Best Way To Collect Production Data and Compare Against Limits

[testdesign]

During production test, what seems to be the most efficient way for collecting lots of test data and then checking each one against limits?  I'd like to hear the LabVIEW community thoughts.  Thanks!

Hmmm that's a rather vague and open ended question....

Do you mean realtime limits as in pass/fail testing or aggregates like production yields and first pass test failures?

[testdesign]

Great question RTSLVU, I am actually looking at both:

1. Real Time Display of data on UI - With data read, test limits, and whether the data read passed withing limits

2. Data Collection Into Report File - Shows data read, limits, and pass/fail as well but all this test data is included in one file

Thanks!

All these are the standard features of TestStand, are you trying to recreate a sequencer?

I recommend using a production database.

Retrieve test spec data by keying off: DTU_P/N, Test_Name, Step_Name, Parameter.

Data retrieved would be: Lower_Limit, Upper_Limit, Comparison Type, Abort_on_fail.

@Santhosh,

My requirement is not to use TestStand, only LabVIEW.  I understand TestStand capabilities.  I'm just looking for information specifically using LabVIEW only.  Thanks.

Can you elaborate more on your question ?

The answer varies depending your constrains: 

- The amount of data. 

- How fast you need the result 

- Depending on the result (pass/fail) does the operator need to intervein ?
