  1. I mean other dots like the coercion dot that can appear when we connect an input to a VI. Sorry, I'm not sure if I am clear because of my poor level in English!
  2. Thanks JFM. And do you know about other dots?
  3. Hi all, I have a question concerning the inputs in Labview. Yesterday, I wanted to change an input format from a decimal representation to an hexadecimal one. Then a grey triangle appears on the input of the VI used (see attached file below) I have seen on this forum that it has a meaning but I can't find where anymore! :headbang: Can someone help me ?? Thanks in advance!! CocoWK
  4. thanks a lot for this help... I'm not sure to have understood all, but I'll come back here if it's necessary
  5. Hi everybody! I need to open another VI from my main application (in order to group settings and other parameters).. To describe my application: I want a main window composed with my main VI interface. Before the user launches the tests (because my application consists in multiple tests), I want to open another window, which is another VI that contains all the parameters for the tests. When the user closes it, I want to get all the settings to import them into my main VI. Is it possible? Can someone help me? Thanks in advance Coco
  6. Yes I know that it is better to link directly to the terminal, but it's not possible in my case. That's why I asked the question :laugh: Thanks for all your advices. I didn't have the idea of testing this way... coco
  7. Hi! I am beginner with LV. I want to know the difference between a "Value" Property Node of an indicator (integer, double or other) and a local variable pointing on this same indicator. Is there a difference in terms of performance?? Is there one solution to prefer??
  8. Thank you for your answer. It's not exactly what I wanted to do. I want the measurements to be done continuously that's why I put a while loop and not a for loop. But perhaps is it impossible. Your answer helped me, and I will work on it to try to get what I want. Thank you.
  9. Hi everybody, Sorry for my poor English, I'm a french student in internship using Labview for the first time. I want to simulate a random binary frame. I found functions in Labview that can generate sine waveforms and square waveforms but using a periode. In my case, I want this signal to be square and to represent for example a binary sequence measured on a bus line such as CAN bus. Is there a vi in Labview that realise this? Or do we have to generate this signal ourselves? Then, here is my problem: I made a vi that generate this type of signal, and I wanted to measure the signal pulse
  10. Thank you for your advice. My VI runs correctly now. Thanks See you Coco
  11. Ok thanks.. I thought it was possible because of my sequence structure.. So, if I understand, if I put a stacked sequence diagram, and place a event struture in the first part of the sequence, this event struture will be active for all the sequences of the sequence diagram?
  12. ok thanks.. here are the main vi and its sub vis.
  13. Hi everybody, Sorry for my poor English, I'm a french student in internship. I don't master Labview. I have a problem using the "Two Button Dialog". I need to design an application to verify hardware specifications. What I want to do, is to prevent the user from stopping the VI before the end of the process: I want him to confirm that he wants to stop the VI. So for example, I have two buttons: the first one is used to Close Labview, the second is used to Stop the VI. I have added two Button Dialog with different messages to manage the differents cases. When I execute the VI, the messages
