From: scharkha on 30 Jan 2006 17:41 Hello I am new user to LabVIEW and I am using the LabVIEW 7 Express ( Evaluation Software) to learn more and see if we can use this in our research group. However, when I got to section 4: Acquiring Data and Communicating with Instruments, I got stuck. 1) I can not find the Tutorial " Taking an NI-DAQmx Measurement in LabVIEW 2) I can not find the DAQ Assitant in my output palette. Can some one help me plzzzzzzzzzzzzzzzzzz
From: Kurt NI AE on 30 Jan 2006 19:40 Hi, 1) Go to help drop down menu in either block diagram or front panel > Taking an NI-DAQmx Measurement in LabVIEW: In this tutorial, you create a voltage measurement task using the DAQ Assistant. You can manually navigate to this on your system at C:\Program Files\National Instruments\LabVIEW 7.1\help 2) With LV 7.1 the DAQ assistant can be found on the block diagram > right click > functions palette > input sub-palette or output sub-palette. (The DAQ Assistant will require NI DAQ MX driver to be installed.) The driver can be obtained for free at <a href="http://www.ni.com/downloads" target="_blank">www.ni.com/downloads</a> > drivers and updates link > multifunction DAQ. You may need to either reinstall or obtain a proper copy of LabVIEW. Kurt
From: scharkha on 30 Jan 2006 20:10 Hello kurt Thank your for your quick reply to my question, However, it did not work :( and It seems like I have some other problems. I have installed the LabVIEW 7 Express on my machine. as I mentioned it is a Evaluation version. ( v7.0) I also installed the NI-DAQmx Base on this PC. My major question is this: In order to run this tutorials, do I need to have my DAQ card installed on this machine as well ???? or the tutorial is not related to the the DAQ card. 1) you told me I should see the : "Go to help drop down menu in either block diagram or front panel > Taking an NI-DAQmx Measurement in LabVIEW: In this tutorial, you create a voltage measurement task using the DAQ Assistant. You can manually navigate to this on your system at C:\Program Files\National Instruments\LabVIEW 7.1\help" When I open a new VI and go to help, I do not see this option under it. I do not see any turorial uner that. 2) Also, I see foler with the name of lab view 7.1 but there is not short cuts to that so I am not able to run that.( all I can run is the 7.0 evaluation version). What am I doing worng??
From: Kurt NI AE on 31 Jan 2006 04:40 Hi, Beware: NI DAQ MX "base" and NI DAQ MX are different drivers. The DAQ Assistant is an Express VI (has a light blue background colour) and is therefore easy to use because it presents you with dialog box when you place one on the block diagram to allow you to set the vi up. The DAQ Assistant is built around the NI DAQ MX driver and so you need to have the NI DAQ MX driver installed to be able to use the DAQ Assistant Express VI properly. LabVIEW Version 7.0 Express will have DAQ Assistant but i believe anything prior to that release does not have daq assistant express vi.

Hi Scharkha- The tutorial you're looking for is located under "C:\Program Files\National Instruments\LabVIEW 7.0\help\daqmxtutorial.chm" for a LabVIEW 7.0 installation. In order to use the DAQ Assistant you will need to install the <a href="http://digital.ni.com/softlib.nsf/websearch/4C9E45F6EE5C29F98625708900712CBC?opendocument&node=132060_US" target="_blank">NI-DAQmx 8.0</a> driver. It would perhaps be more informative to use a physical DAQ device when you are working through the tutorial, but it is not required. You can use NI-DAQmx Simulated Devices (see <a href="http://digital.ni.com/public.nsf/websearch/75CF478A58545DFC86256FCC006E25A2?OpenDocument" target="_blank">this KB</a> for more information) to simulate most of the funcationality of a physical DAQ device. Hopefully this helps- |
