Anyone know if Real-Time or FPGA can be downloaded yet?

Activated fine here but I did have to reboot for some reason.

I can only hope that LVOOP will extend to Real-Time targets in 2009.

Actually, it is a standard design pattern in LabVIEW. NI has presented it in many places. Most recently, it was in the spring 2009 Developer Days conference presentations for "Design Patterns in LabVIEW." The slides are here.

Wow! On slide 55 is a picture of Custy's. I live very close to Custy's but I haven't eaten there yet.

You didn't have to register for sessions before. Did they change something this year?

Last year I used Google Calendar to schedule all my events. I had SMS alerts before each session with room numbers in the SMS. This helped me keep on track and spend less time worrying which session to go to next.

One advantage PXI has over PC is support for new products. NI always seems to release new products for PXI and may or may not release PCI versions of those products. A perfect example is the R-Series Virtex-5 FPGA cards. There are still no PCI versions of these cards yet

Great idea, didn't know you could do that. I guess you could call that pseudo-scripting. With VI scripting being available since 7.1 it never dawned on me to try a text ring.

I do that all the time without scripting. Read the file, load the string values into a text ring, then replace the text ring with the enum. Or did I miss something?

There are quite a few good use cases for scripting. I once had to create a enum constant with over 500 elements. Using the Edit Items... dialog box would have taken forever. The 500 enum values were already in a text file. Using VI scripting I opened the text file and created the enum.

What are folks really intending to do now with scripting that has such value ? You can talk about what you plan to do, but if you never allocate time to implement the idea then scripting isn't really all that valuable to you after all. Enough talk, how about you show me your really useful creations ! (I'll accept Auto wiring scripted tools only if they produce a similar wow factor to the BD cleanup feature !)

Now that scripting is legal, should it be moved out of Rusty Nails?

In the mail today I got the Instrumentation newsletter. Page 25 talks about VI Scripting in the article "How to Integrate your tools into the Labview Environment."

From the help:

And Array Elements

Returns TRUE if all the elements in Boolean array are TRUE or if Boolean array is empty. Otherwise, the function returns FALSE. This function accepts an array of any size but returns only a single value based on all values in Boolean array.

I tested this yesterday with a label on the block diagram in 8.5.1 and it worked fine. I did not try the FP yet.

I for one would purchase a license for scripting if it ever gets released as a product. Releasing it as an extra price adder for those that need/want scripting should keep the support cost for NI to a minimum compared to releasing for everyone.

Out of curiosity what does LabVIEW state is the changes in your project?

An attribute of the project was changed.

I haven't worked with this, but you might be interested to know there are some experimental drivers that can be found on NI Labs for Allen Bradley PLC's.

There are some VIs here on lava too that are more open then the NI ones. They are not OPC but communicate with the Ethernet IP protocol which is what most OPC servers would be using.

I have the same problem here in 8.6. I've always blamed it on the order of dependencies changing in my project. Every time I do a text based compare of the old and new lvproj file this item is always in a different place:

<Item Name="semaphor" Type="VI" URL="semaphor"/>

I do not have autopopulating folders either. Why do dependencies get saved in the lvproj file? Is there any way to turn of saving of dependencies in the lvproj file?

If you need to do Profibus with Labview then check out:

Hi,

I have to interface Lab View with a CIF 50 Hilscher Profibus.

I read through some of the documents provided by Hilscher, it talked about Sys Con, OPC servers etc etc.

Through this profibus i have to control a valve box through RS-485 communication.

The first task is basic read/write.Through lab View i have to read the number of bits through CIF 50 bus in turn to the Valve box.

Can anyone tell me where should i begin?

I have the same problem, the time required for a team might be too much for me. Were starting a new program here in CT called the "Regional Technical Expert" program. This way area Labview experts can provide help to all the Connecticut FRC teams.

I looked into the teams in Oakville a couple of months ago. (Used to live just down the road from Appleby College) The presentation at NI Week got me pretty fired up to get involved.

Unfortunately some pretty big projects came up at work and I didn't feel I'd be able to commit the time required for this round. Hopefully I'll be able to get involved at some point though.

Hey that was a good hint! I tried my laptop and it worked!

I guess there are a lot of things connected internally via USB in my DELL desktop.

Thanks!

Maybe a note should be added to the http://digital.ni.com/public.nsf/websearch/9209361E17708D548625744A007FF353?OpenDocument' target="_blank">NI link about this.

I would bet there is something wrong with DeviceClasses in the registry of your Dell desktop. Did could try deleting the USB flash disk in the device manager. Then, remove it and re-insert it so windows runs the found new hardware wizard. This might fix your registry and MAX might work.

There is a thread over at the NI forums, and a CAR, about this issue here.

NI does have support for licensing a LabVIEW Real-Time application to protect a deployed application from being copied and run on another similar or identical set of hardware.

Hi,

I'm working with compact RIO system and looking for a hardware dongle to protect my application from beeing copied to other systems. Is there any dongle or other way available? The system has only RS232 port but no USB. The OS is VxWorks, so I guess any DLLs are not working on this system. Any idea?

Thanks!

The _Web Document Tool.vi is password protected in 8.5. Are there other ways to access the private vi server call?

You could use scripting workbench.

I've never seen mention of them not working in Windows. I've had zero problems using them on the host (i.e. windows) side in my applications.

1.5 GB / 45 min = 0.0333 GB/min or 555 KB/sec. I have never seen a file transfer with RT FTP of 555 KB/sec wired or wireless with my cRIO. I only get 450 KB/sec over a wired network.
