Missing reference to task DAQmx

• Create/edit task DAQmx vs DAQmxCreateTask

  I just started using Labwindows recently, so I'm a newbie here. You have a configuration great forum and I hope you can help me with that.

  so, as the title indicates what is the difference between the use of these DAQmxCreateTask(), the functions LoadTask() and manually create a DAQmx task using the menu 'tools '.

  Don't they realize the same thing? What is the need for each of them to be here? Am I missing something?

  I have already a little used in Labview. In that, to acquire data, we must use the icon tasks DAQmx to acquire/generate anything. but it is not all available such alternative programming, if I'm not mistaken. so, what's the problem with Labwindows/CVI then?

  Tools > generate DAQmx task launches a wizard that allows you to define the characteristics of the task and create the corresponding code. You can do this by yourself by manually writing individual instructions: this can be useful if you already have an existing code that you can reuse with adaptations little or if you have a special need that cannot meet the wizard or simply if you have the habit of writing code rather than rely on assistants which is my option.

  LoadTask is used to load a task created in MAX and use it in your program. This allows a form of customization of the task without changing the source code, with the obvious caveat that excessive changes in the task can cause the end behavior or abnormal length of program errors.

  All these options are legitimate ways to perform the same operation, a task for the acquisition of coding: know the characteristics of each of them, you can choose one that is most suitable to your purpose and your programming habits.

• How can I get a graphic display in real time of a task daqmx

  Hello

  I have set up a task DAQmx using the DAQ assistant and the task is to work and produce a graph/data, but not before the task is complete. How can I get a display in real-time of the numberical values or graphics?

  Any help would be really appreciated

  Thanks, Paul

  I used the DAQ assistant and labview is completely new to me, if im not sure where it take it from here.

  Then you should use a chart - not a graphic. A graph has a story. You must set this. Right click and select "Chart History Length".

• I 200918 error when you try to save a task DAQmx

  I have a Labview application 7.0 that creates and registers a task DAQmx (DAQmx version 8.0).  I can create a new task, but when I try to save the task I have Labview 200918 internal error. So far, this has worked very well on several machines but recently received this error message on a new Windows XP SP3 machine running.  I am able to create a backup task by using MAX (version 4.3).  Anyone know this kind of error before?

  Kind regards

  David

  This code corresponds to what is now an external error code.  The text of the error is:

  "Global channel name specified is already used for a task in the area of data.  NOR-DAQmx does not support global channel names and overlapping tasks.  Select another name. "

  I don't know why this code appears as an error internal to you, but the new text of the error, you should get going.

• Clear any open task daqmx

  Hello

  I was going crazy, because all of a sudden a tasks analog output did not work any more he said it conflicted with another task "always active"... I searched my entire application. Could not find anything. So finally, I closed the application labview together, and then it worked again, as if by magic. I came to the conclusion, that my stop and and clear task was not called when I closed my program in a different way.

  So my question: is there a possibility to see what daamx tasks are active when you start your program, so that you could erase any existing task?

  Kind regards
  Thijs

  Better yet, DAQmx tasks really need to be created once, preferably during development and no runtime if you can avoid it at all the.  Presist them to the project (if you are deploying in a debug environment) or, for MAX, if you deploy a exe.  It also allows your tasks be available for troubleshooting and integration, or even a FPS "Engineering" for the station.  I don't remember the last time I've delivered a solution the DAQmx encluded create Task.vi.

  Its pretty easy to write yourself a little utility to give up and cancel all tasks DAQmx.

  

• Convert from type string to type task DAQmx

  Hi all

  I would like to know if it's possible to convert type string DAQmx type (task DAQmx in)

  Thank you!

  This error is not associated with the conversion of the string type. I don't really know what is happening in your application, but I suspect that you are getting the error because you have not configured/registered your task properly, possibly in another application on the same system. I saw this problem before when functional using globals to save a task in one application and then read the overall task of the functional by using an another VI. This usually occurs because the functional world will save the value associated with the particular task. I would recommend that you look for the error code on the website and have a look at the following article. I apologize, but my knowledge is limited on this error.

  Recorded by program channels, NOR-DAQmx tasks and examples of scales

  TonP, I was avoiding the point of constraint

• Verify that a task DAQmx is a particular type of task

  I'm trying to find a method in LabVIEW to make sure a task DAQmx contains a particular type of task.  For this particular application, I want to check a task DAQmx is a digital output (line) before you run it.

  Regulate a DAQmx control i/o filtering is an option for me, but this code will be used by other programmers and I would like to add this check additional w / error handling in the case where the task is to be of the correct type.

  Thank you for your comments.

  -Nic

  Use the property of channel-> node property of Type string and it will tell you what type of task.

• Windows 8 does not not log on screen, all black dekstop, explorer.exe, disc missing from the Task Manager

  Hey. I am a newbie in this forum. And I really like to make my PC more 'me' even though my parents and brother told me that my PC did not differ from how difficult. But, I still like my PC... ^ ^
  But my PC encountered a problem in my birthday (March 8, ehehe just FYI). Its a terrible birthday gift: (...) Oh, there. Its all started when I accidentally install a skin pack or win 7 in my PC 8 victory. There is nothing wrong with installing proggress except a notification which inform on win 7 Starter has not installed correctly. :( Well, I ignored, first. But after I have it reboot, my dekstop went all black but it still can open the Task Manager. And then I try the system restore. It did not work properly. The only thing made worse. Somehow, my "(le seul compte dans mon PC) DELETED account." In fact, the log on screen consist only of the ease of access and power button with backgorund optomistic. Where are the data of the user, I mean a place where we inserted the password? XC its make me super bad mood. And after some restoration system with various restore points, I restarted my PC in safe mode successfully. Yippie, its worked perfectly in safe mode. I created a new account in safe mode. I thought that my problem more but no. and the bad news is that there is only one user account (a new one) in the journal on the screen! It'll be better I have the new account very well work, but it didn't! The dekstop always all black with no taskbar and it's the same problem as the first.
  I am not really confusing. What should I do? Should I remove a skin pack safe mode? or reinstall win 8 in PC COUNTER? Or do something that you already know the guy?
  Help me. I am so irritated by this problem. In any case, I want to ask one last thing, you prefer something after me or just think it was a charitable organization? Well, I just want to know. And I'll do my best to show my appreciation once you help me. I am so TROUBLED even if today is my birthday! I want a big anniversary with neither party. But its seems no big birthday. Please, help me. His will probably be my MOST BEAUTIFUL GIFT to a person who I know in internet. If you need something detailed about my problem, ask me. I need your response. :") SURE ME MY CRAZY MOM, IF SHE KNEW IF I AM WRONG IN MY PC AGAIN.

  Oh, there. The explorer.exe does not start in normal mode, but it works fine in safe mode. Also, I discovered that the disc is missing from the Task Manager. :) Help?

  Wish you a very happy birthday, Damaris.

  Of course, I can understand the situation you're in right now, and it's a shame. I will be happy to answer your query and try my best to offer my help as a gift for your birthday.

  Let me ask you;

  1. What happened when you tried the system restore?
  2. What was the last time that the computer worked well?
  3. What security software is installed on the computer?
  4. Remember to no particular change in the computer before the show?

  The issue may be due to any dispute of third party software, virus or any system or missing files / corruption. Let's try the methods below and check the status.

  Method 1: Since you are able to start the computer in safe mode without any mistake, I you suggest to start the computer in safe mode and then perform the clean boot to avoid software conflicts.

  Step 1: Start the computer in safe mode (as you are able to start the computer in safe mode with the steps you tried).

  Step 2: Perform the clean boot

  To help resolve the error and other messages, you can start Windows by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  Put your system to the clean boot state helps determine if third-party applications or startup items are causing the problem. You must follow the steps in the article mentioned below to perform a clean boot.

  How to perform a clean boot in Windows

  Note: see 'How do I reset the computer to start normally after a boot minimum troubleshooting' to reset the computer starts normally after troubleshooting.

  Method 2: Run Microsoft Safety Scanner

  The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

  Microsoft safety scanner

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  Note: Data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

  Method 3: Run the tool File Checker system in case where any system files are missing or corrupted.

  System File Checker is a Windows utility that allows users to find corruptions in Windows system files and restore the damaged files.

  Enter in the right edge of the screen and then click on Search. Or, if you use a mouse, point to the corner bottom right of the screen, then click on Search. Type the command prompt in the Search box, right click invite, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.

  At the command prompt, type the following command and press ENTER:

  sfc/scannow

  Note: Not close this command prompt window until the audit is 100% full. The results of the analysis will be posted when this process is completed.

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

• Missing reference OR for transmissions TDS2014?

  Not too sure if this is really a question for the forums OR or not, but I'm now getting a compile error that says 'method or data member not found' in my VBA program. The program is supposed to collect data from an oscilloscope TDS2014 transmissions through a GPIB-USB-HS, who did it in the past on the same computer, I am currently working on the program (it had been reformatted in the course of the past year). I get this error whenever I get a "call VISA. TVC. Command XXXXX", which leads me to think that I might be missing something of OR.

  For what it's worth, I am able to manually collect data and screenshots of the oscilloscope via OpenChoice Desktop of transmissions, and it is listed under the GPIB-USB-HS device as an instrument of measurement and automation. I TekVISA control listed as a reference in the program, and I have installed the latest versions of IVI Compliance Package, the driver for TDS2014 (from here) and TekVISA IVI.

  Any ideas?

  
  

• Signal saturated in a task daqmx without wiring

  Hello

  I installed driver-daqmx on an SMU-8108 controller in order to acquire analog signals of several load cells. The task that I created used to work until I started to use an FPGA card to perform other tasks in the program.

  Now, when I start my program, the output of the load cell is always 10.45... Volts, which means that more of the 10V output possible. There is no drifting but just a signal "saturated". Because I haven't found a bad wire, Earth or something similar, I have no other idea what could cause this signal problem.

  Thanks for your suggestions.

  Hi Henrik

  I use a block of connection of the SCB-68 (R series). The amplifier output signal (see attachment) is connected to the AI + and HAVE pine trees (68 # and #34).

  I added a resistance 100kOhm between HAVE + and I-ground and ground - HAVE and HAVE. It seems to work. Interestingly even resistance 100kOhm between HAVE + and HAVE ground seems to be enough...

  Welcome and thank you very much

• Close task DAQmx freezes

  Hi all

  I've been struggling for some time with the following problem, no relevant answers to it. Maybe someone here have met it before.

  I wrote a program in 2011 Labview data acquisition, using daqmx 9.3 + acquires data from a card NI 6008. The program works very well at all works with my laptop, but crashes during like every third performance on another laptop. Both have win7, the other is 64-bit (I'm not sure that matters).

  The program itself is quite complicated, so here I PASE a image of one of the parts he tends to freeze at (there are many other acquisition tasks, where it delimits to freeze, but every time that the structure of the block diagram is basically the same, with the creation and closing of the task). It is freezing more often when there is continuous sampling frequency of 1000 Hz and simultaneous treatment (trace, fft, etc.), in a regime of producer/consumer. The interesting thing is that it does not ALWAYS freeze.

  Whenever I check if the program hangs at the TASK.vi STOP without sending an error message. I can produce the same error with the simple example, I have insert below, if I run the program several times (it takes 10-20 tracks of stick to stop task.vi)

  Please, send any suggestions on what could be the problem.
  Another tip is the MAX itself gives an error of "embedded memory overflow", several times at startup. However, I tried the solution with the property node - without success.

  Dear Buadam,

  The workaround you mentioned has been implemented in NOR-DAQmx 9.4 and should be available from this version. The default value of value certainly not 1, since that would limit USB flow considerably, especially on faster devices.

  To explain more in detail: this property ("Analog Input" General Properties"Advanced" transfer of data and memory"County transfer USB) is responsible for defining the size of a USB transfer burst. The default USB transfer size is 32 KB. For a very fast channel or high County applications increases the size of USB transfer request are likely to increase flow. In this case however, we are voluntarily reducing the size of the transfer, to be absolutely sure that the bug in Windows 7 (how the system handles applicants on USB 2.0, specifically, how the packages are split) does affect us, resulting in deadlock as you packages known. So the idea here is to small enough packages to ensure that the USB driver is unable to divide, this prevents in turn also USB performance, but since the 6008 is a relatively slow, low peripheral County channel, we always have more than enough bandwidth.

  So, to summarize:

  • Please update on DAQmx 9.4 or more if you can (LabVIEW 2011 is supported up to the most recent, version 9.8)
  
  
  • I also recommend to upgrade the USB drivers from the laptop from the website of the provider as appropriate.
  
  
  • Set the AI. UsbXferReqSize to 1 once available. If you don't find it, try right-clicking on the property node, select filter... > display all attributes

  crossrulz: you have effectively reason that a finite measure stops the task once all samples have been read, so a wait until I recommended is redundant here, as it is expected to return with fact = True. The reasons why I suggested to use are:

  1. To refresh the status of the task, "check" that he has been arrested properly.
  
  
  2. To give the device of the extra time before the command stop the task/Clear task is sent.
  
  
  3. To catch errors that are stored in the DAQmx object, but not covered by the read operation, before attempting to stop/clear.

  Hope is makes sense.

  Kind regards:

• CDAQ line internal uses as to task DAQmx

  Hello

  I have a cDAQ-9178 and I would send a trigger to two different tasks (DO and HAVE) to be sure that they start at this very moment.

  I want to pull the trigger using the software instead of and the external trigger on PFI lines for example. For example, I would activate when a user a press control on the front panel.

  I tried to use the internal counter of the cDAQ (_ctr0) by producing a pulse on this subject. The problem is that I don't see these online when I'm the trigger of the 2 previously mentioned for task configuration. There are a lot of different line which seems to be possible to take, but I don't know how a trigger on the thesis...

  Help would be appreciated!

  Thank you!

  Is there any installation work you can do before generating a start trigger.  For example, create a task, creating channels, configuration of timing and call back to this subject can take a few hundred milliseconds.  There are intermediate steps, you can take in front-loading from time to time configuration.

  A DAQmx task has a certain number of States.  When you call start on a task, it passes through verified, reserved and committed to started.  So if you're explicitly your task, your call will be faster because your hardware is already configured.  If you had already created the task, created channels, set up the synchronization and committed to the task (via the DAQmx task control interface), the start task could take only 10 ms or more.  These numbers are on the top of my head.  This will not reduce the time it takes to start your task, only a specific stage of the issuance of your trigger for starting the software.

  That said, if you go to the road to counter, you need not to do for your tasks to AI and.  Just make sure you start them before your task to counter.  You could do what I described above for task of yoru meter if you feel he was taking too much time to generate your trigger to start.

  * Edit *.

  I should mention that the delay time that I was talking refers only to the time of when your user requests a trigger to start generating chassis a.  The time of your trigger from start to the first sample clock in your task is essentially nothing - about 12.5 ns or so depending on your configuration.

• Recovery task DAQmx

  Due to failed hard drive, I need to migrate not exported DAQmx tasks from one computer to another. Because of the same problem with a disk hard I can't open DAQmx and export these tasks - windows-based system is out of service.

  Does anyone know where DAQmx retains its tasks? Should what files I use to store the default tasks?

  I can recreate it on the new computer. I just need to know what they are, what cards and IOs they use.

  Hello arhangel123.

  I think that the information you are looking for is in this knowledge base article:
