  1. hooovahh -- what you're talking about is one of our options. Shaun -- we hunted around and those commands don't seem to be available on LinuxRT On top of the "standby" issue, after much back and forth with NI, we discovered that the system drive in the IC isn't removable. And it can't be encrypted. While we probably could have worked around the former, the latter is a show-stopper for our user. So, looks like we're ditching the NI "Industrial Controller" and going to someone else's "Industrial Computer". Plain jane Windows 10, 2 removeable drive slots, all of which will mak
  2. Hi all (no, I'm not really retired yet, lol), My latest toy is an IC-3173. I need to be able to programmatically (LV, of course) put it into a reduced power state (analogous to Windows standby/hibernate/sleep). And then "wake it up" every hour for 10 minutes. I'm running LinuxRT. Does it even have a concept of standby/hibernate/sleep? Cat
  3. So I'm upgrading from LV2016 to LV2019. Or attempting to, anyway. I have to use the offline version, and it keeps bailing at something like "ni-opc-support", and giving me a very unhelpful, "check your internet connection" message. Hello, this is supposed to be an offline installation?!? My other complaint is that I've installed every version of LV since 2.5 in a "LabVIEW" folder -- no version number added -- and I can't figure out how to make the NI Package Manager let me do that. So I've ended up with 3 or 4 different LabVIEWxxxx directories (depending on how far things get before
  4. We "upgraded" to Windows 10 version 1903 (from 1803 or 1809, I don't remember) and iperf3 went from ~450 MB/s to ~2 GB/s. Yay! Unfortunately, 1) the IA gods have not deemed 1903 worthy so we're not supposed to even have it installed, 2) there is question of whether this a fix, or something that will disappear in the next version, and 3) ironically, 1903 is causing issues with various types of hardware NICs (not a problem for us -- so far). But, for the moment, we've got something that works. Thanks to all for responses, and thanks to Gribo for suggesting iperf3. It's made i
  5. We could try running iperf, just to confirm it's the loopback adapter and not the code. But as I said, we've run the same code with 2 hardware NICs (10G) connected on the same computer and it works fine.
  6. The point of the loopback adapter is to use TCP to communicates to pass data between two different executables ( one C and one LV) on the same machine. The machine has 2- 1G and 4- 10G physical network adapters. Can you explain more what you mean by "link could be fully local"?
  7. We've set the loopback adapter the same way we've set up hardware NICs (at least as much as is applicable). I'll confirm that QOS and Nagle specifically have been dealt with. The C dev tried fastpath (even tho it was supposedly deprecated a while back) but that didn't help any. The computer has a very fast CPU. Two of them, actually. I guess the implication is that the hardware NICs are doing something the CPUs can't.
  8. Hi all! Long time, no talk to. 🙂 I'm supposedly retired, but then decided to go over to the Dark Side and become a contractor. We'll see how long that lasts... Current issue: A C developer and I are sending data via a MS loopback adapter between a C app and a LV app on the same machine (Windows 10). Past iterations have worked great (after that little bug in LV11 was fixed). The new system, however, needs a much higher continuous data thruput -- somewhere in the neighborhood of 900 MB/s. The loopback adapter is topping out somewhere around 500MB/s. If we switch from
  9. I use ini files. If I have complex data types, or large amounts of data required, the ini points to files where that data is stored. Also, LabVIEW annoyingly creates an ini file for every executable, so I figure I might as well use it. Cat
  10. Crud. I replied to this, but it never showed up in the feed. Huh. Anyway, yes, I'm turning this over to one of our C folks to deal with. I'm not sure if I can get the .NET version past our Information Assurance zealots, but a regular old dll I can call with a CIN will be fine.
  11. I just discovered that my latest needs-to-be-done-yesterday project requires communications via an Apache Qpid broker (v0.4 and AMQP 0-10). Since I didn't even know what AMQP was before yesterday, I'm a bit behind the curve on this. I have downloaded LabbitMQ, but I'm assuming that won't work with Apache Qpid? I was hoping that the whole open standard thing meant that different implementations of AMQP should be able to talk with each other, but the following link regarding interoperability between the two seems to say that this often isn't the case. There is a Native AMQP client fo
  12. Thanks for the process walk-thru. Unfortunately when I first read it I didn't know enough for it to help. Now it make perfect sense!
  13. Grrr. Yeah, the schedule change messed up my plans there. Hopefully next year I'll be there and can buy you a belated round.
  14. Wow. So after a day or so of flailing around I finally got this working. I think I only ended up making 2 changes to the Example.vi, the rest of the time I was trying to figure out all the networking stuff to make it actually work. Some of that time was spent combing thu this link for little hints. Some was spent figuring out what firewall setting I needed to turn off. Along the way I learned about symbolic links and how to configure an Apache web server. It was fun! Thanks hooovahh! And thanks to everyone else who contributed to this code.
  15. Maybe it's because it's Monday and I haven't recovered from either Cinco de Mayo (tequila) or the Kentucky Derby (bourbon) yet, but this one is twisting my little brain. After years of managing to avoid LabView and the Interwebs, somebody got the great idea of running some of my code via a web browser. Sure! I say, LabVIEW's got stuff to do that! Three hours later and it just ain't working right. I've read all sorts of things like: http://zone.ni.com/reference/en-XX/help/371361M-01/lvconcepts/ws_distributing/ http://zone.ni.com/reference/en-XX/help/371361L-01/lvhowto/enabling_t
