Hi all , 

I have basic knowledge of Teststand And I have given a task to create a Test Automation of ECU (Management ECU , Transmission ECU) . We have LabVIEW 2015 , Teststand 2015. When I search for Test automation using NI teststand , I found NI veristand is useful for real time test application. Referred link are 

  http://www.ni.com/white-paper/13062/en/ 

  https://forums.ni.com/t5/Past-NIWeek-Sessions/Automating-Embedded-Software-Test-Using-TestStand-VeriStand-and/ta- p/3519237

By referring these, I get confused in Veristand and Teststand as 

1. Veristand runs on Real time system where Teststand does not. But If I use Real time chassis with Teststand ,then whether system  would be same (except timing  parameter) or different? Because Veristand steps are  called from Teststand itself And It is possible to design the sequences in teststand using LabVIEW modules as adapter which run on Real time.

 

Where can I get more details for comparing Veristand and Teststand .

Please suggest.

Hello,

i installed Teststand 2016 32bit on a windows 7 64bit PXI computer.

There was no error during installation but after it finished there is no starticon on desktop.

In the directory C:\Program Files (x86)\National Instruments\TestStand 2016\ are a lot of dlls and stuff installed but no seqedit.exe.

There is also  folder NationalInstruments in Startmenu with "TestStand 2016 (32bit)" but it also only contains subfolders with

"TestStand 2016 (32-bit)\Documentation"

Tools

 

How can i solve this problem?

Or can i only execute TS64bit on a 64bit windows?

(During installation i selected to only install 32bit-version)

 

Thx

Hello, 

 

I made some StationGlobals for configuration last week and booted today but can't see most of variables.

Is it possible to clear the stationglobal variables? 

Not sure of this, I'd like to export stationglobals. Is it possible to export stationglobals?

 

When I doing more, problems are following more, unfortunatelly. :-(

Hi,

 

I am new to the test stand. I was given a task to add one more UUT serial number to an existing test solution. Basically the test solution is same. But the requirements tags needs to be changed in the report since they are different for new serial number.

 

For example,

 

I have tags Requirement_1 for UUT_SN1 and Requirement_2 for UUT_SN2 for the same test sequence. I need to pass the Requirement_1 or Requirement_2 based on UUT selection to the report while executing the test sequence.

 

Can anyone help in doing this?

Hi everybody,

 

I have a problem regarding the appearance (formatting) of a string variables in TestStand Repotrs (Reported Text or log).

And: the format is even different between Report Text and log. Perhaps there are even more possibilities to report Strings in reports. A figure of the original Labview string and the Teststand Report is attached. I added some dots to indent some lines; Main Problem: spaces and tabs are deleted in the report so I can not generate colums easily. Line endings appear with \r (but only in the report).

I would like to have a good formatting (diffent colums) in TestStand  AND in Labview, so using HTML formatting will not work in Labview...

 

Is there a possibility to keep the formatting even the TestStand Report is a HTML Document?!?!?

 

Thanks.

Hi,

My top level sequence is very simple. It calls five sequences which sit in five separate sequence files.

 

I the header of my report I'd like to have my five sub-sequence files version numbers. How to pull them out from the main sequence and push the information back to the process model?

Hi,

 

I have a parallel test with three threads that do not startsimultaneously, I need that execute a preset of the instruments only the first time.

I tried to create a Rendezvous on the first thread for execute a preset instruments and other threads if they are existing jump it.

Are there other alternatives or this might be fine?

I use a TestStand 2014.

 

Thank you

Hello,

i created some functions in C# that i want to use in TestStand.

One of them looks like this:
public void myfunction(int a, ref int b, StringBuilder c)
{
//somecode
}

 

When i insert this in teststand 2016 and run the step i get a Run-Time Error:
An error occurred while calling .NET member 'myfunction':
Object of type 'System.__ComObject' cannot be converted to type 'System.Text.StringBuilder'.

Errorcode: -17500; Operation Failed.

 

Question: Is it not possible to use type StringBuilder?

 

Thx

My sequence sorts through a different selected sequence for prototypes that haven't been updated,  it updates them and may enter a value for that parameter.  I'm trying to discover what the type is of that parameter dynamically, to display to the user.  For VI calls and for Sequence Calls the types are returned as a number.  What is the corresponding number?

Hi,

I am using the TestStand User Interface C++ Simple UI.

I would like to customize the UI, not showing the Fields "Description" and "Settings" during execution. 

Only "Step" and "Status" shall be shown.

I have browsed the C++ source code, but can't find the point where to enable/disable visualization of these fields.

Can anyone provide me with suggestions?

 

Thanks in advance,

Best regards,

Using this post I was able to customize the UUT information window(Parallel Process Model) from LabWindows CVI and build the modelsupport2.dll successfully.

 

Now when I try to execute a simple sequence file in TestStand under Parallel Process Model, it works fine.& I can see the following window,

 

 

Now my question is how do I access the property of the check box - Exit on First Failure(in red), at client sequence level.

any suggestions would be much appreciated.

I want to get the start date-time which is also logged in the TestStand report under "startDateTime" tag. And, I want this during the sequence execution.

Can anyone tell me which variable I should be looking for in the TS engine?

Hi Guys,

 

I was recently was given a machine to use with TestStand 13 and for some reason the editor window is always on top.

It just bugs me because I have to minimize it to use LabVIEW or any other windows. This might be a simple setting but i cant find it. Any suggestions will be great. 

 

Thank you,

Hello,

 

I can't seem to find the answer when doing a search on the forum; however, I would like to remote login and launch TestStand sequence. Right now, whenever I launch the sequence, TestStand would prompt the login screen.

 

I know that I can disable or remove the login, but how do I like login through a specific user through command prompt.

I tried using the AutoMgr option in dcomcnfg and it's still popping up. Is there an option that I'm missing?

 

Any help is much appreciated.

Hello

 

I want to create a UUT report file with the following format :

C:\\temp\\Reports\\ + Partnumber_Revision + \\Filetime\\FileDate\\Unique.xml

 

Therefore i have selected the "Specify report file path by expression" option and created the following path :

"C:\\temp\\Reports\\" + Locals.UUT.UUTPartNumber + "[$(FileTime)][$(FileDate)]$(Unique).$(FileExtension)"

But this doesn't work. Problem is the "locals.uut.uutpartnumber".

 

How can i get my partnumber and revision, stored in my UUT sequencefile as Fileglobals, in the reportname ?

Hi All,

 

I was going through the step execution flow related page in TestStand help and I believe the links are wrongly specified in this particular page. Here is the link to the step execution page: http://zone.ni.com/reference/en-XX/help/370052R-01/tsfundamentals/infotopics/step_execution/

 

For example, when the step is skipped (Action 3), it is mentioned that execution will move to Action 31, which is to execute the post action for the step. But post action will not be executed when a step is skipped. Also when I press on the link mentioning "Action Number 31", it actually points to "Action Number 33". Most of the links in the page take me two actions down the actual action number mentioned in the link.

 

Also, there is a paragraph below this table that also has few links and they are also pointing to a different Action number in the table and few action numbers are specified without any link. Someone please confirm this behavior so that the step execution is understood in the right way

 

Thanks,

Saranya

Hi,

We are generating data, in which we want to zip the data with a password that the user cannot access, during the test in an automated step.  I want to use a property to contain the password, but I don't want it displayable in raw text.  My thoughts then go to password protecting a property.  But this doesn't seem possible.  I do see the ability to hide properties however, which could be a solution. (Set a stationglobal with the password, hide it, and reference this property in the step that creates the archive).  Is there any other viable way anyone knows about to keep passwords away from end users when automating creation of a password protected file?

 

Thanks

Dave J.
