how to view control logic from a vi file
Hello there,
I'm new to Labview and I have a very large vi file which contains control logic for a wind tunnel. I'm coming from a FORTRAN programming back ground and used to reading codes in text line format. Is there a command in Labview to view the coding in text line format?
Thanks in advance
Regards

Can only display chart with date and current time, not test time
Hi everyone,
I have a very simply program in which I'd like to display the chart with the test time. That means that it the x-axis should start at zero (if I clear the chart data) and then increase from zero. However it keeps displaying the date and time instead. I tried everything in the properties and I can't modifiy this. Is there something that I am missing?
Thank in advance!

How to read settings from a file
I'm writing a data logger program that may be used to log up to nine or ten channels at a time. Because there is basically no way to remove channels from a task, my program requires that you get the setup right on the first try or you have to start over. I imagine that process would get old fast, particularly if the same test is being done over and over again.
So my question is, how could I save the control inputs, or the DAQmx task, or something to a file which could then be loaded instead of entering everything manually each time?
I have attached a VI from the standard examples which I have based my program on, and I have attached a picture of what I actually have.

What is the best way to deal with recording huge amounts of data?
I'm writing a data logging program that may be used for long periods of time. A typical test could run anywhere from days to months at a sample rate in the kHz range. So, a lot of data will be collected, but I don't necessarily care about all of it. If everything is running as expected for several days, then I don't need to keep the data from those days.
So my question is, what would be the best way to deal with this problem? All of the data will need to be looked over by a human at some point, so how hard would it be to start writing to a different file every day? Is there a way to do that which doesn't lose some amount of data while it is stopping one file and starting another? Is there, perhaps, a way to edit a file that is being written to at the same time?
I really don't know how to move forward, so any ideas or suggestion is welcome.
I have based my program on the attached, standard example VI, and I have included a picture of the logging portion of my code.

Report Generation Toolkit
Hello,
I purchased Report Generation Toolkit and I had to uninstall and reinstall the software because MS Office Report VI wasn't working. Now after the installation I can't get the VI to appear at all on my pallet. Would anyone have suggestions on what could be wrong?

Load Model.vi missing
I'm trying to follow the example in the below link to run a compiled simulink dll. I'm using LabView 2019. I've installed Veristand 2018 to get the model integration toolkit. However, when I open the example vi, I am missing a few sub VI's that are part of the MIT. I'm missing "Load Model.vi", "Get Model Period.vi", and "Take Model Time Step.vi"
The example I'm trying to follow is here: https://forums.ni.com/t5/Example-Programs/Running-Compiled-Simulink-Models-in-LabVIEW-and-in-VeriStand/ta-p/3889270?profile.language=en
Is LabView 2019 too new to follow this example? Any suggestions on how I can get these vi's? I verified that the MIT 2018 is installed...
Thanks.

Labview stop and program stop with enqueue
Hello application engineers,
I am encountering a boring bug and played around to find a solution, unfortunately, No success.
Enqueue and dequeue are used in my program (similar to the attached one, XY_B.vi). The program worked fine without the release queues, however, after adding the release queue to the end of the program, a boring bug appeared . It always shows the last data point goes back to the zero time when the program stop is clicked as shown in the attached photo (Program stop.png). but the bug does not show if the labview stop button is clicked to stop the program (Labview stop.png).
Could someone help with the issue?
Thanks.

Digital Thermometer Center309
I want to use LabVIEW to monitor the temperature using Digital Thermometer Center309 (Center Co.). But I have not been able to do that.
The thermometer used is shown below.
The USB used is RS-232.
The operation of the software(SE309) included with the thermometer has been confirmed.
I was able to confirm the USB connection with NI MAX.
I also tried to communicate with the thermometer using NI MAX's Visa Test Panel, Input/Output.
It seems that writing is working properly. However, reading does not work properly.
When I read and write VISA in LabVIEW, the operation stops at the reading.
How do I get the temperature from the thermometer?
Pleas teach me.
(I am very happy if the answer is Japanese.)

Timer counter does not update properly as called from SUB VI.
Hi,
I am having an issue trying to call a timer from a SUB VI. The timer counter works perfectly in a VI itself. However, when I make a SUBVI and call it in a new VI, the indicator does not update properly as a counter. It only updates at the end. Please check out the attached files.
Thank you for helping!!

Two data into "Write To Measurement" Function
Hi,
I like to capture Two signal data from USB-6366, and record as .csv. Now I implement "Write To Measurement" Function. But this function have only single signal. So I can not logged two data simultaneously on single log file.
Is there any method exist ? If so, please instruct how to implement it.
Best,

Error at Configure Serial Port at Property Node(arg 17)
Dear all,
i try to connect with an old temperature measurement device. I use an USB-RS232 Apdater.
I was able to read out the temperatures with the Visa Test Panel from the NI Max, after i tried several different settings.
So i tried to copy the attributes from the NI Max and set them also in the Configure Serial Port.vi
In the end i have a problem with the Property Node(arg 17). This is the setting in the NI Max:
Here are the settings in the Labview.vi ; the numbers of the property node i hope are right?!Her
Here you can see the error in the Labview program.
I tried also the other possible settings at arg 17 but i always get this error code.
Can someone help me with that? Why there are this differences in VISA test panel and Labview?
Best regards

Temperature against time
Hi, I'm working on measuring temperature against time in labview (of a thermistor). The data comes in as voltage and gets converted to temperature in the subvi. I'm not sure whether I should be using a waveform or XY graph for this. I've attached the block diagram and subvi.
Thanks!
