How to define a callback for Pass/Fail or Numeric Limit steptype.

[yangyang-rexxar]

I would like to manipulate the Pass/Fail step and Numeric test step result, so wonder a special callback for them, but I am not so clear to creat a callback in TestStand.

Hello paulbin

I think you should tell the members here what you want to manipulate more in detail, there are many things to manipulate.
There are a lot of "Step" callbacks. I think you could use one of them and do a wrapper that filters only the step types you want.

Hi J I propose to collect all "Pass/Fail" step result and "Numeric Limit Test" result to a CVS file on customer request withtou using TestStand report. So I would like to log the step name, high low limits values, pass or fail string. I have ever used poststep callback on this, this cause the sequence always go into the callback after every step, and then route to different case in callback but lead to low performance, the log VI resides in this callback. So I would like to get a specific callbck just only for this two steptypes. That's what I want.

 Hi Paulbin,

I have written a simple EngineCallback wrapper, i think you know this technique. I have used just only a Statement than writting to a file.

I want to figure out the performance. With/Without callback.

This is the result on 3000 steps. 13.3 s without callback and 17.4 withcallback that means 4.1s or  1,3ms more each step.

I have also tested FrontEndCallbacks which i called as an API call in PostExpression. Here you have your named callback but the perfromance: Forget it, I aborted.

So the last solution will be a Post substep call, which i think might be the fasted solution (I have to create a dll or vi).

Now i have to go to bed

Good night

Yesterday it let file run on my notebook which was very fast

Today on my "fast" development maschine it was extremly slow. I have to abort !

The reason was in StationOptions->Execution->Enable Tracing ! When i deseleceted "Allow Tracing into Pre-/Post Step Callbacks" (best all)

It was fast as my notebook!!

Hi J I'm so sorry for I can not open your file, probably caused by TS version, I get 3.1 on debug machine.
