I am controlling an app through labview, because I am doing a repetitive process.
I need to listen for a window, so I can repeat the process.
Can anyone please help me in doing this?
Any help will be appreciated.
Thanks.

scb 68 terminal block (5 V between D GND and pfi)
I'm using two daq boards, 6036e and 6731 with a SCB 68 terminal block. If I check the voltage between D GND and PFI line of the SCB 68 terminal block for both daq boards, I can see 5 V difference between them for any GND and PFI lines. so, I can not use the trigger using GND and PFI line. Is it broken or normal?
FYI, so I'm using two PFI lines, which are not biased with 5 V, for the trigger. In that case, the only falling edge works no matter what i choose the rasing or falling edge for the trigger.

AI measurement problem
I have a small code which works as follows: DO up -> measure 3 AI channels -> DO down. Code works at some level, but I am having trouble with the results. It gives me voltage level without decimals. I have checked properties and there is 6 significant numbers accuracy. Tried some other tricks too but didnt get them to work. Any ideas?
2 channels should give -2.xx V and one channel 2.xx V
Instrument is Keysight U2355A

How does version control with LabVIEW VIs work?
Does anybody have experience with version control and LabVIEW? Since LabVIEW VIs are not text-based, how does it work? I would like to use git but I have a few questions:
When committing changes, does git recognize the differences in the VI or does it replace the whole file with the new one? Does this result in a large expansion of the repository?
Is there a possibility to merge different versions of a VI?
Or is there a version control that works better for LabVIEW?

LabVIEW執行檔在電腦跳電後發生INI檔內容錯誤
各位先進好
我日前遇到一奇怪現象
軟體使用者表示軟體執行過程中電腦發生跳電
之後軟體便無法正常使用
經過查證發現是ini檔的問題
原本的ini檔是存入15*10的二維資料
結果跳電後的ini檔變成只有1*1的一維資料
因此想請教各位一個問題
如果有一個執行檔有寫ini檔的功能
有可能因為軟體執行過程中電腦跳電發生ini檔寫檔不完全的現象嗎?

USRP Open Session Error
From time to time I get the error below when initiating a session with my USRP-2901.
There are no recovery from the error besides disconnecting the USB-cable and then re-connect it after a few seconds.
Is it a driver issue, Windows issue, USB issue or some problems with the hardware itself?
Any advice is helpful at this point.

Modbus - loss of communication
Hi, I'm doing a LabVIEW program for controlling 2 Variable Speed Drives, more specifically Abb ACS 880 and Abb ACS 580. I'm using the free Modbus library for the communication, with the Modbus TCP protocol. The program works fine for some time communicating with the both drives simultaneously, changing the operation mode, giving speed and torque references. After some minutes working the communication suddenly is lost. I would like to ask what might be the possible reasons for this loss of communication?
Thank you in advance.

Error occurs only in build, not in IDE
I just spend a lot of time figuring out a problem with some LabView-Code, because the error only occurs in the build of the project. When running the VI in development environment the error is just not generated!
In the screenshot you can see, that a property node is used to set a splitter bar at a specific place.
If the resolution is not high enough, the property node throws error 1358 - but only in the build, in the IDE the problem is just ignored! That made it pretty hard to find the place, where I have to deal with the error (as I now did).
Can anybody explain the reason of that behaviour to me?

LabVIEW and Windows Server 2016 / 2019
Does anybody have any experiences running LabVIEW Executables on Windows Server 2016 or 2019?
I know that this is not officially supported and I already got a call from NI but they said they have no experiences regarding this topic.

How to find the index of a changed array control
Hello, I have a array control on my front panel containing switches. Once one of the switches is flipped I would like to find the array index of said switch, along with the value. ( I am using an event structure to coordinate this)
I am using this to send on/off events to my GOOP "DAQ object".
Any insight or examples would be greatly appreciated.

Timed Loop and Time representation in waveform chart
Hello,
I have been reading Labview explanations about how to work with "Timed Loop" and how to use "Waveform Chart" but I'm not able to achieve what I want.
What I want:
I want to sample each 5 seconds with "Timed Loop" and I want to see the data in my "Waveform Chart" each 5 segonds.
What I see (Image 1 and 2) is that each sample is shown like it happened each2-3hours!! I've tried with/without autoscale in X axis.
What should I do to see sample at the correct time it was taken?

Cell Size of Occupancy Grid Map
Hello Community,
I am working on applying the A* path planning algorithm to an occupancy grid map. My grid is 16×16, and it is supposed to represent an 8×8m area, with cell size at 0.5m/cell. But currently, the grid is 1m/cell.
Please, I need help on how to achieve the grid size of 0.5m/cell.
Attached below is my code.
Thank you.

DAQ Assistant
I am using LabVIEW 2017 along with the USB-6210 to collect a voltage signal and encoder counts. I am using the encoder counter(PFI0) as the trigger to collect 8000 voltage signals. The signals are being collected and analyzed properly so I know that the counter is working or I wouldn't have any data, but for some reason I cannot understand yet, the encoder signal count is not being updated and passed through my VI. I use the same setup for several different VI's ... basically identical and those work without issue. Has anyone experienced this erratic behavior?

Any ideas why it is failing?
