VeriStand Steps for TestStand Feedback

[Sarci1]

Sorry Jimmy that response was for Apeksha. Which RT Sequence step are you saying has this behavior?

[Jimmy_Zhao]

Hello Sacri,

There are two issues with RT sequence calling:

1. Parameters passing by value – I Define a Double para. “voltage”, enter a number of 4.32 at the configuration window, however, the RT sequence results shows it takes as 4.

2. If I add a step “WaitUntilSettled” in RT sequence, when running to the step calling this RT seq, it seems stay there forever.

Thanks,

Jimmy

Hello Sarci1,

I got this error if I put a file name Test1.tdms, which doesn’t exit.

[Sarci1]

Yes, I understand the problems you are encountering but I'm asking which RT Sequence step you are using - RT Sequence Pass/Fail, RT Sequence Numeric Limit, or RT Sequence Action?

[Jimmy_Zhao]

Hello Sarci1,

It’s RT Sequence Pass/Fail

Thanks

Jimmy,

1. TDMS Error - This error is generated by the Sequence Analyzer. There is a known issue with the analyzer where it returns errors with certain path types (see Known Issues section of the VeriStand Steps for TestStand page). The workaround now is to disable the Sequence Analyzer in TestStand.
2. Parameters to RT Sequences - I looked through the code and there is indeed a bug in the RT Sequence step which improperly converts the Double to an integer. This bug will be addressed in the next release of the steps. Until then I can instruct you on how to fix this bug in your system if you have LabVIEW on the machine.
3. Wait Until Settled Hang - I attempted to replicate this myself and was not able to get the TestStand sequence to hang with an RT Sequence that included Wait Until Settled step. Do you know if the step is timing out or if it has actually settled?

Thanks Sarci1!

Please see below:

1. Yes. It works by ignoring the error.

2. I have LabVIEW 2014SP1 installed.

3. I am not very certain. It should be settled before timeout, as there is no problem when calling the same RT seq from stimulus profile.

Hi Jimmy,

With TestStand closed, please extract the RTSequenceVIs.llb from the attached *.zip file and place it in your<Public Documents>\National Instruments\TestStand 2014 (32-bit)\Components\TypePalettes directory to overwrite the llb that exists there. This should resolve the Double issue.

Best Regards,

Lynn

Hello Lynn,

I do not see a zip attachment with the message.

Thanks,
