Daqmx control task

我的情況是: 在開師兄的LABVIEW 檔的時候.發覺要搜索很多未知的檔案,
例如 daqmx control task.vi
DAQmx start task.vi
我想問這些檔案可以在那裏找呢????

你應該是沒有安裝NI-DAQmx
你可以連到以下的網站下載：
http://www.ni.com/nisearch/app/main/p/bot/no/ap/tech/lang/zht/pg/1/sn/catnav:du,n8:3478.41.181.5495,...
最新的版本為NI-DAQmx 9.2.2
建議安裝前先確認使用的Labview版本
然後打開readme.html 找尋是否該版的NI-DAQmx有支援所使用的Labview版本
例如在NI-DAQmx 9.2.2支援Labview 8.5.x, 8.6.x, 2009, and 2010

Cannot find daqmx control task.vi after upgrading computer, OS and LabVIEW

Hello,
I have recently upgraded both my computer, OS and my LabVIEW version and I am having some issues.
My old system was:
LabVIEW 8.6 Professional Development System running on Windows XP SP3 (Dell Desktop computer)
My new system is:
LabVIEW 2014 SP1 Professional Development System running on Windows 8.1 Pro (MS Surface Pro computer)
I did a clean install of the LV 2014 which went smoothly. I then copied my old projects from the old machine to the new.
The simpler projects load without problem.
Some of the bigger project begin loading but hang on "Find the VI Named "DAQmx Control Task.vi" which does not seems to exist on the new computer.
There are several other DAQmx VIs that the project loader wants and do not appear to exist on the computer also.
I'm guess this could be because of the new OS, new LabView version, or because the new PC is a "tablet", or some combination of those?
Any ideas?
adTHANKSvance,
Bob

Hi bob,
when the old PC could load these VIs without complaining abut missing DAQmx functions it had DAQmx installed. Point.
Start the DeviceDriver DVD and install DAQmx.
Hint: Whenever you want to replicate your LabVIEW installation on a different computer you should check the "Software" section in MAX. It will list all needed parts/toolkits/drivers you have installed!

下载了DAQmx9.0,为什么找不到" vilib :\DAQmx\configure\task.llb\DAQmx Control Task.vi"等一些VI

下载了DAQmx9.0，但是在打开如SVL Calibrate Sensor VI时，为什么找不到"<vilib>:\DAQmx\configure\task.llb\DAQmx Control Task.vi"等一些VI

我的找不到DAQmx Configure Logging 这个VI

DAQmx Cotrol task

Dear ALL:
目前我是使用DAQmx, 配合PCI-6052E輸出訊號
其中輸出的訊號必須要能夠切換訊號的頻率, 振幅, 相位等
目前很有問題的地方在於不同頻率或振幅相位間的訊號做銜接時
無法順利銜接造成輸出的訊號到元件上時會產生許多問題,
目前想到最基本的方法是每一個訊號在完整輸出或者輸出訊號的振幅到0的時候切斷
並接著輸出下一段波型,
因此想到了DAQmx Control Task 這個Icon,
可是我使用了之後卻發生了
Error -200479
DAQmx Control Task.vi:2<append>
<B>Task Name: </B>_unnamedTask<2BA>
因此想在此請教一下:
1.此錯誤的發生該如何解決??
2.除了我目前使用DAQmx Control Task之外有其他的方法可以嘗試嗎??
PS1. 軟硬體使用LV 8.2, DAQ 9.0, PCI-6052E
Best Regards

Error -200587 occurred at DAQmx Start Task.vi:7

I am running the attached code Merrit_Coil_calibration, and I get the following error:
Error -200587 occurred at DAQmx Start Task.vi:7
Possible reason(s):
Requested operation could not be performed, because the specified digital lines are either reserved or the device is not present in NI-DAQmx.
It is possible that these lines are reserved by another task, the device is being used through the Traditional NI-DAQ interface, or the device is being reset. You might also get the error if the specified resource is currently in use by LabVIEW network variables bound to the DAQ Channel, or if the DAQ Channel is being used in any OPC Client software.
If you are using these lines with another task, wait for the task to complete. If you are using the device through the Traditional NI-DAQ interface, and you want to use it with NI-DAQmx, reset (initialize) the device using the Traditional NI-DAQ interface. If you are resetting the device, wait for the reset to finish.
Device: Dev2
Task Name: _unnamedTask<F>
I am calling the same DAQ, many different places in my code and I think that is the problem, but I can not figure out why or hw to fix it. Anyone have any suggestions?

Thank you both for your input. I slightly changed my code to Merritt_Coil_calibration (updated code attached) and the first error went away, but now I have a different one which is:
Error -200429 occurred at DAQmx Write (Digital U32 1Chan 1Samp).vi:1
Possible reason(s):
Value passed to the Task/Channels In control is an empty string (or I/O control).
The value must refer to a valid task or valid channels.
As far as what DAQ device I am using, it is the NI USB 6009. I am only using digital port 0. During different pieces of my code I send different values to port 0. I am using this to drive some stepper motors. I thus send square waves on the different pins on port 0. I do not know if this is exactly what you were asking.
Whatever the case, I was wondering if anyone knows why this error occurs and how I could fix it.
thanks.

How to get "Browse" list of any DAQmx control in array form

When any DAQmx control is pulled down, it gives Browse option in the list as well along with a list. On clicking the Browse button same list is displayed in another dialog box. Is there any way to get this list in the form of an array or in any other form for further usage.

I actually want to get an array containing list of all physical Channels of all devices installed on a system. Just to choose one Physical channel one can use DAQmx Physical channel control. And when this control is pulled down it gives complete list of all physical channels of all devices intalled on that system but this control selects only one channel. One way to get that array or list is to put a propery node of this control in a loop which points to one element of that list and keeps shifiting to next element on every iteration but unfortunately there is no such property node.
The example which u have attached with ur message actually uses DAQmx System property node which gives an array of all devices installed on that system, similary this propery node also gives certain other lists like all Tasks, global channels etc but no physical channels and neither I could find any such property.
I hope u've understood my problem so if u could help me out I'll be thankful to u.

Missing DAQmx Create Task.vi among others

Hi all,
I'm trying to run a .vi made in Labview 8.5 using Labview 2012. I have the most recent version of DAQmx (9.5) installed, but it's unable to find the file DAQmx Create Task.vi, and if I chose to ignore it about 6 other files pop up that it is also unable to find. I have uninstalled and installed DAQmx on both my computer and two other computers running Labview 2009 to try and get this to work, but nothing seems to be solving the problem. Any ideas what might be going wrong here?
Thanks!

Are you trying to open the VIs using 8.5 or 2012? Are the DAQmx VIs in the palette?

How to remove channel from DAQmx create Task.vi

Vikas H. Kumthekar
ASE
Tata Consultancy Services
Pune-1

How are you using the DAQmx Create Task.vi? Are you using it to include a global channel or copy a task that was previously created in Measurement and Automation Explorer (MAX)? If this is the case the only way to remove a channel would be to delete the global channel or modify the physical channels for that task in MAX. If you are creating a new task you can use the DAQmx Create Channel.vi to specify the physical channels that you would like to include or exclude.

Error 229771 occurred at DAQmx Start Task - only in Labview project

Labview 2011 sp1
os: W7 32bits
DAQmx 9.7.0f0
ni-PCI 6251
Hi,
I'm working with a ni-PCI 6251 card. I got the error : Error -229771 occurred at DAQmx Start Task. Possible reasons :Internal sofware error occured in MIG software ... when I'm trying to launch my data acquisition vi. This error was already reported in this post :
http://forums.ni.com/t5/Academic-Hardware-Products-NI/Error-229771-occurred-at-DAQmx-Start-Task/td-p...
I tried to reinstall DAQmx as explained in the post but it unfurtunatly it did'nt fix my issue.
I've notice the following points :
1. This error appears randomly, after several reboots the vi will finally run without error
2. The error only appears when the vi is included in project
I will really appreciate any kind of help.

Where is DAQmx Is Task Done.vi?

I have a new Windows 7 SP1 x64 installation with LabView 10 installed. It prompted for one (32-bit) patch and I installed it. Tried to launch some third-party vi and it's gives me a prompt asking where is the DAQmx Is Task Done.vi?
From what I can tell, this vi should be builtin, but I don't see it anywhere in LabView directory (or at least Window search doesn't). What could be going on?
Solved!
Go to Solution.

Do you see it in the palette?
Meas IO > DAQmx > DAQmx Advanced Task Options > DAQmx Is Task Done.vi.
EDIT: Oop, I missed that "before Labview" part. dkfire is right, you must install toolkits AFTER LabVIEW or they don't know where to install their drivers.
Using LabVIEW: 7.1.1, 8.5.1 & 2013

Stand-Alone application with LabView 7.0 getting error can't find DAQmx clear task.vi

I have attempted to create a stand alone vi with the Build Application or Shared Library(dll) in LabVeiw 7.0
When I put it on another PC to test it I get the error "can't find DAQmx clear task.vi"
the other PC has Labview 7.0 and DAQmx 8.1 also.
I believe my problem is in the source tab where you are supposed to add support and dynamic vi's I have search the forums and Ni's data base and have not found a solution.
Solved!
Go to Solution.

Hi LabTech09,
When you run the executable on the other computer is when you get this error? Do you have the exact same versions of LabVIEW and DAQmx on both computers? Does the dialog allow you to navigate to the DAQmx clear task.vi? If so, you can find these VIs in C:\Program Files\National Instruments\LabVIEW 7.0\vi.lib\DAQmx\configure\task.llb. Does the executable work on the development machine (the machine it was compiled on)?

Does performing a DAQmx Clear Task on a PCI-4474 card change the state of the IEPE current?

Does performing a DAQmx Clear Task on a PCI-4474
card change the state
of the IEPE current? If the IEPE current was on, does it remain
on even though the task as been cleared? If the IEPE current
remains on, then I assume I don't have to wait for the IEPE current to
settle if I make a new Task and start a new measurement--is this
correct?
Thank you in advance for your help.
Ken

DAQmx Clear Task should not turn off IEPE current. You will have to explicity set IEPE current to On (for that channel) whenever you use any of the AI channels on your 4474 in order to keep the IEPE On because the IEPE for all channels in the AI subsystem will be set to the default state (Off) unless explicitly configured. That said, if you clear a task that had IEPE On, and then initialize a new task and set IEPE On, the IEPE will be uninterrupted and there should be no need to wait for the IEPE to settle. Other components of your measurement system might need time to settle if their state was changed between tasks (DUT, sensor, AC coupling, etc.)

Does multiple instances of DAQmx start task result in error?

I am trying to read voltages from pressure transducers and LVDTs in two separate While Loops. But when running the program there is an error regarding DAQmx Start Task.vi. So I was wondering if multiple instances of DAQmx Start task results in error. I have attached the vi.
Thanks

Thank you for the reply. New to Labview so I didn't know that we had to search using the error code, I tried searching using text though. Will do that from the next time, thanks.
I do not have the problem with the write tasks but only with the read tasks. Right now I have one start task for all the input from the pressure transducers and LVDTs and three start tasks for the three analogue outputs and the program seems to run fine.

DAQmx Stop Task error -50550

Hi,
I'm occasionally encountering error -50550 while attempting to stop an AI Task; though its occurrence is sporadic:
LabVIEW Error Details:
Error Code: -50550
Source: DAQmx Stop Task.vi:3 Task Name: AllAI
Description: Error -50550 occurred at DAQmx Stop Task.vi:3 Possible reason(s): A synchronization object was not acquired within the time limit. The operation could not be completed as specified. Task Name: AllAI
The way I've currently written my VI, I'm creating an AI voltage task with a sampling rate of 1k and buffer size of 50k. I start the task use the daqmx read in a while loop until I reach a threshold, and then fall out of the loop and stop the task.
I'm using LabVIEW 8, DAQmx 8 on WinXP.
Anyone have any idea of the cause or cure?
Thanks in advance,
Glyn

Hi Glyn,
Unfortunately, I do not have many ideas about that error. Can you post the portion of your code that demonstrates this error so that I can try to see it? Also, how often do you see this error? It sounds like it is not every time that you run the program.
Thanks,
Laura

Pda daqmx base task information

Hi!
I use LV PDA Module 8., Windows Mobile 5 OS on PDA and CF-6004 acquisition card.
I configure 3 tasks in DAQmx Base Task Configuration Utility, which have different sampling rate and samples per channel property.
Problem is that I can't get this properties programmical, since PDA Module doesn't support Timing Node, so I have no information what sampling rate is set when I select new Task in my application.
Thanks,
andrej

Hi Andrej,
Since DAQmx Base does not offer property nodes or the waveform data type, there is currently not a way to programmatically check which sampling rate was used by the 6004. If you feel strongly that this feature should be included, I encourage you to create a product suggestion and describe your application in detail. R&D considers these suggestions very seriously when making decisions about future products. I hope this helps.
