Boolean indicator showing fileglobals

Hi!
I´m using this OI in my projectsince it has (almost) all we need:
http://www.ni.com/example/31278/en/
However, I´m having a hard time understanding how to add stuff on the interface. The only thing i need is four LED:s for four specific test step results. I was thinking about using Fileglobals and the get property vi but how do I get the seqcontext for that inside the top-level vi of the OI? If anyone could supply a specific example for that I´d be very grateful!
Thanks!

I would use a Functional Global Variable (FGV) to store a reference to the control on the frontpanel. Then in the callback VI you can call the FGV and set the control to the desired value.
Or you can explicitly pass the reference to the front panel control around and as a parameter to the callback.
This example kind of shows it but it's a little hard to follow: http://zone.ni.com/reference/en-XX/help/370052N-01/tsexamples/infotopics/handleuimessage_labview/
Hope this helps,

Odd even number and Boolean indicator

Hi all,
For example, I have these numbers from 0 to 112233. It will start counting from 0 and shown it on an output indicator. When it is even number (0,2 or 4,...) the Boolean indicator will become false, but when it is odd number (1,3 or,...) the Boolean indicator will become true.
I'd like to ask if it is possible to detect the values changing in output indicator when it start counting numbers from 0, and then the Boolean indicator will become false or true depending on even or odd number shown on an output indicator? How can I do that?
Thank you!

It may not be that much faster. In the little test VI Q&R takes 581 ms for 10^8 iterations while AND takes 503 ms. That is 78 ps difference. Hardly enough time for a coffee break. Unless you drink really fast.
Yes, both are "fast enough" for all practical purpose. Even thought they are nealy identical in speed, the Q&R shows more variability in execution time (10% variability), while the AND is singificantly more stable (>1% variability).
(Make sure you disable debugging for a 10x speedup overall)
It also seems that the AND code folds better. If we change the control to a diagram constant, the AND version speeds up by a factor of two, even though no folding is shown anywhere inside the sequence structure. I have no idea what that means.

Digital Input VI boolean indicator

I am using the Example VI Digital Input as part of Fieldpoint.
It works fine on its own.
That is, I can place a voltage across the terminals of the DI module and the respective Boolean LED lights up on the front panel.
I'd like to use the VI as a subVI for another program.
I wired the connectors of Digital Input.VI connector pane such that the Fieldpoint IO Input and Boolean indicator array have connectors.
I placed the Digital Input.VI in the block diagram of another VI and created an indicator on that VI to see the status of the array within the Digital Input.VI.
Running the higher level VI and the boolean array on it is disabled (greyed out) but the boolean array on the Digital Input.VI is working properly.
Any ideas?
I'm just looking for a way to obtain a status bit type response to be used elsewhere.
If one of the DI module channels is set high then the bit would be set (LED on) in my higher level VI.

Alright, found that if I just take out the guts (Fieldpoint IO, FP Read, Type, Boolean indicator) and use that in my VI all works well.
Now all I need to do is determine what bits are set and act on set bits.

I want to add boolean indicator

i wan to add boolean indiactor please help me frnds
Solved!
Go to Solution.

Create a boolean indicator. Put it in a single frame flat sequence structure with the List Names property node and wire a True constant to the indicator. Now when that frame of the sequence structure executes, the boolean will be set true the same time the data is going into the property node.
Of course you need to have a way to reset the boolean indicator to false at the beginning of the program. So wire a False constant into a local variable of the indicator and be sure that piece of code executes at the beginning your VI's execution.

Why do boolean indicator outputs toggle when true is written repeatedly?

Hi,
I'm using an LED boolean indicator in a sub vi connected to an output terminal.
If TRUE is repeatedly written to it then it toggles between ON and OFF as though it were a push button switch and each TRUE received was someone pushing the switch.
If I disconnect it from the output terminal then it behaves as expected, staying ON if TRUE is repeatedly received.
Why does it do this, how can I fix it?
Also, how can I turn all breakpoints off collectively without removing them?
Thanks,

Hi Dave,
go to File>>VI Porperties>>Execution and check if "Clear indiators if called" is checked.
If this is checked it clears the indicator when the VI is called. If you set the value to TRUE this value will be given back to the calling VI.
This behaviour was introduced to allow simpler programming. Think of a programm with various cases. There is only one case where you want to set the indicator to TRUE. If you haven't the above flag you need to set it to FALSE in all other cases. This forces to move the terminal outside of the case and to wire a lot of FALSE constants to the tunnel (nowadays we have the "use default if unwired" mechanism which makes the flag unnesseccary).

Remove shading of boolean indicator

I have created a boolean indicator which has some default shading to it. Is there a way to get rid of the shading (plain color, unshaded) using the property nodes. The help file doesn't really appear to address shading.

The trick is to copy the images from the Modern control to the images of a classic control.You do this using Customize Control...
See attached file.

I have had a message indicator showing I have a text for a week now and there is no text.

I've reset it multiple times and gone through my entire text history to see if I could find anything unread and I cant. How can I get this to go away?

When you say you've gone through your entire history did you click on each thread or did you just scroll through the main page of messages after clicking on the "messages" app? Although that may be tedious (you don't have to scroll throuh each thread...just click on it and then go back to the main page) it might help clear that indicator for you, What may have happened is that the indicator showed while you were exiting an already opened thread...and you saw the message prior to exiting but the indicator managed to show at the same time. If you don't want to do that then you might have to restart your iPhone to see if that helps...which it might not...OR you might need to do a restore...which you may not really want to do, but might be what you need to do to get things back right. Also, try searching the Apple Support site (apple.com/support) to see if they have any articles to address something like this and what troubleshooting techniques it recommends.

System style boolean indicator

Experts,
Does anyone have a nice tidy way of displaying a boolean indicator in a system style? A checkbox does not seem like a good idea to me as it implies the user is able to click on it and change it. I could disable and grey it but again this implies something different.
What I am after is a simple and neat method of displaying a boolean status to the user. I am using a small-ish boolean off the modern pallette at the moment, but it does not really fit in with the rest of the system scheme.
Thanks

Another option takes a bit of digging around in the control editor:
1. Create a new custom control, starting with a system listbox. Once dropped, change to Customize Mode (click the wrench/spanner in the toolbar), right click on the border of the list box and choose to copy to clipboard.
2. Create another new custom control, this time starting with a modern LED. Switch to the customize mode and right click on the border of the control and choose to paste from clipboard at the same size.
3. Repeat for false as well as true and resize parts to suit.
4. I ended up with something like this:

Animated Boolean Indicator

I would like to create boolean indictor to show the status of a motor fan.
The indicator will show a static fan if the input is false.
It will show an animation of the fan turning i.e. moving when the input is True.
Would appreciate if anyone could offer some advice me on how to carry out the implementation.
Would it be easier to implement the control using the picture control toolkit or the picture ring control?
I was unable to locate any help on picture control toolkit from the Labview Help files. The only documentation which I have was an obsolete Labview Picture Control Toolkit Reference manual dated back April 1994. It was downloaded from the NI website.
Please share with me any websites or books which you may know th
at provides more help or info on how to use the current version of the Picture Control Toolkit.
My current Labview version is Labview 6.0.2
Please feel free to email me at [email protected] if you have any advice or vi to share. Thanks.

If you want to be really fancy, then upgrade to LabVIEW 6.1 which supports gifs(or rather the generic gif standard). This includes animated images. What you would need to do is to drop a classic square button in LabVIEW 6.1. The classic buttons have none of the 3d stuff. You then right click on the buttons >> advanced >> customize. This launches the control editor. Edit the control and import the animated gif from file for one state of the boolean button and you can import a static image for the other state. Now you have a boolean that will toggel between a staic image and an animated one. It will be tough to figure it out at first but learning how to customize controls is very rewarding.
You can learn more about the editor by looking at the
shipping doc "LabVIEW Custom Controls. Indicators, and Type definitions" This is found by opening LabVIEW >> help >> search the LabVIEW bookshelf. This launches a pdf of the shipping docs. A link to "LabVIEW Custom Controls. Indicators, and Type definitions" will be found there.
I have attached an example I wrote for LabVIEW 6.1

Boolean indicator come on and stay on if only one data point outside of limits

Okay, here goes my second rookie question. My first one was solved in a matter of hours after posting here, so I am going to give it another shot. This has probably been posted elsewhere, but I just am not familiar enough with the terminology and know how to find it in this forum... sorry for that.
Currently, I have a setup where I am using an In Range and Coerce function in the Comparison Pallette to check the output of my source and compare it with a user inputted upper and lower limit. I have hooked up an LED indicator to the Index Array and then to the In Range output. Right now, if my data goes outside of the limit, the LED Indicator will light up, but it will immediately turn off if the data goes back within the limits. I want my LED indicator to come on and STAY on if even 1 data point goes outside of the limit. What can I connect between my LED Indicator and my In Range Comparison to make this happen?
Sorry for being so new to this!!

Hi Spsuengr,
I have attached a boolean toggle vi for you. You can insert this vi in between your led indicator and in range output. It will latch the output by default. You can use the latch(t) input to disable the latch feature (to perhaps reset).
Above is the boolean latch vi
Above is how you need to insert it into your code. If you leave the Latch(t) input unconnected it defaults to a latch output. Only wire a control to this if you want to either change the output so it follows the input or if you need to reset the output.
Rgs,
Lucither

Mail 'reply' indicator shows up even though msg not replied to

I just upgraded to Lion a few days ago. I am having new messages show up with the curved reply indicator, even though I have not replied to them. It seems if I have EVER replied to a particular recipient, (as in a past reply was sent), then the indicator appears, even though I have not replied to the latest message.
With the volume of business emails I get, this indicator has in the past always helped make sure that nobody is dropping through the cracks, and I get back to everyone. Now this appears to not be working. Is this a bug or what?
