    Traditional DAQ channel Help

    If I get it right, you are reading a True/False value from your board. If you write this value to the Switch you used before, you can keep the same code you had. Change the switch to indicator and wire the output of your measurement to it. This should do the job, in case you are reading One...

    Creating a dynamic array of 1-D arrays

    What I want is not a 2-D array, what I really need is an 1-D array of 1-D arrays. What's the difference. The one I need may store 1-D arrays of different lengths. In other words, for trying to make this clear: I need a variable that may store a dynamic number of 1-D arrays of different size...

    Trouble with Multiple Instances of DAQ Assistant

    What kind of inputs are you trying to read? Are they both analog or digital? If both inputs are of the same type, you can inside one DAQ Assistant, configure it to read multiple channels. So you have to separate the signals using that Demux (don't remember it's name exactly [Unmerge Signals or...

    Opening Internal Dialogs

    I have found a way to open the configuration dialog for the Scaling and Mapping Express VI. There is a VI stored in : <LabView Path>\vi.lib\express\express arith-compare\ScaleandMapConfig.vi I have added it to my block diagram using "Select a VI..." in "All Funcs". The problem is that it needs...

    Reading and Writing Files

    The End of File error occurs after I take the first read, what means the Express VI is not restarting from Begin of File (BOF) on the next read but from the position it left the file on the first time. How do I do to "Reset" the Read LVM File Express VI to start reading from BOF every time it...

    Controling Program Flow

    You didn't get it right. The stop button stops a loop that exists inside the event, not the program loop. But don't worry I have already solved this issue by digging a little deeper in the LabView help. The problem was that I had more than one event structure inside the program loop. The...

    SubVIs from scratch

    Thanks for your help. I knew there had to be an easy and practical way to do this.

    Showing and closing Front Panels

    Thanks for your help. This SubVI I'm doing is supposed to be a configuration dialog, so I solved the problem by creating one event structures for the two buttons (OK and Cancel). In the OK button event I do the processing, in the Cancel event I don't do anything, and as it is only one event...

    Controling Program Flow

    I have a front panel with 5 buttons and one combobox and some graph indicators. In the block diagram I have the Event structures for 4 of the buttons and the combobox. The 5th button (let's call him the Stop Button) is a while loop stop control inside one of the events (let's call this event of...

    How do I make a button in the Front Panel open the Properties dialog of a Scaling & Mapping Express VI? Is this possible? If so, how exactly?

    Reading and Writing Files

    Another one: (LabView 7.1) I'm trying to write a file containing 3 lines with 3 numeric data. I've tried using the Express Write LVM File, and it creates the file allright (without headers and with time column). But when I try to read from it, it returns an error saying that The File has...

    Showing and closing Front Panels

    Another LabView 7.1 question: I want to know how to show and close the Front Panel of a SubVI. I've found in examples and help that in order to show the Front Panel of a SubVI I have to configure "SubVI Node Setup". I've configured it to "Show when called" and "Close afterwards if originally...

    SubVIs from scratch

    Hi, I'm new to LabView (5 days now), and I have some questions to clear out that I couldan't find in examples and neither in the help. I would like to know how do I add Inputs and Outputs to a SubVI I'm creating from a blank template? I know that if I create from a selection in another VI it...
