xabi started following Actor framework: User Event Error 1
-
I’m working on a project using the Actor Framework to remotely control an oscilloscope. The actor responsible for the oscilloscope overrides the Actor Core to run a loop that acquires data, which is then sent to the root actor for processing. The issue is that when stopping the root actor, the oscilloscope actor throws an error when trying to send the data (which is expected, since the root actor no longer exists). However, the problem is that when executing Stop Core—where the acquisition and UI loops are stopped—for some reason error 1 is generated and the actor does not shut down properly. On the other hand, when sending the Stop message, it does stop correctly. Any ideas? Thanks in advance! Generic Oscilloscope.zip

I guess it's issue with VIPM 2026.. I tried with other machine with 2023 VIPM and it installed fine. Now I'm looking for licensing details of Lua and looks CIT Engineering is not there any more.. Any leads on this @Rolf Kalbermatter?

Francois Aujard started following PCIe 6323 RTSI - Labview 2022Q3
-
Hello everyone, I'm having an RTSI issue between two PCIe 6323 cards. I upgraded my PC from Windows 7 or 10 and LabVIEW 2013 to Windows 11 and LabVIEW 2022 Q3. My high-speed acquisition is no longer working. I was using the counter on one card as a clock source for the other card via /Dev1/Ctr2InternalOutput. But it seems this option no longer exists in newer versions of DAQmx. I consistently get error -89125: DAQmx Start Task.vi "Unable to find registered trigger lines between devices on this route. If you have a PXI chassis, correctly identify the chassis in MAX and ensure it has been configured correctly. If you are using PCI devices, make sure they are connected with an RTSI cable and that the RTSI cable is registered in MAX. Otherwise, make sure there is a trigger line available on the shared trigger bus between the devices. Source device: Dev2 Destination device: Dev1" I can't find the RTSI option in NI-MAX. Does it still exist? Is it possible to synchronize the two cards using an internal counter? Thank you for your help Translated with DeepL.com (free version)

Can you tell me more about what the problem is with VIPM? Which VIPM version is that? And what error if any do you get?
-
Hey Rolf, one of such project popped up in our side and has old scripts in LuaVIEW.. Unfortunately the VIPM is not happy to open Lua4LabVIEW_Toolkit-2.0.5-2.ogp downloaded from https://www.luaforlabview.com/download.htm Seems it's not listed in VIPM.io as well. By any means you know last LabVIEW version it's successfully installed? We are trying with LV2023 64 bit. -BR- Ajay.

Sorry I never got back to you here. That error looks like the extention dll is missing. I would check to see if it is at the path specified in teh error message.

Mapping Enums onto SQLite Text type is intentional. The "Parameters" feature didn't exist back in version 1.7.3. Note that if you are converting data selected from the database, you can convert either Integer or Text as Enums, but with Paramaters (going into the database) one has to make a choice of type for Enums, and the choice I made is Text. You can still make Enums Integers, but you will have to use another method, such as "Prepare Statement".

I see. I recall that there was an update to the Python integration model in 2022.
-
@X___ Unfortunately it won't save as 2021, as Python object interaction is not available in this version (see screenshot). For reference, the 'Labview_Python_Bridge' works by creating and interacting with a Python Class/Object.

Hi, we just changed the version of SQLite from 1.7.3.65 to 1.16.0.115 and we found out this library have a bug, we believe. This happen when we try to query a record cluster including enum value. In the Execute SQL (Variant Cluster results).vi/Parse Parameters.vi, originally, the enum is return as Int; now it returns as String. This makes the output variant after goes through variant to data converter become invalid data. Sincerely, Thang Nguyen

Nice project. I want to try it out, but you seem to have released it in the post-SaaS decision of Emerson/NI 2022 version and that is a problem. Is it possible to release it in 2021 for us old-fashioned who did not want to be at the mercy of Emerson/NI's pricing whim? Thanks!

Thanks for the input. I'll look into it. I would like to add that I have created a small test application which I also have sent to NI as part of the support task. This test application works just as intended on my old PXI system: an indicator on the front panel updates from a counter on the FPGA counting up when the trigger comes. But it does not work on my new system. The indicator is always zero.

PXI-1084 trigger routing issue between PXI-6683H and PXIe-7820R
Miles-lava replied to codcoder's topic in Hardware
Bit of a long shot but is your FPGA initialising Trig_0 in any way, e.g. Setting it to F on startup to get it into a known state? I've just recently fixed an issue on my 1085 system where everything was running normally until I used a FPGA card to set a trigger. Once this had happened the trigger was reserved by the FPGA and I could no longer control it through DAQmx even if I closed and restarted the DAQmx tasks, but I also didn't get any DAQmx errors. -
Hi, So this is a blatantly repost from the discord channel but I'm getting kind of desperate here. I have opened an issue with the NI support function but I figure I might as well try the rest of the community here too. This is a copy and paste of my problem description which I have sent to NI and it is very similar to what I have written in the discord channel: I am building a new PXI-based test system that duplicates an older system which has been working reliably since around 2019. The purpose of this setup is to provide absolute time to an FPGA so that all FPGA read/write signals can be timestamped correctly. The timing architecture is as follows: A PXI-6683H generates a custom 1 Hz pulse using NI-Sync. This pulse is routed over PXI_Trig0 on the backplane. In the LabVIEW RT application, on the falling edge of the pulse, I write the next whole second value to the PXIe-7820R through a front panel control. On the rising edge, an FPGA loop is expected to trigger, latch that value as valid, and update the FPGA time function. Between pulses, the FPGA time is advanced using the FPGA internal 40 MHz clock. To verify that the FPGA loop has triggered, the FPGA sets a status indicator to 1, which I read back from the RT side. In the failing system, this status always remains 0. I also observe that other FPGA functions appear inactive. Based on this, my conclusion is that the FPGA is not seeing the trigger, or is not responding to it. Important context: The same software and FPGA firmware concept works in another chassis, a PXI-1062Q. The new system uses a PXI-1084 chassis. I am aware that the PXI-1084 is divided into three trigger bus segments, but both the PXI-6683H and PXIe-7820R are installed within the same segment. I have verified that the PXI-6683H can generate a signal. In MAX test panels, I can successfully drive PXI_Trig0 from the 6683H and read it back using MAX functionality, which suggests that the 6683H is operational and that PXI_Trig0 exists at least in some sense. I have formatted the RT controller and reinstalled software, but the issue remains. My main question is whether there is any chassis-specific routing limitation, configuration requirement, or compatibility issue in the PXI-1084 that could prevent a user-generated PXI_Trig0 signal from being seen by the PXIe-7820R, even when both modules are in the same trigger segment. So... anyone? I am hoping for a super obscure yet super easy solution here.

Hi, Thanks for the tip. They want to hire someone who can be a part of buidling the company as well so only in-house I am afraid.

My part of the world as well! (Columbus based) How committed is the company to hiring someone directly? My company has resources that could potentially help with this. It's outside of my personal wheelhouse, but I am relatively local and can travel to the client. The resources we have are a bit scattered, but I could be a local face. The project itself specifically seems to align pretty closely with work our CTO has before (wave equation, imaging analysis & CUDA work) -- everyone would be US citizens as well. So it might be a good fit skill wise, but unsure if they'd be willing consider something like this. If you think it might work, happy to provide some contact information and we can move this chat elsewhere!

My part of the world! Unfortunately, I don't have any connections to the realm you are talking about. But I would look at Northern Kentucky University (just across the Ohio river) as they have a good CS program (or at least used to). There is also Miami University (not to be confused with the one in Florida), Wright State University (where I got my MSE), and University of Dayton about an hour north of here in the Dayton area. University of Kentucky is about 2 hours south (Lexington, Kentucky), which is about the same distance from Ohio University (Athens) or THE Ohio State University (Columbus).

Living and working in Norway I am not sure about this; What would be the best way to recruit personnell (US citizens only due to security clearance requirements) with work experience in things like scientific computing, ray tracing/wave propagation simulation, tomography type of analysis - using C++/C# and GPUs (CUDA/OptiX e.g). in Ohio? (My first guess for this would be to look at former students from the mechanical or biomedical departments at the local Universities, but the feedback I have had so far on that is that the top students from UC and OU typically get recruited quickly and relocate...and that perhaps this would better fit someone with a computer science background...) The work involves data acquisition, signal analysis and motion control which are things LabVIEW-developers often have experience with, and hearing about this recruitment challenge I first thought about JKI e.g., but the company in question wants to recruit someone to work in-house, be located in Cincinnati (no relocation package)...and implement some heavy lifting using CUDA/OptiX or similar, so it is not a LabVIEW or consultancy job. Any tips (apart from hiring a local recruitment firm...), or someone who knows any suitable candidates (again - US citizens only)?

Hooovahh, Yes, you are right. Controls indeed need to be used in a development environment. I stumbled upon the fact that I could modify the control icon and save it even with only the runtime engine. I am more curious about how it is implemented, as this involves a knowledge gap for me.
