I have a 2D data of an image of size 1000x1024 and I have a 1D graph of size 1x1024. How can I plot both of them in a single plot/chart? Both the data are in the form of an array.

Assalamualaikum warahmatullahi wa barakatuh Abang-abang dan Kakak-kakak sekalian

Saya sedang merancang sebuah simulator pengoperasian turbin uap dengan LabVIEW. Saya ingin membuat tampilannya dapat memanggil VI simulasi yang berbeda yaitu VI sistem pendukung turbin uap. Saya sudah membuat semua sistem pendukung turbin uap dapam bentuk VI. Kira-kira saya harus menggunakan apa untuk membuat tampilannya seperti sub menu yang dapat menampilkan VI lain???

Terima kasih

Running two programs simultaneously

$
0
0

I’m trying to run two programs simultaneously in the same Labview window. One of the program is measuring the airflow through a USB device connected to the computer. The other program is acquiring sound through audio jack. I have inserted the sound acquisition program into the original or main program which measures the airflow. After insertion, only the sound acquisition program runs and displays sound signals. But the airflow program is not working and even not displaying in the graph. Here also I have attached the screen shot of the front panel and block diagram. 

 

Could anyone help me to fix this problem?

 

Thanks,

Scaling time axis on a chart

Hello everyone,

 

to scale the x axis according to the refresh rate of the loop i previously used the Xscale.multiplier node. In a new version of the program i used the same principle and it scales the x axis in some wired way and i cant figure out why. Does any of you have an idea why?

 

Regrads,

Phillip

How To Stop Analog Read and Acquire Whatever Have Read? -LabVIEW

$

Hello NI Guys!

(sorry if I use same question, I am afraid that different "Select Location" leads to different answer area. So, here, I use "Select Location": LabVIEW)

 

I am using NI USB 6002 and LabVIEW (I tried on .Net and ANCI C also).

I am doing Analog Input Continuous Data Acquisition, with rate 1000 Hz and Number of Samples of 10,000. --> So, the time to read needed is 10,000/1000 = 10 sec.

 

Sometimes, I want to just stop the data acquisition after 7 sec or less (not yet reach 10 sec or the 10,000 samples after I click Run or Start). 

But, after I click Stop button (in LabVIEW), the reading is still continuing until it gets 10,000 samples.

 

Is it possible to stop it immediately and I get whatever the Read have acquired? 

I mean if I stop after 7 sec from beginning, so I get about 7000 samples instead of 10,000 samples.

 

I have tried to set Timeout to less than 10 sec, but the error said "Some or all of the samples requested have not yet been acquired."

 

I open for all possible open answer.

Is there any method I can "interrupt" the Reading? Any other methods with same purpose are welcomed.

 

Thanks you Smiley Happy

how to create an start and end position for a device to control its motion.

Hai 

I want to create start and end positions i.e I would be able to change the values as required.  example- if I say start position as 10µm and end Position as 30µm and should happen in that way for any number.

I used a numeric indicator with that I can only change value. can u help me with which commands I can control start and positions of the device.

if possible can u please attach example VI how to create start and end commands.

I attached Vi image u can look at that.

thanking you.

HI, I've got a customer that wants to read NFC tags (in particular a NFC reader ACR-122U).

I don't have any experience with NFC.

Does anyone know how to communicate with these NFC readers using LabView drivers?

Save the array data in compact Rio 904x

Since the C Rio itself acts as another PC , I'm not able to save the array data in the desktop as csv.

How do I tackle this ? There should be a path within the Compact Rio .

unbundle array

I have an array of clusters.  I am trying to programmatically change a value in an array of clusters.  I have a lot of applications for this but wanted to give an easy example to see why this isn't working and if maybe there is an easier way to do this.  This is just a boolean value that once turned true then turns false after recording a numeric value of which index this happened on.

 

 

Duda al realizar máquina de estados con LabView utilizando la DAQ 6008.

Hola,

 

Tengo que realizar una aplicación que genere trenes de pulsos con diferente frecuencia, en diferentes pines de la USB 6008, para ello he hecho una máquina de estados que en cada case ejecute un subVI diferente. La función de los subVI es la de generar el tren de pulsos con una frecuencia diferente en un pin diferente de la tarjeta.

 

Pero solo funciona en el primer estado, cuando paso al segundo y al tercer estado, el subVI no realiza la función deseada, y no entiendo por qué. Adjunto tanto la máquina de estados como los tres subVI, si alguien sabe donde esta el problema le agradecería que me lo indicara...

 

Muchas gracias de antemano,

 

Saludos!!

 

 

Executable should not run without a license

$

Hello,
I am developing an add-on toolkit, licensing it using Protection Plus 4 from Software Key and packaging it using VI Package Manager. It is working fine.
 
On the user side, after the add on is activated with the license file(development license), they will be able to develop using the toolkit. If the user tries to build an executable using the VIs from the add-on and run the executable on another desktop then it should not run. the application should show an error asking for a license (which we are calling a deployment license). We will then provide a license (deployment license) for them to activate on that system and run the executable. The user should be able to build an exe and run on that system but it(exe) should not run on another system(deployed system) without a license(deployment license).
 
Can you suggest any possible way to achieve this ? 
Thank You

VI breaks during cleanup

$

Hi everyone!

 

I have a VI which breaks if I clean it up with the embedded solution (hitting Ctrl + U). I have found out that if the VI's name is short enough, then this does not occur. Also, if I remove all broken wires (Ctrl + B), it fixes the VI and cleaning up again results the same error. Can you confirm it please? I have attached the necessary files to reproduce the issue.

 

I'm using LabVIEW 2018, 64-bit version.

AI Current DAQmx Create Virtual Channel Measurement Issue

$

Hello, 

 

I'm relatively new to LabVIEW and have been experiencing an issue with getting all of the virtual analog input channels I have set up to output to my data file. For some reason, only some of the channels read out to the data file and their channel names do not stay with the measurements.

 

In the VI below titled "AI Current Test.vi", the data output file only shows three channels instead of the six shown in the VI and they are all unlabeled. In the VI below titled "Test VI 5.vi", the data output shows the four channels seen in the corresponding VI and they are all labeled with the DAQ module # and pin #. 

 

I'm stumped as to why I'm seeing this issue with "AI Current Test.vi" and would appreciate any help you could give me. I'm not getting any errors, but the output file is not generating correctly. This VI is messy because it is a component of a larger VI I'm using for a test in the near future. As I said, I am fairly new to LabVIEW so my work is clumsy. 

 

Thanks!

4072 capacitance verification

4072 capacitance verification: The 270pF verification fails. The calibration executive verification program does not open, short and null the lead resistance in the automated program. I put in the actual capacitance measurement with the test leads and capacitor and still get a failure at 270pF. When I test the 4072 manual on the front panel after performing the short, open compensation and null it reads correctly. Should a compensation and null be added to the automated procedure.
