How to synchronize the number of samples of the motor position and DAQ values

[Kindly-Wisher]

Yes Dennis_Knutson,

I am saying exactly that. As you see from here i connected the loop's iteration constant to the TDMS file, and i read "1"(loop iteration constant)  ,  4 times per second.

Thank you for your consideration.

Best regards.

That link does not show anything of the sort. That link shows a VI with a DAQmx function and the motor controller read. Nor does that link show the iteration terminal connected to anything at all.

I have no idea what you have actually done. If you are going to make references to modified VIs, post the VI or at least an image of it.

Dear Dennis_Knutson;

there is loop iteration constant at the right bottom side of the picture. (next to the loop's stop button). This constant is connected to the TDMS after  "initialize array" function.

So what. What do you think that is supposed to prove? All I can tell is that I seem to be wasting time on understanding experiments of yours that do not do anything at all.

Hi Kindly Wisher,

Are you trying to test what I said "Super easy test would be to replace the Current Position output with the iteratation count of the while loop.  I'm betting that the TDMS iterates up one at a time. "

If so, I think you are mistaking what I meant by the iteration count.

That's what I wanted wired in, not the "1" constant.  The point was to show you that you weren't losing data and that the file would have "0,1,2,3,4,5..." in it.

Does that make it more clear?

And indeed you are still reading and that reading is the limiting part.

Throw out all the daqmx

throw out the tdms

and just look at how fast you can read positions.

That stays 4 or 5 pieces per second so that is and stays the limit.

good luck and find another job.

Dear Justin_P,

Yes i misunderstood what you had said me before. I am sorry about that.

Thank you all for your answers. Then it is clear that the SMC100 is a slow communicator.

Kind regards from Turkey.
