Real Time Matching of UCM-OEDQ

Hi,
How does Real time matching process is executed in UCM-OEDQ?
Query is: when we're trying to search the record, how exactly this is done? When We have a record which is to be searched (driving record), is that driving record stored anywhere in UCM in intermediate stage? How that is sent to OEDQ and how the matching record retrieval is done?
it will be a great help if anyone can throw some light on this query.
Thank you.
Regards,
Zankrut.

What is the best way to match clip and sequence settings for real-time editing?

I am a long time FCP user and trying to make the After Effects workflow a little smoother by utilizing the Adobe suite.
One of the most valuable things I miss about FCP is that when I drop a clip in a blank sequence (no matter what the settings of the seq) it will ask if I want to match the settings of the clip. This ensures that no rendering is required to quickly edit the video in real-time.
Is there a plugin or function in Premiere CS4 that I am missing that will afford me this feature? Currently i am doing everything I can to match the clip settings when creating a sequence, but sadly i'm still having to render the timeline to preview the edit.

And in CS4, if there is not a matching Preset, you can choose the Desktop Preset, which will allow you to customize nearly every attribute to match your source footage. The name is a bit of a misnomer, but has been around for a long time. I would have called it the "Custom Preset," but Adobe never called.
Good luck,
Hunt
PS - I just learned something new about CS5 from Curt, because of your question - thanks!

Waterfall plot acquired in real time doesn't match when it is read offline.

Dear fellow LabVIEW experts,
I'm in need of help regarding the waterfall plot in LabVIEW. I acquired vibration signals of a CNC router during idling. The accelerometer was attached to the tool spindle in proximity to the rotating tool. Using a LabVIEW program (LV 2010), I saved my data (using write to spreasheet function) and I also had a waterfall plot showing the vibration spectrum built up as I was collecting the data. I used the Print Screen function on the keyboard to copy the waterfall plot (collected during real time data acquisition) and pasted it in a Word document. Then, I had another LabVIEW program that was able to read back all the data that I've saved including a waterfall plot that was used to reproduce the vibration spectrum that I've collected. After I read back my data (offline), I compared the vibration spectra between the real time and offline. The vibration spectrum that is collected during real time is supposed to match with the vibration spectrum that is reproduced when reading back the same data.
My problem is this, when I changed the location of the accelerometer or the vibration sensor to a new location (a bit far up and away from the rotating tool), the real time and offline vibration spectra didn't match in that the offline one showed some additional frequencies or peaks that weren''t there when I was collecting it in real time. Does anyone know why this happens?...Is it something to do with the buffer?
I've tried my best to explain and I hope someone out there is able to explain this situation.
Really appreciate any helps.
Thanks.

File not found when trying to call a dll on LabVIEW Real Time machine

I have a dll called "DLLRTTEST" that I've written, and have succesfully called on my host machine. I'm now attempting to call this dll from a vi that is located on my real time computer. Currently I get an "Error 7 occurred at Call Library Function Node in DLLRTTEST.vi." message upon execution
In the attached screenshot I'm trying to ensure that the vi I'm running is in fact located on the real time system. I then use a "Check if File or Folder Exists.vi" to confirm that the dll that I'm about to call does exist on the real time system as well. However, I still receive an "error 7 file not found" error from the Call Library Function Node.
Any help is appreciated.
Solved!

As nathand already mentioned, depending on your C toolchain your DLL will depend on other DLLs. Usually the according msvcrtXX.dll that matches your Visual C version, if you use Visual C, other runtime DLLs if you use a different C environment. These runtime DLLs are even necessary if you do not call anything in any of your functions, since the DLL makes various initialization steps when it gets loaded and that references some C runtime functions nevertheless. Compiling and linking the DLL with static C runtime is usually also not a clean solution since the linked in C runtime will then reference Windows APIs that are not available on LabVIEW RT.
Depending on your version of LabVIEW RT you will have some mscvrtxx.dll files in your system directory but it will be an older one than from the latest Visual Studio version. If you can compile your DLL with that Visual Studio version then you should be fine, but could possibly run into new problems if you later upgrade to a newer LabVIEW RT version. Installing the C runtime distributables from newer Visual Studio versions is unfortunately also not a solution, since it references many (undocumented) Windows API functions that are not available in LabVIEW RT.

How to count occurences of a certain string in incoming real-time data? Also displaying RTC data. Current VI included

I use LabView student Express 7 on a Windows XP system.
Time-frame: we are doing final integrations for our balloon experiment today. We just got told that the press wants to view real-time data, which we haven't programmed for. I need help to get a working VI at the latest by 25.02.2004 before 0800(morning) (GMT+1).
Note on license
It is a student balloon flight, and the data will not be used in scientific work, so the I am not breaking any license agreements (I hope).
Problem synopsis:
The balloon continually transmits data at 9600baud. The data is a semi-repeating header followed by a constant lenght data-package arranged like this:
BEXUS[h][m][s]BEXUS[h][m][s]
[Raw binary data, 7channels*8sub-channels*8bits]
What the groundstation is doing right now:
Take all incomming data and save (append) the data to a file without any data-handling. (We figured we would go post-processing).
What I need to change in less than 24 hours:
- Add a "package" counter
- Add a display of the clock data (RTC)
How I planned to implement the changes:
-RTC display:
The RTC data is in BCD format, since that means that if you look at the data as hex numbers, you get the hours and minutes and seconds out in "clear text". That is 12 hours is 0x12hex. I figured that I can do a match pattern BEXUS and pass the "after substring" to another match pattern BEXUS from which I feed the "before substring" to a type-cast VI (casting string to u8) and displaying that, which should give me a display of "123000" for the time 12:30:00... I couldn't get it to work at all when I tried out the supplied "beta" vi.
- Package counter:
Counting how many BEXUS that gets detected and dividing by 2. I don't know how to do this. I've looked on the forum (a good thread on the problem: "how do I count the number of *'s in a string") but these use either loops or arrays... and I'm not sure how this works when I'm getting the data in at realtime. I cant make an array and then count it, since then the array would grow fast and possibly interfere with saving of the data??? Saving the data is critical.. without that file we cant do post-processing.
Since my time is so limited (I'm not even supposed to do the groundstation software but they called on me in the last minute because no-one else had time/wanted too/could do it) I hope that you could make an exception and provide me with working VI's (based on the one I have attached) so that I can show something to the press! (Free comercial for NI!! Since the student version shows the National Instruments water-mark on all VI's!!! Possible TV time!!)
Thanks!
PS: even if you are to late (after 25) post anyway!
Why:
-I can learn from it
-the launch might be delayed due to weather conditions
-others might find it amusing!
Thanks again!

BexusII_groundstation.vi ‏46 KB

I have a valid example data file attached to this thread.
If you open BEXTEST.bin in a hex-editor of your choice, you'll see the BEXUS as 42 45 58 55 53 and then the time as 00 28 09 etc.
I couldn't get Joe Guo's VI to work. It doesn't count packages correctly, and the time is not displayed correctly either.
The file was saved using a straight save to file VI.
The data is from actual launching area tests performed a few mintues ago. The time displayed is "On time" e.g. how long the gondola has been powered up.
I have a spare T-junction, so I can hook into the balloon real-time data as we fly, in case anyone care to see if they can figure out why the latest version of Joe Guo's program is not displaying correctly.
I will monitor this
thread during and after flight to see if anyone can make it in time!
Thanks for the great effort!!

Real-Time Application doesn't run; source code works fine

The short version is I'm programming a cRIO and apparently the RT code isn't running after being deployed and I can't figure out why. This is further complicated that I'm doing all this remotely and I don't have direct access to the unit since I'm 500 miles away. I'm working through a couple of other guys who know some LabVIEW, but neither works at the site so they have to explicitely travel out there every time I have a bright idea.
I was out there a few weeks ago. During this time I created a simple cRIO code, since I'm new to cRIO, that allowed the user to move a control and change a graph. It worked fine, but I should note it did not have an FPGA component. After that I worked on the real code, which reads some sensors, displays the results on a UI and logs the results. This did have FPGA. I used it in the LabVIEW environment and it worked fine, but I ran out of time before I could complete a release version and deploy the RT as a compiled application. I sent them the release version later, my contact deployed it but got network stream errors when running the UI.
After hours of looking at network problems and sending over debug versions, I tried creating a log on the RT level so I could see what was going on. The log doesn't even open, even if it's the first command in the code. I pored through the forums and found http://forums.ni.com/t5/LabVIEW/cRIO-Troubleshooting-creation-and-deployment-of-startup/td-p/1956475... which took me in a new direction.
I had my contact use the RT debug console and when he pulls up the RT front panel, it shows a broken run arrow. He clicks it and nothing happens -- no running, no bug list. If he pulls up the bug list manually, it's empty. Again the RT works fine if you run it through LabVIEW and not as a compiled real-time application. He also noticed that the Open FPGA VI was grayed out on the block diagram. No other icons are.
So the problem appears to be that the compiled RT application is getting some kind of error but not telling me what it is, and it seems to be related to opening the FPGA. I've recompiled the FPGA and RT. I've had him recompile the RT himself, but not the FPGA because it would take hours. He's downloading everything correctly to the cRIO. The RT is set to run automatically. He's rebooting the cRIO every time he deploys the RT. They have LabVIEW on a computer there but it doesn't have the right drivers to run the code from the LV environment. I'm resisting having them install the dirvers because downloading big files is complicated there due to security restrictions and a lousy network connection at a remote site. Besides that doesn't solve the problem of the RT executable not running the same as the source code, which according to the thread above appears to be a thing.
The latest thing I'm trying is that I sent him instructions for how to build a source distribution from the project I sent and try deploying that to the cRIO. Even if that works I'm not sure that's an acceptable solution because I assume running the VI rather than the EXE is slower, and they need speed on this project.
I simply have no idea where to go from here. I probably need to get direct acess to the cRIO and I might be able to convince them to ship it to me so I can figure this out, but I'm not sure where I'd even start other than the standard voodoo debugging of "try stuff at random until something works". I'm open to suggestions if anyone has managed to solve this before.
Code snippet of the first part of the project is attached, though I'm not sure how much good it will do. I'm really stumped and the client is getting frustrated with how much of the budget is going to fix this.
Solved!

Have you checked the cRIO error log? Usually I'd access it through the LabVIEW project (right-click on the target, don't remember the exact menu options and I don't have the RT toolkit installed on this machine to check), but it must be stored somewhere on the cRIO as well, although I don't know if it's in a human-readable format.
Which cRIO are you using? What exactly do you mean by "debug console"? (This may be related to the cRIO - the newer ones have video out, although I don't know if that's what you're referring to.) With a broken run arrow, you won't get an error list unless you're running in the development environment.
Have you confirmed that the software installed on the cRIO matches the version you're using for development, including patch level? Get someone to connect to the cRIO with Measurement and Automation Explorer, and get a list of the software installed on the cRIO.
Sounds like the ability to connect with a remote debugger would be helpful here, if you can get the right drivers installed on the machine with LabVIEW that's connected to the cRIO. Make sure all driver versions match what you're using. Any chance you could then do a remote desktop connection from your work site to the remote LabVIEW machine?

Real time pattern recognition

I'm trying to build a pattern recognition system, so that I can detect in real time "STOP" traffic signs. I've build a template and a script using Vision Assistant, an then I used the "Export to VI" option. I've been trying to modify the generated VI, to add the webcam part. I can't figure out what's wrong, as the program captures video, but the pattern recognition part doesn't behave as I want,it just applies some image filters and displays the first captured image. I'm a begginer in LabVIEW, please help me figuring out what's wrong. It should show the captured video, marking the pattern if one is found. Thanks

Hi Nathan,
Thanks for the reply. I've managed to solve some of the issues. I've given up trying to do the geometric matching real time. I just want to do this against a couple of local images. My big problem right now is that I can't manage to display the overlay over the initial image, as this gets distorted in the process (applying the color threshold, the equalize feature and so on). I guess I don't understand correctly how the matching algorithms work. I would greatly appreciate if you could point me in the right direction...basically, I want to display a rectangle overlay over the initial image. I have a couple of questions from there on, but I want this solved first. I've attached my latest VI, the VisionAssistant script for detecting the signs and an image I use to test. Thank you

Real-time process slowly filling up Postgres DB space

I have a real-time job which takes data from a JMS queue, processes the data, and then applies inserts/updates to an Oracle DB. In the task definition for the process Results drill down is set = "None" yet the Postgres DB grows substantially as the job runs. Also the following SQL seems to find a row per JMS message processed...
select count(*) from pg_stat_user_tables where schemaname = 'results'
Anybody any clues as to what may be causing the DB to grow?
Cheers
Jon

It looks like we're going to have to - Postgres has just died...

Real time : File Adapter : query

Hi Folks,
At development time( file adapter) we test our scenario by creating a sample XML file using message mapping tool .
The type of message we get from this contains Message Type tag with namespace Attribute.
<ns0:MT_XYZ xmlns:ns0="urn:xyz">
My question is in do in real time we need to tell them that create message type with the anmespace attribute we are using ? and also how to suppress namespace and will it bring any complications in the process ?
Regards,

Santosh,
1.     When using the File adapter and Content Conversion to read the file into XI, you can allocate a specific message namespace
2.     If the namespace does becomes an issue for your scenario then use an additional mapping step to remove the namespace. For example we have the
Mesage Type MT_NAMES which has a a type of NAMES
Subelement NAMEREC (0 .. unbounded)
Subelements NAME1 and NAME2
Sample xml
<?xml version="1.0" encoding="UTF-8" ?>
<ns1:MT_NAMES xmlns:ns1="http://namespace">
<NAMEREC>
<NAME1>AAA</NAME1>
<NAME2>BBB</NAME2>

Workflow - real time

Hi,
Can some one give me common workflow senarious in the real time concerning vendor/customer/material. 2 or 3 senarios on each of vendor/customer/material will help me to have good insight of each specific workflows.
Thanks

Hi
a typical example can be:
Start-> Validate->Process-> Match-> Merge-> Approve-> Notify->Syndicate->Stop
This workflow can be used for validating all records in MDM based on the validation rules, editing records which fail validation, finding if the records are duplicates and then approving by the business. Final step is to syndicate approved and clean golden data to a remote system like ECC where transactions are done on Vendor/customer/material master data.
This way we ensure only approved de duplicated records are passed on to ECC.
MDM offers a host of such features and supports looping, branching, Grouping of steps which are used for modeling workflows.
Hope this helps.

Handling sequences in real time data transfer.

Hi,
We are merging two databases (real time data transfer).
One is oracle 8i and other is 9i.
Both databases are having some tables with same structure.
We want to transfer data from table in one database to table in other database.
We are implementing this functionality by using Adevanced Queueing.
Both side tables are using different sequences for generating primary key values and currently contains large volume of data.
The problem in inserting is, when we will be transferring any record from one table to other, the primary key value (sequence value) generated in both tables will be different.
So, if any particular record is updated in one table, How can we update the same record in other table ?
(As the primary key value would be different).
Thanks,
Shailesh

There must be some common data in the two tables, that identifies the record. That is, ignorng the sequence generated PK, how would you tell that two records referred to the same thing? You need to ignore the PK values, since they are meaningless surrogate keys, and use the natural key in the data to match the two talbes.

After Effects will not RAM Preview in real time

Recently I have started working on a new project and can't work on it because my RAM Previews are not in real time anymore. I have only had this problem since I started this project a few days ago. Every other project I have done I've never had this problem before.
I have 10 GB of ram allocated to After Effects, my clips are in 59.94 fps which I have set the composition to as well. When I ram preview it tells me 50.019/59.94 I know what this mean, I understand it's telling me to change my composition's frame rate to 50 frames, however if I do this then music plays too slow. Right now my problem is that the clips aren't playing fast enough for me to see if my editing and time syncing is acurate. When I render the video everything is synced up fine but this is making my editing very inconvenient and I would like a fix please. I tried: Clearing my disk and media cache, unchecking "render multiple frames at once", taking off all effects on the clips, using different clips, AND even reinstalling After Effects CS6 but nothing has worked. I really badly need a fix to this problem. Any help would be greatly appreciated thanks!!

> The clips are in 59.94 frames, so the composition is in 59.94 frames. If when I upload to the internet it goes down in frame rate so be it.
You are misunderstanding the typical video workflow.
Composition setting are supposed to match the characteristics of the intended output, not necessarily the characteristics of the imported footage. This is how you ensure that what you preview exactly matches what you output and what your viewers will see. Consider, also, that most compositions use assets with many different frame rates, sizes, etc.
> I do have a large monitor but I've been using this monitor since December and haven't had a problem with it until now.
Great. But you're having a problem now. And it's because of a bottleneck somewhere between your RAM and drawing the pixels to the screen. One more reason that this might be happening is that you're running a GPU-heavy application; note that web browsers can also be GPU hogs these days.
