I am trying to read and write the digital output on an NI9476 cRIO device in an NI9148 cRIO chassis using the shared variable VIs. I want to create a generic driver that can access any cRIO hardware on the network provided I know the IP, module slot and port on the device I am interested in. I created a simple VI to do this. When I run it, I don't get any errors, but it does not appear to control the output I am targeting. Has anyone else done something simular? Is there something simple I am missing? This is the first time I have messed with cRIO. All our current setups use cFP but we are interested in changing to cRIO hardware in the future.

Here is my code:

thanks for any ideas!

This is off the top of my head as I don't have LV in front of me, but I think your URL might need to be set to ni.var.io:// instead of ni.var.psp:// when configuring outputs.

This is my first post in months...but I haven't forgotten you LAVA. I still lurk frequently when I need information - just don't have much time to post.

I have been working at Microsoft (Redmond, WA) now for just over a year as a vendor/contractor through Northwest Contract Services (NWCS). It has been the best career move I've made and I wanted to share the opportunity with others in the area that might be looking for a change.

NWCS is currently seeking qualified candidates to fill the following positions:

- LabVIEW developer and Hardware Test Engineer - preferably with some supervisory/team lead experience

- Hardware Test Engineers - EE with test development and design verification experience

- Manufacturing Test Engineers - EE or ME with test fixture design, test software and test equipment experience

If this has peaked anyone's interest, please PM me and I'll make sure your resume gets to the right place. I know there are a lot of talented individuals here that could be a great fit (Full Disclosure: I'm not a recruiter, but I might get a little kickback for referring someone who does good work )

There are cool kids here?

I guess so...they let me in

This sounds intriguing. I can't wait to check it out...now if only the cool kids will let me into the group.

Could someone please check if changing these settings

- increasing/decreasing scroll speed and

- disabling/enabling hor.scrolling

has any influence on Your LV DevSystem?

Thank You in advance!

Stefan

I didn't see any change in the LV environment when I changed the scroll speed in windows. I did find a thread here on the dark side that traces a scrolling issue back to a custom pointer installation.

If you hover directly over the horizontal or vertical scrollbars and move the wheel will it scroll?

Not yet ...

If no one else is ever experienced that issue Reinstalling would be the next step.

I have been using LV2009 with Win7 for quite a while on multiple machines and have not seen this issue. I'd go with a reinstall.

-Toby

I'd appreciate a kudos or two over here.

I have wished for this in the past as well. It seems messy to use station globals when many projects will never use them.

-Toby

I am trying to trigger an event each time the boolean indicator changes states. The boolean indicator is connected to a digital DIO. Each time the state is changes from low to high i must read the data and each time it changes from high to low i want to read data as well. so on the state change i want to call the read function.

can anyone help me out please? thank you:)

One easy way to accomplish this is to write to a Value (Signaling) property node rather than to the indicator itself. That will trigger the event, and you can use the OldVal and NewVal event terminalts to determine if the value has changed. See attached vi.

BoolIndEvent.vi

Congratulations!

Do you have any notes you would like to share to help those of use who have to re-certify (next week) ?

You know I can't say much Ben, but here's what I will say...

I was actually surprised. I thought this exam was much easier than the CLD. Perhaps it was just the extra 2 years of experience (and quick drop certainly helped as well). I actually finished everything to my satisfaction with about 5 minutes to spare.

Since I didn't really know what to expect I went back and reviewed the 3 CLD sample exams again. That turned out to be a really good idea. Remember that you are allowed to use the built in LabVIEW Templates. I spent some time practicing building various architectures starting from the templates and adding in things like error handling so that I was able to very quickly generate a framework during the test.

The other thing that I had to keep reminding myself is that I didn't have to actually write the code, just define the inputs and outputs to each subVI and wire them up and then add a brief comment as to what the subVI should do. I ended up actually coding up one of my subVIs as a sanity check to make sure that what I wanted it to do would actually work...it did.

And most of all...Good Luck!

I started a new job yesterday that I think is going to be great, and I just got my CLA results...I PASSED!!! Life is good!

I'm looking for ideas on new medications, new research, anything credible that the LAVA brain trust can suggest. Please keep your recommendations based in science and provable facts.

I've heard there is a link between drinking homogenized milk and heart disease...although admittedly I have done no research on the topic. Just thought I'd throw it out there so you can look it up if you are a big milk drinker. I probably should do some research because I drink quite a bit of milk myself.

And not wanting to sleep on the couch?

Well...there is that

I just ran across this article and thought it was pretty neat...looks like LabVIEW in the picture.

Children With Autism Show Slower Pupil Responses, Study Finds

What is a "Coupon" ?

Attendees to the LabVIEW developer days get a $200 coupon or voucher that can be applied towards any NI training or certification exam.

And I confirm that magnets are kind of magic: at my daughter's birthday party I filled very tall bottle with water, put some coins (I had to select them before) inside and gave children neodymium magnets. Getting the coins out using magnets attracted them for half an hour!

Sounds fun, but you'll have to find some foreign coins for this trick. US money is not magnetic. It's always a good idea to run a magnet over any rolls of coins before taking to the bank to make sure you didn't accidentally let some Canadian pennies slip into the mix.

I figured out what was happening. I was switching back to the SequenceView using the ExecutionClosed callback, but wasn't checking the number of executions that were open. Opening my autolaunching sequence file would open two executions, one to open the file and one that was the actual execution of the file. As soon as the file was opened, the first execution would close triggering my UI to switch back to the sequence view. The other execution had already started running the sequence file so it would continue to run in the execution view but I couldn't see it.

I now use ApplicationManager.Executions.Count and only switch back to the SequenceView if there are no executions open. This works well for what we are doing.

Anyone know of a good online training resource for GIMP? I don't just want a manual, I'm looking for something that will teach me through exercises.

There are quite a few video tutorials on youtube...some better than others.

We have build a test system that is running TestStand 4.2 and the code modules are created with LabVIEW 9.0. The SW is running on a PC with Windows XP.

We are currently using TestStand Simple Operator Interface (LabVIEW version) to run the tests, and it is with the Operator Interface that we are having a problem.

We are experiencing the exact same issue with TS4.2 and LV2009. I'll let you know if I figure out what is going on.

TestStand 4.2

LabVIEW 2009

Windows Vista Business 32-bit

My sequence file is using a SequenceFileLoad callback to automatically start its own execution using the TestUUTs entrypoint. This is accomplished by calling the Engine.NewExecution method. The problem I am having is that my custom LabVIEW user interface is not switching to the execution view when the execution begins. If I manually start the execution using the TestUUTs button, the execution view is displayed.

In my UI, the change from the sequence view to the execution view happens in the DisplayExecution event callback as well as the StartExecution event callback. I also tried the Executionchanged event callback but realized that it did not apply in this case. The complex UI that ships with TestStand works correctly and, as far as I can tell, I am using the same event callbacks to handle the change in my UI.

Any ideas? What am I missing?

FULL DISCLOSURE: Cross post from NI Forums

I don't know if this had been discussed yet, but I just found out about it yesterday and I hadn't seen it here...In LabVIEW 2009 there is a new ini key:

skipSVNFolders=true

This will cause LabVIEW to skip over your .svn folders when doing a mass compile.

I imagined you imagining a NI employee randomly reading LAVA and being like "Oh I knew I forgot something" and frantically writing code and then you writing a post about it -- crazy.

I imagined you imagining hooovahh imagining a NI employee...wait...this is getting out of hand
