Check out this website.

Peter Bloom of bloomy controls has a file template that is a very good starting point for project organization. I think he also talks about this in the LabVIEW style guide.

That is a good starting point indeed !

We use a similar project template folder and I think this is also what NI recommends .

By the way, is anyone day-to-day using the Bird's Eye View ?

Hi,

I am looking for the best solution to first read continuousely multiple channels/multiple samples/waveforms all 1 seconds and build afterwards longer waveforms (for example 300 sec) - and the same again and again (as the program is doing unattended monitoring work).

In my opinion this is a very simple task, but the solution is not as trivial. I tried different ways, but these all seem to be a little bit complicated, therefore I ask for some good (and proven) ideas.

Thanks for your help

There was an interesting NI webcast recently, it was called : Tips for Maximizing DAQ Throughput and Performance it was giving good advice on how to set up a task that has to run continuously.

There are also many tutorial and webcasts about DAQmx.

Hope this helps

I have just started to learn to use Labview. I have a program that creates 4 separate white noise waveforms. I need to convert this to 1 waveform then back into 5 waveforms. I can only use arrays and for loops.

See attachments.

Thanks,

Hi all,

Has anyone tried to upgrade the LabVIEW version of a big project from 8.5 to 8.6 ?

I have a 1000-VIs-project (including some IMAQ / DAQmx / Motion) which originally started in LV 7.1 and as time and versions went by it was gradually upgraded in LV8, LV8.20 and LV8.5.1. The Upgrade of the LabVIEW went quite smoothly and almost as smoothly for the IMAQ / DAQmx upgrades.

But now that we try to upgrade in LV 8.6, we always end-up in a wall.

We first tried to copy the whole source folder in LV8.5.1 on a local drive, opened LV 8.6 and mass compile the folder -> LV 8.6 crash.

Then we just tried to directly open the *.lvproj with LV 8.6 -> LV 8.6 crash...

:headbang:

Anyone can share experience about this ?

The little preview you get of a window when hovering over the task bar helps, and if I'm not mistaken, alt+tab shows you a miniaturized rendering of the window too if you keep the alt held down in Vista?

The "advanced alt+tab" I was refering to does this in XP, not perfect but a lot better than the default alt+tab.

QUOTE (MJE @ Sep 17 2008, 02:48 PM)

That is a great idea, did you fill a feature request for this ? different favicon in the windows taskbar for diagram / panel / control would be cool !

I did a quick search and didn't see this before so my apologies if this is a duplicate, but I'd really like it if LabVIEW had the option to have tabbed VIs. I try not to keep too many VIs open at once, but sometimes it happens and it's a pain to Alt+Tab trying to get to the VI you want and don't even get me started about trying to Alt+Tab to another application. Now, I realize that not all FPs and BDs are the same size but I'm picuring something like Excel where all the VIs could be contained in one master window for FPs and one master window for BDs. You could Ctrl+Tab between the different VIs and then you could Alt+Tab between different applications. Or maybe something like PowerPoint where you can preview the FP/BD on the side and when you click on the preview, it'd bring up the FP/BD in the main display area to work on. Again, I think this would be best as an option so that those that work with lower screen resolutions wouldn't be hindered by this feature.

What do you guys think?

Hello,

I think that it's indeed not easy to find the VI you want when you have many BPs/FPs opened and also if you want to switch to another application using alt+tab. that said, I don't think LabVIEW is to blame for this, it's more the OS. Same for alt+tab and ctrl+tab.

Having all the BDs/FPs in a windows (like in Excel) wouldn't really help when you have many VIs opened.

When I work on MacOS X, spaces + expose are quite helpfull when you have less than 30 VI windows ; expose-like apps I've tested in windows are not as good, that's a real shame. Open expose was not too bad but I eventually left it and now I use the MS "advanced alt+tab" to be found http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx' rel='nofollow' target="_blank">here.

Hope this can be of interest.

You don't have to place the system frame inside the cluster. Instead you can replace the cluster frame with a system frame. Check it out. Credit goes to Michael who showed us how to do this in a post I can't find

Great tip !

Thanks for sharing

Here is what I get in LV 8.5.1 :

It is locked by defaukt and you have to unlock it.

QUOTE (Suneel @ Sep 12 2008, 05:46 PM)

Thanks...

But its giving the same error.....

I have LV 8.20 and it works fine for me

For the user account you created, did you uncheck "Lock account" in the Domain Manager ?

If not, try to do it.

Otherwise I don't know..

QUOTE (Suneel @ Sep 12 2008, 05:21 PM)

Can you save the VI you have tried to 8.2.1 and upload it.

Sure

QUOTE (Suneel @ Sep 12 2008, 03:50 PM)

Hi

I'm getting an Error when i'm trying with it. The Error code is 1088 and it says "Invoke Node in Untitled 6 Method Name: NI Security:Get Access Rights". I'm using LabVIEW 8.2.1.

Regards

Suneel

Hmmmm... It works for me in LV 8.5.1.

Are you sure you defined Domain/Group/Users with the Domain Account Manager ? When you create user, you need to add them to a group

Suneel,

I don't know exactly how it works but look, the ACL parameter type is a string (not a string array) so I guess the expected input is the user name as a string and the output will be this user's access rights. See :

hope this helps

QUOTE (Suneel @ Sep 12 2008, 01:21 PM)

Hi All

Can anybody let me know how to give the "ACL" Access Control List in the "NI Security:Get Access Rights" Invoke Node.

Attached is the image of the Invoke Node for reference.

Thanks in Advance.

Regards

Suneel

Hello Suneel,

I haven't tried it but I guess you have to use the DSC module function, located in DSC Module > Security, there you have functions to get the group list of a domain and the user list of a group.

I assume you will have to define domains, groups and users to get it to work.

Hope this helps

It's below my standards for a clean diagram, but not by much.

[..]

The same for me , I am quite demanding with myself about having clean diagrams, one things IMO that could improve the auto diagram clean-up is having wire labels ( ). When I try to clean up a diagram my free texts (code documentation) are often moved in a way that bugs me ; if I could bind my doc texts to wires, I think it would help.

Yes, you are not the only one !

I also went into the process of making core subVIs re-entrant, to helps with this I wrote a small piece of code that checks all the VIs in memory to see if they are re-entrant or not :

I agree it would be cool if LabVIEW could automatically add a "re-entrant glyph" on the VI icon, but until this feature comes I do it myself.

Hope this helps

Thank you Neville and Karissap !

Hi all,

I saw this article on NI knowledge base dealing with how to get the PXI controller's internal temperature but it is restricted to a 819x and 818x controllers.

I have a PXI 8106 and I'd like to monitor it's temperature to be able to disable some intense processing when it gets over a certain value.

How to get that in LabVIEW 8.5 :question:

Also, I noticed that MAX shows the current temperature for each DAQmx board plugged in the PXI chassis - and yes the temperatures of 2 boards are different - so I guess there will be a way to monitor each DAQmx device's temperature from LabVIEW.

Anyone knows how to do that :question:

It also lets me "see" the error after the fact, like when the customer from two years ago sudenly runs into a problem.

I can't count the number of times engineers have returned from delivering an app saying "I love that Event Logger!"

Ben

I totally agree with that, you can't seriously ship a system to a customer without some kind of event logger.

The time spent on this is saved hundreds of times when you have many system out in the industry !

I'm sorry it doesn't help... I know how annoying this issue is...

Apart from upgrading LabVIEW and working on a USB external hard drive and copying twice a day to the network drive until you can upgrade. I do understand it's a workaround you might not like but that's what I did during 3 month to get ride of the the ducks
