I am sorry that I for got to attach my LabVIEW code.
I tride to paste the picture that shows the parts about my question, but it doesn't work to post, so I also attach it with the code for your consideration. In the code, I use may sequence structures (it seems not to be recommended use frequently), because I need to wait uC and DUT processing time. It seems the only I could use. Should you have better ways to replace the sequemce structure in my code, please also let me know.
Thank you very much in advance,
