Gleichlautende Kanallnamen im Diadem 10.1

Liebe Diadem Gemeinde,
ich habe eine Frage bzgl. gleichlautenden Kanalnamen im Diadem 10.1 In der Version 9 war es noch möglich, innerhalb von einer Kanalgruppe mehrere Kanäle mit gleichem Namen zu haben. Ich habe nun ein älteres Skript, in dem davon gebrauch gemacht wird.
Gibt es einen Trick mit dem ich auch mit Diadem 10.1 gleiche Namen innerhalb einer Kanalgruppe haben kann oder ist das prinzipell nicht möglich?
Besten Dank
Alexander

Hallo Alexander,
im Menü Einstellungen -> Optionen -> Allgemeines, Unterdialog Kanaleigenschaften kann dieses Option eingestellt werden.

i run into problems working with DIAdem 9.1 on Windows 2000 SP4!
The Diadem installation went quite well.
My problem:
only "Administrator" and "Power User" have the privilige to "WRITE" to the DIAdem install directory.
Trying to start Diadem as non priviliged USER I get something like:
DIAdem Configuration-Drive "C:\PROGRAM FILES\ NATIONAL INSTRUMENT\DIADEM 9.10" WRITE PROTECTED!
I installed & started DIAdem for one
time with Administrator rights. I activated the Product and exported
the KEY to a License Server. Everything works fine for Power Users an
Administrators. Only "simple" USERs are not able to start Diadem due to
missing WRITE permissions. i can't grand this permissions to
normal USERs :-(
Playing around in Registry -> "RegWriteAccessAllow" ("0","1") (DWORD) (HKEY_LOCAL_MACHINE/Software/National Instruments/Diadem/9.10),
didn't solved the problem.
I switched back to "local License" Managment (local Key files) but the Probelm persists.
thanks in advance

Hi DirkT,
Running DIAdem with User rights has different aspects we need to look at.
1) Registry Write Access
Launching DIAdem the first time with administrative rights registers some OLE components in the registry. After this step no more Admin rights are necessary for the registry. However running DIAdem as user might result in error messages as DIAdem tries to re-register the components again. You can avoid this by setting the RegWriteAccessAllow Key to 0 (see online help under "Administrator Notes")
2) File / Folder Write Access to the DIAdem Installation Folder
DIAdem needs write access to certain files e.g. the error logfile DEM_ERRS.001 or DESKTOP.DDD when saving configurations. You may change the folder where these file are being stored and searched for to a writeable folder by launching DIAdem with the "/d<NewFolder\MyDesktop.ddd>" start parameter or by setting the environment variable "DemDDD" to that folder. Then move the following files from the DIAdem installation folder to your new writeable folder:
*.ddd
userpar.par
dem_errs.*
3) File / Folder Write Access to other Folders
There are a number of other folders that DIAdem 9.x needs write access to and which cannot be changed. All of these folders are located by default under "%ProgramFiles%\National Instruments\Shared". Currently you need your Admin to give you write access to that folder and below
For future versions of DIAdem the team is working to make running under user rights easier.
Hope that helps,

Y axis auto scale not working in DIAdem 11

Hi
A few years ago I created a user dialog box for selecting and displaying channels in DIAdem view.
It worked fine for all DIAdem 10.X releases, but for DIAdem 11.X there is a problem with the y-axis scaling.
The channels are displayd as [n Systems (Linear)]
In DIAdem 10.X the y-axis for each separate graph would be scaled automatically accoring to the min. and max. values of the displayed channel.
In DIAdem 11.X the y-axis for each graph is scaled from 55.0397 to 133.7655.... for all channels, no matter what the values are for the displayed channel.
When I click the "Zoom Off" button the scaling becomes correct.
What do I need to put in to my script to make the y-axis scale correctly?
Below is the code that is used to set the scaling (no scaling for Y axis is set):
    R1 = SelectedStartTime 'this is a variable defined earlier in the code
    R2 = SelectedEndTime 'this is a variable defined earlier in the code
   View.ActiveSheet.Cursor.X1 = R1
   View.ActiveSheet.Cursor.X2 = R2
   View.ActiveSheet.Areas(1).DisplayObj.XScaling = "RangeZoom"
I've tried adding this code, to no effect:
    View.ActiveSheet.Areas(1).DisplayObj.YScaling = "n systems [phys.]"
   View.ActiveSheet.Areas(1).DisplayObj.YScalingMode = "automatic"
Solved!
Go to Solution.

I tried with Macro recording and Ctrl+A and the result was
Option Explicit 'Forces the explicit declaration of all the variables in a script.
R1 = 30
R2 = 52
Call View.NewLayout()
View.Sheets("Sheet 1").Areas("Area : 1").DisplayObjType = "CurveChart2D"
Dim oMyDisplayObj
Set oMyDisplayObj = View.Sheets("Sheet 1").Areas("Area : 1").DisplayObj
oMyDisplayObj.Curves.Add "[1]/Time", "[1]/Speed"
oMyDisplayObj.YScalingMode ="automatic"
oMyDisplayObj.Abscissa ="X-Cursor"
oMyDisplayObj.Ordinate ="Y-Cursor"
View.ActiveSheet.Cursor.X1 = R1
View.ActiveSheet.Cursor.X2 = R2
View.Sheets("Sheet 1").Areas("Area : 1").DisplayObj.XScalingMode = "RangeZoom"
WndShow "VIEW", ""
which seems to work fine. So there is only one difference to your code which is
.XScalingMode
instead of XScaling. Does changing this work with your code?

Improving graphics performance in DIAdem 11.0 Report?

Dear Forum,
when working on a Report layout, the poor graphic performance of DIAdem is a real problem for me.
For example, many diagrams with lots of data are on one page. One opens the proficiencies of one of the diagrams and changes e.g. the curves color or whatever and closes the dialog window. After this, the whole Report page is refreshed - wich takes up to one minute, depending on the amount of data displayed.
The strange thing is, when I close the given dialog window, and while the report page is being refreshed sent DIAdem to the taskbar and open any other application window, the process of refreshing the screen takes only 1 second instead of 30 seconds.
The question is: Is there a tweak to improve the speed how DIAdem refreshes the report page? Or is there any workaround other than switching applications during refreshing?
Thanks a lot.
Greetings from Germany
Oliver

Hello Oliver,
The easiest way to speed up the graphics performance in Report with large data files (or 3D graphs with lots of nodes) is to turn off the "Data Layer" (German: "Datenebene") in the "View" menu (German: "Ansicht").
That function basically turns off the display of all data in Report, but retains the axis systems, texts, etc., so you can still move them, place them and edit them without having to guess sizes. Once you're done with the report, simply turn the data layer back on and you're ready to create a PDF, print or save the result as an image file (JPG, BMB, etc.).
I think the performance difference you described (1 vs. 30 seconds) is due to the fact that once DIAdem has drawn a page, it retains an image in memory and will simply draw that image when you bring DIAdem to the foreground (or maximize it). After any edits you make to the report (e.g. change the color of a graph), DIAdem redraws the complete page from scratch, which takes much longer then just re-displaying an image that has already been drawn previously. Someone from the DIAdem R&D team could probably do a better job explaining this, but I think this is the explanation for the time difference in drawing.
Anyway, the "Data Layer" trick should hopefully solve your problem, let us know if that works for you.

DIAdem Report express VI works only with a single sheet template??

Hi,
I'm very new to Diadem and I'm using the 2011 evaluation version to try a report generation of LabView data (2013 version, evaluation also). I'm using the "DIAdem Report" express VI to generate a 2 pages, quite simple report; the first page has to contain some pictures and free text to be compiled with Labview strings, and the second page has to show an XY chart. The goal is to export in PDF file format.
Creating two separates TDR report models for each page and calling two instances of the DIAdem Report, the report is generated correctly with the expected value in two separate pdf files. If I'm using a report template with the two previous pages loaded in two sheets, the text value and the XY data are not loaded in the PDF file, causing a two pages empty export (only images, default text and chart border are visible).
I'm missing something? Attached a TDR file that reproduce the malfunction.
Many thanks in advance.
Solved!

1+2.TDR ‏59 KB

WorldTraveler
When I have a report that has multiple pages (Over 5) I like to use one tdr file for each of the pages, and then use the report append feature to make a resulting tdr and then a PDF.
(Search for report appending)
I make one cover tdr and one summary.tdr file, and then work to try to make the other sheets as reusable as possible. That way I can build each resulting large TDR from a appending of as many smaller tdr files as needed. This really cuts down on the maintenance time for reports, and results in large PDF at the end, so the users do not know the difference.

Error 7 occurred at _createExplicitChildObject.vi DIAdem report express

I am using DIAdem Report express in LabVIEW. I made a change in the file name and now it works most of the time but is generating an error. Sometimes it doesn't work.

This is the file path, it is constructed using string tools and then converted using string to path, then create folder then piped to the DIADEM report and Export Image function.
I get an error that cancels out the program the first time, then on subsequent runs it works just fine but still generates an error.
Error 7 occurred at _createExplicitChildObject.vi
Possible reason(s):
LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system. For example, use \ as path separators on Windows, : on Mac OS, and / on Linux. Verify that the path is correct using the command prompt or file explorer.

Difference between diadem and LabVIEW Report Generation Toolkit

I want to expand LabVIEW's reporting capabilities. Can someone tell me what the difference is between DIAdem and the LabVIEW Report Generation Toolkit for Microsoft Office.

Hello Mr Bean,
There are several major differences between the two solutions. I'll try and outline them as good as I can ...
The biggest different is that LabVIEW and its toolkits are programming tools and DIAdem is a ready to run application.
The LabVIEW Report Generation Toolkit basically provides an extensive library of VIs that allow you to connect LabVIEW to the MS Office library and create and edit reports in Word and Excel.
DIAdem is a stand alone application that was designed to post-process data from various sources. The tools included in DIAdem are:
1. NAVIGATOR: Allows you to import data from files (ASCII, binary, Excel, etc.) as well as DataBases (SQL/ODBC, Citadel, ASAM, etc.). The unique DataPlugin technology available within DIAdem allows you to import vitually and data file by creating a DataPlugin that describes the data format and gets linked to DIAdem. More information at: http://www.ni.com/diadem/dataplugins.htm
2. VIEW: Graphical and Numerical data inspection tool. Use cursors to zoom and scroll through your data, edit your data graphically and numerically and compare different tests.
3. ANALYSIS: DIAdem has a wide range of analysis functions, ranging from simple functions like integration and differentiation to FFTs, Order analysis and 3D data analysis.
4. REPORT: The DIAdem REPORT tool allows you to create reusable report layouts that can contain multiple axis systems (2D, 3D and polar plots) as well as tables (2D and 3D) and variables. The REPORT tool generates templates that can be usedwith multiple data sets due to the inclusion of automatic (or manula if required) scaling as well as extensive use of variables for annotations. Finished reports can be exported to printers, graphics files, the Windows Clipboard, HTML pages and PDF files (PDF writing is build into DIAdem, no extra software required). Using Scripts, it is also possible to create Word, Excel or Powerpoint reports from DIAdem automatically.
5. SCRIPT: The DIAdem scripting tools allows users to record macros or write scripts that automate complete sequences, for the import of data, via extensive analysis, to creating a publication ready report. Scripts can make reports "intelligent" by modifying the appearance of a report based on the data or calculation results that are going to be displayed in the report.
I recommend you check out the following link for more information: http://www.ni.com/diadem/
DIAdem is an extremly powerful tool for report generation. I am leaving to go on a business trip to Asia, but I would be more than happy to give you an Web presentation on DIAdem after I have returned. We could use your data and create a DIAdem report Script together online. My Email address is [email protected] and I will be back the week of Thanksgiving.

Questions on Saving and mining data with Labview and DIAdem

Hi,
I am sampling two signals at 200k sampling rate. I am trying to save the data on harddisk and analyzing the data using DIAdem.
If I save the data using mesurement file format .tdm and .lvm, the file size will be about 4 Gigabytes for only 10 mins' acquisition. It is very slow to process it.
I used the software Clampex and pCLAMP(Axon Instruments) before. At the same 200k sampling rate and also acquiring two signals, these programs save the data as .atf format and the size is only 400 MB for 10 mins' acquisition.
I wonder if there is also a good way to handle this situation using Labview and DIAdem, and how to do it?

Hi, Jonathan:
I tried the TDM binary file format. The file size is 800 MB per min acquisition and it will take a long time to just open these files. For my application, I have to take data for several hours. I am looking for a way to reduce the size of files.
Is there any other type of file format that can reduce the size significantly and can be handled easily?

How can I use the Diadem FFT Analysis GUI to give me multiple outputs given multiple inputs?

I have a few hundred channels I would like to perform FFT analysis on. They are mostly of different lengths, but I know I will have groups of 7 that will have the same number of data points. The default GUI will accept those 7 sets since they are the same size, but it will only give me one output as a combination of the sets. Is there a way to get Diadem to give me an FFT output for each set without having to select each data set individually?

The way it worked with the default channels, I had to make sure I wasn't going crazy because the way you demonstrated worked very well for me. That being said, for some reason what I am doing does not work. I've recently found that it is in changing the details in the GUI that makes my output different than yours. The differences are as follows:
1) I do not use a time channel. That is always left blank.
2) in the 'Window Functions' tab, I change the window type to Hanning
3) In the 'FFT Functions' tab, only amplitude is checked with the properties 'Peak amplitude', No Third/Octave, and Average amplitude is changed to arithmatic.
4) In the 'Time Intervals' tab 'Length/Start/Overlap' is checked, Interval length is changed to 1024, and overlap (%) is changed to 50.
I've also found that changing any number of these details from the default will cause my proplem to crop up. I am fairly sure that most of those options are just as feasibly done to one channel as they are to multiple. Is this a bug, or am I misunderstanding a property of FFT that has gone over my head? Please try changing a few of those properties since it seems like it should work just as well for all the channels as it does for just one, but that doesn't seem to be the case.
Another point of confusion is that while the window previewing the inputs in the GUI will show all the inputs I have selected, the window previewing outputs only appears to preview a single unknown output. That is just a side note though.

Is it possible to create a custom display type in DIAdem, for example a speedometer type instrument?

As an example I have velocity data which shows a vehicle accelerating from rest to 60 km/h and then travelling at a constant speed. As opposed to displaying this data using a 2D axis system is it possible to create a new speedometer display type to display this information? Maybe this display type already exists but I have not come across it yet? I've been using DIAdem for a few days now. The current version I am using is 11.2. It has been suggested in the past that it was possible to display data using numeric displays etc but I can't seem to find the features in v11.2. Thanks for your help in advance.

Hey Matthew,
I'm sorry for the [extremely] delayed reply - I have been out of the office (and out of the country) for two weeks with extremely limited email access. I've attached the files that I used to create the example you saw in the YouTube video embedded above. Please note that I threw this together pretty quickly for the video, and that it is not "commercial quality." Use this as a proof-of-concept upon which to elaborate to get started.
The parts are:
CAN Synchronization.tdv
This is the DIAdem VIEW Layout that contains the video, map, 2D axis, and embedded user dialog with ActiveX gauge control. Think of this as the "user interface" you see in the video.
Gauge.sud
This is the scriptable user dialog (SUD) box that is embedded in the VIEW Layout described above. It contains the ActiveX control which I have affectionately named "MyGauge."
DisplayCursorCommand.vbs
This is the short script that is designed to react to the event that fires when the cursor is playing in DIAdem VIEW. I have commented all 5-ish lines with their functionality.
In order to register the script so that it fires in reaction to the event when the cursor is playing, I chose to register it as a DIAdem UserCommand (Settings » Options » Extensions » User Commands) and then run the line of code:
View.Events.onCursorChange = "DisplayCursor"
You could do this elsewhere within some other script.
Let me know if you have any questions!

How does DIADEM import TDMS files? How gets every channel his number and groupindex? How can I determine which channel has which groupindex and number?

I store different channels in a TDMS file.
I like to have a time channel at the first position with group index 1 and number 1.
When I read the TDMS file with DIADEM the time channel (Float64) is on a differernt position, and the channels are not sorted alphabetically.
Here are my questions:
How does DIADEM import TDMS files?
How gets every channel his number and groupindex?
How can I determine which channel has which groupindex and number?

Joerg

Hi Jörg,
i suppose that you´re programme whose create the *.tdms file is writing on false position. Try to create datas with timechannel on first indes in diadem, then save it and then open it again. you see that all is correct. So please tell me what programm in what version do you use and please attache it here.
Did you use the library for creating *.tdms files like in the link ?
http://zone.ni.com/devzone/cda/tut/p/id/6471
Here you find the gtdms_8.x.zip - when you extract it and opened the *.llb you find vi´s for all functions e.g. writing 2d array of strings to *.tdms file
when you open the subvi´s then you see how created and writing datas/structure to *.tdms files. Because *.tdms is binary you can´t see structure with open it in editor.
When you don´t have Labview you can use the 30 days test of current version 8.5 under following link

How do I get the number of channels available in DIAdem using VBScript?

I want to know the last number of the available channels in DIAdem-DATA using VBScript. If there are not enough channels, I'll allocate new ones using ChnAlloc.
For the first run of the script, I do know there're 60 channels, but in a second run I might have created the additional channels already (if the script didn't fail) and I don't want to do the allocation a second time. So I need to know the number of the last channel. Unfortunatly I didn't find any function in the help providing this number.
Thanks,
Carsten

Hi Carsten,
I have a few thoughts for you plus some useful code. Bear in mind that you can change the number of static DIAdem channels (by default 60 of length 8192) as well as the number of available dynamic channels (by default 1000) to whatever you want. These memory matrix settings get stored in your Desktop.DDD file (DIAdem's ini file), so that each time you launch DIAdem it will create the channels according to your specifications. The maximum number of channels of all types that DIAdem can have is 65536 (2^16).
Secondly, don't forget that you can address channels by name or by number. If the channels are named distinctly, addressing channels by name is the most reliable method. If you use ChnAlloc() to allocate new channels, and you want to address those new channels by channel number, you MUST use CNo() immediately after creating the new channel in order to find out that channel's number. It will not always be the next available channel number, because the next available channel may not be long enough. ChnAlloc() will latch on to an existing channel if it can find one long enough, and it will create new channels only if it finds none of the existing channels suitable.
In the VBScript I attached to this email you will find all the DIAdem variables which contain information about the maximum available channels and the maximum length of each channel (not its currently set length). Note that DIAdem's data matrix is divided into 8 submatrices, each with 2 GBytes of addressable memory (2^31 Bytes). Each submatrix can have multiple static channels assigned to it. DIAdem's dynamic channels come first from DIAdem's application RAM (Windows allocates no more than 2 GBytes per application) then from the Windows swap file for its virtual memory
Now, in addition to the variables which tell you the maximum possible channel count and lengths, another very useful variable is "GlobUsedChn", which returns the highest channel number currently filled with some amount of data.
Ask if you have additional questions,

Hello Marse!
Sorry that I was not clear enough and add the hwo-to via OLE
For way 1. you have to add this lines to your Excel VBA code:
loadscript = IDIACommand.TextVarSet("T1","Value of T1")
For way 2. it is:
loadscript = IDIACommand.CmdExecuteSync("GlobalDim('MyGlobalVar'")
loadscript = IDIACommand.VariantVarSet("MyGlobalVar","Value of MyGlobalVar")
Inserted before your line
loadscript = IDIACommand.CmdExecuteSync("scriptstart('C:\BForce\LIBR\BForce2.VBS')")
Hope it is clear now! Otherwise feel free to ask

How do I change the numerical format of the axis in Diadem view and report

Is there a method for changing the format of the AXIS labels to show more significant digits? Second, I can't find how to display the menu shown in NI help document 3FIEI5LE. When I right click to (select properties) I get a different menu labeled (set proerties for display).
Thanks,
Doug

Hi Doug,
There is no way to configure the display of the X axis in VIEW-- this is for a quick look at or an interactive visual inspection of your data. For a fully configurable report creation environment you should switch to REPORT. Note that the last button on the top icon bar in VIEW with the tipstrip "Transfer to REPORT" will transfer what you currently have displayed in VIEW into a new REPORT layout.
In REPORT if you double-click on the numbers below the X axis, a "2D - Numeric display" configuration dialog will appear which has the field "Format:" in it. Type in "d.dddd" ("d,dddd" in Europe) or as many d's after the decimal character as you want to display. There are also other formatting options for scientific display, etc.
I honestly didn't understand your second question about the help dialog-- what version of DIAdem are you using?

How to create a shortcut menu in the VIEW panel of Diadem

Hi everyone,
Is it possible to create your own shortcut menu in the VIEW Panel of Diadem?

Hi Ovidius,
What do you mean by "shortcut" menu? You can add a custom menu to the top of any DIAdem panel and fill it with whatever menu items you want. You can also add/customize any icons at the top or the left of any DIAdem panel and program them to do what you want. There is additionally limited support in DIAdem 2010 and prior versions for adding custom context menus to VIEW areas. We are looking into expanding this support for DIAdem 2011.
