• Labview crossbow help

  I downloaded Labview vi crossbow and I tried to run the sample of reading data and display Health.vi. I get the error message: error 8001 occurred generic reading Possible or the reasons: some or all of the samples were not available for some of the specified nodes. Can someone explain why I get this error message? Data is evident when I use MoteView. Thanks for any help.

  I finally understood what the problem was. I usually ran MoteView with Xserve running at the same time. He was tied up the virtual serial port so that Labview could not use it. I just made sure the Xserve process was not running in the background and it started working.

• Screw LabVIEW compatibility helps with NI DAQmx device does not

  I use an old application written in Labview 7.1. Please see the attachment.

  now I use the same software with NI 6221 (supported DAQmx) _so I installed NI DAQmx compatibility live.

  I use the unit as DEV1-by default.

  I can't select any channel to browse...

  Please help me

  Please see attachment

  Thanks in advance

  If you right-click on the control and select "I/o name of filtering", say the DAQ or DAQmx channel name? If she says no DAQmx and data acquisition, you have a traditional DAQ channel control and you will not get a list of channels available since you actually use DAQmx. I suspect this is just a limitation of compatibility screw and you will need to enter the list of channels manually until you make a clean break and use DAQmx features.

• New to Labview, need help. USB-6008

  Hi there, let start by saying, I'm totally new to Labview.  I have experience of programming in C, C++, VB etc, but never in Labview.  I thought that Labview is not much of a difference, but I was very wrong.  I went and bought the acquisition of data USB-6008 and downloaded the trial labview to explore and I am totally stuck and have no idea how to proceed.  I can start over again and probably learn all the basics, but I don't want to take too much of my time.  in any case, here is a description of my project:

  Configuration: USB-6008 - to measure the voltage of a battery lithium ~3.6V

  Circuit printed with a switch either connects the battery resistance or not.  the switch can be turned on and off by a USB-6008 analog voltage output

  What I want to do in pseudo-code:

  If you click START,

  Take a read of DAQ and shop to chart and indicator of voltage 1

  If the voltage is > 3.6, then

  30 seconds

  a voltage data acquisition to turn on the switch and light load lights output

  read DAQ and update graphic and indicator of voltage 2 reading

  If it is DAQ< 3.5,="" status="" indicator="OFF," else="">

  30 seconds of the end loop

  If the last reading after 30 seconds of DAQ is > 3.5, the message 'pass' else a message "fail".

  on the other

  indicate a voltage lower than 3.6V and stop the program

  end if and stop the program.

  NOTE: the voltage indicator 1 show ONLY the first reading before the circuit switch is on.

  I didn't know that it is very difficult to program, because everything is very basic, but since I don't know Labview, I do not know how to proceed.  a front is attached.

  Thank you for your help.

  Hello!

  To start, here are a few things.

  1. learning LabVIEW:

  www.NI.com/lv101

  This has all kinds of videos step by step based on LabVIEW and is a great resource just start... it's really great because you can click on a video about any topic that interests you. There are a set of tabs at the top that categorize videos.

  2 examples of DAQ. In LabVIEW go to the Help menu > examples of find... Then in the window that opens (this is called the Finder of the example) you can navigate to the material file Input and Output > DAQmx > Analog measures > voltage

  We have tons of DAQ examples, so this should at least allow you to read a voltage quickly.

  I hope this helps!

• Could not find 'STATUS' tool in LabVIEW; Need help!

  Hi all

  I am quite new to LabVIEW environment and try to learn more about LabVIEW. I'm running LabVIEW 2015 SP1 and is currently working on a project code example, which measures the temperature and the humidity in the room. Inside the code, I'm not so sure on a tool called 'STATUS' (see attached) and where I can find this tool in the version of LabVIEW 2015?

  Could someone please me where I can see this tool 'STATUS' by 2015 LabVIEW suggest? I have attached my screenshoot vi for your reference.

  Thank you so much for your insight in advance.

  See you soon,.

  Mineesh

  The thread running in the box called 'Status' is called the error line.  You can recognize the content of LabVIEW wires by their color and their appearance.  In particular, the color of this thread indicates that this is a type of LabVIEW called a 'Cluster', one of whose elements is called 'Status', a Boolean value (as you can tell by its green color).

  You need to spend time to learn a few basics about LabVIEW.  There are tools on the Web.  Here are some links to free training to help you get started...

• LabVIEW 2010 help control Source code...

  I'm trying to set up Tortoise SVN to work with LabVIEW 2010.  I was able to get lvmerge and lvcompare to work by adding them to the list of programs within the turtle, but leave in LabVIEW there is a section to configure the source control I have a problem with.  Under "Configure Source code control" there is a drop down to the name of the Source control provider.  There is only one option: < none=""> .  I looked into it a bit online and found that LabVIEW running in Windows searches the registry database for a list of the sources of control.  I don't know exactly what he's looking for in the registry, but maybe I could make an entry in the registry to get LabVIEW see Tortoise SVN.  Anyone had this problem or any experience with this?

  To use the NCC options provided by LabVIEW you will need from a provider. For subversion, it is possible with the PushOK SVN SCC plugin.

  If you install you can checkin/checkout directly from the LabVIEW project environment.

  If you really like TortoiseSVN discover the Tortoise SVN integration made by JKI-software.

  PS there is nothing special about 2010 in the integration of the CSC.

• I can't manage keithley 224 driver with labview. Help me, please.

  Hi, my name is Kim Yonghyun.

  I am student in physics at the University of Seoul.

  I use Keithley 224 Power Source.

  I would like to address with the LabVIEW (v2011) for the Keithley224 program.

  I try to use the driver provided by Keithley, but Keithley224 does not recognize the command.

  Active LED on GPIB-USB-HS does not even turn.

  V - limit, Source, timeout, none of the commands which are not get delivered.

  Here I am attaching the file vi provided by Keithley.

  If you need more information to resolve this problem, then please tell me.

  Thank you very much.

  Hello panda,.

  view a screenshot of your MAX...

  Under GPIB, you should see a list of devices connected (and turned on)!

• Possible bug in LabVIEW with help chart

  The attached VI reads a group of bytes as U8 from a file and writes the each other in a new file.  It does this by using the function array decimate.  It seems that there is a bug in LabVIEW.  If the '+ 0' is deleted from the code nothing but 0 is written to the file.  If you explore the table that will be written in the file it shows no null values, but the resulting file is always all zeros.  Addition of '+ 0' was a work around the issue.

  I'm under LabVIEW version 8.5.

  This looks similar to the LabVIEW 8.5 suspiciosly bug, we discussed quite earlier.

  Try placing a primitive 'always copy' (from the palette ' application control... control memory') until the file write and see if things improve. Good luck!

• LabVIEW Modbus HELP!

  
  

  You must look at the manual and to determine how the controller uses register set.  What I saw with Watlow for example, is that the registry is multiplied by 10, set point as the set point can have a decimal.  In your case, you must set the registry to 123 to 12.3.  I also saw that some values may be represented by two records, which represent the binary value.  Format is usually described in the manual.  You can try to read the registry and see if the value is meaningless as well.

• USB-6501 - impossible to find a basic example of Labview

  Hello

  I recently bought a USB-6501 card and I used it in my own succesfully end and C++ programs using the DAQmx drivers.

  Then I tried to move to Labview 2009 (I never used Labview) so I looked for a simple example.

  I tried to boot from the example 'interactive Control Panel' (http://digital.ni.com/public.nsf/allkb/AF0F31EE5D2AD23F862573140009D7C2?OpenDocument).

  I had to install the 'DAQmx Base' for him to start, as described in the previous link. now it begins (before Labview attempted to get a few missing .vi) but I get a message "error 200220 occurred at an unidentified locatio.

  Then I realized this example is 'old' (as explained here: http://forums.ni.com/ni/board/message?board.id=170&thread.id=209247), and it is suggested to look for a new one in example Finder ' entry-level equipment / output-> DAQmx-> Digital measurement (or generation)-> read Dig Port.VI.

  I tried, but along the way ' entry-level equipment / output-> DAQmx-> "only a folder named"Analog Measurement\Voltage"exists.

  Also in the search for 'Reading dig Port.VI' does not work.

  I've already spent many hours in this research and tent and the fact that I am not able to find not even a basic example, it is quite frustrating and it is making me give up the idea of using Labview.

  Please can anyone give me any suggestions where find/download an example simple and minimum to use my USB6501 in Labview 2009?

  Thank you

  Scipione.

  First, install DAQmx Base was a mistake. Uninstall it and then install the Driver-OR-DAQmx. The driver must be installed after the installation of LabVIEW. After installation, make sure that the device is listed in MAX under "DAQmx devices. If it is not, your installation is still not correct.

  To search for example LabVIEW, see help > find examples. Under Input and Output hardware > DAQmx, you will find the digital generation and numerical measures. You have to look at the simple, timed software examples such as read write dig Chan, writing Port to dig, dig chan, reading Dig Port. You also have the option to use the DAQ Assistant.

• use IMAQdx functions in Labview Communications System Design Suite

  Hello

  I would like to read an image and use the bytes obtained to perform certain functions. Currently, the system has Labview Communications System Design Suite (2014 SP1)

  and vision acquisition software installed. I don't know how to use IMAQdx features in labview.  Can anyone help?

  Thank you!

  I do not work with the Design Suite of Labview Communications System.

  In LAbVIEW, however, when after you install LabVIEW first, then the Vision Acquisition, you can use the example Finder locate IMAQ or IMAQdx for LabVIEW examples: in LabVIEW, select help > find examples. This will open the Finder of the example. On the "Search" page, type the keyword "IMAQ" or "IMAQdx" (depending on your device) and look at the examples that come with the Acquisition of the Vision for LabVIEW.

• suggestion for soil moisture sensors that compatible with NI Labview?

  any suggestion for soil moisture sensors that compatible with NI Labview? Help me ~ ~!

  Fauzan says:

  any suggestion for soil moisture sensors that compatible with NI Labview? Help me ~ ~!

  Let me address your concerns about "compatible with NI LabVIEW" by asking you a question. Which soil moisture sensors are compatible with C++? Visual Basic? Visual C? JAVA?

  The sensors have a layer connection between himself and the computer. Sometimes, the sensor itself is directly connected to the computer via USB. Most of the time, there is a layer of connection which will interface to the computer - USB, RS-232, GPIB, PCI - and linking the layer is an acquisition of data, or simplified for your application, an analog input Module. It is up to you to set your software to interface with these devices.

  Now, I don't want to insult your intelligence. I bet you already know such things. But your question reads as if you have the same false ideas about LabVIEW with many people. That, LabVIEW is somehow a direct interface with the hardware, and you just bought sensors and LabVIEW magically presents the data. No matter what some people well planned would have you believe, this is not the case.

  OK, so take for example this soil moisture probe. It displays 0 to 3 volts and costs $30. So now we need a way to measure the voltage and send blood pressure data to a computer. We use USB. This thing right here will do the job and then some, for only $50, and is compatible with LabVIEW. My point is - LabVIEW is compatible with the device that ultimately connects to the computer - the sensor is simply a device of voltage output.

  I am not affiliated with or endorse I receommend or two devices, I've linked to, they were simply the result of a 10 second google search.
