Problems activating signal express 2.0 in labview

Hello,
I have purchased a copy of LabVIEW Base Edition 8.2.1 and Signal Express 2.0. I receive the following error when I create a LabVIEW VI containing a Signal Express VI (in this case a Signal Express Create Signal VI):
NI_MAPro.lvib:
This library is invalidly licensed for this computer. Please contact your National Instruments sales representative to request an upgrade to access the functionality of this library.
NI_Gmath.lvib:
This library is invalidly licensed for this computer. Please contact your National Instruments sales representative to request an upgrade to access the functionality of this library.
NI_AALPro.lvib:
This library is invalidly licensed for this computer. Please contact your National Instruments sales representative to request an upgrade to access the functionality of this library.
I have activated both the LabVIEW application and the Signal Express application and they both work fine indepedently.

Some SignalExpress 2.0 Express VIs require functionality that is only available in LabVIEW Full or Pro. Therefore, if you have LabVIEW Base and drop the Create Signal Express VI, your VI will be broken. (If you convert the Create Signal Express VI to a subVI, you could find the VIs in question).

I am trying to use generate code in signal express to import into labview.

I get this error when i try to generate code in signal express to export to labview . I have tries the error suggestions but I am still having problems. any help would be appreciated
The version of LabVIEW you are generating code into does not contain all the necessary SignalExpress support files. Make sure you launch the version of LabVIEW with SignalExpress support installed before generating code from SignalExpress. If you want to generate code into more than one version of LabVIEW, uninstall SignalExpress and all versions of LabVIEW except the earliest. Install SignalExpress, then install any other versions of LabVIEW. Copy the files from the vi.lib\express\SignalExpress directory of the earliest installed version of LabVIEW into the same sub-directory location of any other version of LabVIEW in which you want to include support for code generation.

Typically, this problem is repaired by following the directions on the error message. Since it was not, can you please give us more information so we can start determining the cause?
What version or versions of LabVIEW do you have installed? What version or versions of SignalExpress do you have installed? Could you post a file with a listing of the files in <vi.lib>\express\SignalExpress for the version of LabVIEW you are trying to use. You can either post a screenshot (in PNG or GIF format) of the directory dialog or use the command prompt to generate a list to a file (preferred). To generate a list with the command prompt, do the following:
Launch the command prompt from the start menu — Start»Programs»Accessories»Command Prompt
Navigate to the drive you have LabVIEW installed on ( usually C: ) — C:
Change directory to the appropriate LabVIEW directory — cd "\Program Files\National Instruments\LabVIEW 8.2\vi.lib\express\SignalExpress". Change the LabVIEW version to the one you actually are using. Do a directory listing and redirect the output to a file — dir > filename.txt. You can use any full path for the filename.txt. If you specify a simple name, it will end up in the current directory.
Please post your project. Verify that you are using the version of LabVIEW you think you are by launching it before you start code generation.
Thanks for your patience.

Export to Excel problem in Signal Express 2012

Equipment used: PXIE-8102 CELERON T3100 1.9GHZ Controller Windows 7, PXIE-1071 4 Slot Chassis, PXIE-4140 4-Channel SMU 1.7.5 version.
I am using Signal Express 2012 and the SMU to plot the I/V characteristics of FET and other active devices. I am able to obtain the anticipated curve traced results but I am not able to Export the data to Excel directly from the Data View using the Microsoft Excel option. The error message is: Data could not be sent to Microsoft Excel. Please ensure you have a properly licensed version of Microsoft Excel. See attachment.
We have checked our version of Microsoft Office, it is Professional Plus and has the correct volume license so it does not revert to a home or student version.
I have been able to use the Export to Excel function directly from the Dataview when I was using one of the waveform tutorials supplied with Signal Express so I suspect it is a function of the SMU.
In conversations with an NI support engineer he felt it may be a problem with "an active x call is just not seeing the license for some reason", his suggestion is to drag the data into Excel rather than use the Data view tab. Because the SMU is being used in a production environment it is not really appropriate to have the operator work at this level so I would rather figure a way to have the data exported using the Data View tab.
Anyway please can you let me know if there are any known work around for this issue.
Thank you

Where can i find labview signal express DAQ assistant at?

Hi, i need help
Q1) where can i locate Labview signal express DAQ assistant at?
Q2) Is Labview signal express functions same as Labview 8.6 ?

LabVIEW Signal Express and LabVIEW are two different products.
If you are talking about the DAQ Assistant, then you need to have the latest DAQmx driver installed and you should be able to find in the Measurement I/O palette on the LabVIEW Block Diagram.

Signal Express Large TDMS File Recording Error

Hello,
I have the following application and I am looking for some tips on the best way to approach the problem with Signal Express:
I am attempting to using Signal Express 2009 (Sound and Vibration Assistant) to collect random vibration data on three channels over an extended period of time -- about 20 hours total. My sample rate is 2kHz. Sampling at that rate over that period of time invovles the creation of a very large TDMS file, which is intended for various types of analysis in signal express later or some other application later on. One of the analysis functions to be done is a PSD (Power Spectral Density) plot to determine the vibration levels distributed over a band of frequencies during the log.
My original solution was to collect a single large TDMS file. I did this with Signal Express recording options configured to save and restart "in current log" after 1 hour worth of data is collected. I configured it this way because if there is a crash/sudden loss of power during data collection, I wanted to ensure that only up to an hours worth of data would be lost. I tested this option and the integrity of the file after a crash by killing the SignalExpress process in the middle of recording the large TDMS file (after a few save log file conditions had been met). Unfortunately, when I restart signal express and try to load the log file data in playback mode an error indicating "TDMS Data Corrupt" (or similiar) is displayed. My TDMS file is large, so it obviously contains some data; however, Signal Express does not index its time and I can not view the data within the file. The .tdms_index file is also present but the meta data.txt file is not generated. Is there any way to insure that I will have at least partially valid data that can be processed from a single TDMS file in the event of a crash during mid-logging? I don't have too much experience dealing with random vibration data, so are there any tips for generating vibration level PSD curves for large files over such a long time length?
My solution to this problem thusfar has been to log the data to seperate .TDMS files, about an hour in length each. This should result in about 20 files in my final application. Since I want to take a PSD, which ends up being a statistical average over the whole time period. I plan on generating a curve for each of these files and averaging all 20 of them together to get the overall vibration PSD curve for the 20 hour time period.

JMat,
Based on the description of your application, I would recommend writing the data to a "new log" every hour (or more often). Based on some of my testing, if you use "current log" and S&V Assistant crashes, the entire TDMS file will be corrupted. This seems consistent with what you're seeing.
It would be good if you could clarify why you're hoping to use "current log" instead of "new log". I'll assume an answer so I can provide a few more details in this response. I assume it's because you want to be able to perform the PSD over the entire logged file (all 20 hours). And the easiest way to do that is if all 20 hours are recorded in a continuous file. If this is the case, then we can still help you accomplish the desired outcome, but also ensure that you don't lose data if the system crashes at some point during the monitoring.
If you use "new log" for your logging configuration, you'll end up having 20 TDMS files when the run is complete. If the system crashes, any files that are already done writing will not be corrupted (I tested this). All you need to do is concatenate the files to make a single one. If this would work for you, we can talk about various solutions we can provide to accomplish this task. Let me know.
Now there is one thing I want to bring to your attention about logging multiple files from SignalExpress, whether you use "current log' or "new log". The Windows OS is not deterministic. Meaning that it cannot guarantee how long it takes for an operation to complete. For your particular application, this basically means that between log files there will be some short gap in time that the data is not being saved to disk. Based on my testing, it looks like this time could be between 1-3 seconds. This time depends heavily on how many other applications Windows has running at the same time.
So when you concatenate the signals, you can choose to concatenate them "absolutely", meaning there will be a 1-3 second gap between the different waveforms recorded. Or you can concatenate them to assume there is no time gap between logs, resulting in a pseudo-continuous waveform (it looks continuous to you and the analysis routine).
If neither of these options are suitable, let me know.
Thanks, Jared

Power factor in signal express

I have my voltage and current waveforms into SE and am having trouble trying to measure the phase angle between them so that I may calculate PF for logging purposes. Is this possible with SE or do I need a higher powered platform (LabView)?
Thanks

Hello all,
I would like to clarify that LabVIEW VIs can be used in signal express, however they need to follow specific guidelines defined in the following knowledgebase articles:
VI Guidelines for User Defined Steps In SignalExpress
Using a LabVIEW VI with LabVIEW SignalExpress
The EPM VI's , linked in previous post, could be modified to conform to these guidelines, however to do so LabVIEW is required.
To use LabVIEW VI's in Signal express follow these steps:
1. Add Step --> RUN LabVIEW VI (choose proper version for VI).
2. Select VI or source distribution (.llb) Path and configure the proper settings for your application.
More detailed information on how to run a Labview VI in Signal Express can be found at the following link: Signal Express Help: Run a LabVIEW 8.6 VI

Signal Express not activated with Labview Full Development System Volume License

I'm using a volume license manager to generate license for disconnected machines. I just upgraded to Labview 2009. The license files work for labview but are not working for signal express. I have the Labview full development system which included signal express in the past. Both labview and signal express work fine on my computer that also has the volume licensing manager software installed. This computer is connected to the license server. I need to get signal express activated on my disconnected machines.

LabVIEW Full Development licenses still include Signal Express. Are you saying that whenever you are connected to the server you can run Signal Express just fine, but whenever you create a disconnected license Signal Express is not able to launch? Can you verify that you are, in fact, checking a license out from the server whenever you are connected to the network?
If you still have trouble I would recommend calling NI support so we could get more informatioin (such as your license file, contract ID, etc).

NI Labview Signal Express activation dont work

Actually, signal express was working properly. We tried to run the upgradation cd on 4 Jan, 2010 that was provided by NI in august 2009. It was taking unexpectedly longer time and we turminated running the setup before completion. When we start signal express a window appeares that ask for activation (see attachment). Even after activating properly, same window appears time and again. We are unable to start signal express, please do the needfull.

Hello,
Sounds like aborting that installation may have corrupted your software. I would try to repair Signal Express with the original disks that you had and see if that works ok before trying to install the upgrade again. You can repair NI software by going to Add/Remove programs, find National Instruments Software and click Change/Remove. This brings up a window where you can select Signal Express and click the repair button. It will probably ask you for the CDs that you installed from ( the original CDs). Let us know how this goes, if you have problems or questions we will try to help.

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

When NI Circuit Design Suite Education Edition is installed first in a computer and the LEGO Mindstorms software second, the LEGO Mindstorms software doesn't work, it reports the following:
Error: A required file is broken
Possible Solutions: Reinstall the LEGO Mindstorms NXT Driver (tried but doesn't work)
Error code: 1003
Ordinal not found
The ordinal 18 could not be located in the dynamic link library NIVISV32.dll
Error loading "fantom.dll"
The operating system can not run %1
On other computers the LEGO software starts running, it displays part of the initial screen and then a small window opens saying that the Mindstorms software has has an error and that it will close. The previous report doesn't show.
If LabView Signal Express is uninstalled and then the LEGO software reinstalled, the LEGO software works.
I've dowloaded and installed new and old versions of the NIVISV32.dll and this doesn't correct the problem. I went as far as version 4.20 of the dll because it is dated in 2007 and the dll file installed by the LEGO software when it works is also dated 2007, but if I install the dll without uninstalling LabView Signal Express, the LEGO software continues not working.
Please advice how to correct this problem without having to uninstall LabView Signal Express first. If the LEGO software is installed first, is LabView Signal Express going to use and not to replace the old 2007 version of the dll installed by the LEGO software? Is there any LEGO software update 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 fix the problem. The computers are using Windows 7 and problems happen on both the 32 and 64 bits versions of Windows 7.
Any ideas???
Solved!
Go to Solution.

I couldn't reproduce the error either, but in our x86 computers this problem appeared after several months; we used LEGO Mindstorms last time in Summer 2011 without any problems and just three weeks ago when we were checking the computer for our Summer 2012 classes if when we noticed the problem. I’m still going to try to reproduce the error in an x64 computer where the problem appeared immediately.
Anyway, I’m attaching a word file with images of captured screens where you can see the error reports generated by LEGO Mindstorms and a series of steps uninstalling and reinstalling these program plus LabVIEW, until LEGO Mindstorms finally works after having uninstalled all traces of LabVIEW.
Images can be expanded and zoomed in to a better view of the details and if I can reproduce the problem in an x64 computer I’ll let you know.
Please see if you can find out something based on the images I’m sending.
Thank you.

How can i generate AMI line codes in LabView signal express?

i wish to conduct a project that uses AMI line codes. but i have a hard time using signal express to generate it. can anyone help me with that?

Hello Barry,
That is really a problem, in LabVIEW, we can only convert vi to the previous version, I have version 7.1 and so I can only convert to version 7.0 and you cannot open this too.
But I think that it's very easy to do what I'm trying to explain you.
Go to the cluster group in the functions pallete. Place an unbundle by name function in the diagram and connect it to the data that's comming out of the FFT Power spectrum vi - the pink (or watever) wire.
Click in the white part of it (it should contain something like f0), choose magnitude.
This is now an array that you can connect to the peak detector function.
Take care about the threshold and width parameters of the peak detector.
Take a look at your signal and decide the amplitude and width of the peaks you want to detect. The threshold is the amplitude above what you consider as a peak, the width is a little bit more complicated - to begin, 3 or 4 should be a good number if you signal is not too noisy - bigger widths will somehow do a kind of a low pass filtering to your signal.
The position output of your peak detector is an array of locations where your peaks were found.
Keep in mind you are now working in frequency domain and that position means something in the frequency domain.
The array you placed as input of the peak detector is an array of points starting in f0 and separated by df (the other elements of the cluster).
So to calculate the real value of the peaks, you have to multiply them by df and add them f0.
Sorry by the big text and sorry if I went too much in detail,
Hope it helps,
Paulo

Labview signal express to excel

Hello,
I'm using Labview signalexpress to acquire a signal. My problem is that I acquire 20 seconds of my signal (and I see it on the graph), but the problem is that I can export to excel the only 1.35 seconds, whatever the number of samples. How could I export to excel the entire signal?
Thanks
Solved!
Go to Solution.

I don't have signal express but a quick search found this link. It states that there is a setable limit on the size fo data sent to the clipboard.
"When you export data to Microsoft Excel, LabVIEW SignalExpress copies data samples to a clipboard for export. Use theMaximum Clipboard Data Export Size option on the Data page of the Options dialog box to increase the number of data samples the clipboard can contain. Depending on the amount of memory on a machine, large log files might not export successfully."
You might be running into that limitation when you try this method. Even if you increase the limit you will still not be able to paste more than excel's max size as discussed already. You would have to paste it into a text file or some other program that can handdle that much data. I would not use this method however. Seems like it would be to easy to make mistakes that way.
A .lvm file is just a text file so you should not run into any limits there. This is what I would use.

What are the main differences between Signal Express and Labview?

National Instruments provides a matrix so one can quickly compare the
various versions of Labview but no comparison of Signal Express with
Labview. Hence how does Signal Express compare with Labview? What
are some of the things one can do with Labview one can't do with
Signal Express?

Howard,
You clearly don't know what you are talking about. There is no "graphical version" of LabVIEW, there is just LabVIEW. Click on the article "Is LabVIEW a general purpose programming language?" written by the Jeff K. for some easy reading from a few years ago. It is all still true (except that object oriented features and recursion have been added in recent versions).
One of the main points at this years NI-week was the discussion of how processor development is switching more and more to multicore designs to improve performance because a simple boost in clock frequency is becoming more difficult. Linear, text based code is not well suited to take advantage of multticore design, while the dataflow based LabVIEW programming language automatically scales well to multiple processor cores, without any need to rewrite older code. I would say that only LabVIEW is futureproof in this respect. LabVIEW programmers are not wimps that are simply too stupid to write text based code. LabVIEW is not a toy language for people that don't want to learn a "real" programming language.
LabVIEW is arguably the best programming language in terms of getting things done! I've never felt limited with LabVIEW and my programs often don't even have anything to do with data acquisition or instrument control. The difference between text based code vs. LabVIEW is like "DOS vs. Windows", "Radio vs. HD television". "Trilobyte vs. Homo sapiens" (sorry Putnam ). Text based code is monochrome, archaic and outdated and its linearity imposes unecessary constraints on the programmer that can only be (partially) overcome by wasting even more time throwing even more code at it.
Sure, a seasoned text based programmer will initially have problems adapting to LabVIEW, just because you would need to adapt to and embrace the power of dataflow and not try to make a literal translation of the text code to LabVIEW, retaining old habits. If you get stuck, come back and ask here in the forum.
You were looking for object oriented features and failed. All you need to do is a quick site search. All the information is out there. Just because you cannot find it in the first five sentences of the glossy brochure does not mean it does not exist. Maybe you want to read one of the application notes such as:
LabVIEW Object-Oriented Programming: The Decisions Behind the Design
In general, you should avoid judgement until you have all information. Your opinions seem quite biased and superficial and not really based on hard facts.
Initially you asked about the difference between signal express and LabVIEW.

No thanks, there has to be a better way to get an answer to my
question than get involved in a two month study project.
If you would answer the first question quoted above, we could certainly help you with the decision. Isn't that the main purpose of this thread?
You can also contact your local LabVIEW Field Engineer to go over your requirements and help you make a decision. They usually know their stuff!

Report generation toolkit and signal express user step : problem of closing reference in "Stop" event

Hi all,
I'm trying to make a package of Vis to easily make Excel reports with Signal Express. I'm working on LabVIEW 8.2.1.
I'm using the report generation toolkit, so I build a .llb from my project which contains all the hierarchy of my steps, but also the hierarchy of dynamic VIs called.
I have made some steps, like "Open Workbook", "Write Data", etc.
My steps run well, excepts one step : "Close Workbook".
If my "Close Workbook" step is firing on "Run" Signal Express event, I have no error, so my reference is properly closed.
But if my "Close Workbook" step is firing on "Stop" Signal Express event, I have an error "1", from "Generate Report Objectrepository.vi".
I feel that I'm trying to use a reference which has been killed in the "Stop" step...
I would like to know what exactly do Signal Express on "Stop" event and why my close function does'nt run well.
Thanks,
Callahan

Hi Callahan,
SignalExpress (SE for short) does the following on the Stop event:
1. Takes the list of parameters that SE found on your VI's connector pane, and sets the values that the user set from the "Run LabVIEW VI" configuration page, if any.
2. Then tells the VI that SE is running the Stop event by setting the Enum found on your VI's front panel. This in turn should produce some boolean values telling your VI to execute the Stop case.
3. The VI is then run, with those values and states.
4. SE checks to see if any errors where returned.
5. Since this is the Stop event, SE releases the reference to the VI which it possesses.
Questions for you would be, is the reference to your Workbook linked to a control on your connector pane, or held in a uninitialized Shift Register. If it's held in a Shift Register, SE would not be aware of it, and would not be able to affect that reference.
Hope that helps. Feel free to post your LLB if it doesn't.

Event Acquisition in LabView Signal Express

I have the USB-6009 data logger and LabView Express. I am trying to record certain events as they happen in the process. The signal I am recording is a 0 or 10 V DC signal and each time that signal goes to 10V DC I want to record that as a event. I am not worried about the actual voltage just the event. I am not sure what the best way would be to set this up in LabView signal express. Any advice on how to achieve this.

Hi CoryB,
In SignalExpress you can create events by in the Recording Options tab clicking Events. Then, in the Category list select Add. From here, you can change the options for the event. Here is a link to the help on the events page.
Also, Dennis is absolutely correct. You will get better assistance with your questions if you post in the correct board.
