• Emergency aid! How can I run in the same block diagram two separate labview codes each with a diferent execution timings?

  Dear all.

  I have 2 progrlams application in the same schema. the intention is to use the 2 different when excuting programs for different applications, and each have to stop and start button, of course, I'll have to stop master. But when I run the program, it works as a program in time, it's the 1st block which I make active only, when I tried to activate the second block, that won't work, works only when I stopped the1st one. So, he wants your help, how can I solve my problem. Here I am attaching some of my programs.

  Kind regards!

  Furthermore, if you want two loops to run at the same time, just this.

  

• NI LabVIEW driver for the SRS DS345 function generator generates error "(Hex 0xBFFF0011) insufficient location information or the device or resource is not present in the system."

  Hello

  We have a generator function SRS DS345.

  I just downloaded the driver NOR for the instrument on http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=E3B19B3E9149659CE034080020E748....

  After installation, the DS345 appears in MAX, and I can well communicate with him.

  However, if I run the srds345 to Started.vi, I get an error "location information insufficient (Hex 0xBFFF0011) or the device or resource is not present in the system" from initialize it with Options.vi srds345 sub - vi.

  The only change I did Exchange address GPIB 14 to 19, which is our function generator GPIB address. In addition, the

  Functions of SRS DS345 generator of function palette is empty, even after you restart LabVIEW (see attachment). I'm using LabVIEW 8.5.1.

  Your help in resolving this issue is appreciated. Thank you.

  Best regards

  Have you installed the driver from LabVIEW or copied directly from inst.lib?

  The first is easier, and you don't have to restart LV more...

  Error in a not filled gpib address points. I have not checked if this driver has a resource name visa or a string of gpib address old but in the first case, try the little triangle on the right at the slect address instead of by hand.

• Continuity of the functions of the basic function generator

  I would use the basic function generator to create a continuous waveform.

  im not sure if Im not run or use the function generator correctly.

  for each iternation of the while loop, I would like to only one point of the exit sinusoid.

  Then the next iternation would produce the next point in the sinwave.

  

  It seems to keep missing a few points

  I'm not sure why - this.

  It's hard to notice that if the plot is made only show few places for each sampling point.

  

  I'm fairly certain that that VI uses the current timestamp as the value of x, so whenever your computer receives a bit busy (I'm off / 0, etc.) it is likely to be a small problem.  You can always use the simple sinus with the number of the iteration (optimized for the desired period).

• Digital output frequency seems to be twice the frequency generated by the basic function generator

  Hi Labview forum,

  I wrote a program (attached) Labview to generate 3 PWM, square wave, signals that has the same frequency and phase delay right (so that when a signal is off, the other signal is lit. Then the next signal). Everything seems to work fine except that the frequency of the PWM signals generated seems twice as the frequency given to the basic function generator. Anyone have any idea why this is happening? Anyhelp would be greatly appreciated.

  Thank you!

  Totally agree with the advice of all GerdW than the hardware timing of your hardware DAQ will be much more reliable.  That said, part of what you are probably hitting is a little quirk of the primitive delay msec.   Requests for 1 msec have long been particularly little reliable (although they * seem * to have improved in recent years, probably due to the better OS support in Win 7 or something).

  I did minimal mods to your code with comments from you switch to a timed loop.  My quick test showed he is good enough to hit the 1 length of loop of target msec.

• Change the amplitude of the Agilent function generator output while the output is on

  Hello

  I am writing a program to scan the amplitude of a sine wave of a function (Agilent 33210 a) generator output. I have two sets of pilot example: Agilent 33xxx and HP33120a (the first one uses VISA, IVI 2 uses).

  Using the example of driver code, I changed to generate a sine wave to 1Vpp, wait 1 sec, and then modify the amplitude of 0, 5V. I have attached the images in my field that show what happens when I do that. The two examples cut first exit before Relighting with a different amplitude. 33xxx driver takes 140ms for change, and has a strange burst between the two signal. HP3120a driver takes 30ms and cleaner air.

  Agilent 33xxx example using:

  \

  HP33120a example using:

  

  

  I would like to have the change is instantaneous. When you use the generator manually, I can turn the button and change the output in real-time without delays.

  Thanks for the suggestion of Mateus, but I am trying to automate this process of my best. Change the VISA pilot is the direction I want to go.

  Thank you crossrulz... I wrote a new issue VI of the Standard waveform VI set up so that it simply writes the new amplitude control and none of the other things. Worked like a charm! Now the waveform changes amplitude without turning off the exit. I also checked to see if re-defining the shape of sine wave (even if the original is also sinusoidal) was the cause of the delay as you suggested, and you were right. Thanks for the help!

  

• Need to model for the XR-2206 function generator chip

  I'm designing a training tool for the operation of the basic oscilloscope and decided to use a function generator based on chip XR-2206. Is there a template for this? I know its old but...

  Hi jwaters,.

  Unfortunately, we do not have anything; However, perhaps it will be useful.

• Continuity of the functions of the basic function generator and the right time

  I need to create a sine wave, point by point, which will be forwarded to the MIP and finally to a channel of analog output on a PCI-6014

  Ive tried a few different ways to do it, but everyone has some problems with her slider.

  with the 'generator.vi of the base feature.

  and also the "sine waveform.vi.

  There seems to be problems with this lack of points.

  someone helpfully pointed, its very likely windows interrupts the origin of the problem

  Here is a schematic representation of the panels front and rear

  the back panel

  

  the façade has a few points that are missing

  

  Another way to do that seems to work better known that the signal "simulate" express vi.

  It's great because it's actually a way of sine 1htz occur at 1htz.

  There are also all the points.

  The problem is that as soon as I put in my request, she grinds to stop.

  Program speed about changes 10khtz less than 1htz when the basic function generator is replaced with this express vi.

  

  A third idea or concept that has been proposed is to put a programmer to slow the timetable.

  It is once again, works fine, no more points are missed in the plot.

  Yet, he kills again the speed of execution of the program as everything can wait 1ms (or the recripocal of sampling points interval time).

  

  Someone at - it an idea on how I can get a sine wave in PID, then, in the analog waveform without a huge amount of the efficiency of the program. Im sure this is simple.

  Nevermind

  accedanta do the 2nd option from the top.

  go just to increase the number of samples for now leave the rest of the fastest of the program

• #VALUE in Excel for a formula that uses a missing cell with the function generator

  Forum,
  
  When I use the function generator to retrieve data of HFM in Excel, I have a problem with the formulas using these data when it is absent.
  
  If I didn't put in the #nodata / replacement of labels missing, then SmartView puts ' "in the cell, which causes an error if I try to summarize with something else (= '" + 1,234.56 returns #VALUE).
  
  SmartView let me use me replacement value of 0... I have found a workaround using of.0 as the replacement value, but I guess there is probably a more elegant way to solve this problem.
  
  Let me know if you have an idea.
  
  Thank you

• Call the javascript function using parameters cause run an immediate dependant

  Hello.
  
  I saw a strange behavior, if I try to use javascript parameters in the method af:clientListener property.
  
  Using the syntax

   <af:commandButton text="Init" id="cb1"
     partialSubmit="true">
     <af:clientListener method="OnInitControl1" type="click"/>
  </af:commandButton>

  and javascript

  function OnInitControl1() {
    alert('OnInitControl1 called');
  }

  the method oninitcontrol1 is called first with the click of the button.
  
  But with the syntax

  <af:commandButton text="Init" id="cb1"
     partialSubmit="true">
     <af:clientListener method="InitCtrl('Control1')" type="click"/>
  </af:commandButton>

  and javascript

  function InitCtrl(frameName) {
    alert('InitCtrl(' + frameName + ') called');
  }

  the InitCtrl function is called immediately to the loading of the page.
  
  In both cases, the javascript file is inserted into the use of af: document

  <af:resource type="javascript" source="/ScriptHelper.js"/>

  Is my "method" of the af property syntax: clientListener the problem?
  
  Paul.

  Paul,

  I don't know if you can call javascript with parameters in the way that you are currently using. However, have you tried using an af:clientAttribute and enhance the javascript?

  Check the operating instructions by Frank on the related topic.

• NEITHER USB 6343 negative DC voltage after power function generator

  Hey all,.

  I'm having a problem with my DAQ.  I'll generate a square wave in Labview with a generator function and that the output to my DAQ.  The function exited through the acquisition of data very well; However, when the production is stopped, a negative voltage remains equal to the amplitude ("drawing" below).  This happens if I use the express VI DAQAssistant, or manually create the channel, generate the function and the function read/write on the channel.  This tension continues even after the VI is finished running.  The only way to get rid of it is physically cut the DAQ and turn it back on.  Any thoughts on why this might be, or how to fix?

  Start VI

  ____|____|____|____|____|____|

  ____|____|____|____|____|____| _ _ _ _ _ _ _ _ 0V

  ____|____|____|____|____|____|____________ - A V

  ____|____|____|____|____|____|

  End VI

  Tom

  I thought about it.  I had to add some more to the clock.  I had added a data point in the table of waveform which was written for the acquisition of data because the timer wrote n samples, instead of n + 1

  So, to recap: I pulled the table leave the waveform data, inserted a '0' at the end of the wave, reintroduced the data of Y in the form of wave and incremented to the timer of a sample (because I added a sample for waveform data).

• 29 Firefox fails to come out properly and continues to run in the Task Manager.

  It is a continuation of a thread found here:
  https://support.mozilla.org/en-US/questions/997448 by Compumind.

  I pointed out that I had the same experience, especially at the opening of the email links in Thunderbird. I reported also that forced me to go back to 28 FF.

  Moses responded by top wire and suggested:
  (1) download a fresh installer of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

  (2) the release of Firefox.

  (3) rename the folder

  C:\Program Files (x 86) \Mozilla Firefox

  TO

  C:\Program Files (x 86) \OldFirefox

  (4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.

  I followed these instructions carefully but no joy. When installing 29 FF, not only refused to leave (using "exit") and continue to run in the Task Manager up until I killed him after the opening of links in Thunderbird, but I find that he refused to come out after a simple navigation and links.

  Moses had asked that I didn't answer in the original thread, so I re-post here.

  In my view, that there is a serious bug. With Firefox 28... no problem don't except a minor that I have indicated here:
  https://Bugzilla.Mozilla.org/show_bug.cgi?id=1002089

  Yet once I am obliged to 28 FF, although I miss the nice interface and security patches, I need to have a browser that works properly. My wife never even saw the Manager of the tasks before so that's the problem.

  In addition, "guesses" made with this post, the only other thing usual outside that I do, is to have a security policy about cookies (accept by default... I make exceptions for cookies I want to keep and have several that are "allow only for the session.") I also FF the value delete history of navigation at the exit, but that takes a fraction of a second.

  I look forward to when this matter can be addressed successfully and I am able to use 29 FF (and out properly... I can't wait for my wife to follow all of these instructions and it often close manually in the Manager of tasks... or what I want to do this.)

  Good luck for all Mozilla projects. Having installed 29 FF twice and then back return 28 twice, I'll wait and see how this plays out. Please don't send me the standard "start in safe mode", 'restart with disabled modules', 'reset Firefox' stuff (the last time that completely destroyed my browser). I don't think that is what is happening.

  Moses added that there is a problem with the e-mail notifications passing by, so take your time, friends.

  I think now (temporarily) this bug or problem has its roots in "history leaving Compensation."

  I made the leap after a few game with 29 PortableFirefox and reading the blog post linked here:

  [https://support.mozilla.org/en-US/que.../997918#answer-566755]

  .. .and installed 29 FF on my previous FF28 on my box. I unchecked the "clear history on exit" which was only to delete my history, not cookies or anything else, cor - el. My setting should not accept cookies unless I make an exception. Until the FF developers find a way to do this is functional, I'll just have to manually delete the history.

  Furthermore, John99, you want to maybe privacy.sanitize.sanitizeOnShutdown set to 'False', not 'true' If you want to stop the automatic deletion of the history at the exit (attempt).

  I've been running for about 6 hours. without experiencing the bug 'suspended '. So, I can live with that for now until this bug is fixed. It should be fixed... browsers are supposed to be able to do things like that.

  On the other hand, I could find things go wrong... but so far I'm not having a problem.

  I for several hours and will let you know later if things change.

  Kind regards

• Satellite Pro 4600: Win2k with SP4 - cooler run all the time

  Hello

  last week, I bought a used Toshiba Satellite Pro 4600 PIII, 1 GHz, 512 GB of Ram, WIFI and DVD burner. Great machine so far.

  After that I changed the FAT32 file system to NTFS and reinstalled Win2K/SP4 cooler runs all the time.

  TaskManager says that "THOT_KEY.exe" uses up 99% of the CPU power. Disabling this service reduces the power of the processor and the cooler was quite, BUT didn't really helped - lots of keys does not work.

  I ran a few utilities to disinfect as Kaspersky, NOD32 etc. to ensure that Ia´ve not taken some malware.
  Should I try a bios update or change some settings?

  Any ideas?

  Thanks for help

  Hello

  AFAIK the THOT_KEY.exe belongs to the Toshiba Hotkey utility that controls the various key functions.
  If you disable this service, you will not be able to use the FN keys more.
  I m not 100% sure why this service uses 99% of CPU performance, but perhaps that it s not completely compatible with the W2K service packs. Where did you download this utility? I found it on the page of Toshiba Europe!

  In my opinion, you should try to reinstall the system again. This is probably the key!

  Good luck
