Install LabVIEW, LabWindow, TestStand and Device Driver

I need to install LabVIEW (on DVD with Device Driver), LabWindow, TestStand, and Device Driver.
What's the best order? TestStand, LabWindow, LabVIEW w/ Device Driver?
Do I need to reboot 3 times? or once after all installed?

The way I did it last (LV8.5.1, TS 4.0) was in this order. LabVIEW, LabWindows/CVI, Signal Express, Toolkits, Device Drivers, than finally TestStand. I know you want to do TestStand last. It worked great for me.

LabVIEW vs Teststand

Hello all,
I been using the LabVIEW for the past two users in Machine Vision Application Development. I have the following questions on my mind,
1. I would like to know what is test stand.
2. Where it can actually used.
3. Is vision development can be done using that.
4. What is advantage of this over LabVIEW..
Waiting for replies...
Thanks.

Hi,
TestStand is a test sequencer whose engine is accessible via a powerful API, thus you can execute and manage TestStand sequences (*.seq files) from many different programming languages and development environment.
Basically, you will create (or use) your own operator interface to execute or edit your sequences, these sequences are made of different steps that consist in calling external component like VI made in LabVIEW, DLL made with LabWindows/CVI or Visual Studio and even .NET Assemblies. All these external components may execute some routines that will affect hardware (for example checking if a DC motor will move according to the set point you set).
You can then check if the tests pass of fail and then automatically edit a report.
You cannot compare LabVIEW and TestStand, they are not made for the same purposes. You can see LabVIEW as an "add on" for TestStand in a way...

How to Pass Container in a queue from LabVIEW to TestStand?

I was succussful to pass simple type(string, number) using queue from LabVIEW to TestStand base on the example: Use TestStand Queue.seq.
I want to pass a container variable from LabVIEW to TestStand. But there are some errors happen.
Anyone who can help on this issue?
Thanks in advance.

You ought to have a listener somewhere that calls a function
to then set up the loaded swf. In that function you can do this
kind of thing:
var ldrmc:MovieClip;
function swfloaded (e:Event) {
ldrmc = null;
if (e.target.content is MovieClip) {
ldrmc = e.target.content as MovieClip;
If the swf was published for AS3, then ldrmc will end up
being a pointer to the root of the swf, and you can call functions
or set variables however you like. If it was an AS2 swf, ldrmc
would be null.
Inside the loaded swf you could try trace statements, to make
sure you're looking up the hierarchy far enough. Like this:
trace(MovieClip(parent.parent));
If that doesn't trace MainTimeLine, then maybe you're not
looking up far enough. Don't forget that the swf itself is in a
loader, and so may be one level down from where you thought it was.

How do I return a Boolean array from LabView to TestStand?

I am trying to return a Boolean array from Labview to TestStand and have TS evaluate the results. I can do this for arrays of integers or reals but booleans do not work. I tried copying the PassFailTest step type and adding an array of Bool but I couldn't get it to evaluate the array. It simply always passed. How can this be done?
Bob A.

I have thought about evaluating the Boolean data in TestStand but, as you say, this is a lot of work. What I have been doing is to map the boolean data to integers in LV (very easy) and then use the multiple numeric step type to evaluate the integer array automatically. This feels kludgy and I have tried a couple of times to create a "multiple boolean" step type with little success. I'm surprised TS hasn't anticipated a test returning multiple pass/fail results. I do this all the time for production code.
What I have tried is to copy MultipleNumericLimitsTest data type to a custom type and add a BooleanArray with a data type Array of Boolean[0..empty]. Then when I specify module, I select Step.BooleanArray as the value. The last step (that I know of) is to select Step.BooleanArray as the data source in the edit limits window. At this point if I run the test, I get the error "expect numeric, found boolean" (or something similar). When I look at the properties of my custom step type, the Substeps has DoMultiNumericMeasEvaluation as the Post-Step. I believe this is the root of my problem but I can't figure out how to change this to "DoMultiBooleanMeasEvaluation" or similar. Any Ideas?

How to send a path from labview to teststand.

Hi!
I have a DLL that I have developed in LabView and as a input parameter I have a path to a file
but if I in the LabViewCode uses String to recieve the path from TestStand and the path includes \T
these just disapperes.
ex:
I send "C:\test.vi" to LabView from Teststand
If I check the Path recieved in LabView i get "C: est.vi"
Instead if I in LabView uses Path to recieve data from TestStand I get an error in Teststand.
How should I do?
/Andreas

Labview strings use the backslash "\" as a special character. \t is a tab, \n is a newline, \r is carriage return, and so on. To send a real backslash use two of them, like \\. So your path string should be "C:\\test.vi".

Using ModelSupport2.dll in LabView without TestStand

I would like to use the ModelSupport2.dll purely in a LabVIEW environment as either by a "Call Library Function Node" or "Active X" or ".NET" without using TestStand.
In particular I would utilize the the "DisplayPassBanner" and "DisplayFailBanner" functions. I want the banner pop-up's so I can provide a consistency between applications that don't use TestStand and those that do.
The DLL call requires a numeric input "context" which I am not sure what it needs for a reference number.
In teststand it is passed an "Object", "CVI Active X Automation Handle", "By Value" from the "ThisContext"
How replicate this or create equivalent in LabVIEW
Any suggestions appreciated
A

A,
if you are looking into the sources of ModelSupport2.dll (the sources are included as LabWindows/CVI project and the needed C files), you will see that the display banner functions do access the object referenced by the parameter 'context'. The context is a reference to the dataset of a running TestStand execution when called from the TestStand process model.
So it will not be possible to use those functions if you are not going to use TestStand/running an actual sequence.
There are, however, two ways you can go for:
a) Design a LV VI dialog such way that it looks like one of the banner and call it as a subVI.
b) Use the LabWindows/CVI sources of ModelSupport2.dll to copy the banner dialogs into a new CVI project (from modelpanels.uir) and create similar functions into a custom written dll which do not require the ActiveX handle 'context' to be passed.....
hope this helps,

What is the best way to open close and pass instrument handles from labview in teststand parallel model?

I have a number of test systems that use a parallel model with labview. We have a good number of instruments(PXI).
What is the prefered method for open,closing and passing instrument handles in teststand using labview?
Solved!
Go to Solution.

Hi,
No, Below is a bit from the Session Manager Help
Currently, Session Manager supports the following instrument session types:
IVI Sessions—Use an IVI session to obtain the C-based instance handle for an IVI logical or virtual instrument name. NI Session Manager does not support IVI-COM drivers at this time. When IVI-COM drivers are available, you can use an IVI session to obtain an ActiveX interface reference to an IVI-COM driver.
VXIplug&play Sessions—Use a VXIplug&play session to obtain a C-based instance handle for a VXIplug&play logical or virtual instrument name. Configure VXIplug&play names in the <VXIplug&play directory>\<Platform directory>\NISessionMgr.ini file.
VISA Sessions—Use a VISA instrument session to obtain a C-based viSession handle to a VISA resource or logical name. Configure VISA logical names in the <VXIplug&play directory>\<Platform directory>\NISessionMgr.ini file.
Custom Sessions—Use a custom session to create a data container object that shares ActiveX objects you create or other data between software components you write. Use the Attach and Get methods to attach data to and retrieve data from a session. A custom session does not initialize, close, or own an instrument handle. The data you share with a custom session does not have to be instrumentation related. You can create a custom session with any name you request.

How can I pass in continuous value from labview to teststand?

Hello
I want to run a vi using teststand. I want this vi to send values to teststand. My problem is that the value is only updated at the end of the vi execution and I want to get the value before the end of the vi execution. If somebody can help me ...
Thanks
Corentine

Corentine,
you can think of TestStand calls to LabVIEW-VIs just like functioncalls in C/C++. The main continues running only if the subroutine is fully executed. Furthermore, LV returns values to the parameters (connector block) only at the end of the execution of the VI.
So you cannot use "simple VI calls" in your sequence if you need datatransfer during execution from steps. If you like to do something like this, the easiest way would be to create a VI which runs continuously in the background and supplies data via mechanisms like Queues (if executed in the same instance) or TCP/IP. In the stepmodules you can retrieve the data when needed.
hope this helps,
Norbert B.

Multi-Threading in Labview (not teststand)

I have heard that it is possible to write a Labview application using
more than one execution thread, but I don't understand what the help
files are saying.
Do I have to have a HyperThreading CPU to do this?
This was easy in CVI.
Can more than one thread make changes to the front panel controls or even display it's own panel?
Maybe someone has some pointers or simple examples of how to create a second thread.
(Please - no TestStand examples. Just 100% Labview)

You don't need hyperthreading. Parallelism is built into LV in several levels. First of all, you can simply have parallel code by having 2 pieces of unconnected code which will run "in parallel" (the scheduler will make sure they both get executed).
You can assign priorities and threads to VIs by going to File>>VI Properties>>Execution, but there is usually no need to deal with this because is LV will be fast enough without this (plus, you have to know what you're doing).
Like I said earlier, if you just want different pieces of code to execute in parallel, just make sure they are not connected. You can open as many VIs as you like like this and let them execute in parallel. You can have seperate loops updating controls on the same front panel. Basically, whatever you like. It's really very simple. If you want an example, simply create 2 while loops which do something, and you can see they do it the same time.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

How to use Expression Edit in the LabVIEW control (teststand category)?

Hi All,
I am developing the teststand specify module using LabVIEW. I found that is Expression Edit control in the Labview Controls pallete. does anyone have any example?
I have enabled the expression browser button but I dont know how to link it to the teststand. Pls advise.
Thanks

Hey Toko,
You basically need to refer the button to the sequence context. For a great description of this and an example, please refer to this previous discussion forum:

What are the current versions of Labview and Teststand

Hello,
i am currently downlading the current versions of teststand and labview for evaluation.
In the Teststand-link i saw that it is called "Teststand 2012".
1. But there was no version-information in the Labview-Download. Is this also version 2012?
2. Are both things 32-bit-software?
3. After i installed the evaluation-downloads - can they be activated with a key or do i have to install it again when the CDs arrive in my office?
Thanks for help

Thx for the links.
I am using Windows-7-64bit - should i prefer then also Labview 64? (The NI-download-Links only provides 32bit for download)
Will there be any problems converting my existing Labview 8.5-Vis to the new Labview2012?
Thank you
You can have both the 32-bit and 64-bit installed. Just remember your target when you build an exe. 64-bit compiled programs can only run on 64-bit machines.
You should have no problem upgrading your code from 8.5.
