• LEGO Mindstorms 2.0 crashes at startup when LabView Signal Express is installed first

  When NI Circuit Design Suite education edition is first installed in a computer and the LEGO Mindstorms software second, the LEGO Mindstorms software does not work, he reported the following:

  Error: A required file is broken

  Possible solutions: reinstall the driver of LEGO Mindstorms NXT (tried but does not work)

  Error code: 1003

  Ordinal not found

  The 18 ordinal not found in the library of dynamic links NIVISV32.dll

  Error loading "fantom.dll".

  The operating system cannot run %1

  On other computers the LEGO software starts, it displays the part of the initial screen and then a small window will open saying that the Mindstorms software has made an error and that it will close. The previous report does not display.

  If LabView Signal Express is uninstalled and reinstalled the software, LEGO, the LEGO software works.

  I downloaded and installed the new and old of the NIVISV32.dll versions and is not correct the problem. I went as far as version 4.20 of the dll because it is dated in 2007 and dll files installed by the LEGO software when it works is also dated 2007, but if I install the dll without uninstalling LabView Signal Express, the continuous LEGO software does not.

  Please advice how to fix this without having to uninstall first LabView Signal Express. If the LEGO software is installed first, LabView Signal Express will use and no not to replace the old version of the dll 2007 installed by the LEGO software? Y at - it an update of the LEGO software that corrects this problem?

  I repeat: I know a solution is to uninstall LabView Signal Express, install LEGO Mindstorms and then reinstall LabView Signal Express but I have 60 computers already cloned and deployed with this problem, so I don't want to go to this long process to solve the problem. Computers use Windows 7 and the problems occur on both 32 and 64-bit versions of Windows 7.

  Any ideas?

• NI USB-6251 - Signal Express - Input Ports display signals idential

  Hello

  I plugged a DET50B (phototedector) at the port of entry Ai0 in my case NI USB-6251 and thanks to LabView SingalExpress 3.0.0 took a look at the Ai0 signals and Ai1 by clicking on the following points:

  Acquisition of Signal-> DAQmx acquire-> analog input-> voltage

  I was expecting the Ai1 signal or 0 Volt, because there is nothing connected to it and the Ai0 signal vary in what concerns the light I was shinning on the photodetector. Instead, the Ai0 amplitudes both Ai1 were identical and corresponded to the light I'm shinning.

  How is it that these ports appear to be connected? It's the same thing when I opened other ports for viewing by SignalExpress except the Ai8; This one seemed to be at zero (probably because he does not physically exist on the NI USB 6251 which Ai0 - Ai7).

  No, you will not read 0 Volts to a channel not connected. Do a search for 'ghosts' for a detailed explanation. If you want 0 voltas on a channel, you need to gnd.

  p.s. You do not have a signal generator Board. New questions should be mailed to multifunction DAQ and Signal Express cards

• How do I capture the output of voltage full bridge with Signal Express NI9219

  Hello.  I'm trying to do and calibrate a load cell with the installation of full-bridge strain gage.  I use a NI9219 module with a cDAQ chassis.  Is it possible to capture the actual output voltage?  Signal Express gives me a value of strain, but I really need to know the output voltage.  Where to look.  I need only two channels for full-bridge.  I think that could connect the wires to the two remaining channels and read the output voltage of the strain gauges which would be connected as a tension of the 9219 entry, but I think that Signal Express could give me the voltage and output voltage directly.  Any input would be appreciated. Thank you!  P.S. I only use this equipment on occasion and am not the more familiar with it, so keep things simple for me.  Thanks again.

  Hi jgh@AET,

  The NI 9219 measures the ratio of voltage full bridge in hardware sensors, allowing any variation of the voltage to cancel. You won't be able to measure the output voltage of the sensor regardless of the voltage without additional channels, but you can measure the ratio of raw tension using the type of Bridge (V/V) . You can also use the type of measure of Force (bridge) measurement of load cell with engineering units (N, lb, kgf, no strain).

  This screenshot shows where the two Bridge (V/V) and Force (bridge) can be selected in the DAQ Assistant:

  

  These types of measurement were added sometimes around DAQmx 9.1, so if you have an older version of NOR-DAQmx, your DAQ Assistant maybe not them. The latest version is currently 9.4 of NOR-DAQmx. Front of NOR-DAQmx 9.1, the approach to recommend to measure the load cells was to use the custom with Excitation voltage type and a custom scale. However, Tension Custom excitedly can't Bridge of calibration in the DAQ Assistant.

• Double counters in Signal Express with a USB-6229

  I have a USB-6229, which I'm running via SignalExpress, and I am trying to simultaneously record two inputs of meter.  However, it seems that he has trouble to add the second channel.  When I add the first string via signals acquire > DAQmx Acquire > counter entry > Position > angular and select ctr0 channel, he (correctly) lists PFI8 and PFI10 as inputs of channels A and B.  However, when I add the ctr1 channel to the same task (via the blue and the button "Add a channel"), he still lists the same PFI8 and PFI10 as input.

  On the other hand, if I first add ctr1 then add ctr0 Secondly, it lists PFI3 and PFI11 as A and channel B for the two entries of meter.

  How can I get the two counters operating independently?

  Thank you

  Josh

  He realized that I can't run two meters of a single task in Signal Express (unlike, say, two analog inputs).  Once I added it as two separate tasks, everything works fine.

  Now I have problems of synchronization.  Looking through these tips and documentation, it seems that I will not be able to fix this via SignalExpress, so I continue in LabView.  I'm having some problems with it, but I'll post in a new thread here.

• Signal Express version unknown problem with Labview VI

  Hi all

  I am trying to run 2010 Labview Signal Express VI. It gives me "unknown version" problem. When I checked for Labview versions, he said 10.0f2 and Signal Express can read the version of LabView 2010. I don't understand this. 10.0f2 is not just a patch for version 10.0? I will appreciate if someone can help me with this.

  Kind regards

  Kanu

  Hi Kanu,

  I tried to write a simple VI and its importation to the Express Signal and I have not had any problems. I use 32-bit LV2010f2 and Signal Express 2010. I have attached the VI I used so that you can try it yourself. I followed the instructions of this KB to create a distribution of the source file. If you follow this KB and still can't make it work, can you please post the VI?

  Thank you

• Turning off IEPE signal Express with 9234?

  I have a module 9234 and I can't understand how to disable IEPE while using the Signal Express.  A new tab named "Device" appears when you watch 9234 modules, but which has only a drop-down list to select the AC/DC coupling.  MAX displays a checkbox for IEPE, but I can't find that in the Express of the Signal.

  Any suggestions?

  Thank you

  Hi ChrisCW,

  In order to set the IEPE, you must choose a task of nonvoltage such as acoustic pressure or acceleration.  You can see in the photo I have both source IEPE and value available.  If a task of tension is the only one that has meaning for your application, you can always use one of the other and adjust the data.

  I'll go ahead and submit a product idea to have this added to the task of blood also.

  

• Questions about the Installation of Signal Express Version 2.5.0

  Hello

  I have a silly question on installation of Singal Express Version 2.5.0. Previous student installed on the computer in my Department, but I can't find the installation CD of Signal Express 2.5.0. The only thing I found is Signal Express Verstion 1.1.1. Is there supposed to be any extra CD to update. I need to install Express of Signal on my laptop. Thank you very much.

  Ningyu

  Hello

  Please post on the Forums of NOR. Unfortunately, we are unable to upgrade to version 2.5.0 of the 1.1.1 cd. However, if you have your serial number, you can download the evaluation version of 2.5.0 section and activate it with your serial number and the computer. The download is located here http://joule.ni.com/nidu/cds/view/p/id/981/lang/en. I hope this helps!

• Analysis of frequency common time in Signal Express?

  Is it possible to do joint analysis frequency time Signal express?  I don't see in the section "analysis", so I guess that it is a separate tool that should be added, if possible still Signal Express.  Help?

  SignalExpress does not natively support joint time frequency analysis.  However, check out the Sound and Vibration toolkit that expands the SignalExpress.  It can do what you want.

• Can I have the user enter a variable that will be used to Signal Express?

  We seek to use the Signal Express to collect data of analog sensors and load cells. We would like the user to be able to enter a variable that the program Express of Signal can act on. Is it possible within Signal Express?

  Hello

  When you select 'Change destination', it will fill with all stage settings that are supported for the given control used.  Not all the steps or step settings are able to be adjusted when the operator mode.  That is why you were only able to bind controls to step DAQmx Acquire and filter (they are only available to bind in your configuration steps settings).  The forumla node is not able to reference an entry of order of the operator interface. You must manually configure the formula tab of configuration step for that particular step.

  I would recommend if you want that more customized the user interface and approach programming using an application development environment.  Signal Express is ideal for acquisition of signals and perform analysis and basic treatment, but if you want more functionality LabVIEW would be a better option.

• How to display the signal on a waveform graph in Labview Signal Express?

  Hello

  I want to display a signal in Signal Express 3.0 in a "waveform table", but don't know how to do it and I think that it may be impossible?

  In Labview, there are two ways to view data, a 'waveform table' or a 'waveform graph. The great thing with 'picture of waveform' is that it allows you to set a length of history and you can see the data move to the left (option graphic strip) that samples are recovered. It works perfectly.

  In Signal Express I can only select "Graph XY" or "Waveform curve" by doing a right-click of the mouse, but I can't select "table of waveform. Is it really true that it is not possible to view data in a graph of waveform "with Labview? (1 analog signal during streaming, 100 samples to read at the rate of 1 K)

  Thank you in advance,

  Enrique

  Hi Enrique.

  You are right that there is currently no graphic waveform in SignalExpress. The thing nearest you can join, is saved data under a log and then he looks one when recording (which I know this isn't quite the same interactive behavior).

  For your last comment, you wrote 'waveform curve', but I guess you meant 'picture' here as well.

  Sorry about that. We recently received this request, then perhaps in a future version.

• NI 6552 Signal Express sampling rate

  I'm generating multiple signals for Signal Express. When I run them, some work well and others not, in other words, for some changes in sampling rate signals! Thera are two options in Signal Express: 1. read file waveform 2 sampling rate. to manually set the sampling frequency. In both cases, the rate is changed when I run the waveform of my 90 MHz to 100 MHz.

  Any ideas?

  Hello

  The internal clock on the 6552 is generated from 200 MHz time base; Is that you can generate the frequency of 200 MHz/N where N is from 2 to a large number which takes up to 47 Hz. The driver for the Board of Directors will force the neerest value, so if you swipe from 90 Mhz to 100 MHz frequency, you will get 100 MHz in all cases. There is more information about the synchronization on the specs here:

  http://digital.NI.com/manuals.nsf/WebSearch/E4C93B141B71ED93862573CC005E8EA1

  Once, you run your project, Signal Express should show you the corced value, you can use this to read the actual frequency generated.

  I hope this helps.

• I can read two-channel USB-6008 using THE Signal Express?

  Hello world!!

  Is possible to read the two analog inputs at the same time?

  Example: Using Signal Express, I need to read the (channel 0) analog input and analog input (channel 1) at the same time.

  I try this but, the signal on purpose gives me an error message saying that I can't read several channels at the same time using the USB-6008.

  Is this true?

  Thank you

  André,

  Grato definition of pela.

• Signal Express 2009 causing NIMAX generate an Exception error message

  I have a system which gives an error message when I try to open an instrument in NIMAX. The popup error message shows 'unexpected error', with a code of "MAXKnownException. This system running Windows XP, and we Signal Express 3.0 with 4.3 NIMAX works perfectly. We went to Signal Express 2009 with NIMAX 4.6 and this problem occurs.

  Error log message which is gereated is

  "The niVISAui.mxx plug-in caused an exception in the CmxAggregateItemUI::GetToolbar function in the process of NIMax."

  Thank you

  Some info about failure for future reference, the problem is not benign in the pop up I chose to ignore the error message but any time, I tried to open an instrument in NIMAX I would get the same pop up and NIMAX was virtually unusable.

  The good news is that we were able to get this to work. The Signal Express 2009 package we received came with the associated device drivers CD. Unfortunately, NIMAX on the CD version was 4.5 and it turns out that Signal Express 2009 must have the 4.6 version to work. We took NIMAX version 4.6 out of the web site of NOR and cured the problem.
