• 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.

• 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

  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.

• Can I create two tasks of IA using the same unit of data acquisition?

  Hi all

  Sorry for the question of gumby, but I'm new to all this stuff DAQmx, and I'm trying to understand how it all works.

  I use a USB-6229 with LabVIEW 8.6.1.

  I would use 30 lines HAVE to monitor 30 voltage remote signals.

  I would use the other two lines of AI to perform input voltage independent tasks.

  I tried to create and start the two tasks, but I get an error message when I try to start the second task.  He tells me that the resource is not available.

  What is the cleaner way to configure things working for me?

  Thanks in advance.

  -FB

  Hi diarmaede,

  You can only create one task to HAVE on your card. Read all your DO this card in a loop. You can divide the result and send it to different loops to work on it.

  It will be useful.

• 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

  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.

  

• After creating a task, it is not listed in the Task Scheduler Library.

  Hello

  I created a system task to the system log. It was supposed to send an email to me whenever the event is logged.
  After saving it, I wanted to get to the Task Scheduler Library, but it has not been listed. I tried to create the task again, but it is said that a task with the same name already exists. The event took place, and when I looked at the status of the task, it shows the name of the task with the result of success.
  How can I remove / edit the task when I can't? Help appreciated.
  Thanks in advance

• Missing reference to task DAQmx

  Hello

  I have just inherited code without papers of an engineer who has left the company.

  We use a USB-6008 to control a stepper motor and take a few analog readings

  DAQmx tasks received really useful names such as "TO 0", guess that's Digital Out"0  However when I look at the tasks of the unit, "0" is not present. ""

  The program crashes and complains of an error.

  Is there something I'm missing here?  Y at - it another way that a string that "DO 0' culd be associated a task DAQmx?

  Rgds,

  Sean

  OK, I had a legacy project open.

  Virtual channels are in the new project.  I was looking everywhere on MAX, but it was in the project correct throughout.

• 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 could get set the frequency of sampling and to give a regular change of output, but im looking to get this long-term data acquisition. For example, the graph changes everything but 1 - 5 get 30 minutes of data.

  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".

• 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

• 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.

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

• How to create a task that runs once a day, immediately after the opening of session?

  Hello, I'm wondering how to create a task using the Task Scheduler that runs once a day, immediately after I have logon.

  The reason is I want to use Bing Desktop to change my wallpaper every day. However, I just want to run the first time I start my computer every day, so it will change the wallpaper. By default, it starts whenever I have to logon. It's annoying, because I just want it to start once a day to change the wallpaper. However, using the Task Scheduler, I put only a trigger to start "at the opening of session' or"once a day." If I choose once per day, it runs about 5-10 min after I login, instead of logon immediately after. If I choose the two triggers, then it starts after each session.

  Basically, I just want the Task Scheduler to launch the program after the connection the first time I connect to the computer on any given day. How can I do this?
