Hi Frank Noe,
Have you connected the device and set it up as specified in the manuals? A good place to look to ensure you have taken the proper setup steps is the 1464 RT's getting started guide. Pay particular attention to the steps listed on pages 8-12. If you have everything connected and setup properly, and are still encountering this issue, take a look in the 1464's user manual in appendix D. On pages D-4 and D-5, the manual lists troubleshooting steps for the device not being listed as a target in VBAI. Hope this helps.

Hi Shada this can happen if you are including additional installers to your installer for example DAQmx. When you are doing this the installer has to include other files like MAX (Measuremente and Automation Explorer). Probably when you installed Vision Builder it updated MAX, so when your installer is trying to Include MAX, its asking for the source where it was installed in your computer in this case Vision Builder.
Here you can cache the information so its not asked again, or you can download a newer version fo DAQmx, so it will update MAX and change de dependecy.
You can find more details about this issue in this KB:

B2MML with real time data

Hi All
I want some B2mml files with real time data.
So exact( maintenance infromation and Production) B2MML that is coming from MIS.
So if anyone have some information regarding this please tell me.
Thanks in Advance
Ramshanker

Hi, Ramshanker.
In the cases where the plant system is directly delivering B2MML documents (such as with certain products from Wonderware, Siemens, and some others), using the data in xMII is quite straightforward.
1) If the B2MML message is not "standard" B2MML (be aware that very few plant vendors use the baseline standard - most have a number of specific extensions), you can add the vendors' schemas or B2MML example documents to xMII by adding them to a ReferenceDocument folder on the server.
2) In xMII BLS, create a transaction (let's assume you called it B2MMLHandler) with one input parameter, of type "XML" (let's assume you called it "B2MMLDocument"). Add a "ReferenceSchema" or "ReferenceDocument" action, and configure it to load the vendor's B2MML format. Use the "assign reference document" menu option to assign this format to the transaction input.
3) You can now use the B2MML document to perform analytics or to map from the B2MML document into any RFC or BAPI calls or ESA service calls from within BLS.
4) The plant system system should "post" the XML data to an xMII transaction using the "Runner" URL as in:
http://<yourserver>/Lighthammer/Runner?Transaction=B2MMLHandler&InputParameter=B2MMLDocument
Of course, if the MES system isn't capable of posting the documents and they are available on the file system, you can use the xMII file actions (or remote file access via FTP) to access and load the B2MML documents, perhaps at a scheduled interval.
Hope this helps get you started in the right direction.
Best regards,

[Solved] QJackCtl won't start in with real time.

Hey all,
I'm having a problem with QJackCtl, I got my version from Extra. The problem is that for some reason Jack won't start in real time mode using QJackCtl. Real Time is checked and marked under the set-up tab, but that little piece of info doesn't seem to make it to jackd. If I start Jack through CLI it works with real time, but not from the GUI.
I figured this out by starting JACK from the command line and then starting QJack. When I would do that it would be running in real time just without the rest of my settings (buffer,periods,sampling rate, etc). So in my head there's an issue with QJackCtl. I've tried to find a solution, but I can't seem to find one. This isn't the first time I've set JACK up on a system, but this is the first time I've had this problem.
The rest of the system is set up and ready to go. Rt Kernel, limits.conf and all other tuning is done.
Is there something I missed when setting this piece of software up? Any ideas?
Solved Edit:
Okay, so right after I posted this I got a crazy idea. When you enter setup in qjackctl on the first page there's a box for server path. The path defaults to "jackd". On that line I added "--realtime", so it looked like a basic CLI start-up of JACK and now it works!
So, if anyone else has this problem go to the Setup tab, in the setup window on the line that says Server Path it should look like this:
jackd --realtime
It worked for me and I hope it helps somebody else out.

Which volume? Assuming you're on the most common usecase (single hw audio device) then whatever command line you use (amixer for example) it'll work fine, it'll control the volume of the device rather than the pulseaudio plugin (so other playing apps get affected as well, which is probably what you want). The 'global' volume so to speak.
For multiple hw audio devices it gets tricky though.

RMAN in active data guard with real time apply ON without a catalog DB

I would like to know whether I can take RMAN backups (both level 0 & incremental) in active data guard with real time apply ON without a catalog database. version is 11.2.0.3.2. Will it make difference in the control file of standby syncing with primary? Can I use these backups on primary to restore and recover the database(including control file backup)?

Thank you very much msberg. Could you please answer the below queries as well?
Should I cancel Real Time Apply before starting RMAN?
Will it make difference in the control file of standby syncing with primary? Is it possible to use these backups on primary to restore and recover the database(including control file backup)? If possible, how will I do that?

RAC with real time knowledge

Hi, I'm interested in learning RAC and dataguard with real time knowledge......... please help me finding some training institution or peoples with real time knowledge
Thanks

The term "+real-time+" has a very specific meaning in Information Technology. See http://en.wikipedia.org/wiki/Real-time_computing for the basic details.
Oracle RAC is not a real-time database.. and nor does the "real-time knowledge" make much sense IMO...
Always difficult to get to grips with the nuances of the English language where it is your 2nd or even 3rd language. But it is important that we speak the same language and understand the same terms and concepts, in Information Technology.

Starting a Physical Standby DB which is configured with real-time apply

Hi,
I wanted to get clarification on the correct procedure for starting and stopping a physical standby database. The Dataguard documentation states the following:
1. Start and mount the database:
SQL> STARTUP MOUNT;
2. Start log apply services:
To start Redo Apply, issue the following statement:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> DISCONNECT FROM SESSION;
To start real-time apply, issue the following statement:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> USING CURRENT LOGFILE;
My configuration is using real-time apply based on the information provided by the RECOVERY_MODE column of the V$ARCHIVED_DEST_STATUS view. Should I execute both ALTER statements or just the second one. If only the second one, how will the database re-synchronize, especially after a long down time. Also, must I do anything on the primary database prior to starting up the physical standby?
I'm using Oracle 10g SP1 on a linux server.

No. But you can recover until the last arch file generated on the primary, then you cancel the recovery and then use query#2 to start applying real-time. Refer to Note:343424.1 on Metalink.

Software protection with real time clock

I'm trying get a secure real time clock information for licensing purposes ,I tried hardware dongle like hasp4 with RTC but I was not able not interface the dll and kept coming up with errors.Can anyone suggest a better of getting real time clock information or any available product which I can use.
I even thought of using the system clock but it's doddle to reset the system time.
Help is much appreciated.Thanks in advance

One possibility might be to force the computer to access an external time server of your choice and check the time from there.
This example shows how to read the time from a NTP server using LabVIEW.

How to build demo versions with Labview ?

Hello,
is it possible to design Labview applications in a kind,
that it is possible to generate "demo versions" of it ? Demo version in the means of feature-limited crippled versions of a full instrumentation software, where SOME hardware access is denied, but you can load and view and analyse data.
Of course it might be useful to compile this demo version with the Labview Application Builder,
What might be the business modell for demo versions:
A hardware manufacturer creates a Labview application which controls the manufacturer's components, and allows instrumentation and data recording. The application is not free but sold for extra money.
As pre-sales benifit, the manufacturer would like to send the (compiled) Labview application to future customers.
Now the problem is, that the customer has not (all) the external devices or PCI/USB devices,
on the other hand the hardware manufacturer does not want to give the "full application" as gilft to the customers.
Now with traditional software development with C++, Java, C#,
either a demo version is gained from the full version by replacing some module with hardware access by modules wth "empty" function body or with function body which return constant values instead of accessing the hardware.
In the world of process industry, usual process control systems may supply "alternative" values if the original device is not available.
What kind of software structure must I build with Labview, to do the same ?
Now the problem with Labview applications is
Labview applications depend on drivers. Drivers depend on hardware.
So if the FULL commercial version of the Labview program accesses a DAQmx driver, GPIB driver or any other hardware driver by a VI,
and often this means that a special manufacturer VI is used in the Labview program which does the actual hardware access,
how to modify the software to make a demo version
a) so that IF the customer buys the hardware and gets the hardware driver, he still does not have the full version
b) so if the customer neither has the hardware nor the driver, he still can run the Labview software and load an view data, push buttons, can execute menu items even can manipulate data ect, can use the manufacturer's VI
Unfortunately, it is no solution just to delete "some" of the VIs with hardware access from the distribution of the demo version, as this just causes error messages during the loading of the (compiled) Labview demo application.

Conditional Disable and Diagram Disable Structures
http://zone.ni.com/reference/en-XX/help/371361B-01/lvconcepts/cond_diagram_disable/
are indeed at least a part of what I wanted.
Anyhow, as such "suspended" VIs are often the *source* of signals,
so there must be an addtional method how to provide "alternative" signals for the demo version,
which does not make the administration / further development the full version too complicated...
For example: The VI for an external signal generator device is disabled, but alternatively it would be nice if the users of the demo version can get a fixed sinus signal instead...
How to do that with Labview and the "Conditional Disable and Diagram Disable Struktures",
and can I test this all even without Labview Application Builder, in the full development system ( so that I don´t need the compiler for frequent checking ) ?
Btw, with what version was this "Conditional Disable and Diagramm Disable" feature introduced ? Is ist already available with Labview 7.0, /.1 ?
Sincerely
Rolf

Configuring FCP to preview project in real-time on TV via Camcorder

Hey,
Somebody that I've worked with explained to me that it was possible to hook up my camcorder (GL2) by firewire to my iMac and also connect the camcorder with RCA cables to a regular TV so that the camcorder bridges the image of my project to my television so I can preview my project on a TV in real time.
He explained to me that I only had to hook up the camcorder and configure Final Cut Pro HD in the "Audio/Video settings" so that the video feed is streamed to the television.
Obviously, it doesn't work for me since I'm posting here, so I was wondering if somebody knew the settings I had to put in "Audio/Video Settings" to insure that I can see the video that I'm working on in real-time.
Thanks for your time!!
20" iMac G5 2GhZ 1gig RAM Mac OS X (10.4)

its a simple thing once you do it the first time:
assuming you have connected it all up,
go to FCP's View menu and choose "Refresh A/V Devices" (Opt-F12)
then View > Video Playback > Apple Firewire NTSC
then View > Audio Playback > "Audio Follows Video" (or Firewire DV)
then View > External Video > All Frames (Cmd-F12)

Issues with Real-time Playback?

Hello,
I am working on an animated film and I am having trouble getting my footage to playback real time in Premiere 6. It is making it impossible to edit.
It plays choppy. Will stop on a frame. Doesn't catch up on the edits.
Here are my computer Specs:
MacBook Pro
2.5 ghz intel core i7
8 gb mhx DDR3
AMD Radeon HD 6770M 1024 MB
OSX Lion 10.7.5
Sequence Specs:
24 fps

spuare pixels
progressive scan
24fps timecode
48000HZ
Footage Specs
24 fps
1980x1080
h.264
file size between 2MB - 300KB
Sequence length 4:18
I have trolled all of the forums to see if there was anything to change to no avail:
I tried both setting the Project set to MPE with GPU amd MPE with software. No difference either way.
Playback resolution is at 1/4
I've closed all applications.
Optimized my drive.
Restarted.
Updated to 6.0.2
Anyone have similar issues? Any ideas on my set-up?
Thanks,

I am sorry. I actually posted other questions here and I have always put my
computer info at the end of my questions. Yesterday I was browsing around
and I noticed that under the profile you created a specific place for the
computer info. So I thought that perhaps it would be the proper way to do
it . Apparently I did the vwrong thing. Also to ask a question on the web
is something that we all do without thinking anymore. Everything is free
and we take everything for granted with no intention whatsovere to take
advantage of anyone and neither did I in this instance. My apologies. I
will follow up with my computer specifications tonight when I get home from
work. Thank you.

How can I build a table with the time values of a timer from a while loop

Hi:
I have a question concerning building a table:
Every 100ms I read a value from a sensor (while loop with a timer). I would like to build a table with the actual time and the concerning value. For example:
0msec         1V
100msec     2V
200msec     3V
300msec     4V
etc.
If I use the Express VI for building a table, I always get the date and time, but I don't need the date and the time is in the following format: HH:MMS, which is nonsensical for me as I can't differentiate within msec. Can I change the format anywhere?
Can I also save the table to a file or even to an Excelsheet? How can I do that?
Thanks for your help!

Hi Craig:
thank you very much. To solve the mystery : ) :
I want to drive a stepper motor with a specific frequency. To get the current degree value of the motor I would like to measure the current time (from the beginning of the move on). (With a formula I get the degree value out of the time)
Concurrently I would like to get data from a torque sensor and from a pressure sensor. That's why I asked you about the time and the table. The measurement should start with the movement of the motor. How can I do that? Right now I have different block diagrams (different while loops) (see attachment) and I would like to put them in one.
I haven't done the block diagram for the pressure sensor yet, so there is only the one for the torque sensor and the one for the motor.
I also would like to set a mark in the table when the voltage value of an analog input gets under a specific threshold value. Is that possible?
I'm sorry, I'm a novice in LabVIEW. But maybe you can help me.
Thank you very much!

Producer/consumer architecture over network variables with Real-Time target.

Hi all,
I am maintaining a producer/consumer data acquisition program to be deployed on a real-time target. The main code is deployed to and run on the real-time target during experiments, but was having trouble because the program was originally designed to write all experimental data to disk on the real time during acquisition, which puts the whole experiment at the mercy of the hard drive. I am now trying to rework the code so that the host takes care of logging, so that my time-critical loops don't have to wait.
I am currently using LabVIEW 8.5
I have two questions:
First, how can I programmatically call the data-logging subvi on the host so that it runs in parallel with the main vi which runs the experiment and collects data on the real-time? I have attached the test code that I have been working with to figure this out, but it does not run the logging vi continuously in the background. I am aware that there is better functionality for this in newer versions of LabVIEW, but I would prefer not to upgrade unless there is no other option. I would like to be able to run my data-generating vi and have it start the data logging remotely.
Second, is there a way in the host VI to read values off the network variable using an event structure rather than polling it for updates?
Any help would be sincerely appreciated!
