    NI PCIe-5140s

    Added that this is an NI card to original post.

    NI PCIe-5140s

    Dear all, I've inherited a machine with an NI PCIe-5410s card which functions on LV12. I'm looking for documentation for this card, in part to see decide if an upgrade in LV version is wise. Strangely, I can't find any documentation, so I guess the card is deprecated.... If anyone could help out, I'd be grateful. /dirk
  3. has the 'edit post' feature a minimal time on the new forums or has it always been like this? Karl, others will probably respond to your points in detail. Thank you for illustrating that standpoints in this debate are highly political and not scientific. Again, that is not a problem, just be open about it.
  4. I did, and that's why I asked the question. Unfortunately, you don't seem to want to answer it here. You started the topic, granted, question remains: what is your problem? See below before you hit reply. Does asking questions make things political? If it is Science that concerns you, how about the organic transistor of Schon from Bell Labs; or the South Korean cloning thing: did that excite you that much? Sidenote: how exactly does science go beyond politics? Who's funding science? May not like it, but it's the way it is. OK, bite to this then. I hypothesize that, based on you "0bama
  5. ok, so what is your point exactly? is it that you don't believe in climate change? the PICTURES OK? that you posted seem to show that there is continuous change. stop yelling please, btw. is it that you don't like the consequences that this climate change may have to your lifestyle? that's political, so don't complain about a couple of scientists gone bad. they're bad people, we all agree; doesn't necessarily mean the science is bad. is it that you don't share the political views of the people stressing this climate change, global warming? nobody likes being lied to (whether or not this
  6. Well, all you US folk seem to forget that it is also St Maarten. I'm going to wire up a latern and get myself some candy.
  7. since replying to this topic seems to be the only way of addressing these issues at times.... YES, I really, really, really, appreciate the time and effort the moderators put into this forum. I learned a lot, and I hope I helped some people too, in the course of time. No, I don't understand why something that was not broken (LAVA 1.0, or was it broken?) was "fixed" in LAVA 2.0. I remember a lot of topics, code snips, etc that used to be there (LAVA 1.0), which have been very useful to me, but which are just not so easy to find anymore because of alfa-bloody-fifth-dimension-rss, broken link
  8. headache coming up... so if I understand right, if I would load an image-saved-as-pixels from file, put it in an intensity graph control and have some property nodes on the diagram to set the labels of the axes..... I get /4/ data copies?? If so, is switching to a picture control beneficial? /d
  9. Ano, I don't have 8.2 installed anymore (and if you have any chance to upgrade to 9.0 you should so I haven't been able to test it. But here you go. No wrapper DLL's involved. BrowseForFolderG.vi
  10. Not in LabVIEW. I think LV's shallow learning curve prevents 'beginners' to think about design patterns. An extreme LV duct tape programmer is someone using a lot of local and global variables, 10+ frame stacked sequences, discards a main-program-while-loop as too complicated because there is a 'run continuously' button; uses only Express VI's (the baby-blue color spells: beginner ) and thinks the combination of a state machine with an event structure is overdoing it, because why would you respond to a Stop-ValueChange with Stop-case in the next iteration of the allready redundant MainProg
  11. Rolf: fair enough. LV handles so many things for you..... I actually only noticed this when I changed a Complex Double (which wasn't supposed to be complex) to a Single in an example VI which I wanted to send to the students in our group. My major concern was with their potential surprise of seeing number different of the number they entered. Anyhow, it all makes sense after all. Maybe I'm just not having a good day today. /d
  12. [Edit: just a couple of minutes too late....] I understand that not all numbers can be represented exactly, but the key to my puzzle is in the default display precision of SGL and DBL. If you configure a constant as a SGL with value 1.3 it defaults to 6 digits of precision. You can change the representation of the SGL back and forth to DBL, but it maintains it's 6 digits (always displaying 1.3) If you configure the constant as a DBL with value 1.3 it defaults to 13 digits of precision (initially showing 1.3) Changing the representation to SGL maintains 13 digits of display precision (no
  13. ok, I understand that it has to do with the # digits. but still this puzzles me: If I place a constant, change it's representation to SGL and enter 1.3, the constant on the BD reads 1.3 If I then enter any other value, it simply displays what I entered (as I would expect). If I place a constant, change it's representation to DBL and enter 1.3, the constant reads 1.3. If I change the representation to SGL, it shows 1.29..... If I enter any other value, it sometimes displays what I entered, sometimes not. Yet both constants have SGL representation. /d
  14. can anyone confirm (and explain) this behaviour: 1) place a numeric constant on an empty block diagram (defaults to 0, I32) 2) enter fractional number 1.3. representation changes to DBL 3) change representation to SGL In my case, the constant changes to 1.299999952316 (I noticed that this doesn't happen for all entered values.... 1.5 works fine) /dirk
