Pass/Fail counter question. [Help]

[KowdTek]

Hello! Can someone please help me figure out how to count the # of Passed & Failed Samples below? Each test samples has to go through series of test procedure (Test - 1, 2, & 3) and I need to determine if the sample has passed or failed base on the test procedures..

Thanks!

Hey there

What are the conditions for the pass and fail and do you have a VI with a completed block diagram you could attach to your reply?

Regards

Actually I have no control for conditions, I'm just pulling the data using DB Connectivity Toolkit... The attached information is diced out from the table I've gathered from our database.

Thanks!

The OpenG Search Array will give you the indices of each, the Array Size returns a count.

Jim's solution will give the number of Pass events and the number of Fail events.  I'm thinking that the OP wants a number of samples that passed or failed, not a pass/fail count.  Look at the two indicators in his front panel picture.  A sample passes only if it passes all three tests, otherwise it fails.  I have modified Jim's code to return the number of samples that passed and failed, rather than a simple pass/fail count.

Thanks for those who replied... The last example works great but since my application will be use to a several machines I will need to define the number of test procedure (TProcedure) on each one.

Thank you very much guys!!!

Create a numeric control and call it Num Tests or something like that.  On the block diagram, delete the numeric constants with 3 in them, and wire the control to those points.  There are only two instances and they are the bottom input to the Quotient & Remainder functions.  Then just enter how many tests there are in the numeric control,

That's the plan...

Thank you...

How do you tell the difference betweeen:

• One sample failing all three tests
• Three different samples failing one test each? 

[altenbach]

If we can assume that the test are arranged in a regular pattern, three tests in a row for each sample, here's what I would do.

(Also assuming that the capitalization is the same for all "Pass" and assuming anything that is not a pass is a fail. ;))
