TestStand not passing VISA info to LabVIEW

Hi All,
I am encountering a problem passing a VISA resource name to LabVIEW (2014) from TestStand (2014) which I cannot for the life of me understand or solve. Thus and so, I would be exceptionally grateful for any help.
I have two Thurlby Thandar LXI power supplies in a test rack, each with unique IP and socket addresses, of the form (TCPIP0::192.168.0.3::9221:OCKET). I have a LabVIEW project which contains a number of VIs, each related to the various functions of the PSUs, which are called from TestStand as appropriate.
I'm calling the LabVIEW 'Initialise.vi' in TestStand within a "ForEach" loop to individually extract the PSU's addresses from an array, open a session, then store the SessionNumber, but the resource name data doesn't seem to make it through to the VI's front panel VISA control. I've checked, checked and re-cheked that the correct values are being pulled from the array, I've even tried putting the LabVIEW call in a sub-sequence, just so that I can verify the data is not being corrupted in any way, but all seems to be well. It's as if the link between TestStand and LabVIEW is somehow broken.
To clarify the issue, on the very first run, the VISA information does get through, but subsequent runs retain this value, rather than overwriting it with the next value in the array. Setting the Run Options of the LabVIEW Action step type to Load Dynamically then Unload after step executes overcome this issue, but cause problems when trying to control the PSU later on in the test sequence.
The most maddening thing is that this used to work up until a couple of weeks ago, but unfortunately I can't remember what, if any, changes I may have made.
I've reinstalled TestStand and LabVIEW, but it hasn't solved the problem.
I've made the VI re-entrant, but that doesn't make any difference (in truth it shouldn't, as although the VI is called numerous times, all calls are sequential rather than simultaneous, so re-entrancy shouldn't be an issue).
I've configured the PSUs in MAX and given them aliases and tried the addresses direct, but that makes no difference either.
I've also tried performing the same exercise of passing data to LabVIEW just using strings and that all works fine, it just seems to be an issue with VISA resource names.
I have a suspicion I've checked or un-checked a check-box somewhere in the bowels of TestStand that's causing all of this, but haven't a clue how to find it.
If anyone can shed some light on this why this issue is occurring, or could even just point me in the direction of some utility which could sniff dataflow between TestStand and LabVIEW, I would be very grateful.
Many thanks in advance

Personally, I use Action Engines to handle my instrument resources. You can call the AE directly in TestStand. What I typically do is have a string input for name and then do a quick lookup for the desired VISA Resource to then control the instrument. This keeps all of the VISA stuff (including resource references) in LabVIEW. Have never had a problem with doing it this way.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

TestStand - Call Package VIs for Distribusion.vi is not executable

I am trying to assemble my VIs for Run-Time distribution using the TestStand tool. How ever on selecting the Run-Time distribution option, the following error is displayed
"An error occurred in the 'Package VIs' step of the 'Package VIs' sequence in 'VI Packager.seq'.
LabVIEW : VI is not executable.
An error occurred accessing the LabVIEW ActiveX automation server. Error Code: -18001"
On oppening the vi (TestStand - Call Package VIs for Distribusion.vi)it was seen to have brken arrows. The problem appears to be located in the sub vi, TestStand - Build dist for TestStand.vi which is password protected. Could this be a problem with my ActiveX connection(TestStand is using the LabView standard prototype Ada
pter with the LabView Development environment serving as the ActiveX server.The sequence I am trying to package runs successfully under these condisions)?

Hi,
One of the things you need to do is to ensure all your vi's are at the same version of labview. All TestStand assoicated llb's and Vi's are at version 5.1.1 when you first install it.
Therefore, if you have updated your labview, you will need to mass compile the TestStands folders.
Also, check the Updates for TestStand, http://digital.ni.com/softlib.nsf/954feaeea92d90918625674b00658b83/e047ebba4b45a98786256949007bc2a7?OpenDocument this may or may not affect depending on what TestStand and LabVIEW versions you are using.

LabVIEW 6.1 If For Loop count terminal is zero then value going through the loop is not passed on to the output of the loop

Hello, one of our customers just encountered an execution error in a vi running under LabVIEW 6.1, which doesn't exist under LabVIEW 5.1 or 6.01. I have a simple vi that has two encapsulated For Loops. Two string arrays go in, one goes out of the outer loop. Inside the outer loop the first array is indexed. The string which results from this indexing is compared with all other strings from the second string array in the inner loop. If it matches one of the strings of the second array, it is not outputted, otherwise this string goes through the inner For Loop to the output of the inner loop and from there to the output of the outer loop. The count
terminal of the outer/inner loop is connected to the Array Size of the first/second string array. If the second array is empty, that means that the element in test from the first arry cannot match anything from the second array, so the element in test is send to the output of the inner loop and from there to the output of the outer loop. This works fine in LabVIEW 5.1 and 6.01, but NOT in LabVIEW 6.1. In LabVIEW 6.1 the inner loop is never executed if the count value is zero (which is correct), but the data line running through the loop is not executed either, which is different to what LabVIEW 5.1 and 6.01 do. There, the input string is sent to the output of the inner loop correctly even if the loop counter is zero. The solution is easy - I just have to connect the output of the outer loop to the data line BEFORE it enters the inner loop. But: I don't know if this is a LabVIEW 6.1 bug or if it is supposed to be a feature, but it brings some incompatibility in programming between the
different LabVIEW versions.
Best regards,
Gabsi

Hi,
When a for-loop runs zero times, all outputs are 'undefined' (and should
be).
Besides, how would LV know what the output of a not executed routine should
be?
It might be handled differently in LV5 and LV6, which is unfortunate. In
both cases, the result is undefined.
It's not a bug. It's just something that should be avoided in any LV
version.
> The solution is easy - I just have to connect the

In some cases this does the trick. But if the data is changed in the inner
loop, this will effect the results if the N is not zero.
Technically, I think the output in this construction is also 'undefined'.
But LV handles this as expected / desired.
Another solution is to use a shift register. If N is zero, the input is
directly passed through to the output.
Regards,
Wiebe.

Saw this solution on another post about an iPad in a school enviroment. Might work on your iPad so you won't lose everything.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just cancelling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

HP4275A can not pass self test after running the labview program

I am using Labview to control HP4275A LCR meter. The Labview program is just the instrument driver for the HP4275A, and it works great. Before running the program, the instrument can pass both Open and Short test perfectly. But after running the program, it can not pass self test, neither Open nor Short. I don't know why?? Is it relative to my Labview program??
Thanks

Thank you so much for your help. Yes, the instrument is in Local after running the instrument driver. In normal Open self test, just choose Capactiance as the Display A, and leave the four output terminals open then press the Self Test button. The Open self test will start and "OP" will be shown in the DIsplay A window, after 2 seconds, the open test will be finished. If something abnormal, the number of the abnormal step is displayed in Display A. Similar with the Short test.
The problem I had was: before running the instrument driver, the self tests pass; but after running the instrument driver, the Open and Short test show abnormal, Open test is abnormal at step 17, and Short test is abnormal at step 24.
And the instrument driver is only write commands into the instrument and then read back measuring values from it. Nothing else. So I am not sure if the problem is my instrument driver.
The weird thing is the problems happened several times and then if I do the Open and Short self test again after running the instrument driver, both pass. I am not sure whether the problem will come back or not.
Ia there any help??
Big thanks

Just to recap, this is a collection of ports I have collected over time for people who needed this information when setting up the HP ePrint app so that they could view their email from within the app. I am certain other applications also need this information. Although lengthy, I could not find a more comprehensive place to retrieve this information. Feel free to post additional information, faulty information, or other related topics below as this is simply a collection of data and it would be practically impossible to test all of them.

When I run this VI "Waveform Time to Date Time String" in LabView 7.0 it will not pass decimals of seconds.

When I run this VI "Waveform Time to Date Time String" in LabView 7.0 it will not pass decimals of seconds. From decimals of inputline. If i disconnect the input to the subVI "Get Date/Time string vi" it will work propperly, it also doses if I reconnect it. I use LabViev 7.0.
So the problem i solved, but i dosent understund why it works in this way. Does it indicate other problems which will make my researchprogram unrelaible ?

Hello.
I checked your vi and it fails as you state.
It runs fine if: 1 Convert number to timestamp OR
2 Wire a constant to want seconds?
In labview 7.1, no problems.
I think is a job for NI engeniers.

Teststand automatic test report printing using LabView workaround

I tried the LabView workaround for the automatic printing of test reports in TestStand (see email message below).
It will work if I set the URL to a specific HTML TempReport. However, TestStand is configured to generate a unique test report for each UUT. So, in the test report directory there are xml reports and the occasional HTML report, example TestReport_00104.html. Not sure then what to set the URL to?
Note: Your reference number is included in the Subject field of this message. It is very important that you do not remove or modify this reference number, or your message may be returned to you.
Hi Bill,
Thanks you for your reply.
Right ok. Well, if you are interested in the LabVIEW workaround, I can send this to place it in your modified sequential model.
The workaround works as desired. It does it all automatically. I have set it to not prompt the user for the print dialogue but this can be easily changed. Therefore, for any example program in Teststand, if it is based on the modified sequential model, an HTML style report will be printed on the default printer automatically.
It needs to be placed in the following location:
Within the Sequential Model, within 'Single Pass>>Print Report' do the following:
- Replace all the 'Main' steps (Navigate to HTML, Print HTML File & Close IE Browser) with the LabVIEW function call.
- This one function call will do all the steps above at once.
NOTE: In the LabVIEW VI, you will need to select the correct directory where the new html files are being created. Otherwise the print function will not work. This is called URL. Make you sure you have checked this.
For ease of understanding I have included these steps in a word document with screen shots.
As I do not know which version of LabVIEW you might have, I have attached three versions of the .vi file; 2012, 2011 and 2010.
In regards to the mention of Teststand not having built in functionality for automatic printing of reports, unfortunately this is the case.
I hope this will be a sufficient workaround for you.
If you problems implementing this solution, please ask me for further information. However, it should be fairly simple to do.
Just to inform you, I will be out of the office from 12.45pm today for the rest of the week on annual leave.
I will be back in the office on Monday 14th January 2013, should you have any further queries.

Print HTML file from LabVIEW.zip ‏39 KB

Hi Bill,
I managed to implement this.
In the sequential model I added a LabVIEW action after 'Add Root Tags To XML Report'
As URL I use a sequence local: Locals.ReportFilePath
I points to the ML report in my case and then the VI works fine.
However I'm looking for extra functionality and that is waiting untill printing is completed.
Can you help me on that ?

Pass VISA resource to DLL created by CVI

Hi, I want to call a DLL created by Labwindows CVI in Labview.
When I use ' Call Library Function Node', I have to define the parameters output in DLL. However, there is one 'VISA Resource' type parameter and I don't know which shoudl be the right in Labview's definition.
Anyone can help about that? Or maybe there are some easy way to do this?
The type in CVI is: 'ViSession g_hSA'
Thanks in advance.

There are several issues here. First, a VISA Resource (or other string name resources in LabVIEW) are really a combination of a name and a session ID. If the session ID is invalid, LabVIEW will automatically open a session ID using the string name based on the refnum type. Obviously this won't work in a C function interface anymore as one does not have access to the low level C APIs in the LabVIEW kernel to treat the LVRefnum in such an dual mode way.
What does work is to pass the string to the first function as C String, and do an explicit VISA Open there, then return the VISA session to the caller as LVRefnum and treat it from there as such.
The LabVIEW Call Library Node does a few intrinsic conversions based on the configured datatype.
If you configure the parameter as String, LabVIEW will pass the resource name to the DLL function.
If you configure it as (U)Int32 (and in fact more precisely as pointer sized integer), LabVIEW will extract the underlaying ViSession from the VISA library and pass that one. You should use pointer sized integer instead of 32 bit integer, since a ViSession is really equivalent to a pointer and therefore would be 64 bit large in 64 bit LabVIEW.
If you configure the parameter to adapt to type, LabVIEW will pass its own VISA refnum to the function. This refnum is a LabVIEW intern entity, (and alwasy 32 bit in size and only valid inside the LabVIEW session who created it) and really wraps the ViSession into a LabVIEW refnum for internal bookkeeping reasons.
However the original post also shows TD1 errorIn and errorOut datatypes. This looks suspicially like an error cluster and that would be a thing that you can not easily create in non-LabVIEW land in a way, that LabVIEW will not crash when trying to access it.

No VISA Resources in Labview but all present in MAX

Hi,
I am unable to find any VISA resources from LabVIEW, however, all NI hardware is available and working in MAX. I have just installed a PCI-8433/2 as well as a NI PCI-8512 CAN/HS Card. As part of the installation I believe MAX was upgraded to version 4.6.2. I will attach the max configuration report for those who are interested. I am working with LabView 8.2. I also uninstalled an agilent GPIB card and as a result the NI-GPIB card is the sole controller and is GPIB0... instead of the agilent card.
I have had a similar problem before that was a result of a corrupted database, but I was unable to find this problem on the forums this time and I am not getting any errors. Just an empty VISA Resource control.
Any suggestions would be greatly appreciated.

Now that IS odd.
Can you show a couple screen shots from MAX?
First expand the software tab and post a png of the screenshot (I'm not yet convinced you do not have SOME driver issue)
Next select MAX>TOOLS>NI VISA>VISA Options- Wait for the new screen then expand Mysystem General settings and select Aliases.
You could also try "Clear all aliases" from there and reboot.

Lbplugin not passing pages that end in .html through

Hi,
We are running SunOne 7.0 U2 webserver with the installed lbplugin for SUN Appserver (Glassfish). I've set up the loadbalancer.xml to pass the context root through to the appserver cluster, but any page in the war file that ends in .html is not passing through, but throwing a 404 error. It looks like the web server is looking locally for the files. I've tried everything I can think of to force it, but not sure what else to do. All images, etc. come through fine - just files ending in .html don't.
I've made sure the plugin is at the top of the magnus.conf, the NameTrans directive is the first one in the server-obj.conf file, etc.
Thanks!

Thanks, tried that, but the same behavior persists. The log shows that the /ac2 path (weblogic) gave a 404 not found because it was handled by the JSP engine. Local JSPs work (this is with the ntrans-j2ee still in the default block).

[15/Aug/2008:15:27:58] fine (14584) glassdev: debug reports: BXKhSo to test what I experienced with files ending in .html searching the server root instead of the doc root (which is why I added the htdocs object block), I created the directory structure off the root of the system and put the text "test" in the perlBody.jsp file:
bash-3.00# pwd
/ac2/wp-dyn/jsp/enc/html
bash-3.00# ls -al
total 6
drwxr-xr-x   2 root     root         512 Aug 15 15:36 .
drwxr-xr-x   3 root     root         512 Aug 15 15:36 ..
-rw-r--r--   1 root     root           5 Aug 15 15:36 perlBody.jsp
bash-3.00# cat perlBody.jsp
test and hit the URL again and what should appear in my browser? Not a "not found", but "test". So this definitely looks like a bug in both the SHTML processing and proxy plugin processing.

Why am in not getting a picture in LabVIEW?

The problem that I am having is that I get a picture in MAX but I do not get a picture in LabVIEW. I can't even get any information comming in on the U8 pixel readout. Nothing seems to come in. I don't know why. I have a KLI-2113 Tri-linear image sensor. It is a line scan camera. I can see that the IMAQ board is doing something because if I don't have it on and I try to start the VI "Acquire Image and Save Pixels Without Vision.vi", I get an error, no external pixel clock message. I know that it recognizes the board. I don't know why I get an image in MAX but not in LabVIEW. Can anyone help me out?
Thanks,
Brian

You mentioned that you are able to acquire images in MAX, but not LabVIEW. What type of images are you looking at? Are they 8-bit or 16-bit? The issue may be that the image comming in from your camera is 16-bit, so no info would be displayed for the U8 (8-bit). Try the attatched example and see if you have any better luck- It allows 16bit images as well. If your image comming in is 12, or 10 bits, it is still stored as a 16bit image, but it is stored as the lower bits, so it may be necisarry to shift the bits as well.

Vernier labpro VIs designed for labview 6.1/7.0 using them in labview 8.5

Hi
I have downloaded the labpro toolkit and mass compiled them in labview 8.5.I wanted to store the vernier sensor data using labview, however the analog data collection VIs are for Labview 6.1/7.0.
The computer restarted and labview stuck when I tried to use the VIs.
How can I read data and save/store it for further analyses?
What should I do?
Is there any compatible VIs that will run without any problem , should I download patches or any labview version?Does vernier have a solution?
I am looking forward to hearing from U.
Thanks

I looked at the drivers from their web site and the code structure (as you would expect) pretty much sucks and the serial io routines need to be updated to get
rid of all the compatability VIs, but right off hand I don't see
anything too dire. The one exception is that if you are using the USB
interface access is through a DLL that they wrote - that could be a big
problem. A lot has changed since 2003.
How are you interfaced to the device? USB or Serial? What OS are you running? Did I understand you to say that the computer crashed? What do you mean by LV "stuck"?
