Disable block in Vivado block diagram design

I have several blocks in my design which I would like to disable (not delete) from the design so that my build time is faster. Is there an easy way to do this from the GUI or by editing the hdl that doesn't break the block diagram view? Thanks

Hi ,
Use the following TCL command:
set_property is_enabled false [get_files <project_path>/bd/design_2/design_2.bd]
In Vivado GUI. Select the block in File hierarchy and right click to Select Disable file as shown below:

Why Is the Block Diagram Disabled?

What did I do now? Please look at the attached image. A VI that I am using as a subVI in various different programs suddenly started looking like I had used application builder to create an exe file out of it (But I didn't!!). The only options are Start and Run Continuously, and the block diagram is disabled. What did I do to get myself in this mess? How do I undo whatever I did, so I can edit the block diagram again? Any help or suggestions would be greatly appreciated.
Thanks!

Did you ever built a source distribution with the option set to remove the diagrams? In this case, the original must still be around somewhere.
Since LabVIEW 8 you can no longer simply save without block diagram and you would not be able to upgrade such a VI to LabVIEW 2011, which it is now. (details)
Of course it is possible that there is some corruption, but looking at the memory usage, the block diagram is blanked out.

Disable (all) functions on the block diagram with right-click menu

Hello to everyone,
here is one more idea, which I'd like to propose.
As for me, it would be useful to have the following: when all components (functions, wires, subVIs, etc.) are selected on the block diagram (like, after ctrl+A), operator could do right-click, and in the menu would appear menu item "Disable everything". After it, all the code could be placed into Disable structure.
Of course, I can add Disable structure to block diagram manually, and cover whatever I want, but with right-click menu it would be much faster.
Also, it can be modified to disable only selected items - then each of them can be placed into separate Disable structure, and, for example, additionaly in the enabled case of Disable structure, corresponding wires will be connected. Sometimes it is needed for testing - just to disable couple functions, and test subVI. Or to disable subVI fully (it's faster, then disable place, where it is called. Especially, if subVI is used in many places).
It will not make debugging difficult, because anyway Disabled structures are used; such functionallity can just make life a little bit easier...

There is always the File->New... which opens up a new window. You can have your templates in that window by putting them somewhere (I don't remember where at the moment).

Block diagram errors even when block disabled

Should LabVIEW give the broken arrow for errors within a disabled block?
I have a block disabled where way down in the call tree from a VI within that block there is a broken VI.
Nothing else calls this broken VI except the VI from the disabled block.
Why should I get the broken arrow if the top level caller is disabled?
TestStand 4.2.1, LabVIEW 2009, LabWindows/CVI 2009

Thanks for the thoughts guys.
I have discovered that the errors in the disabled section appear in the error list box when there are other 'real' errors.
When there are no other errors, then the errors in the disabled section do not affect the run arrow.
Typically commented or disabled code is ignored by a compiler - and so I think it should be the case with LabVIEW too.

Can we design analog to digital signal conversion block diagram (ADC) in labview

hi every one,i've doubt i.e can we convert function generator output (i.e analog signals) to digital signal in labview......can anyone help me how to create ADC circuit that means ADC Block Diagram in LABVIEW.....please give me solutions for my problem

Hi guru,
from signal generation VIs you get arrays containing float values (aka DBL). Those floats are just digital values made of 0s and 1s…
Any value in your computer is digital!
To provide a solution you need to rephrase your question! What exactly do you expect as result of your operation?
Edit: kkkkkkk ur ckt ???

Hot to disabled the "Block Diagram to show" for other users?

Hi,
I am doing a LabVIEW program that other persons may use.
I need them NOT to be able to access the "LabVIEW Block Diagram" (by doing e.g: Ctrl + E).
How can I do this?
Kind regards,
Amaloa S.

Hi Amaloa,
You could achieve this by:
- Click File (on your front panel) > VI Properties
- On the Category drop down list, click Protection
- Select Password-Protected
- Enter New Password and varify it again

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.

LabView application hangs up when scrolling the block diagram

Hi all.
I attached you "Main.vi" that is part of my LabView project. I don't know what's going on, but when I scroll the block diagram to the maximum right, the LabView application hangs up. There are a lot of things in this block diagram because is an outline yet. My plan was to make it more structural, but now I can't do anything because this error don't allow me to edit the diagram.
Please, try to open it (ignore all the dependencies) and check if it hangs up also in your computer.
If it does, is there any way to recover it? It's really important for me because I don't have any backups since two weeks ago...

Francisc

It didn't hang up on my computer, but it did make me nauseous, luckily I keep a bucket by my desk.
You might have video card issues. Try this: open the VI, and hit Auto Cleanup, then save. Close LabVIEW, reopen. If that does not work, try to get to the far right side by going to the Front Panel, and double clicking something that will take you there. If you get there successfully, use the disable structure to disable ~ 1/8 or more of the diagram on that side. Save, reopen.

Property Node activated even though it's been removed from Block Diagram

Hi,
I messed around with the property node of one of my controls and when I was finished and removed the property node from the block diagram it still makes my control blink.
How do I make it stop??
Is the option of Enable state not possible to set in property node mode. I'd like to go from disabled and grayed to enabled.
Thanks.
Solved!
Go to Solution.

Hi
Your blinking property might still be set. Add the property again to set it to False.
To set the enabled/disabled/grayed state use the "Disabled" property.
Hope this helps.

Nugget: Open block diagram programatically

There are a way to open a block diagram programatically. Exists a undocumented function located in
"%Program Files%\National Instruments\LabVIEW 8.6\vi.lib\Utility\sysinfo.llb\Set Block Diagram Open.vi"

My good old 7.1. (ok, I run that in hyper-boost mode ) has a property node 'VI.Block Diagram Window.Open'. Should be available for anyone and documented in 2010.

Is Block Diagram Open

Is there a way to tell if the Block Diagram is open when a VI is started? I have a subVI that is set to modal when open. When trouble-shooting, if I run my application, but forget to disable modal for the subVI it causes the system to lock up.
It would be nice if I could set the property of the VI to not be modal if the block diagram was open.
Any suggestions?
Solved!
Go to Solution.

I would attempt this by doing several things:
1) Go to the VI Properties>Window Appearance and click on the Customize button. From there uncheck the "show front panel when called" box.
2) When the VI starts, read the VI Property "Front Panel Window.State" - this will tell you if the window is already openned (ie if the window is openned the window state will be "standard", "Maximized" or "Minimized"). Note: this is the visibility of the front panel, not the block diagram
3a) If the VI is not already opened, set the "Front Panel Window.Behaviour" property to modal and then open the front panel using the VI Invoke Node of "Front Panel.Open". This is basically mimicking the behaviour you describe right now.
3b) If the VI is already opened, set the behaviour property to default or Floating to allow you to click other windows.
4) When finished, if the VI was not already openned, manually close it using the Front Panel.Close invoke node (if it was already openned, leave it openned)
I've attached a screen shot of this kind of thing. I hope this helps,
Shaun

Navigating a complex block diagram

Hello Guys,
I already have an existing VI which is very complex with several tabs. The block diagram is pretty huge and i am having difficulties in finding SUB VIs in the block diagram. Clicking on any of the tables in the front panel doesnt take me to block diagram. Does any one ahs any suggestion as of how to traverse through a design.
Thanks,
Assad.

Why should it??
However, you can always right-click on any FP object and select "find terminal", "find local variables", "find property nodes", etc. All these will take you to the right place on the BD.

My scrollbars disappear when resizing my LabView8.6 Block Diagram window

My design can't be seen in it's entirety within the Block Diagram window so I need to use the vertical and horizontal scrollbars to navigate the design. The scrollbars disappear if I resize the Block Diagram window past "some point". If I shrink the window very small, the scrollbars reappear. Other programs I've generated don't seem to have this problem. Any suggestions?

Hi,
Check the scrollbars settings, right click on vertical/horizontal scrollbars and change the settings. If the problem still exists, U can send me ur vi, let me have a look to know the exact problem.

How to remove the simulation loop from the block diagram

hi,
i have used lap view version 8.6 to design pid system. i have the pid block diagram with daq on simulation loop. now my supervisor want me to remove the simulation loop. anyone know how to remove the simulation loop without deleting the pid block diagram. i have attached my pid program.

You cannot remove the simulation loop alone because all the functions kept inside that loop will work inside that loop only. If you have to remove means then you have to find another way to inplement the PID control.
The best solution is the one you find it by yourself

Cut and paste from one block diagram to another?

Is it possible to cut objects from the block diagram of one vi and paste them into the block diagram of another vi?
Also, is it possible to "comment out" parts of a block diagram like you can in a text based program? That is, can you disable "code" on a block diagram without removing it from the diagram entirely?

CVI is much easier to me than LabVIEW, maybe since I've been programming extensively in C for 20 years. But boss says we gotta use LabVIEW. It's the politically correct thing to do.
Lots of LabVIEW advocates in management here. Few have done anything of significance with it. Some use Signal Express and call it LabVIEW. I guess they're technically correct. SE says LabVIEW on the splash page.
