Labview program interface

[uranus999]

Dear all, 

I have a some problem in running my labview program.

I intention is to generate an output voltage by using my machine (by Nanonis), thus I am using their program in Nanoinis program interface. However, I might have make some connection wrongly somehow as it is not working. I want to try controlling the duration of the output voltage, maybe like 10 seconds. However, I must have made an error somewhere in the program as no voltage is generated 

I would appreciate if anyone can advice me on this matter.

Thank you.

Without the Nanonis subVIs it is difficult to tell what is going on.

Two of your states, No Signal Output and Reset Signal Data, output zeros. Is your program staying in one of those states?  Use a probe or put an indicator on the state wire to see what is happening.

Do you really want the default state to be one which produces a non-zero output?

One of the missing sub VIs is called "Prog Interface - OpenAppRef.vi." Should this be called repeatedly in the loop or should it be called once outside the loop?  Should the reference be closed after the loop is stopped?

Dear Lynn, 

I understand that it might be difficult to understand with looking at the Nanonis sub vi's. Sorry about that. If I upload a PDF of the block diagram, would it help at all?

Anyway, I should clarify one thing about the program. Actually, previously, I have use the similar block diagram but I have tried to generate the voltage by using a DAQ. This time, since I intend to use the Nanonis programming interface (replacing the wire lines) from the relay output to the programming interface-Open App ref instead of the NI daq. I expected that it should work but unfortunately, although the program work for the NI DAQ, it doesn't for the Nanonis programming interface. Thus, I am seeking advice on what might had happen and what I should do. I am still a new in writing Labview programs, thus I really do appreciate to get all the advice that I can get.

Thank you.
