NI TestStand

[Alex_Haak]

I am using TestStand to communicate with a device which tests itself. TS simply makes a DLL call which through a serial channel finds out how many errors the device has had for each test (e.g. ethernet). This needs to be continually for each test for about 3 days. Whilst i realise that this is not the manner in which TS is meant to work, due to the back-end already being finished i just simple have to make do.

My question is:

What is the best way to organise the test steps (DLL calls which return the number of errors) and the results? I have considered just looping through a test sequence but this would result in millions of individual results in total? Is there someway of updating the same result for a step when it is called 1000's of times?

Thanks

Add each error to a variable in a loop that runs for 3 days. Record the variable data to the report at the end.

If you want only the cumlative value the variable method is fine.

However if you want to store each error values@specific time then you can think of enabling the database.

It will automatically store the required values for you.

Thanks, i will probably use variables. I really need to know when an error occured for the first time but ill store that in a variable aswell.
