  1. sounds like they were too busy updating NI Logo and colors to implement VISA. Oh well.
  2. That seems reasonable. I have a wrapper class and pass back a pass/fail numeric and a status string, but now thinking back it might have been more appropriate to just pass back a standard labview error cluster. In my case, the python wrapper can be run from either LabVIEW or directly in python. The thing i struggle with is passing back real-time status that normally is provided in the terminal via python print statements when python scripts run stand-alone. I'm testing an approach that just sends these via a UDP session but I haven't found a way to override the Python print command so that it prints to both the terminal (python scripts) and to the UDP session (LabVIEW VIs).
  3. What type of instrumentation and data acquisition systems does your lab work with ? Mostly VISA type serial/gpib/LXI instruments or mostly data acquisition cards / PXI chassis type stuff?
  4. This isn't enticing you to upgrade from LV 2009?😀
  5. I would investigate cosmos. I haven't migrated a complete project to it yet but I'm implementing data collection, storage and telemetry GUIs to it for a new project working with python and FPGA programmers. A lot of the python programmers use python and it as a replacement for LabVIEW/TestStand. I haven't used their Script-Runner (TestStand-ish stuff) but the current version is highly capable for data collection, saving, presentation, limit checking. They are working on cosmos 5 which will run in a docker container and have web based gui's
  6. Ok. I misunderstood. But maybe there's something in there that can help. I remember having to do a lot of work arounds with callback VIs to get printing a panel without a prompt for filename to work. Attached is a 2014 version. Win10PrintPDF2014.llb
  7. If you are using Win10 you can try the VI(s) in the attached LLB. We typically create a "print" VI that shows all the controls, decorations logos etc we want to print, then run the VI in this llb. I threw the llb together real quick...hope everything works. Win10PrintPDF.llb
  8. This is a long shot here, but do they all need to run in the UI thread but their preferred execution system is set to "same as caller" and then something gets screwed up when they are called by dynamic dispatch in the runtime? What happens if you set their preferred execution system to "user interface" and retry.

    Things I Hate

    agreed. As part of my trials and tribulations with MAX I had to repair NI VISA. With NIPM18.5? no option to do that so they recommend uninstalling and reinstalling...fair enough. Tried that and NIPM wanted to uninstall LabVIEW..wtf. Upgrading to the latest version of NIPM (19.6) provided a better experience allowing you to repair installs now.
  10. MAX That is all.
  11. Is the latest version Is there another higher version somewhere because that one seems to still have the issue.
  12. Has anyone used IPFS as a tool for storing and distributing test data (multiple gigabytes)? My use case would be to run tests that store data on local windows machines and then distribute that to other users who may have linux, windows etc and also to a centralized archiving location. The users and test machines are in a relatively strict network environment and most users machines are locked down. Some of the linux users may have elevated privileges to install things like ipfs but I'm worried about a typical windows user who may want to get the files easily without having to go through a bunch of command line steps to install ipfs on there machine after requesting elevated privileges.
  13. Thanks for the quick response. its a rather annoying problem. I think this may have been the problem but wont know until I test again on Monday. You are correct that its a PM320E. And so far their driver has been a pain. The suspect command is the error query the parent class implements by default "SYST:ERR?" but PM320E requires ":SYST:ERR?". A nuance (nuisance) that I failed to notice. PS. I think I may have borked the instrument up by upgrading the firmware too. Oh well thats what you get for trying to get something done before a holiday weekend.
  14. I have an issue where reading the VISA Instr Property "Intf Type" of a USB Instrument hangs for about 40 secs: followed by an asynchronous VISA Write hang for 2+ minutes! The timeout on the VISA instr session is set to 1000ms. Here are the other details of the session: and here's a snip of the VI: Any idea why these long timeouts are occurring? or why the 1000ms timeout is being violated for both the Instr property call (no idea what goes on under the hood here) or the VISA write.
