Request to suggest online training
Hi,
I am currently using labview to capture image using a basler camera. I can take single image but need to take sequential images. Additionally, I am planning to use multiple camera and take image simultaneously for all of them. Meanwhile, I have no significant knowledge on labview.
Can you please suggest me a online course which can help me to learn image acquisition technique using labview?
Your feedback will be wholeheartedly acknowledged.

Eleven Ways to Update an Indicator from within a subVI. Their Relative Performances and Quite Far Reaching Consequences...
Yes, I know, you wanted to do this some day. So I did it for you. Just run (and then stop) the Main VI from the attached set (Saved in LabVIEW 2016 32-bit). I suspect (and hope
) the numbers will be quite a surprise and even a shock, especially for the fans of one particular method and some very aggressively promoted frameworks which use that method.

How to stabilize Voltage input
Hello All,
I am new to Labview. I am trying my first project that consist in measuring pressure from a transducer. The output of my transducer is 4- 20 mA and I am using the USB 6229 card.
I am using a 250 ohm precision resistor so the signal converts the 4-20 mA current into 1- 5 V. The problem is that the voltage values that I acquire oscillate a lot: For example for an expected 1 Volt input (equivalent to zero pressure), I read in labview an oscillating signal from 0.095 V and 1.05V. It represents in my sensor an unacceptable variation (about 20 psi). However, when I measure the voltage in the pins from the DAQ module using my multimeter I read a steady signal of 0.995 V for zero pressure.
I appreciate any help with this

There's a problem to Use ALTER Query to Rename the Table
Hi.
I was trying to rename my table by query.
So I found 'ALTER TABLE old_table_name RENAME TO new_table_name;' query on the internet.
But it cause error.
I try other functions like
ALTER TABLE name DROP [COLUMN] column_name
ALTER TABLE name ADD COLUMNS
and it work fine.
I don't know why I can't change my Table by 'ALTER' statement.
Is there anybody know the reason?

Producer consumer structure with event loop
Hello, please I want to realize a consumer producer structure with loop event. Because I have a main VI which in function when a button is pressed launches a sub vi as described below:
- Action B1 Launch VI1 with its front panel after treatment,
- Judgment VI1
-Action BP2 run VI2 with this front face
The structure according to my research will have to be conceived with a queue design.
The BP1 will have to launch the sub vi image processing and the BP2 the sub vi Control command, the sub vi command and supervision 1,2,3 are pus VIs of the VI command and supervision. The main VI is Synthesizer
Thank you

Serial port on laptop for serial communication
Hi,
For I student school project, I would like establish a communication between labview and PIC micro controller via serial port. I will use only Rx, Tx (please see the attached picture). My notebook does not have serial port. There are two options:
1. Using the standard USB serial R232 adapter in to USB port
2. Using a serial adapter in to ExpressCard slot which creates native serial port
I do not know which of these to buy.
The option 1 is cheaper, but not sure whether it will works (whether Labview will detect that serial port).
The option 2 theoretically should work (but not sure too), because the manufacturer states ("will add a serial COM port as if you had a native port on your laptop")
Which option do you recommend me. Anyone of you has tried the serial communication using the USB-Serial adapter or ExpressCard adapter on laptop?
Thanks for help.

Set number of plots in Waveform Chart (scripting)
There is a need to set number of plots in multiple Waveform Charts in multiple VIs. Scripting wold help if I could figure out how number of plots can be set
Please advice how the problem can be solved.
PS: I believe similar question would be razed for XYGraphs but so far I am stack with Waveform Charts.

triggered output
I want to detect peak from the analog input, and once there is a peak, output a pulse immediately. but it seems that the while loop obtains a certain number of sample one time, how can it output pulse immediately?

Class control greyed out
Today, I found that all of the class controls (and indicators) in all of the VIs for a certain child class in my project are greyed out like in the picture below.
The code still functions fine. I have resaved the class, and entire project, but the greyed out icons remain.
I can replace them with the class control from the project, then they are back in full colour.
Its not causing any issue (that I am aware of), but I just cant figure out what it means, or how to remedy it without deleting and replacing the offending controls.
Has anyone seen this before?

Error -1074000000 Agilent 3446X Series Acquir Triggered Multiple -113 "Undefined header"
Hi there,
I am trying to carry out a multi-points measurements with a DMM Agilent 34461A connected to my PC via LAN cable. I have tested the examples downloaded from Keysight website, including the VIs namely Series Acquire Single and Series Acquire Multiple, and both are working perfectly fine. However, the Series Acquire Triggered Multiple shows the following error:
Error - 1074000000 occurred at Agilent 3446X Series.lvlib:Error Query.vi and the posible reasons suggested in that message are as follows:
Instrument report:
-113, "undefined header"
+0, "no error"
I have checked in the forum to find similar cases, but I could not find any clue to short this problem out. Any help is really appreciate it.
Cheers

LabView Real-Time Startup VI vs Executable
Hello together,
I have a problem which I want to explain with the added picture (LabView Project).
Is it possible to start the VI's "Bilderkennung.vi" and "Bilderkennung_NI.vi" in parallel to "Tubis_WS1819.vi".
So in other words: "Tubis_WS1819.vi" is on my computer. And my target is to start all the three VI's with one click. Is this possible?
Maybe with the Real-Time Startup VI vs Executable?
https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000P9mySAC&l=de-DE
Can anybody help me with this?
If you need further information please write it in the comments.
Thanks in advance!

Unexpected value - is this known issue 544257?
Hi community,
I am getting an unexpected output in data 2 OUT in the snippet below:
As you can see, data 2 OUT consists of a "2" but should consists of the "1" in Element.
Inserting an always copy dot into the wire leading to Element inside the inplace structure fixes the behaviour.
The known issue reads as follows:
Inplace issue can occur when using LabVIEW 32-bit on a 64-bit operating system.
Running a VI that calls a subVI containing a Call Library Function Node to the kernel32.dll IsWow64Process can cause the returned value of the dll to be incorrect.
Workaround: Adding an "Always Copy" dot before the control that is wired to the Front Panel Terminal within the subVI fixes the issue.
Reported Version: 2014 Resolved Version: N/A Added: 08/08/2016
I am indeed running LabVIEW 32-bit on 64-bit Windows.
But as I don't consciously use a Call Library Function Node, I thought I'd post here maybe providing additional info on the issue.
Is this the right way to go about this, or is there a place for bug reports?
Best regards,
Florian

Duda selector en máquina de estados
Buenas!!
Estoy programando una máquina de estados en LabVIEW, el funcionamiento es sencillo:
En el primer estado lee tres entradas digitales, y en función de la entrada digital que se active, el programa irá a uno de los tres estados, si se activa la variable "value frec. 1" debe ir al estado 1, y así sucesivamente..
El caso es que no entiendo como programar el selector para que en función de la entrada que lea vaya a dicho estado, me vendría bien algo de ayuda...
Adjunto lo que llevo del programa (solo el estado inicial)...
Muchas gracias de antemano!!

Unable to include IMAQdx development support to installer in LabVIEW 2019
I created a runtime installer which includes LabVIEW, VISA, IMAQdx and Vision runtime for my application. Everything works fine in LV2018. But when I upgraded to LV2019, the installer shows that it could not find IMAQdx development support 18.0.
Then I clicked OK, and thought maybe it will auto upgraded to version 19.0. However, it seems like I can't add or find NI-IMAQdx Development Support in LV2019.
And I'm pretty sure I've installed VAS and IMAQdx driver correctly since I can see them in NI-MAX>Software.
Can anyone provide feedback on this? Otherwise, we can't upgrade our customer's computer to LV2019. Because it can't then snap pictures or configure cameras in NI-MAX.
The attachment is the lvproj file which has the installer in Build Specifications.
