Unable to read shared variable in signal express

Dear all,
I am trying to read a shared variable with data type 'Array of Double Waveform' and the signal express gives a network variable error stating
"The data type of specified shared variable xxxxxx is not supported".
could any one explain why is this not supported or suggest a work around.
Munir.

Hi Munir,
the datatype you want to use is not supported in Signal Express. So if you choose this datatype you always get this error massage. As a work around I can recomment you to take the Double Waveform datatype this is supported, create a shared variable for each array element (waveform) and read this variable in Signal Express. This should help you out.
If you got any questions feel free to ask me.

Can I save data in a snapshot from signal express 2013 LE?

Can I save data (in txt or excel format) from a snapshot from signal express 2013 LE? My data buffer is too larege to export to excel. When I try to take a snapshot, I do not see any data. Are snapshots supported in the LE mode? This is the free version that comes with the USB 6009 ADC.

Yes, the snapshot function is available for SignalExpress 2013 LE. Does the snapshot function as intended when you try other projects?

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

Accessing digital inputs from signal express (TEK MSO2024)

Hi,
i'm trying to access the digital inputs of an TEK MSO2024 from signal express, but no luck.
I'm using SignalExpress2011, tkpdo2 ivi driver.
Seems like this driver doesn't support digital input, anyone got a solution or another driver?
*edit
topic can be deleted
on another system DI works...
Regards
alex

Hello,
The best to way drive digital outputs while acquiring analog inputs is to create two steps in Signal Express. Each step will execute relatively at the same time but there is no way to correlate or synchronize DIO with AI on a 6008 because DIO on that device is software timed while AI is hardware timed. Below is the 'Getting Started with Signal Express' manual which can aid in creating an AI and DIO step. Also, if you need additional examples later, they are located in the Help->Open Examples.

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.

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).

Joint time frequency analysis in Signal Express?

Is it possible to do joint time frequency analysis in Signal Express? I didn't see it in the Analysis section, so I'm assuming it's a separate tool that has to be added, if even possible in Signal Express. Help?
Solved!
Go to Solution.

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

Can I use to Labview 6.1 with cFP-1804?

I have Labview 6.1, Can I use to it wiht with cFP-1804?

Hello,
Yes, you can use LabVIEW 6.1 with cFP 1804. According to: What Version of the FieldPoint Driver Added Support for the cFP-180x? Support for the cFP-180x was added in FieldPoint 4.1.2. You must have version 4.1.2 or newer in order to see the network module in MAX and use it in LabVIEW. In your case, it cannot be a newer version because the newer versions don't have support for LabVIEW 6.1. Check which version of the FieldPoint software is included in the CD that came with your cFP 1804. In case it is 4.1.2 then you are all set; in case it is 5.0 or a newer one you will have to download version you need. You can find drivers at ni.com --> Product Support --> Drivers and Updates. For Product Line select Distributed I/O FieldPoint. For Software select NI-FieldPoint. For version, you will see v4.1 and then it skips to v5.0. Try version 4.1.
If it doesn't work. You will have to contact an Application Engineer in order to get a service number and then we will provide version 4.1.2. Dial the free telephone number according to your country or region. You can find the number at ni.com. The number for Mexico is 01 800 010 0793.

Custom square wave duty cycle in signal express

Hey everyone,
I am using an USB X Series Multifunctional DAQ Model 6361, with labview signal express 11 on windows7 (version 9.3.5) and I am trying to figure out if i can change the duty cycle of a square wave. I need to have one period be at 75% duty cycle and another 25% or something along these lines.
thanks!
Adam

Hi Adam,
I believe another Applications Engineer has corresponded with you concerning this issue already. If you are looking to generate a truly custom square wave where the duty cycle changes from one period to the next then you will need LabVIEW as this functionality is not supported in SignalExpress.
Using the Analog Output along with the Create Analog Signals options will allow you to specify one fixed duty cycle for your square wave, but this will remain constant throughout the generation.

NI VISA and Signal Express - Error -1073807202

So I did a search on this very common error that I'm also having, see error1.jpg. So one of the responses was to try and make an installer which I'm trying to do, see error2.jpg. I hope that is the right thing to check to fix the error (nobody said in the previous posts that I read). Then it asks me to find Signal Express. So I get out my DVD of Labview 8.5.0 and point it to the location (J: drive), see error3.jpg. But then Labview tells me that it is an invalid location. I mean WTF? I'm getting really annoyed by now and do another search of the forums. I find a post that says to look in MAX to see where Signal Express is located. So I do that and then put that location into the installer builder dialog box. Guess what it tells me, see error 4.jpg. So now what do I do????
Solved!

Are you getting error 1 when running an application on a deployment computer?
Yes, the error happens when I install the application (using the installer I built) on both the inhouse deployment computer and the computer of a customer I sent the application to.
I checked the deployment computer and the RunTime Engine is installed, but I see no referance to VISA. Surely you're not suggesting that I ask my customer (and any other customer who requires the application) to go to ni.com/support to download the 28.5 MB file (if my memory is correct) for the VISA drivers just to talk to a com port. So I need to fix my installer.
So I have a couple of questions.
Has this distribution problem been fixed in LabView 8.6.1? I have a copy just never installed it as I saw no real need to upgrade since my system so far has been working.
Did I check the right box, NI-VISA Runtime, (for Signal Express) to get the installer to include the VISA drivers?
I would like to get the next version right as I'm sure my customer has a reduced opinion of me for sending him a program that doesn't work.

Signal express 1.1 evl cannot find my device

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.

How do I get channel names written into a logged ascii file in Signal Express

Hi there,
This maybe a rookie question but I am a relative rookie to this software, and I hope it has an easy fix!
Background:
Take a load of analogue inputs from a DAQ device into Signal Express, first thing that hits me is that unlike labVIEW you cannot right click in the channel configuration window and change the name from say... Dev2_ai0 to Air Pressure? I feel that if this was possible then I would overcome my problem? anyway I can't so onwards...
I goto the DAQmx Acquire window on the top left and can right click and rename the channel, which is great... however this does not translate to the logged data as I get the ai0 channel names across the top of the columns and not the names that I have put in.
Is there anyway of getting data like the attached snippet?
Many thanks for your help in advance.

Channel names.gif ‏4 KB

Hi Dan,
Thanks for the reply, that has certainly fixed my issue as I wasn't expanding the channel and selecting the channel that I had renamed.
One last thing though:
I now not only get the individual channel name but the prefix for the DAQmx Aquire, for instance I get the Input of Braketest and then the channels under the input data.
It looks a bit like this....
Braketest - Front Pres
Braketest - Rear Pres
Braketest - FR Temp
Braketest - FL Temp
etc etc...
Now all of the channel names at the top of the columns have this long name. Can this be rectified? can I remove the "Braketest" bit?
By the way I am saving it as an ASCII so that I can read it in excel.
Many thanks, Neil.

Using Signal Express VI for DAQmx, timing & file size issues

I am using a Signal Express VI with my DAQmx. Long story short, my DAQmx VI's don't work in LV 8.6 (possibly IT installation error). I have a few issues (I'm a beginner so be easy).
First, I'm confused on how to get the timing correct. I am trying to read a 100 samples (2 channels) average them and repeat this at 30Hz and record this data.
Second, everytime I open the Signal Express VI (in my block diagram) and change sampling for example, click OK, then save my VI before running my program. I noticed the file on disk increased in size by the megabytes! All I changed were the sampling settings.
I appreciate any input, thanks in advance!

To your first concern, it sounds like DAQmx was installed before LabVIEW. Just reinstall DAQmx and it will work fine in LabVIEW.
For you second concern. To get 100 Samples at 30 Hz, you will need to change your channel setup in signal express. You will need Continuous Aquisition, with 100 Samples to Read at 3000 Hz. Then you code should work as expected.
