Ray,
I have created my own PreUUT.
In this PreUUT I call the dll for the PopUp windows to enter serial numbers and to select specified UUTs etc...
Yes I have tried to single step through the sequence but then the Problem doesn't occure. (I run it than in the Teststand developer environment) The problem only occures when I use my modified Operator Interface on the second computer. (on my first computer it works without problems)
My suspicion is that my modified simple operator interface makes the problem
what can be the problem? what dlls does the simple operator interface use? Is it possible that on my second computer some standard teststand or Lab Windows CVI dlls are not up to date?

Clear report in report window of simple operator interface

Hello,
hello I want to clear the report-window of the simple operator interface at the beginning of each UUT test.
I want that there is nothing inside this window while testing a UUT. Only at the end of a test I want to show the actual report
How is this possible?
regards samuel

Report.Reset should replace the current report data with the data in the string you specify, which in your case should be blank.
Do you have a PreUUT Sequence in your Client Sequence File?
If not try adding the first step in the attached sequence below the Report.Reset step in your PreUUT sequence. You may need to add the second step as well (below both new steps). Not sure if the second step is required. The first step tells the teststand engine that the report has changed, the second tells it to refresh all windows.

Programatically Loading Several Sequences Using LV Simple Operator Interface

I am playing around with the supplied LV(2009) Simple Operator Interface for running TestStand (4.2) and hoping that someone can point me in the right direction.  I know this may be too generic for a concise solution, but hopefully I can get some suggestions on the best approach for this. Here is a short description of what I am trying to accomplish.
I am testing 2 unique UUTs on a single test fixture that is controlled by a PCI-7831R DAQ. Each UUT will have a unique serial number and report generated. Therefore, I am using 2 unique sequence files created using TestStand. Basically, I want to be able to read in a barcode on the test fixture and have the operator interface load the 2 unique sequence files based on information contained in the barcode. The operator will then hit a button to start the sequence file executions.  I want the first sequence file to run and test the first UUT. Once the first sequence file is finished, I want the second sequence file to load and run on the second UUT.
I can use the simple operator interface to load both sequence files. I then have to select the combo box to select which one I want to run. This works fine, however, I am trying to automate this so that the operator doesn't have to open the files and continually use the combo box to select sequence files.
Any ideas or suggestions would be greatly appreciated.

I have figured out a solution (for my initial application at least) of programmatically loading the sequence files. When the operator interface first starts, there is a prompt where the user will scan a barcode that is loaded on the front of the fixture. For all of our product lines, we will have a unique format for the fixture barcode. Included in this barcode is a product specific software ID number. I create a folder with the same software ID number and store the sequence files there. I then parse the barcode and open all *.seq files in that folder. I have this working correctly now.
Once the sequence files are opened, the user must scan each UUT ID barcode before installing them on the fixture. The intent is to have both UUTs installed on the fixture at the same time so they can be tested serially.  If, however, they do not scan one of the UUTs, it will not be tested. Basically this is due to the fact that they may want to run only a single board. Once all of the UUT barcode scanning has been completed, I have another button that will execute the sequence files using the 'Single Pass' execution entry point. I agree that the 'Single Pass' and 'Test UUTs' points should be hidden from the user. Once the execute test(s) button is pressed, it will check each UUT barcode to make sure that it is valid. If both UUT's have valid barcodes, it will run the first UUT and then the second using the 2 sequence files that were previously loaded, otherwise, it will run only one or the other. The UUT(s) will then be removed and the process starts over again from the UUT ID barcode scanning. They will not have to scan the fixture barcode again since the correct sequence files have already been loaded.
Currently I have the UUT/Sequence File associations hard-coded in the UI. I will need to put my thinking cap on so that as we increase the product lines (several are already in the pipeline) we can use the same UI without any modifications. Scalability is King!

Including Limits, Measurements in Simple Operator Interface UI

Dear Experts,
I am in the process of modifying OPerator Interface such at that it must also display Low Limit,High Limits,Measured Value, Units. I am sure that it is possible only through expressions. I want this Limit columns value to be updated during runtime i.e., it must display the same value as we use to enter using Edit limits for Numeric test, Measured value should be the value in Step.Result.Numeric or Step.Result.NumericArrya.
I could just manage to create a parameters in each Sequence & Subsequence Parameters.Limits.Low, Parameters.Limits.High,,Parameters.Limits.Unit & just hard code the values in these. But for Parameters.Measurements i could get values in runtime using RunState.Sequence.Parameters.Measurement. I know this is not more efficient way. This might work only for Action, Numeric Limit.
For reference i have attached Simple OI Top Level.vi(where i have made some modifications) all other supporting files you can find in TestExec.llb. I hope i have explained my problem. If anyone find any confusions in understanding please let me know.
If someone tried this before please share your knowldege. Expecting your greatest support.
regards,
Bharat

Simple OI - Top-Level VI.vi ‏177 KB

Hello Bharat,
Adam is out of town right now. It looks like the error you are getting is occurring because you do not have the TestStand 3.0 UI controls installed for LabVIEW. You can check this by making sure that you have a TestStand subpalette in both your Control Palette and Function Palette. If you do not, you can go to "Start >> Settings >> Control Panel >> Add/Remove Program". Find the entry "National Instruments Software" and click "change". Find "TestStand 3.0" in the list of NI software installed on your computer. Click on "modify". This will launch the installer. Follow the steps and make sure to enable support for LabVIEW 7.0 (there is a step with a tree of features that you choose to install).
I took the liberty of saving the latest VI that was posted to my computer. I opened it with LabVIEW 7.0. This was verified by going to the "About" LabVIEW Dialog box that displays the version. I was running on the TestStand 3.0 engine. Besides the fact that you can only have one engine active on a computer at a time, I added a message popup to my TestStand 3.0 Front End Callback so that it would display when an instance of the engine is created. I did save the VI again and am not attaching it to this post. It should certainly work with LabVIEW 7.0 and TestStand 3.0 if everything is installed correctly.
Thank you for contacting National Instruments. Take care and good luck!

LabVIEW Simple operator interface deployment

Hi All,
I try to deploy a TS 3.1 application with a LV 7.1 Simple OI. I successfully (no errors) built the OI executable and created an installer with default options. I also built the Deploy TestStand System and created an installer with default options, except I selected only User Interface->Simple->Labview (no development system). I installed them on the target machine without any problem. The problem appeared when I ran the OI; it reported "Error 97 occured at Unknown System Error in TestStand-Set TestStand Application Window.vi->Simple OI-Top-LevelVI.vi. Possible reasons: Labview: Null Refnum was passed in as input".
I beleive this happened because the "Application Manager", "SequenceFileView Manager" and "ExecutionView Ma
nager" ActiveX Controls, which were required by the OI, were not present on the target PC.
Obviously, TestStand Deploy did not distribute them.
Does anybody know how to distribute these ActiveX controls or have a successful experience of distributing the LabVIEW Interface?
Thanks.

PPascal,
We've seen this error before, and it usually fixed by a simple reinstall. You could also possibly just run a repair on the TestStand engine within add/remove programs and this should also fix the problem. Please try this and post back if this does not fix the problem for some reason. Thanks and have a good one.

Updating system time with simple operator interface

Hello,
I need to update system time on the simple OI but when I use "Get system time and date.vi". The indicator on the front panel doesn't get updated every second, there is delay of atleast 5 secs. I tried using parallel while Loop method as well but still the problem persist
Any ideas guys?
Regards
Prav
Solved!
Go to Solution.

See attached simple OI modified to display time and date. When I run It, the update on indicator is like this 16:21:04-->16:21:09 (delay of 5 secs).I tried in time out event as well but no sucesss.

Error Loading a VI of a sequence in operator interface (Error Code -18002)

I am deploying a teststand sequence using LabVIEW adapter. After deploying, while running this sequence in operator interface in the deployment computer, I get an error saying that a particular step could not be loaded. This step calls a DIO initialization VI which basically uses DIO Port Config.vi from Traditional DAQ 7.4.4 version. Please see the attached image.
Software Versions Used: Teststand 4.0.1f1, LabVIEW 8.5, Traditional DAQ 7.4.4, Simple OI shipped with Teststand, windows XP
From couple of links from www.ni.com, I did following actions in my development computer:
1. Compile All the VI in LV 8.5 using Mass Compile including Traditional DAQ LLBs, simple operator interface etc.
2. Check if any VI or step is not broken.
After getting the error, I tried opening the same sequence in sequence editor in deployment computer (I am also including sequence editor with the deployment utility), I checked DIO Initialization step. I see the warning in step indicating that the VI is either broken or one of its sub is not located. I tried using Reload VI Prototype, it asks for LVDAQ.dll which is also bundled in my deployment files. After specifying this dll, I can run this sequence without errors but after I exit from sequence editor, it does not save the changes and I get the same error in Operator interface as well in sequence editor after re launching. Also I dont want to reload VI prototype as I dont expect some to do this change after deploying the testsequence.
Kindly help.
Thanks in advance.

Auto_Cal_18002 Error11.JPG ‏25 KB

I found solution for this. While creating the workspace for my sequence and other files, I used to include all the files including the LabVIEW VIs. Doing this, DIO Config VI seemed getting confused while searching for LVDAQ.DLL in the deployment computer.
I tried only including the test sequence and letting the teststand deployment utility select the VIs from the specified directory resolved this issue. I observed that in this case, all the sub vi and the support dlls gets placed in the support and data folder respectively. This resolved the issue.

Sequence file path programmed in operator interface

Hello,
I do not want to load the sequence file with the button OPEN_FILE etc.. for example how it is done in th Simple Operator Interface. I want to programm the path and the sequence file name in the Operator Interface. How can I do this that the correct file will be loaded
regards
samuel

I try to explain what you have to do without an example, because it is realy simple, and so we have no version dependency ;-)
I used the "simple operator interface" installed with TestStand (..\National Instruments\TestStand 3.x\Operator\Interfaces\NI\Simple\LabVIEW\TestExec.llb\Simple OI - Top-Level.vi). I added the method mentioned above in front of the Event-Structure (See attached picture) and added a path-constant, to define which Sequence should be loaded automatically.
Try this out. It works fine on my machine (LabVIEW 8.2.1, TestStand 3.5, but should be independent of Versions as long as you have TestStand 3 and LabVIEW 7 at least).
Hope this helps!

How can I view TestStands Operator Interface front panel, from a VI, while a test is taking place.

I need to view the sequences and steps that are displayed during a test session while running TestStand. Except I would like to view this in a LabVIEW front panel

JD,
I'm not sure if you're asking to be able to view the actual code module's front panel (ie. VI front panel) while it's executing, or if you just want to see the steps and overall sequence in a VI front panel. If the latter is true then you can use the simple LabVIEW operator interface that ships with TestStand, as Dennis mentioned in his answer. This would indeed be a great place to start if you want to add any further functionality to the operator interface. If the former is true and you want to see the actual VI front panels of the steps as they execute, you can check that box "Show VI Front Panel" from the "Specify Module" window in TestStand.

Error while executing interface

Hello Friends
The team is trying to integrate 3 sap standard tables into 1 table.
The have a requirement to interface @ 25 sap standard tables.
with 2 tables joining it works fine.
The 2 interfaces run a ABAP program in the form of background job; in the SAP system which integrates these tables.
While executing the program in the SAP system we get the memory dump as mentioned below;
Runtime Errors         TSV_TNEW_BLOCKS_NO_ROLL_MEMORY
Date and Time          24.03.2009 10:27:20
Short text
     No roll storage space of length 1994768 available for internal storage.
What happened?
     Each transaction requires some main memory space to process
     application data. If the operating system cannot provide any more
     space, the transaction is terminated.
What can you do?
     Try to find out (e.g. by targetted data selection) whether the
     transaction will run with less main memory.
     If there is a temporary bottleneck, execute the transaction again.
     If the error persists, ask your system administrator to check the
     following profile parameters:
     o ztta/roll_area            (1.000.000 - 15.000.000)
            Classic roll area per user and internal mode
            usual amount of roll area per user and internal mode
     o ztta/roll_extension       (10.000.000 - 500.000.000)
        Amount of memory per user in extended memory (EM)
o abap/heap_area_total      (100.000.000 - 1.500.000.000)
        Amount of memory (malloc) for all users of an application
        server. If several background processes are running on
        one server, temporary bottlenecks may occur.
        Of course, the amount of memory (in bytes) must also be
        available on the machine (main memory or file system swap).
        Caution:
        The operating system must be set up so that there is also
        enough memory for each process. Usually, the maximum address
        space is too small.
        Ask your hardware manufacturer or your competence center
        about this.
        In this case, consult your hardware vendor
abap/heap_area_dia:        (10.000.000 - 1.000.000.000)
        Restriction of memory allocated to the heap with malloc
        for each dialog process.
Parameters for background processes:
abap/heap_area_nondia:        (10.000.000 - 1.000.000.000)
        Restriction of memory allocated to the heap with malloc
        for each background process.
Other memory-relevant parameters are:
em/initial_size_MB:         (35-1200)
        Extended memory area from which all users of an
        application server can satisfy their memory requirement.
Note which actions and input led to the error.
For further help in handling the problem, contact your SAP administrator
.    You can use the ABAP dump analysis transaction ST22 to view and manage
    termination messages, in particular for long term reference.
Error analysis
    The internal table "\FUNCTION=ZODI_18011_18011\DATA=IT_FINAL[]" could not
     enlarged further.
    Memory location: "Session memory"
    You attempted to extend the data structure for the management of the
    memory blocks for table "\FUNCTION=ZODI_18011_18011\DATA=IT_FINAL[]". Howe
     the 1994768 bytes required for
    this were no longer available in the specified memory area.
    The amount of memory requested is no longer available.
How to correct the error
    Try to decide by analysis whether this request is
    reasonable or whether there is a program error. You should pay
    particular attention to the internal table entries listed below.
    The amount of storage space (in bytes) filled at termination time was:
Roll area...................... 16192
Extended memory (EM)........... 4189840
Assigned memory (HEAP)......... 0
Short area..................... " "
Paging area.................... 0
Maximum address space.......... " "
System details;
ECC 6.0 SP level 13 Oracle data base release 10.2.0.2.0.

I have checked with the sap notes but not sure enough with what tuning can be done for the same.
Basis memory checks are performed.
Thanks and Regards
Pooja

Hi Pooja
your problem is memory consumption problem,
if you want overcume these problem you need to tuning paramateors.
in SAP we have 3 types of memory areas are available
1. Primary memory that is called roll_area
2. Extended memory
3. Heap Memory
above each memory areas has reserved some amount of space
if not enoghf Primary memory for perticular transaction, then it will use extended memory then again not enoghf extended memory then it will go to heap memory, then that time transaction is terminated.
so you need to increase below prametor value in RZ10
ztta/roll_extension
next you need to restart sap other wise it wont effect which your changes values.

Deploying simple SharePoint 2013 feature causing error: "Error occurred in deployment step 'Add Solution': An unknown exception occurred while executing a sandboxed code solution request in the worker process."

When trying to deploy a sandboxed solution containing only a feature with a simple associated event receiver from VS 2013, I'm getting the following error:
Error occurred in deployment step 'Add Solution': An unknown exception occurred while executing a sandboxed code solution request in the worker process.\r\n|0
I'm working in Visual Studio 2013, deploying to SharePoint 2013.
The SharePoint project is very basic. I've only added a feature and an associated event receiver. It works without the event receiver. Then after I simply add the event receiver I get the error.
I've tried deploying directly from VS 2013 as well as publishing to a .WSP and uploading via web interface. Same error reported using both methods. I'm doing this using an Administrator account that I've confirmed is a site collection administrator.
Additionally, I've found that if I change Sandboxed Solution to False, deploy it, retract it, then change Sandboxed Solution back to True, then I can successfully deploy it. But this doesn't seem to be a permanent solution as the error will resurface a day
or two later...

Error while executing web part: System.StackOverflowException: Operation caused a stack overflow

Hello All,
I have a list with about 70 or so columns. When I try to access a NewForm for this list, I get an 'Unable to display this web part' error.
Looking at the Correlation always says it is a:
"Error while executing web part: System.StackOverflowException: Operation caused a stack overflow."
I have read many pages on the internet that it is due to an XsltTransformTimeOut value set to 1. I have applied the Feb 2012 CU and tried changing the value to 5, 10, 150, 250 and each time I reset IIS before I tried loading the form again. Each one has
failed and the correlation says the same thing (stack overflow).
I do not know what to do next because every page on the net says it is from that timeout value but I have followed the steps properly to change it but nothing has worked.
Thank you for your help!

You may be exceeding the number of columns threshold with 70 or so columns in your list.
Take a look at the Column limits here:
http://technet.microsoft.com/en-us/library/cc262787.aspx#Column
Okay, so please help me to understand this. It says the maximum value for single line of text is 276 and the size per column is 28 bytes. How would I know if I have pushed the limit? I just multiplied 28 x the number of single line of text columns in that
list and the answer is 840. I do have many other columns, such as multiple lines of text and choice. I do not know if the theory above is correct though, because 28 does not go evenly into 276 (276/28 = 9.857)
Please help me understand how to calculate my fields to see if I have went beyond the limits.
Thank you!
