How can I unlock a front panel/block diagram in LabVIEW 7.1?

I inherited LabVIEW (7.1) code  that when I try to edit, I am not allowed. I can access and used Functions and Controls, but I cannot connect or delete them back. The mouse indicator is a hand all the time. It does not change to cross hair or wiring tool.
In the  Security section of VI properties "Unlocked(no password)" is selected.
How  can I fix the problem?
Thanks for your help. 

Sounds like you have got the automatic tool shutoff, go to menu and select window/ tools pallette and then turn back on the automatic tool. I think this is where it is located for 7.1.

  • How can i access remote front panel in RT with LabVIEW run time engine in client PC

    Hi to all,
    I have developed the RT application with cRIO 9075 integrated chassis. And i have access its remote front panel in client PC. Now i want to access the remote panel in the client PC without having LabVIEW runtime engine. If i connect the remote panel with that client, it shows only the vi border. i doesn't downloads the  front panel.
    How Can i access its remote front panel without LabVIEW runtime engine in the client PC?

    You cannot view a remote front panel without the LabVIEW runtime - the LabVIEW runtime is what makes the remote front panel possible.  What you will want to do instead is likely create a Web Service that you can access from a remote PC without requiring the LabVIEW runtime.  However, this will require you to develop a web-based HTML or similar UI to interact with the VIs running on your system - NI hasn't yet created a way to export a LabVIEW front panel as an HTML'ish page.

  • How can I display the front panel of the dinamically loaded VI on the cliente computer, the VI dinamically loaded contains files, I want to see the files that the server machine has, in the client machine

    I can successfully view and control a VI remotly. However, the remote VI dinamically loads another VI, this VI loaded dinamically is a VI that allows open others VIs, I want to see the files that contains the server machine, in the client machine, but the front panel of the dinamic VI appears only on the server and not on the client, How can I display the fron panel with the files of the server machine of the dinamically loaded VI on the client computer?

    I down loaded your files but could use some instructions on what needs run.
    It seems that you are so close yet so far. You need to get the data on the server machine over to the client. I generally do this by doing a call by reference (on the client machine) of a VI that is served by the server. THe VI that executes on the server should pass the data you want to diplay via one of its output terminals. You can simply wire from this terminal (back on the client again) to an indicator of your choosing.
    Now theorectically, I do not think that there is anything that prevents use from getting the control refnum of the actual indicator (on the server) of the indicator that has the data, and read its "Value" using a property node. I have never tried this idea but it seems t
    hat all of the parts are there. You will need to know the name of the VI that holds the data as well as the indicator's name. You will also have to serve all VI's. This is not a good idea.

  • How can I create multiple front panels for a single block diagram?

    Hello,
       I have developed a VI with multiple controls and indicators that needs to run on computers with screen resolutions ranging from 800x600 to 1680x1050. The problem I'm having is that the front panel does not properly scale for this range of resolutions by checking the options in the "VI properties" option. Is there a way to create multiple front panels of various sizes for my block diagram and programmatically select the appropriate front panel based on the screen resolution?
    Solved!

    See the attached Zip file.
    I have two different front panels.  Open either one and run it.  They both call MainCode.vi which takes the references passed to it and register for events.  From there, it does all the work of the code you would have put in your front panel .vi.
    This way each front panel can be laid out however you want for each screen resolution.

  • How can I use multiple front panel controls to be mirrors of each other?

    Hi All:
        I know this is going to be a strange question, but I have multiple inputs that control one output.  This in itself not necessarily difficult, but I have a strange need.  If one of the control inputs change I would like this to be indicated by the other controls.  For example, I have a slider, numeric and dial controls on the front panel that control RPM.  If the slider changes to 1000 RPM I would like the numeric and dial controls to see that change.  Is this possible.  If so, can you give me advice on doing this.  I am using 7.1.  Thanks for the help.
    John Honnold

    What you want is not that hard, but asked for a rather  limited times.
    Here's a how to:
    Drop a slider
    Right click Visible items-> Digital display
    Right click on the slider Advanced-> Customize
    Right click on the Digital display Replace select the control you want to replace it with (a gauge for instance)
    Right click on the Gauge Visible items -> Digital Display
    Now you have one control with three control options:
    This was done in 8.2 but I think the same goes for 7.1

  • How can I enable my front panel audio??

    the type of my mainboard is MS-6552,when I inserted my earphone and microphone into the jack of the box,I can hear nothing! then I opened the box,I found that the wire was not the proper place,there were 8 wires whick marked with “MIC IN,GND,LIN,LOUT,MIC IN,GND,RIN,ROUT”,I also found the F_AUDIO on the mainboard,there were 18 pin on it,I cannot matching them! who can help me?thanx

    Look through you mobo's manual and you'll find it... Don't get stressed out too early... The first computer I built myself got me stuck in the same area for hours!!!
    Btw, you've got to remove the jumpers on your mobo to enable front panel sound. Be warned that most mobo only allows you to us either front panel or back panel sound only. Please also ensure that there are no stand offs underneath your mobo.
    All the Best... :D!!!

  • How can I arrange the front panel?

    Hello,
    I’m using LV 7.1 and created a VI with many controls and indicators. It writes and reads data to and from a bus system. For that I used the flat sequence structure and many case structures.
    Now I would like to order the front panel, i.e. by using the tab control only the data read or only the user settings should be displayed.
    But using the tab control slows the whole VI down, so that a data recording in real time is impossible.
    Are there any other possibilities to bring the front panel into order if the number of controls and indicators is too high for the screen?
    Thanks in advance,
    UoS

    Do you mean that the CPU usage goes up and the PC responds slowly. If so, this is interesting. This is most likely related to a grphical element causing the system to slow down. The tab control should theoretically take care of this, but about a year ago I ran into a similar situation where a tab caused problem here. In that case it looked like controls that were partially displayed caused the problem and when using the tab control the problem was there even when displaying another page. If this is so, you can try to determine the source by scrolling the screen in different directions. Once the problematic area is moved off the screen the VI should run faster. This way you can tell which area has the problem.

  • Urgent Help! How can i execute in the same block diagram two separate labview codes each one with diferent execution timings?

    Dear All.
    I have 2 application progrlams in the same block diagram. the intention is to use  the 2 programs at different excuting time for different application, and each have stop and start button ofcourse i will have master stop. But when i run the program, it only works one program at time , that is the 1st block which i make it active only , when i tried to make active the second block it will not work, only works when i stoped the1st one. So, this it to request ur hlep how can i solve my problem. here i have attached some of  my program.

    Usually you set up a task that has all the channels from all the modules configured. When a loop starts it reserves that task and the cDAQ can't be used by other loops unless you start and stop tasks.
    You can have one loop acquire all the data and if you want certain channels to go to other loops you can use the producer/consumer design pattern. If you wanted a third loop you would add another queue and the third loop would dequeue that data. See attached.

  • Front panel / Block diagram sometimes disappear

    Hi, I am running LV7 on Windows XP. When I have a few windows open
    with front panel and corresponding diagrams, some of those windows
    disappear after being minimized or put in the background. When I try
    to restore the window,Ctrl-E or task bar, only the function- and tool
    palettes get focus.
    This is very annoying! please help

  • How can put on the front Panel the Bolean controll to activate stack plot2 mode?

    In the properties of Waveform Chart there is the possibility to show all charts in one monitor or the Stack Mode Plot. Can I put a bolean Controll to use this stack plot in run time by Control Panel?

    You can't change between stacked or overlay mode at runtime. You could use two different charts and make one or the other visible/invisible.

  • How can i execute in the same block diagram two separate labview codes each one with diferent execution timings?

    Hello guys. I have been trying to solve this by a long time now...but i cant solve it....
    I have my main code in labview beying executed in one timed loop of 1second.....but now i need to pulse a lazer very fast than one second...
    my ideia was like executing the lazer pulse code in paralel with the main code but with a mutch faster timed loop....but when i put the second timed loop outside of the main one....it hapens that the aplication keeps runing only the faster loop and the main loop doesnt run....
    I really dont know how to solve this....
    many thanks

    JOSE,
    your code is really difficult to read. Please do some cleanup work, your diagram should be only little larger than an average computer screen. What I have glanced so far is that your code has a lot of beginner mistakes (overuse of local variables).
    For multi-loop applications, you shoul have a look at the tutorials concerning Producer-Consumer design pattern. The quick and dirty approach is to use locals (a bit contradictonary to suggest using locals here after I stated an overuse of them). The drawback will be, that you lose the latch mechanism of the button and must code it on your own (and make a big set of mistakes, using locals always attracts race conditions). Most important is that you write to your button only once, after all loops have finished spinning.

    Call AT&T and see if you qualify for an unlock. If you do not, maybe you can get your friend to contact them and request an unlock, if he was a customer. Only the carrier the device is locked to can authorize an unlock.

  • Can I Bind a Front Panel LED to a specific element in an array of booleans?

    In LabVIEW 2010 I have a string of LEDs. I have and array of boolean values that contain the values that the LEDs should indicate.
    What is the best way to connect the LEDs to elements in the array of booleans?
    Can I Bind a Front Panel LED to a specific element in an array of booleans?
    How is this done?
    Can anyone show sample code?
    Solved!
    Go to Solution.

    Imagine that you have an I/O card that provides 128, 256 or 1024 digital inputs and the requirement is to have an LED on the front panel to represent the state of each digital input. This frequently occurs.
    Wiring that many digital inputs individually is a royal pain and then some !
    It would make sense to have one shared variable as an array of Booleans that represents the status of all inputs and then use data binding instead of wiring each individually. The individually wiring would violate all recommendations on diagram size and fan out.
    Frequently scanned For loops to update all of the LEDS would take alot of CPU time.
    Wouldn't it be MUCH better if PSP could be used to update the LEDs whenever the data changed (as it is supposed to do) ?
    In my case I have a LabVIEW Yaskawa servo driver that provides me information about 16 servo drives that may be connected. I have LEDs on the front panel to represent some of that status for each individual drive. But Yaskawa provides the information on the drives as an array of clusters of information for each drive, which I perform some business logic on and turn into shared array of Booleans to feed the LEDs (and some banks of switches as well).
    Unfortunately LabVIEW does not seem to have any way to bind the LEDs (and Switches) to individual elements in the shared array of Booleans. It is just not that smart. Even with only several banks of 16 LEDs and Switches, wiring them individually using Decimate Array of Index Array functions is a royal pain and makes the block diagrams very large. It would be much worse and almost unreasonable to do if the size of the information was much larger.
