Simple Teststand UI API for LabVIEW

Like many people I know how painful it is to program a Teststand user interface in LabVIEW.
To combat that I have developed a new API which wraps the ActiveX calls into modern object oriented code which follows proper LabVIEW programming paradigms.
Please check it out:
https://decibel.ni.com/content/docs/DOC-43511
This is pretty much beta software, so constructive feedback on the code or the article itself is greatly appreciated.

Hi holy,
I am not familiar with that instrument, but looking at the spec, it doesn't look like its compatible with IVI.
The product spec says it comes with a driver for labview and probably some example VI's.
Therefore to interface with TestStand you will have to use the LabVIEW adapter rather than the IVI step types.
If you are using TestStand 3.x, then you should be able to interface to the individual driver VI's or create your own higher level function VI and call these using the LabVIEW Adapter.
The driver doesn't appear to be available as a download from the NI website, otherwise I would have created an example sequence file for you.
Hope this offers some help.

Using TestStand Engine API in LabVIEW

Hi all,
I am currently working for a proejct where automation of testing is involved, For which NI LabVIEW and TestStand are used. My previous experience is in LabVIEW only and not in TestStand. In the current project I have to develop a UI where user can select the test sequences and execute them automatically with a simple start command. So I thought to develop a UI in LabVIEW where I will call TestStand APIs in LabVIEW. I have a developed a code by calling the TestStand APIs and able to execute the sequence, but unable to generate the report. Does any have stuff where in TestStand APIs are called in LabVIEW and test report is generated.
As I mentioned earlier I haven't worked much in TestStand. I have gone through the TestStand examples like Simple UI. But it didn't helped me much.
To put our project requirement in simple.
1.It should have the UI to select the TestCases (Test Sequences) and an option to select the no.of times the test cases needd to be executed.
2. It should generate the reports for all the test cases.
3. UI should support localization.
Considering the above requirements I have thought to develop UI in LabVIEW calling the TestStand APIs. I also got to know that UI can be developed using TestStand, but I am not sure whether the above mentioned requirments can be fullfilled or not.
I am attaching the VI what I have developed in the LabVIEW with which I am able to execute the sequences, but unable to generate the report. Kindly look into the VI and let me know what need to be corrected to generate the report using the same VI.
Thanks and Regards

If you want to generate a report you'll have to choose an entry point. You should have a look at the LabVIEW OI (operator Interface) shipped with TestStand

Can a "object reference" type from TestStand be used for Labview VIs

I am creating a test sequence in Test Stand and I am looking to use a "object referrence" type stored in the globals of TestStand as an input to VIs that I will use later in TestStand. The object can be from .NET or ActiveX. I need to know if I can use a input that will support either type.

Hi Mcfrenzy36,
Object references can be used for LabVIEW. I have found an article that teaches how TestStand handles Activex object references. Here is the linkt o it:

Teststand API in LABVIEW

Hello Friends,
In the sequence editor , i am able to get the TestStand API RunState.Step.Module.AsLabVIEWModule.RemoteHost = ""
But i am not able to get the same Teststand API properties in Labview with sequence Context. Herewith in attached the image for your ref.
Anyone knows how i can get the above teststand API in LABVIEW.
Thanks

Hi Prithivi,
you have to cast the Module Reference to LabVIEWModule Type before you can use it. Following document will be useful to you:

Aeroflex 2975 driver for LabVIEW 8.0

Is there a way to convert the Aeroflex IFR 2975 driver for LabVIEW CVI for use in LabVIEW 8.0? OR, is there a driver already developed for this?

Frank,
I am using the LV 7.1.1 version of this CVI driver in an application I wrote. We should be able to recompile this for 8.0. Basically as I explained with no handshaking the instrument falls out of sync with the controlling computer. Basically the only GPIB command that is supported in that driver is *IDN?. So what I have done is after other calls I use this command and compare the return string to see if it is what I expected. If not I use a popup telling the operator that a GPIB error occurred and to reboot the IFR to clear the bus. I also have instructed the operator to run NI Spy in the background...this seems to cut down the occurance of these errors. Another way to clear the bus that is faster and usually works is to stop the application, and read the bus using MAX until you see a timeout when there is no more data available( usually twice). Then rerun the application. Depending on the application this might be a work around though not an elegant one.
Since the driver was converted from a CVI driver it uses the call library function node. This does not allow us to control the timing between the Write functions and Read functions. If you are doing something that is relatively simple you could use the TCL command set and VISA to write a driver. Just put a wait function between the Write and Read function and experiment with the timing until it looks like it won't fail. I've considered doing this myself but have been hoping that they will actually make the instrument 488.2 compliant. I am assuming that the actual error is that the data buffer is being read by the controller before the instrument is finished writing to it. The other scenario is that the data buffer might not actually be getting flushed every time it is read. I'm hoping my first assumption is correct or they have even more problems with the instrument.
In January of '05' they actually enabled the following commands *SRE xx, *SRE? and *STB?. I recently wrote a simple vi to see what happens to the Status Byte after using IDN? command and reading the data buffer. The MAV bit begins logic low, then goes hi when the data is available. After reading the data (i.e. "IFR Systems, 2975.....) I again query the Status Byte. The MAV bit is still in a logic hi state. I sent screenshots of the front panel and block diagram as well as the .spy files to them. All was heavily notated and they said they were going to look at it. If anyone is interested in this I can post this code as well.

Java API for running entire ".sql" files on a remote DB ( mySQL or Oracle)?

Hi,
Would anyone happen to know if there's a java API for executing entire ".sql" files (containing several different SQL commands), on a remote database server ?
It's enough if the API works with MySQL and/or Oracle.
Just to demonstrate what i'm looking for:
Suppose you've created sql file "c:/test.sql" with several script lines:
-- test.sql:
insert into TABLE1 values(3,3);
insert into TABLE1 values(5,5);
create table TABLE2 (name VARCHER) ENGINE innoDB; -- MYSQL specific
Then the java API should look something like:
// Dummy java code:
String driver="com.mysql.jdbc.Driver";
String url= "jdbc:mysql://localhost:3306/myDb";
SomeAPI.executeScriptFile( "c:/test.sql", driver, url);
Thanks.

No such a API, but it's easy to parse all sqls in a file, then run those command:
For instance:
import java.sql.*;
import java.util.Properties;
/* A demo show how to load some sql statements. */
public class testSQL {

Java API for Adobe Flex(AIR and Browser)

Hello Community,
Sometime ago i started the project located at: : http://code.google.com/p/gwt4air/ , wich primary goal was to bring another approach on writing AIR application by providing a Java API for the AIR API. On top of that i added support for PDF and Excel generation using Java.
I m glad to announce that the project will now add support for the Flex Framework
I wrote a post about it on the main page.
The Idea behind it is to give Java Developers a more simple way to write Flex Application by leaveraing a swing like API.
I hope this project will be a good alternative to the MXML+ ActionScript approach and looking for people willing to join the project.

Functions in IMAQ Vision for Labview same as those in Vision Builder?

Hi all...
i just have a simple question..Does IMAQ Vision for Labview has the same functions of Vision Builder?
I know that with Vision Builder you can develop an application interactively...but does it has more functions than IMAQ Vision?
So if i buy IMAQ Vision can i develop the same kind of applications that i would make with Vision Builder?
I´m specially interested in color matching and color analisys functions.
Thanks

IMAQ Vision has much more than Vision Builder. Basically, VB was created using Vision and they implemented a good number of the functions in a menu driven format. However, there are many more functions available that were not integrated into VB.
Vision does have some good color matching and analysis tools.

Teststand 4.1 and LabVIEW 8.6 taking more time to launch?

For lauching the LabVIEW 8.6 steps in TestStand 4.1 its taking almost 7 to 10 seconds to load or refresh the LabVIEW terminals. Everytime while clicking on the LabVIEW steps its taking the same time..... Its a kind of irritating to write code in TestStand. I dont know what happening inside.. but in TS 4.0 its pretty fast. Even I tried with using runtime engine option.... very little bit of changes I found... in this case I cant able to edit the LabVIEW code.
Is there any method to make it faster to repond. Or its because of LV 8.6 the way it loads.?
Vijay

There is a known issue with LabVIEW 8.6 and any version of TestStand that will cause a significant delay updating the display after selecting a LabVIEW step in the sequence editor. The issue is described in KnowledgeBase 4PH891T3: Known Compatibility Issues with TestStand and LabVIEW 8.6, and a patch is available.
Please try to install the patch for LabVIEW 8.6f1 and see if it fixes the behavior you are experiencing. If it does not, please let me know and we will agressively investigate the issue. It would be helpful if you could provide examples or instructions to reproduce the problem.
Thanks!

Driver for MM4000 series (motion controller) for labview 6.1 (gpib)

Hello,
I need the instrument driver for a newport motion controller MM4006.
I found the driver for MM4000 series, it could be ok, but I need it for labview 6.1 and not for labview 7 or 8.
Is it possible to find this driver for older version of labview than 7 or 8?
Thanks

System Configuation API for Configuration Management

Hi all,
I've been toying around with the system configuration API for a little bit now and I see it as a great way for companies to use it as part of an overall configuration management utility. For example, if a customer wants to build up a new test rack with the same hardware aliases, configuration, and installed NI software then the system configuration API helps with most of this. I've already created a simple utility that can be used to query the currently installed hardware (of a local or remote system) and then programmatically rename the aliases based on a loaded configuration file or manual input. Likewise, the MAX export/import functionality can also be used. My application of this would primarily be non-RT and mostly PXI products but a good design could enable it to work for both.
So, my question to the community is actually on the side where I haven't used the System Configuration API yet which is querying the installed software on a system. The software querying functionality of the System Configuration API is really only geared towards RT targets and not Windows based controllers. I'd like to be able to export a list of installed software/drivers on an older system and then compare it with what is installed on a newer system to make it easier for customers to determine whether they have everything required. I know that the MAX export or report has a list of installed software but is parsing this the best way of retrieving installed software (It's a beast of a file)? Does anyone have a better method?

Solved!
Go to Solution.

Not sure if the attached VI will work across various Windows OS's since it uses a powershell command and I also don't know how well the command used will work across 32/64 bit applications...But, so far this little VI I came up with is returning the software that I want to query. Hope this is usefull for others and, as always, suggestions for improvement are welcomed!

How to prepare for labview certifications without getting training ?

Can u ppl guide me to prepare for labview certification-- the first one CLAD without taking training on labview basics.
I have learned up to certain level and made one program to manage a simple database--to enter and save new entries, retrieve them by searching using a particular item name and display it.
still I want some more practical exercises-- so that i can learn some new features too.
u please suggest me some.

Hi janki,
the best preparation is to use LabVIEW. Try to understand how the functions work. Work with Graphs and Charts. Understand how loops are working, when and why they stop and ... .
You should also use the forums search, there are a lot of threads about certification.

Problems in Operator Interface for LabVIEW

Hi Ray,
I am using LabVIEW 7.0 and TestStand 2.0 version. I am using the default operator interface for labVIEW provided in the TestStand and i am using custom step types in my sequence file.
This sequence calls a VI, which transmits strings that i specify from the serial port to the NI-7831 RIO Fpga Card for differnt baud rates. The same sequence is working fine when called from Sequence Editor but it is not working when it is called from Operator Interface for LAbVIEW. It justs either fails the test or skips them. Please tell me if there is any solution for it. I have attached the sequence file and the vi that i am calling from my sequence file.

Hi,
You forgot to attach your sequencefile and VI, but never mind.
I think the problem maybe that because you are using the default Operator Interface.
If it still the one in the NI folder, then you will have to re build the testexec.exe application using your LabVIEW 7.0 Application Builder. The default exe file has been built using LabVIEW 5.1.1
Before you start, copy the LV folder from OperatorInterfaces\NI\ to OperatorInterfaces\User.
Load the testexec.bld file in your Application Builder and rebuild testexec.exe.
Launch your new testexec.exe from the User\lV folder and retry your test sequencefile.
Hopefully that should cure your problem.

Switch Executive Libraries for LabVIEW 8.2

My company uses LabVIEW, TestStand, Switch Executive, and more. I'm in the process of setting up a new PC with LV8.2, TS3.5, and SE2.1. It seems, however, that this version of SE does not have libraries for LV8.2. There are directories on the CD for LV7.0, 7.1, and 8.0, but not 8.2. When I install, as expected, there is no option to get support for LV8.2-- only the other versions I listed. I need the nise.llb file but am not sure if I should just install the 8.0 version into my LabVIEW 8.2 directory. It just seems strange to me that the libraries for 8.2 are not there. Can someone please provide me some direction here?
I'm new here so please keep your responses at the "new college hire" level .
Thanks,
Greg

Hi TekGreg,
The attached file was written in the format of a KnowledgeBase document and details how you can use Switch Executive version 2.1 with LabVIEW 8.2. The workaround is simply to copy files from 8.0 to 8.2, but you want to make sure you copy them all. Let me know if you have further questions or if this does not resolve your issue!
