Programmatically loop through multiple measurement limit tests

[chrisludes]

Hi all,

Its pretty common for me to have to check multiple voltages on a device in manufacturing.

I'm looking for a way to create a generic sequence, that I feed a file to that, governs how many times to loop though a voltage measurement subVI.

I'd like to pass an array like this via a file.

Testname  |  Voltage Limit High | Voltage Limit Low

Item 1       |    3.2                     I      3.4

Item 2       |    4.8                     |      5.2 

Which would cause the VoltageRead.VI sequence (Theoretical VI) to loop 2 times and report a voltage each time which gets evaluated against the upper and lower limits.

I can do it in labview with teststand passing the file name to a DynamicLoopVoltageRead.VI and spit out a boolean array of pass/fail but I would like to know if there is a more elegant method in test stand.

Any help is greatly appreciated.

Thanks,

_Chris

Chris,

Does your file have to be formatted exactly like that?  If so then you will need ot a create a VI to read in the file and call it separately as an action step.  If not you can use a property object file and just use the built in TestStand functions.

Attached is a sequence that shows how to loop on a step.  Yours would of course be a VI call and not the none adapter.

BTW- your low limit is higher than your high limit... 🙂

Thanks that works.

The formatting isnt important and ill stick with what teststand loves the most.

my low limit moved to colorado.
