool.vi)
NI GOOP Development Suite support for LabVIEW 2018 is missing and is referenced by the following VIs:
Twice, I have tried installing the NI GOOP suite to try to get rid of this error. I received the error after each installation.
The snapshot below shows that the VI Package Manager seems to believe that the suite is installed. However, when I load the project it gives me the error indicated above.
I would appreciate any help toward resolving this issue.
Greetings,
I have encountered a weird problem with LabVIEW 2018 SP1 (18.0.1f2) and the cursor in the development environment. The cursor is excessively large and pixelated. I believe it is being rendered at a lower resolution, and this is related to my high DPI screen. Please see the attached screenshots for examples of the problem. I acknowledge the fonts will be fuzzy and pixelated with a high DPI monitor.
Interestingly, this does not occur in LabVIEW 2015 SP1, which I also have installed. Please see the attached screenshots.
Summarized system information:
I am not running in tablet mode. I am not connected to any external monitors. I have read and tried the instructions in the "All the Main Application Windows in LabVIEW are Tiny" and the "Inconsistent LabVIEW UI Behavior with Multiple Monitors on Windows 10" knowledge base papers. If I disable scaling for LabVIEW, then the cursor is correct, but the front panel and block diagrams are tiny and nearly unreadable. I will mention, disabling the high DPI scaling fixed an issue I had with NI MAX.
I have seen the "LabVIEW and display 4K (3840x2160)" post as well. I tried halving the resolution and scaling, but then I get vertical or horizontal black bars on the screen. I also tried playing with the scaling and resolution, but regardless of the changes either the cursor looks good and the rest of LabVIEW is unreadable/unusable or the cursor looks bad and the rest of LabVIEW is readable/usable. I also think this is a different issue than the 4K monitor because only the cursor appears to be affected and I only have the problem in LabVIEW 2018 SPI.
Additionally, the cursor only appears to be large and pixelated within the block diagram and front panel. As soon as I move it to the menus or any context/pop-up menus/dialogs, the cursor changes to the system cursor and looks fine. Has anyone else experienced this issue? I am open to suggestions for potential workarounds.
Thanks,
Chris
Hello everyone.
I have more than one file but the listbox shows only first file (index 0 of the array). I would like to know how to bring all the values displayed in the listbox.
Thank you in advance.
version: LabVIEW NXG 3.0
My programs worked nicely yesterday but it went wrong today and there is no modification for my program. The error said:
The back-end complier for this deploy target failed with an error while processing this file. The compiler failed to update the code for a dependency. The file may be corrupt or there may be a bug in the back-end compiler. Consider undoing recent edits, closing and reloading the current project, or restarting the application....
The problem weren't solved at present and my program is needed recently.
Could anybody lend a hand? Thx very much!
Labview初心者です。
前任者の作ったプログラムを引継ぎ実験を行っています。
今までLecroyのオシロスコープを使っていたのですが、故障していまい、
新しくowonのXDS3302を購入しました。
Windows7
Lavbiew2014
LANで接続し、owonに付属していたLabviewの波形観測プログラムは動いたのですが、
今まで使用していた波形記録プログラムが動きません。
違いがあるとすれば、
ブロックダイアグラムで
owonのはIPアドレス
LecroyのはI/Oとなっていることかと思うのですが
どこを変更すればいいのでしょうか？
If I use the AQ7280 usb drive (like picture 2) or use the NI-VISA Drive Wizard (like picture 4), the MAX also can not find the usb devices.
Thank you

Hi all
I'm want to use UDP to stream torque data from an HBM TIM-EC module to my cRIO 9047.
I can stream data directly from the HBM module to my host pc using the attached VI.
I want to get this up running on my cRIO (Eventually on the FPGA chip), since I need to sample with at least 20 kHz.
The HBM module is capable of sending data with 38 kHz.
The challenge is to have no loss of data during the data acquisition. Any suggestions how to implement this?
I have an instrument that when I read it I get 32 bit floating point data back from the buffer. There are two pieces of data per measurement point and multiple measurement values returned within the buffer.
How do i convert this IEEE 32 bit buffer data into an array of numeric data using LabView?
I should get an array of values around +8.704706E-009
I have displayed the format and what i get in the attachment.
Today I started to have some weird problem with my environment. In about 5 hours I've got 36 crashes! How can I found the cause?
When I try to compile my FPGA project on LabVIEW, I get the following error message.
Due to bad installation or configuration, the compile worker does not have any compile
capability. Please fix any issues and restart.
I had gone through this website https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019XdISAU&l=en-IN as I am beginner in FPGA, I am not able to understand how to solve this error
please provide detailed explanation.
Thanks in advance.
