Real-Time Sequencer Feedback and Questions

Post your questions and feedback to the Real-Time Sequencer Architecture and Real-Time Sequencer Architecture Example here.
Brian K.

I just purchased the USB 6341 DAQ card. I am using Dev1/.Port1 to control 4 driver transistors. The transistors fire 4 SSR. I am trying to create a sequence for the 4 transistors. Sometimes a test unit that is driven by a SSR will fail. So I have to change the sequence for the failed DUT.
Basically each SSR will be ON for 6 seconds. There will be a delay of about 5.75 seconds for the next valve to fire. The delay is used to balance the pressure testing. The second valve will need to start at 5.75 seconds later. Basically the two valves must cross at the 50 % turn OFF. How can I perform this task. There are at least 7 different test sequences??
Thanks,
Philip

Is vision development module in labview 8.6. sufficient for real-time image acquisition and analysis using a webcam

Hi,
I'm new to labview and trying to develop an eye-tracker using labview 8.6. It has the vision development module and i was wondering if this was sufficient for real-time image acquisition and processing or would i be needing any other software tools.
Solved!
Go to Solution.

Hello, certainly it is possible and sufficient for real-time tracking!
About eye tracking - if you need an example, you can find the code here:
https://decibel.ni.com/content/blogs/kl3m3n/2013/10/08/real-time-face-and-eye-detection-in-labview-u...
The code uses OpenCV functionalities along with the LabView UI (and some other functions like overlay).
Hope this helps a bit.
Best regards,

I want to be able to tweak the graphic equalizer in real time while recording - and have this have the audible effect written to the recording. At the moment i have to go into post-production and manually set the graph equalizer at various time points .

This won't be real-time as you record, but you could tweak the EQ in real-time after the recording thus:
Record what you want to tweak into GB with no effects.
Solo the track and output it into something like Audacity.
Start Audacity recording, then play your track in GB as you make those tweaks. That's what Audacity will record.
Get that file from Audacity and put it into GB, then you'll have that effect.
Sorry if it's complicated, but that's what came to mind. Hope it works.

Any real time complex validations and assignments

SIT Real-time data logging and passing data

Hello all,
I am pretty new to LabView real-time, so I just want to confirm a few things. I am also using the Simulation Interface Toolkit.
Let's take the Sinewave.vi from the SIT examples. I have modified it to use sinewave.dll, and run on PXI-8101. If my understanding is correct, when I click "Play", the entire Sinewave.vi is deloyed into PXI-8101, and therefore the entire VI is running at the same pace. The front panel I see on my desktop is slower snapshots of what is actually happening?
1) Let's pretend now that the sinewave model is time critical and must run every 10ms. How do I do that? I have noticed that within the "SIT_Indicator_Indices" loop, there is a Wait 50ms block. Is that accurate?
2) I have also added a time elapsed block that will change the Frequency and Amplitude inputs as a function of time. I made them update every 2ms. What clock are we running on? If my sinewave.mdl suddenly calculate integration (time dependent), can I use that elapsed time block as my timer to pass into the model?
3) How fast is the sinewave.vi running anyways?
4) Let's say I want a log of the sinewave output (a data point every 10ms). I don't need the log in real-time, I just want to do some analysis on it later. How do I do it?
Thanks.

Sine Wave.vi ‏104 KB

Hi Bladhart,
When running the in the Development Environment (pressing the run button on the Real-Time vi) there will be an extra thread to handle the front panel you see. This thread will be handled just like any other thread in Real-Time and will take processor time, thus slowing down your entire application to a certain extent.
1. You would need to make sure everthing inside the loop can execute within 10ms and change the wait time to 10ms. Or you can use a timed loop set to run every 10ms and get rid of the wait time but again you would need to ensure everything in the loop can execute in under 10ms.
2. The elapsed time should be running off the Real-Time system clock.
3. The time that the Sinewave.vi is running is system dependent, there is no set speed.
4. You can log the data by saving to a *.tdms file. You can then use the data from the *.tdms file to do processing later.

Real-Time Enabled field and Generic extarctor

Hey,
We are using PI 2004_1_470 on our R/3 system, and I just noticed that there is a field called Real-Time Enabled on the generic delta screen. This maps to ROOSOURCE-REALTIME.
What is the field being used is? Is this some early release of the near real time function that will be part of BW 7.0, or can I use this with BW 3.5?
Thanks Bill!

Hi Mickey,
in general:
1.) you need a 7.0 DataSource (3.X DataSources cannot deliver Real-Time information)
2.) you can only run a DataSource in one mode, either "Real-Time Data Acquistion" or "Standard", i.e. the same DataSource cannot be incorporated in the data flow in different modes.
3.) Business Content DataSources are not delivered with the option "Real-Time Data Acquistion" at the current point in time. We are currently discussing which DataSources should be made available to start off with.
If you have specific scenario in mind, please contact your Ramp-Up Coach in order to direct support by us.

Real Time DAEMON Stops and gets inactivated.

Hi,
We have real time DAEMON loading the data from delta queue to the ODS.
It becomes inactive after some time with lots of error messages. Don't understand what they mean . How to get documation to understand what the problem is and how to activate them again ?.
Also, I have another DAEMON, which gets to STOP condition. It doesn't start again even if I try to "Start" it in RSCRT transaction. How to start it again ?. It also gives error messages.
Thanks.

Hi,
Daemon is inactive when no batch job runs for this daemon and no upload via the assigned InfoPackages.
Daemon starts after it has a free batch job and currently no upload with the assigned InfoPackages.
Daemon is stopped when the started data transfers are completed and all related requests are closed.
hope it helps....

Real-time PID control and continuous buffered acquisition. Does it work together?

I use the "real-time PID control.vi" that acquires single AI point and generate single AO point in every "while loop" iteration to control a piezo actuator motion. Simultaneously I need to do (in another loop) a continuous buffered acquisition of another two AI channels (in the same rate as first AI channel).
It does not work together.
Does anybody know how to fix it?
Platform: LabVIEW 6.1
Board: PCI-6024E

Hi,
I would try to avoid the idea of using a separate loop since the PID
loop is a continuous acquisition and will require un-interrupted access
to the Analog DAQ system of the board. The last thing it needs is for
you to attempt to start other AI functions at the same time.
Configure your AI in the PID loop to read in multiple channels (Just add
some more channels to the Input Channels Control. Separate the data as
it comes out of the AI single Scan function using Index Array or other
Array functions into that needed for the PID and that needed for your
other data (the example is already doing this to make sure it only gets
1 channel of data into the PID). If you don't need to sample all your
channels of data all the time you can throw some data away as
required.
Obviously your other channels are now arriving one sample at a time so
if you might need to build an array, insert into an array or use Auto
Index on the loop if you are data logging.

Dave R.

VI on LabVIEW real-time is loading and running a DLL which has been deleted from the machine

OK, this is a weird one (at least, to me :-) )
I have a small real-time demo application VI that I am writing, using some new VIs I just created. My new VIs are wrapper functions for a DLL, using Call Library Function Nodes.
In the process of debugging, I decided to delete the DLL and run without it, to confirm that I am actually loading and using the DLL (since it seemed to have stopped doing something it had successfully done just a little while earlier).
The VIs that use that DLL still run, and at least some of them actually do what they are supposed to do. But the DLL does not exist on the real time machine! Not only did I delete it, reboot the machine, and check that it was gone, but through my ftp program I searched the whole hard drive for that DLL and did not find it (the search succeeded in finding a different DLL which did exist on the system, so the search-via-ftp is working).
How could this happen? What am I missing? Could this somehow be the result of a corrupted VI or is there some more logical explanation for the phenomenon?
Thank you.
Batya

Nathan is right at least for the Phrlap ETS based RT systems. For VxWorks you have to (or maybe used to have) to download the shared library to the controller before you could deploy an executable that makes use of them. For Pharlap ETS systems if you deploy a VI library dynamically to a machine it will download everything including shared libraries to the the RT target memory and run it from there. Only if you create an executabel and "install" it to the target and run it from there will it use whatever VIs are in the executable and also use the shared libraries that have been installed onto that system (at least for Pharlap ETS RT targets. As mentioned before for VxWorks targets, the deploy process even for executable installation did for some reasons not take care about moving the according *.out library to the target together with the rtexe).

Real time fan speed and temperature of the Thunderbolt Display

Is there software program that allows you to know the real time speed of the itnernal fan of the Thunderbolt display. Also I would like to monitor the internal temp of the TBD. I have Istat which allows me to do both but only for my MBPro not my montior.
Thanks.

Have you ever cleaned you machine? Since it's an iSight (which is actually 3rd generation, Ambient Light is the 2nd, Rev A the 1st), you can't open it but you can vacuum the air vents, which might help.

Some kernel updates (I386 on my case), and my first question is: "How do I update this? Is it safe to be the first thing to be done?" Is it only copy to the Run directory (usr\sap\<SID>\SYS\exe\run)?
Also a component BC-FES-IGS has some updates, but I don't know what is this and how to update. (it says: Installation for SAP IGS integrated in SAP Kernel igsexe_16-10003071.sar)
All the rest (SAPK* files), seems to be normal patches that is possible to use spam to update them. Correct?
How to use SPAM/SAINT? What is used in one time, and on others? Do they do the same?

Hi Pedro,
Some kernel updates (I386 on my case), and my first question is: "How do I update this? Is it safe to be the first thing to be done?" Is it only copy to the Run directory (usr\sap\<SID>\SYS\exe\run)?
As SolMan is a dual stack machine, you can use JSPM to update the kernel. Another way is to extract the Kernel SAR files into the exe\run directory. It is a best practice to update the kernel before the support packages. Take a backup of the existing exe directories before you update the kernel and also pay good attention while downloading the kernel. you need to take care while choosing the correct version of the kernel (either 32 bit or 64 bit and ITANIUM or XEON). If you choose the wrong kernel, then ur SAP system will not come up.
Also a component BC-FES-IGS has some updates, but I don't know what is this and how to update. (it says: Installation for SAP IGS integrated in SAP Kernel igsexe_16-10003071.sar)
Extract the IGS SAR also along with teh kernel files.
All the rest (SAPK* files), seems to be normal patches that is possible to use spam to update them. Correct?
Yes!!! You may have to update the latest SPAM/SAINT (SAPKD700*) before updating the SP's.
How to use SPAM/SAINT? What is used in one time, and on others? Do they do the same?
Support Packs can be updated using SPAM and the add-on upgrades has to be done using SAINT.

Forums Updates: feedback and questions answered

Some of you will have noticed some forum downtime today and no doubt you have noticed the changes!
I would appreciate it if people would consider the current state of the forum as a release candidate, rather than a final release. I am sure there are some things that will need tweaking or fixing and some unforseen problems/issues.
Please report any such problems on the Forum, Wiki and Documentation Discussion board. You can also provide feedback there.
A word of caution - when you click on the RSS link in the top right it will take you to the topics_anywhere page. While viewing this page the navigation area in the top right will show that you are no longer logged in but you are! Please do not panic.
Thanks.
.:edit:.
If people are confused by some of the recent changes then PLEASE feel free to ask questions in this thread. Several of the boards have been moved or removed and we need to make sure everyone still feels that there is a proper place to post everything

I suppose that the one who added the new setting in user profile could answer this question better.
Anyway, I do not have any experience with writting php, but something like:
<select name="postorder">
<option value="asc" <?if(user wantsOldestFirst) echo "selected=true"?>>Oldest First</option>
<option value="desc" <?if(user wantsOldestFirst) echo "selected=true"?>>Newest First</option>
</select>
Please remember that I do not have php skills, so if I wrote something enormously stupid don't blame me, blame the .... keyboard.

HT1553 What is the best system for a real time cloud back up of documents? My MacBook crashed, and I lost 2 hours of writing and could not find a way to restore it.

My MacBook Pro crashed while I was rewriting a book, lost more than an hour of work and could not find a way to restore it. Did not have Time Machine set up, but it appears that Time Machine does not have Real Time back up and documents must be manually stored.
I need an automatic, real time back up to keep this from happening - I'm not happy my MacBook has crashed twice now. What is the best cloud system for Real Time backup? Thanks to anyone who can help me, I'm not the most astutde computer guy... James

One way would be to use Dropbox, or a similar sync service, and just keep your critical documents in the appropriate folder. Dropbox, at least, keeps a local copy of everything and syncs automatically to the cloud whenver a change is made. Dropbox is free for up to 2GB of data.
There are also true backup services such as CrashPlan+:
http://www.crashplan.com/consumer/crashplan-plus.html
which provide automatic backups whenver a change is detected. It's not free, but usually such services aren't too expensive unless you need to back up a lot of data.

How to replicate data between Oracle db and SQL server dbs in real time?

Hello,
Anyone has idea that what tool we can use to do data replication in real time between Oracle and SQL sever or Oracle and Sybase or Sql server and Sybase?
This is topic is brought by a project manager?
I only know Oracle to Oracle dbs by streams or GoldenGate.
Thanks
Jerry

Since GoldenGate's bread and butter was (and is) replicating data between heterogeneous data sources, and since Oracle has purchased GoldenGate, that would seem like a natural place to start.
Beyond that, it depends on the architecture you want and how you define "real time." Just about any ETL tool on the market, whether Oracle's ODI or OWB or any number of third party products (Informatica, DataStage, etc) can handle "trickle feeds" from various data sources to a database target of your choosing. Different tools will have different sorts of integration with the source database, many will require that a bunch of triggers are created to track changes on the source systems.
If you want Oracle to control the replication process (which doesn't really make sense if we're talking about replication from a non-Oracle database to another non-Oracle database), you can use the Oracle Transparent Gateway products to create database links from Oracle to the non-Oracle databases and query data on the source database periodically.
