• The 1473R CAN be used with the real-time operating system of NOR?

  Hello, I am trying to determine if I can use the OR 1473R framegrabber PCIe FPGA in a PC based computer time real OS OR. Anyone know if this is possible? So I think that it should appear to the OS in real-time as a target FPGA that can transfer the data via DMA, but I wanted to make sure the drivers would work in real time of NEITHER.

  I appreciate any info on this!

  lukepike,

  Yes, you can use this device with real-time OS of NOR.

• Updated in real-time with text of exec system indicator

  I was wondering if anyone knows how to get LabVIEW to update an indicator of text with information from a command prompt in real time?  So, as if you ping IP show he ping and not just wait until the end to update it.  I try to have a batch file that processes the code displayed on screen so that the user can see that she is running and that it is not frozen.  When I ran the test originally she had a cmd window pop up and show that information was passing.  Since I opened the program with the exec system, it no longer displays anything so I thought that if she showed in a text indicator the problem could be solved.

  Thank you

  Help for the system Exec VI

  (Windows) To use a DOS command, insert cmd /c before the command.

  Then try this way the system Exec VI

  cmd /c 172.18.81.54>"C:\temp.txt ping.

  Change the IP address to your needs.

  The quotation marks around the path is necessary if you have spaces in the path of the file.

  Now when you do this you will get nothing back from the exit of stardard, because you have redirected it.

  The results should be read from the file.

• Error-307650 during a sequence in real-time with API LV

  I created a basic real-time sequence that checks the time it takes a signal reach a certain threshold.

  

  On the side of the LV, I use the API to call this sequence. I make sure that all channels and settings are defined as in the examples. However I get 307650 error that says "NEITHER VeriStand: Index was out of range." Must be non-negative and less than the size of the collection.

  ' Parameter name: index.

  Any suggestion to help here? THX. Code is attached.

  There are two problems here:

  1. The Stimulus profile editor is not indicating that there is an error with this sequence, although there is a. Note that the variable InitialTime is used in an expression, but is not declared as a parameter or a local variable.

  2. you get an error at runtime because of it, but it's not terribly useful (index out of range).

  You can fix this by adding a local variable of InitialTime to your sequence. I dropped the CAR 338386 about this bug.

  Once you do this, there is something extra, you will need to set in your VI which runs the sequence so he could get the results of the sequence properly. You use correctly the value of the sequence name to read the back of the sequence Variable. You use the Session name used during the deployment of the sequence. Which does not match the name sequence.

  To get the name of the sequence, use VI to get all the names sequence on your session profile of stimulus to get the array of names for all of the top level of the session sequences, then index on the first point, given that you only use a single sequence. Example below:

  

• Vision in real time with USB2?

  Hey guys,.

  I'm stuck to decide on a method of image acquisition.

  My project requires real-time imaging, but it is on a netbook, except that USB is out. Ethernet is only 100mbit so no gige.

  I tried a few Comsumer s level USB cameras that I slept here and all seem to have about a half second lag in all lighting conditions. Is there a solution for me?

  I tend to avoid the acquisition of vision with the USB.  I don't know what the limits are.  I know the that most consumer webcams are not enough good quality for machine vision.  There are a few industrial USB cameras, you might want to look at.

  Can you put a firewire card in your netbook?  It would probably be your best option, because there are a large number of firewire cameras and they are very easy to use.

• Display in real time with a delayed recording LV6.1

  Hi, I need help with LabView 6.1

  I have a hardware module FieldPoint where I read 8 channels for thermocouple. I want to display the value of the thermocouples in real time (or as close as I can manage) all saving the values in a CSV file at discrete time intervals (every 10 seconds). I am able to display the values in real-time, but the recorder real-time records, produce a lot too much data. I'm able to delay the recording interval, but in bulk then display in real time!

  The following example shows a method I've tried. The delay time in the loop of logging seems to delay the entire program. I also tried to use the loop of the logging of a sequence (using a simple delay of 'Wait') structure and a structure of matter (with a counter and only do the loop of logging real when the counter gets to 1). I tried to configure synchronous display without success.

  I'm having no luck and wonder if someone could point me in the right direction?

  Ah, the benefits of time.

  I think that I managed to create a solution for me using a different tact. Instead of using individual meters of delay, I used a "trigger time" approach as demonstrated in this thread;

  http://forums.NI.com/NI/board/message?board.ID=170&message.ID=286988&query.ID=6280650#M286988

  Currently, it is limited because it will allow only a delay of 59 seconds between the readings, but this should be relatively easy to solve. The solution works continuously update the display with a slight delay to help cope aging computers, and then the button "Log Data" is selected writing worksheet function is called second pushed together as selected. Quite a simple and elegant solution I think.

• GetDiskSpace on real-time operating system

  Is it possible to query the free space on the disk in a PXI system running the operating system in real time.   I get a lot of linker errors when trying to use the GetDiskSpace function which works under Windows. (In Labview, it is apparently something called read Volume information but I was not able to find an analogue to the CVI 8.5)

  Jim

  Hey Jim -.

  The problem is that GetDiskSpace is implemented in the Toolbox of programmers, who is not yet supported on Pharlap.  However, you should be able to pull parts off toolbox.c (\CVI85\toolslib\toolbox\toolbox.c).  All the work to get this function is done by the GetDiskFreeSpaceExWin32 API function, which is supported on Pharlap.

  Take a look at the source code and let me know if you have any questions.

• problems in real-time with 6534

  Hello

  in our application, we use a PXI-6534 card to acquire datas. With 20 MHz, we acquired 32 bit data. We have several applications that work without problems. But now on the current project we have problem and we don't know why.

  When we create test signals and read them in the 6534 we have several failures, which means bits that are not read correctly. Because we have 3.3 volt signals and the 6534 is a 5V card, it was expected that the problem is there. But now we think that it may also be that we broke the real time.

  Parameters:

  -Data entry

  -20 MHz clock frequency

  -32-bit

  Does anyone know if the 6534 is able to acquire datas really up to 20 MHz?

  Thanks in advance

  Oliver

  Hi Marco,.

  During this time, we did an independent test.

  We have created an independent generator that sent a test signal 3, 5V and 20, 8 MHz and 32-bit to thePXI6534 and checked if the data are complete. We discovered, that there is absolutely no data loss.

  For us, this means that our problem is before the 6534 somewhere inside our electronics.

  In general, this means that the 6534 can handle 3, 3V signals to 20 MHz.

  Thanks for your help

• Problem: Using the command 'msg' with 'system Exec.vi.

  I try to write to the LabView code that takes advantage of the 'Exec.vi System '. For the moment, I have tried to use it to ping machines, return the command ipconfig and run through the code example that provides NEITHER.

  I would use the "msg" command used on Windows operating systems to send a message to several machines on our network at a time. Warning that we're about to update a program and that they should disconnect, things like that.

  I tried to use the command 'msg' LabView maintains return errors. I also wrote a quick command as follows file:

  @echo we
  CD c:\Windows\System32\
  Msg.exe /server:localhost * test

  When I run the batch of windows, it runs. When I launch from LabView (using the Exec.vi system), it fails.

  Potential quirks:

  I discovered in a different place under a machine to receive these messages they need to have a registry entry:

  "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server" and have a DWord value called "AllowRemoteRPC' = 1.

  Note that "/ Server: localhost" might be "/ server: anycomputer" and the "*" is used as a wildcard character that sends a message to anyone who is connected to this computer. Also note that the 'test' is the message to send.

  Any ideas why I'm having a problem?

  TL; Dr.: "System Exec.vi" does not have the command "msg". Why is this?

  
  

• New Member has exactly * a * problem for a long time with system! ***

  first of all, I want to say hello to everyone... I just registered today... actually I just discovered today these forums exist even ;^>

  Features: 6 months ago I bought a HP Pavilion a6600f... I love it and have bought things for her from the beginning... find it me easy to use and * beep * hard to turn off ;^> I always check to make sure that I have the latest drivers for everything, cleaning the registry, etc..

  I had exactly * one * problem for the last few months and it's bugging me enough now to do something.

  System details: the bureau a6600f Pavilion has a Pentium dual core E2200 clocked at 2.2 GHz... I put 4 GB of memory in it, and it runs Vista Home Premium w/Service Pack 1 (64-bit).  the rest is probably not important to this question.

  QUESTION: when I opened the health security & in the hp Advisor, I always have yellow exclamation in a triangle "PC Update," and also a exclamation point red in a square under "PC Health".  both are caused by the same problem... the fact that I continue to say there is a new version of the "HP health check' and I need to download/install.

  problem is that I can't do.  Here is what I get.

  at first, everything seems fine.  He considers it, download it (it's about 13 MB), and I get the message 'the active support HP library configure your new installation of the software.  * That's * where the problems begin.  I get:

  «HP Active Support Library error: Error 1316.» "A network error occurred while trying to read him comes from the file C:\windows\installer\HP Library.msi of active support" (note: I checked and I don't even have this file present in C:\windows\installer... that's the problem?)

  then I get "roll back the installation.

  and finally, "error:-1603 Fatal error during installation."  Consult the help of Windows Installer (msi.chm) or MSDN for more information"

  so I can't update the HP health check and I still have these two errors (the yellow triangle and red square) present in HP CAW - PC Health & Security.

  I searched these forums and found a few issues related to the CAW of HP, and I understand that some people even turn off... but it never gave me a problem outside of it, and I want to keep around if I can.

  I'm sorry if this post is on the long side, but I wanted to provide as much information as I could.

  so, my name is Michael King and I hope to be a regular contributor here, and I don' t mind if someone wants to email me, although I understand problems of this kind are better publicly displayed where they benefit from the community as a whole.

  Thank you

  first of all, I would like to thank the three of you who tried to help me with this problem.  This means that you, dmhoo29, anon, MrFixIt.  and as a gesture of goodwill, I would like to give Kudos to you, being a new Member and all three.

  you all had great suggestions, and based on these suggestions, I tried a few variations based on these suggestions.  Unfortunately, nothing has worked... She is always back to the same error messages, no matter what I did.

  In fact... HP * own * suggestion... which is essentially reproduced in this thread... does not work either.

  I had already spent hours on this ridiculous thing, and tonight I spent 3 hours on the subject.  I finally solved it, and the solution may benefit others who I see can easily run through a similar problem with other improvements... BECAUSE THE PROBLEM IS A RIDICULOUS OVERSIGHT ON THE PART OF HP that we can correct easily manually.

  THE SOLUTION

  What annoyed me early on, was the fact that I kept getting the message about the "HP Active Support Library.msi" file, which was looking for the installer in C:\Windows\Installer.  It seemed to me that the real problem was that he was looking for a file that simply wasn't there.

  Well, during my hours 3 screwing around with tonight, guess what I found?

  There's a right called "swsetup" subdirectory under the root of the C:\ drive.  and inside C:\swsetup, I found the following two subdirectories:

  C:\swsetup\sp36082 - and -.

  C:\swsetup\sp41377

  I knew of the many, many times I tried update HP Health Check that he was downloading sp41377. (don't remember the extension) via FTP from HP.  so I checked what was in C:\swsetup\sp41377 and guess what I found?  Well, a few things, but the only thing that concerns us is (drum roll please) THE FILE "HP ACTIVE SUPPORT LIBRARY. MSI!

  simply, I opened another window, surfed to C:\Windows\Installer and drag-and - drop "HP Active Support Library.msi" here (I pressed the 'Ctrl' key in order to make a copy of it rather than a civil rights movement).

  so now I had this annoying file in the right directory.  so, since my C:\swsetup\sp41377 window was still open, and since there is a file 'setup.exe' in there, I ran it.

  and the Holy Mother of God, it has actually worked.

  which means that what had happened was, when I tried to update the health check, that would create a subdirectory in C:\swsetup... in this case the C:\swsetup\sp41377 subdirectory... all he needed for the update here... and then ran "setup.exe" dump...

  . . except that the HP person who wrote 'setup.exe' forgot to include an itty-bitty statement in the code...

  to copy 'HP Active Support Library.msi' in the C:\Windows\Installer directory first.

  then pay attention to that sort of thing, my friends... If you try to update this HP wrote and that you get a 'cannot find file such and such in such and such directory' type of error msg, see if you can locate on your hard drive... maybe in C:\swsetup, perhaps elsewhere, I know... and if you find, just manually copy it in the required directory and run Setup again.  This might be the only time where HP committed this Sin right; ^ >... or even once, it cannot!

  Bravo and thank you again to all who have contributed.

• Use of Internet reporting real-time bandwidth

  Need advice with regard to the selection of software and the physical layout. I was invited to present reports on the use of the internet;

  -IP address

  port/protocol

  -bandwidth

  We havcusco cisco 4500.

  Our ISP router's router 3400 metro (fiber to Ethernet media converter).

  We have the ISP that is connected to a port on the 4500 in vlan 99, users are in vlan (using a gateway to virtual layer 3) 44.

  If I want to make just a quick capture could I just simply connect a workstation with wireshark to a port on the 4500 and place this port in vlan 99?

  If so I guess that the same theory would work with the tool as bandwidthD which is best suited to long term capture and has a nice pretty GUI for my manager?

  Bit confused as to whether I need a mirror or span port configuration.

  Thank you

  You need to configure SPAN with VLAN 99 as a source and the port that your workstation in question is connected to the destination. Otherwise most of the traffic will never reach the workstation considered.

• I want to use a chart of real-time-drawn arrow in Premiere Pro (a bit like the Tarantino style).

  I created a graph of arrow in After Effects, and I want to import into Premiere Pro to cover a precise shot to point AT something. The problem is, after I made the chart after affects and import it into Premiere Pro, the arrow is there but the graph also includes the solid square color background. I don't want the background. I want just the arrow, so that I can ask on a whim. How can I do?

  Make some AE by using a codec that supports alpha channels.  I like Quicktime movies in the Animation or PNG codec for it.  RGB + Alpha, Millions of colors + and straight (i.e. NOT premultiplied).

  Use the rendering queue.  Do not export.

• Command line of WinRAR with system Exec.vi

  I'm trying to code a program that will RAR a a folder that contains many subfolders with files in them.  WinRAR allows for codes of the command line to send to the WinRAR control via the command prompt (I have it works well).  What I want to do, is to integrate a vi of this code of command via the command prompt line.  I tried to use the Exec.vi system, but with very little luck.  I put the path for winrar tools to attend this repertoire and I used the string "cmd/c" before my entry so that LabVIEW knows that it is a DOS command.  I get an error message that says "'winrar' is not recognized as internal or external, command an executable program or batch file."  I tried to move the codes of the command line at the entrance standard and even winrar on this entry code as well (this one leaves the "cmd/c" as the command to send), still no dice.  Any suggestions would be most useful.  I can provide my code and a list of codes for WinRAR command line if you need it.  Other zip programs would be another option to take that I am open, as long as it can be controlled in the environment LabVIEW and the compression is the best.

  Thanks in advance!

  smercurio,

  Thank you!  It really worked.  What I had to do to get this working was to modify the command enter exec system vi.

  This is what it looks like:

  Thanks again!  This will save a lot of time for me!

  The great thing here I learned was the removal of the cmd /c for this.

• Application errors of the RT with the PXI-4461 with Labview real-time 9.0.1, DAQmx 9.0.2

  HI -.

  I recently converted a PXI time system real OS (PXI-1042 q chassis, controller PXI-8187, DAQ, PXI-4461, DAQ, PXI-6259). I can write and run DAQmx applications in real time with the 6259 very well. Whenever I try to write a labview RT app to use the 4461, however, it will fail. Note that I can use two cards through MAX I tried switching card slots, just in case it was a problem. Both cards worked with labview, the PXI chassis was before Windows.

  Attached are pictures of the screw base demo I built to show the problem. Since I was a mistake (-200758) if I started from the raw strings, I tried to create a MAX task and use it. The task, but he complained of a buffer is too small. I explicitly put the buffer to work around this problem and still get the same error (-200608). I've also attached a screenshot of the software currently on the Max MAX RT PXI system is version 4.6.2 btw. (I installed the most/all this from DS1 Dev Suite 2010 version).

  Please let me know if I hurt something installed, versions if 4461 just don't play nice with the new BT or RT software, or if something is wrong. Thank you.
