The PWR MGMT LED on the front panel of the sup720 is off. What happen with this?

The PWR MGMT LED on the front panel of the standby sup720 is off (But the active engine is on). We check the switch guide which states "The SYSTEM and PWR MGMT LEDs on a redundant supervisor engine or RSP are synchronized to the active module.". What happen with this? Thanks!

HI @bingxiong.feng,
This is not a cause for concern as Cisco says in the following link:

  • I am running OSX Lion 10.7.4 and the computer no longer will go into sleep mode when I close the cover What happened with this option?

    I am running OSX Lion 10.78.4 and the computer will no longer go into sleep mode when I close the cover. In system preferences I can no longer find the option that allows for this energy saving feature. What happened to this option and why is this no longer happening with the latest version of Lion?

    No external monitors or devices attached. When you mention that this function only works when devices are attached that is true when you set up your preferences that way. Up until my upgrade to Lion the computer would always go into sleep mode when I closed the lid. There also used to be an option to check in system preferences that allowed you to choose this option. My question for the discussion is what happened to that option and how do you get the computer to sleep or at least the display to sleep when you close the lid as we have been able to do in the past. Thanks.

  • There used to be an option on the home screen of the store that let you look at lists of songs made by users - what happened to this feature??

    On the home screen of the itunes store on the right hand side - there used to be an option that let you choose songlists - lists of certain songs made by itunes users - for example workout songs, love songs, date night songs, songs to run by .... 

    I believe this was part of the iTunes "Ping" feature, which has been removed since iTunes 11.

  • 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 display a changing variable in a subvi on the front panel of the main vi as the subvi is excuting

    In the document attached the vi on the right is sub to the vi on the left. On the subvi on the right the variable "Field Reading" is continuously updated on the front panel of the subvi as the "for" loop is executed, but only the last value of the variable is updated on the main vi front panel which is what is expected. My question is how can I display the changing value of "Field Reading" on the main vi front panel as the "for" loop in the subvi is running?
    Thank you.

    Hopefully I can explain it well enough. It really is simple.
    1) Create an empty global variable and call it something like User Interface References.vi
    2) For each and every control and indicator on your front panel, right-click and select Create/Reference
    3) Place these references wherever you like (I use a series of Event cases to perform my initialisation and these all live in one of these event cases). They can be placed anywhere in the main vi.
    4) For each of the references, right-click and select Create/Indicator
    5) Moving to the front panel, Cut all the indicators and Paste them in the global variable (eg. User Interface References.vi)
    6) Moving back to the block diagram, wire the global variable to each of the references and select the same named global variable.
    All the hard work is now done (until you add another user interface terminal). You should now have something that look as shown below, [except the reference labels would be to the left (not sure why the snippet put them above)]. In my latest program I have 82 references!
    Done. You can now access all your front panel controls and indicators anywhere in your program as shown below.
    You can just select Value in most cases, but in this particular case I wanted to fire off an Event to do some things (log the alarm) as well as just update the value. So, this is another bonus with the method.
    Hopefully this all makes sense. If not, let me know.

  • Using more than one front panel at the same time

    I have a main program where I can call sub vi’s and then the sub vi’s front panel opens.
    I want to use/see/operate more than one front panel at the same time. How I can do it?
    For example when I close the main program it won’t close before I close all the sub vi’s front panels.
    I use event case to call these sub vi’s. Can I close all vi's using one button?

    I wouldn't use subVIs for display, at least not if you plan to have them open all the time. Instead, I would suggest that you have one loop with a FP VI which will talk to the FP all the time and will pass to the data to the other loops through a variable or a functional global.
    Then, you can use a tab control to organize your display. If there is no specific reason for not having the graphs in the same VI, you can use a tab control to organize it. If you can't, you can also use subpanels to display the VIs and put several subpanels in your VI.
    If you still want to display the VIs seperately, you can control their positions and sizes through their proerty nodes, but I don't think there's any reason for this.
    To learn more, I suggest you read the LabVIEW style guide. I think it has some tips about application design.

  • Is there a way the user to change the equation in the formular node from the front panel on the fly, dynamically?

    Is there a way the user to change the equation in the formular node from the front panel on the fly, dynamically?

    Try the Parser VIs (also known as LV Mathematics VIs, or simply GMath VIs) located under the Analyze>>Mathematics palette (not in the Base package). You might want to start with the "Eval Formual Node.vi" located in the Analyze>>Mathematics>>Formula palette. There are many differences between these G-based, dynamic formula VIs and the LabVIEW formula node, but these VIs often prove quite useful when your formula changes on the fly. For more detail on the differences, see the LabVIEW Help file (Cntrl-Shift-? from within LabVIEW) under the topic "Mathematics VIs, parser differences with Formula Node".

  • Is there a way the user can change the equation in the formular node from the front panel on the fly, dynamically?

    Is there a way the user can change the equation in the formular node from the front panel on the fly, dynamically?

    Sorry, I don't think so. That would be pretty cool if you could create a property node for a formula node and then enter a formula on the front panel and use it to update the formula. But you can't create a property node for a formula node and the only way of modifying the formula is by typing it into the formula node on the diagram. And you can't modify a diagram of a running VI.
    You could create a VI which is only a formula node with the maximum number of inputs and outputs you expect. Have a button on the calling VI to Edit Formula. When the button is pressed, use a VI server to display the front panel on the formula VI, display a dialog box telling the user how to display the diagram of the formula VI, then stop the calling VI. (You can't edit a sub-VI while t
    he calling VI is running). The user will then need to rerun the calling VI to use the new formula.
    You might be able to do something by calling MatLab or something like that to get an interactive formula window.

  • Lock front panel until the event case for this event completes

    A Dynamic Event is a filtered event? Is this why "Lock front panel until the event case for this event completes" is not shown on Edit Event window dialog? I use Dynamic Event so I can subvi the event structure.
    I need stop my app from locking the FP whenever the user double clicks on the numerical array value (<-- the FP freezes the mouse and renders it useless) and stops the value from ever being changed. This event is registered for Value Change (not mouse up or down) and I get a locked mouse. As yet in the UI, no value changed occurs but I get a locked mouse. A LV bug?
    Trying to KISS, I can see this fixing this by moving ONLY the value change event to the top level VI instead of a dynamic registered event in a subVI. This will give me the option to NOT "Lock front panel until the event case for this event completes" .

    Thx, Ben that fixed the problem when I unchecked "Lock panel...".
    So it appears LV locks the panel during runtime once the Dynamic Reg Events is on BD and it doesn't matter if your case to handle the Reg Events is created or NOT... interesting. That's why my mouse persisted to "freeze up" although I deleted the case for my FP array.
    Its situation like what you described that has given me many insights into how LV actually works. In one of my bbuggy VI's I found that a class wire can run a million miles through multiple sub-VI queues etc but the data itself is only touched when it has to be touched. in my case it was a crash while trying to write bogus class dat to a TDMS file.
    I am glad you are back on course.

  • I am trying to create an executable vi that will call out another vi and show its front panel in the executable​. When I try this I recieve this error message "top level vi (my main vi) was stopped at unknown on the block diagram of (my sub vi)

    Well the most common way is to enclude the vi's in the build spec either directly in the dependancies that the App builder automatically generates OR by declaring them in the build spec as "additional enclusions" (like you must do for dynamic vi calls in your app.
    I have heard rummors about My.app Stuff.vi in a nugget Intaris posted- and I've wanted to dig deaper into Intaris' claims- but have not tried it myself.
    If you go down the stuff.vi route Keep us curious guys posted

  • How to active more than one front panel in the same application ?

    Hello,
    I want to active several front panels in the same application. I am a recent labview's user and it's difficult to solve this question.
    Thanks for your help.
    Regards

    But, each VI, including each subVI has a front panel. If you want several front panels, that implies using several VIs. The top level VI will call the appropriate subVI. Each subVI that you need as a UI can be set to 'Show front panel when called' and 'close afterwards if originally closed'. These settings can be accessed through popping up on the VI's icon and selecting VI Properties..., then selecting Window Appearance, then selecting the customize button or the dialog radio button.
    Hope that this helps,

  • How do I monitor parameters from a SubVI on the front panel of the main VI?

    Good day.  I have a LabView program that I am modifiying (actually it is a National Instruments demo program called Simple PID Demo).  On the Front Panel of the main VI, I need to monitor several parameters that are on a SubVI.  How do I do this?
    Thank you very much for your time and help.
    Michael

    Hi Michael,
    Global Variables should solve your problem.
    Looks like you have to pass values  from  Sub VI that will execute continously inside a main vi.
    Look at attached VI
    Hope you can implement this type of logic in your program.
    regards
