  1. Nothing wrong with Excel! https://interestingengineering.com/80-year-old-japanese-man-uses-excel-to-create-dazzling-paintings
  2. I don't have an answer for your activation issue, but you're not alone: https://lavag.org/topic/22358-nis-new-software-subscription-model/ https://forums.ni.com/t5/LabVIEW/LabVIEW-subscription-model-for-2022/td-p/4204448
  3. That's rather worrying then, given that Farnell is now an "Authorized Distributor" for NI.
  4. Ain't this it? https://uk.farnell.com/ni/777849-35/labview-real-time-deployment-license/dp/3701592
  5. NI Linux RT is just another Linux distro. If you can install Linux on your device, you can probably install NI Linux RT which comes with the LabVIEW runtime. I'm not sure what the licensing implications are. You probably won't get NI hardware driver support, however. The Zynq FPGA is a completely different beast. The only other widespread dataflow language in industry (that I know of) is Simulink, so... The best language is one that you are experienced and competent in. The next best language is one that you have resources and drive to learn.
  6. Some hardware has a minimal sample rate. Double-check that the "SampClk.Rate" property does return exactly 250 Hz -- If it's actually higher, then you'll never empty your buffer and it just keeps growing. Use a producer-consumer architecture (example: https://forums.ni.com/t5/Example-Code/DAQmx-Encoder-Measurement-with-Producer-Consumer-Architecture/ta-p/3493445) Your DAQmx while-loops should be dedicated to calling DAQmx Read.vi only. The data should be sent to a different loop (via a queue or a Channel Wire) for writing. Beware: Since you are writing waveforms but you discard some data chunks, your file timestamps will be wrong. When you send your waveform to the data writing loop, send the relevant TDMS Group Name too.
  7. They do provide a built-in image uploader, which we're expected to use instead of off-site links: I had no problems like this: https://stackoverflow.com/questions/36852665/adding-delay-in-data-acquisition-in-labview/36857051#36857051
  8. I don't have experience with Beckhoff products, but a customer asked us to integrate a UEI Cube a few years ago. I remember thinking that their API was a bit more convoluted than DAQmx. This customer got non-rugged accessories so they struggled a bit to get good shielding, but I have seen MIL-STD compliant hardware in UEI's product line.
  9. That is... different from my experience. I had an old installation of LV2017 which has no expiry. When I added the LabVIEW Real-Time Module 2017 to it in April 2020, it was given an expiry date of August 2020. When August 2020 came, I had to re-activate LabVIEW Real-Time Module 2017 (but not LabVIEW 2017). And this repeated itself in August 2021. My employer had been using the old NI Developer Suite for over a decade and this still kicked in -- we never had expiry dates before.
  10. This is unrelated to the LabVIEW version, and unrelated to perpetual vs. subscription licenses. In recent years, NI's license servers have changed things such that all activations are only valid until the next August -- Even perpetual licenses must now be re-activated annually. So if you install and activate those same older versions on a different PC today, they too will expire in August 2022.
  11. I used the Web module with SystemLink, but not with Python. It is somewhat (not very) responsive; there is a lot of room for improvement. See the 2022 posts at Not personally, but NI does have official DAQmx Python API. It should work: https://nidaqmx-python.readthedocs.io/en/latest/
  12. I used the NXG 5.0 Web Module (direct precursor to the G Web Development module) for a large SystemLink-hosted project. The biggest issue for me is missing functionality. Despite SystemLink touting Tags + Messages + Files as the 3 pillars of data transfer, NI did not provide a Web Module API for downloading/uploading files from/to a SystemLink server. I thought... "That's OK, I'll just use the raw HTTP API instead". And then I found out that the HTTP API itself was unfinished. NI provides a WebVI for making a HTTP Multipart request (which is required for uploading files), but if you open up that VI it simply spits out an error constant that says, "feature not implemented". So I had to implement it in JavaScript in the end. The next headache is the rigid UI. It is near impossible to get the UI to even resize with the browser window; the result feels rather unprofessional next to non-NI web UIs. The Web Module is fine for making very basic, static dashboards. But if you want to do anything complex/interactive/dynamic, you'll need to delve into HTML + CSS + JavaScript.
  13. It's more than "bordering spam"; it's a common tactic used by spammers in forums across the Internet: One account posts a link and another extols its virtues while speaking as if they are a 3rd party.
  14. VMware 15.5.5 and newer can run alongside Hyper-V: https://blogs.vmware.com/workstation/2020/05/vmware-workstation-now-supports-hyper-v-mode.html
