TESTSTAND 4.1 VERY UNSTABLE COMPARED TO TS4.0

[Josh_W]

Rafi,

You can check if the patch is installed by going to Help»About in the LabVIEW environment.  It should say 8.6f1 as the version in the lower-right corner if you have installed the patch for the development environment.

Verifying the patch for the runtime engine is a bit more difficult.  You need to go to <National Instruments>\Shared\LabVIEW Run-Time\8.6 and find the files named lvffrt.dll and lvrt.dll (they should be the largest files in that folder).  If you right-click on them and select Properties, you can go to the Version tab and see the Description of the file.  That Description should read "LabVIEW 8.6f1..."

Let me know what you find.

Hello,

I'm having the same problem with Labview steps taking up to 10 seconds to load in TestStand, but in my case I have installed TS 3.5 and LV 8.5.
I there a patch for this revisions?

Thanks,

Claudio

Hi Claudio,

There are no known TestStand 3.5 and LabVIEW 8.5 compatibility issues. Could you provide further detail on the behavior you're experiencing?

Do you have the LabVIEW Adapter configured to use the Development Environment or the Run-Time Engine? Are you experiencing this during edit time when browsing to a VI in the Sequence Editor? Are you experiencing it when you simply select a LabVIEW step in the Sequence Editor? Is LabVIEW initially open or closed when you experience this behavior? Are you experiencing this during execution of a sequence? If so, what are your step Load/Unload options?

Do you have the LabVIEW Adapter configured to use the Development Environment or the Run-Time Engine? Usually on Development Enviroment, but has happend on both.

Are you experiencing this during edit time when browsing to a VI in the Sequence Editor?

It happens every time I change the selected step in the Sequence Editor, it takes like 10 sec to load. Meanwhile if I try something else teststand is not responding. I have to wait for the step to load.

Are you experiencing it when you simply select a LabVIEW step in the Sequence Editor? YES

Is LabVIEW initially open or closed when you experience this behavior?

I happens in both scenarios. I think is expected if LabView is closed it will take more time to load, but I guess it should be only in the first time.

Are you experiencing this during execution of a sequence? If so, what are your step Load/Unload options?

No, is during sequence edition.

Also I've seen sometimes it works smoothly, but then it gets all slow (even with a restart of TS and LV). Other times starts slow and stays that way.

I've been working on the same test sequence for days now, all step are LV steps or call to subsequence.

Other programs running on the backround are the usual Outlook and Firefox.

Thank,

Claudio

Claudio,

Thanks for that information. In TestStand 3.5, clicking on a LabVIEW step does not load the VI into memory. I'm assuming you experience this behavior when you right-click the step and select Specify Module. Is this correct?

When you experience the "slow loading" after selecting a LabVIEW step, does this always occur when selecting the same step or many different steps? If many, are the steps calling the same LabVIEW VI or different LabVIEW VIs? If the steps are calling different LabVIEW VIs, do these VIs have anything in common, particularly with the inputs/outputs wired to the connector pane?

This happens when changing from one step to another and also backwards (I mean, even if it was loaded before). I call diferent VIs, all these have at least 2 inputs and 4 outputs (in: obj Sequence context, cluster Error in; out: cluster error out, obj seq context out, numor pass fail Result, str comment) some VI has have more inputs. All VIs in sequence are top VIs, each with subVi calls.

Claudio

Claudio,

Unfortunately I am still unsure of the exact behavior you are experiencing. What do you mean when you say that you go from one step to another? Do you mean simply clicking the step or right-clicking the step and selecting Specify Module? Also, Could you describe exactly what you mean by "slowing down"?

Perhaps a screenshot taken while TestStand is "slowing down" or hanging might be helpful to display the behavior.

[AlphaKane]

I mean by simply left-clicking the step. By slowing down I mean: during the time TS is loading the step, TS is not responding; if you click somewhere else the TS window paints white and only the window borders are drawn.

I hate to say, right now I'm not been able to duplicate the problem, but last 2 weeks this has been a pain for my development.

Regards,

Claudio

If you do experience the behavior again, please take a screenshot during and a screenshot after the sequence editor turns white.

Hi Josh

I have shifted to TestStand 4.2 with LabView 8.6.  Is the patch still necessary?  I'm experiencing slow operation of TestStand after it has been working for some time.   The Windows Task Manager show 50% busy for TestExec.exe.

Is it possible to set it higher, so it can run faster?

Thanks
