Digital control system, using limits of entry of data with global variables

Hello!

I have a Subvi with several digital control sliders. These control framerate, the pixel clock and exposure of a camera and their change in max/min/increment whenever one of them is changed - they are interdependent and get their information from the camera continuously during execution.

I'm trying to remote control this VI, but during the passage of a value using global variables, it doesn't "stick".

Example:

The value for exposure is 237,48 Ms. different values are constrained to the nearest value. So if I pick 240,00 ms at the Subvi, he should know that this is not a valid value and change to Mrs. 237,48.

But it is not do and I don't know why. When I enter the values manually, it works fine.

Any suggestions?

The limits on the controls that apply when their control from the front and is not passing values via the connector pane.

You should use something like "line and force" within the VI to validate the values are within the range (maybe constrain data or return an error).

  • How to create a digital control (of any type) which can be increased or decreased by a 'unit' at the same time?

    As in the title.  I want to create a digital control (no current limitation on its type) with a range of 1 to 10 (and a step of 1).  The only difficulty that I have, is that the user should only be able to increase or decrease 1 at any time.  Code initiated by this change of value must have completed at least once before that the value can be changed again.  This is because code of VI is mainly contained in a while loop and control are read once at each iteration and its last value should not differ more than 1.

    Is this possible with LabVIEW 6.1 and if so, how?

    One of the solutions that I came up with so far is to disable the control immediately after its reading, and to turn it on again immediately seized is read the next time (I have to assume that the user is unable to click twice before the control is disabled).  It is an acceptable method, or is there a better way?

    I also had an idea of partially disable a normal digital control, such that it could not be typed in - only arrows remained operational.  However, I'm not sure how.

    Hi James,

    You can use the two buttons (by releasing latch) and a digital display that shows the current value. Button increased the value and the other decreases. Store the value in a shiftregister to work with her.

    I don't know if your solution would work because use may directly enter the new value.

    It will be useful.

  • Code 150:30 after having to recreate my SYSTEM using Apple time

    Hello

    I had to restore my entire system using Apple Time Machine, after problems with the printer and Scanner Control Panel. (I'm under El Captain version 10.11.3).) After completing the restoration I can no longer launch Photoshop CS4, Illustrator CS4 or InDesign CS4 Ser # 1327-***-***-***-***-*** [Serial key removed by Mod]. What should I do to get my license working again?  I'm just reached by an error message and the code 150:30. I am on a tight work schedule and need to access my emergency license.

    Thanks for the help!

    Best regards

    Ingvar Ericson

    The problem is that CS4 licenses is broken in species migrated or restored from Time Machine.

    There are two answers to this problem.

    Reinstall CS4 including all updates.

    Or if you don't mind using Terminal.app and run the script in recovery of the license, the problem can be solved on the spot.

    Here is the guide step by step screenshot for it. Start the 11 message and read it through carefully.

  • I don't get to use the global variable. Take a look in my form, please.

    Hello.

    I'm ashamed. I'm not able to use a base on the LiveCyle feature: Global Variable / object.

    I have a textfield for the user to put your name. Then, the user must click at the base. His name and value must be of value to a global variable, then I would use this value in any form.

    This look at my example I would use this value.

    https://Acrobat.com/#d=k0YlC1MXEdVTh1g2TXAJxw

    What is the error? I tried to put as a global variable, but it does not work.

    PS: Call of the value using textfield (TextField.rawValue = TextField2.rawValue), it works fine, but I prefer to use the variable

    Thank you very much.

    Hi Rafael,.

    I'm good thanks

    I do not know if I understood the question, but I think you're asking if it is possible to have a field that displays the value of a global variable (i.e. the 'view' you refer to), which is updated automatically via scripts of calculation or similar to but not dependent on another event, such as 'click '.

    In my view, using a linked across the object world is the only way, and you are right - it is certainly easier.

    Please let me know if I've not understood the question

  • A digital control takes no account of the limits of data at entry entry is typed, why?

    Limits of data located in the property entry seem to have no effect on data entry. A value written to a property node limit the contribution of the increment of buttons but not the data which are entered in the control. How to stop digital control to accept out of desired range values? In the attached example, why I can type in any number for control and data entry limit is ignored?

    In the Properties window of data entry for the digital control, you have the "answer of value out of range" ignore the value.  Change it to compel.

  • Need help on the use of the PCI-6221 and c# to control three digital Port and an analog of entry

    I need to send the digital output at three ports and then read an analog input voltage using the analog card PCI-6221.

    I did a c# program to fight against it. I built four tasks altogether. Three tasks for three digital output ports and a single task for analog input.

    How can I reduce the time?

    Using my method, to 3.3ms in total. And it's slow.

    I can build one task for three ports?

    What is the best way to the control task to reduce the time of communication with the PC?

    Is that possible to save a lot of analog reading entry in the memory of the DAQ hardware and then read it all together from the computer in order to reduce time consumption?

    1 million thanks!

    Hello

    Hi Jin,

    To answer your questions, Yes, you are able to configure a task of digital output to use three output ports and PCI-6221 has a buffer of memory FIFO aboard 4095 samples.

  • Can I use a digital control to change the illustrated index of an array?

    Hey people,

    This could be one of these questions, get feedback 'why would you do?', but I wonder if there is a fairly simple solution, I don't know everything...

    I know that tables are not exactly gems when it comes to claims for benefits, but with my particular application, if I could get a digital control to define what the array index appears, it would be great.  In addition, assuming that it is possible, then I think I could find a way to have two Boolean values which would increment/decrement the element indicated by updating the digital too...

    Any ideas?

  • You can use the value of a digital indicator in a digital control?

    Hello!

    I have to develop a code where I need to find the maximum value of a waveform and draw a line at 50% of the value. So I chose find the amplitude of say 10 cycles of waveforms and found the maximum value of the amplitude.

    But my real problem is, I have to use the maximum amplitude value I get from the table VI maximum and back into a program to calculate the value of 50%.

    So it is possible to use the value of a digital indicator and put it in a digital control? As in MATLAB or C, you give a name to the variable and use it later to do all the calculations. Is it possible to do something similar in LabVIEW?


  • Exec.vi "Wait until completion" system uses a lot of CPU. Help

    I am writing an application that calls parallel instances of an external program. I have the code of work to run the EXE file with the Exec.vi system. When the completion up to wait entry is set to true on Exec.vi LabVIEW system uses all my CPU. The EXE I am running is an exe of low intensity, and if I don't wait until completion LabVIEW has no high CPU usage. It would be nice, but I have the code which needs the EXE to finish before moving. I'm doing something wrong? I could not find this behavior as a known issue, so I would like a mental health to make sure I'm not stupid fouls. I have attached a demo that recreates the question. The VI called the EXE with lance Notepad and then updates the text in Notepad. I am attaching the source code of the demo EXE as well.

    Brandon.Baxter wrote:

    Thanks Bob

    LabVIEW sequentially launches 20 cases of "Idel_EXE.exe" who are getting a Notepad and returns information.

    This description is exactly what asynchronous call and collect is supposed to manage.  'Call' treats only the controls, move the VI 'in' data you call.  The "wait on asynchronous Call" does the rest - if the called VI has done and wants to pass 'out' data, this function provides the values.  As I have indicated, if the called VI is still ongoing, wait for asynchronous can expire, return an error (which you can use as a signal 'Wait a little bit longer').

    In fact, if you set the lower and upper limits for your control and use the text tool to change the labels in your control, it will be automatically changed to go in reverse, I enclose a picture to explain this more graphically.

    Why do you think that someone is watching your computer use? One would have to have
    loaded tracking software (trojan) on your computer or have access to the source of the network
