Real-time highlights during a live event

Hi,
is there some documentation about this function? I want to create a live streaming player with real time higlights (manually inserted). The streaming is HDS through Akamai CDN with DVR.
Thanks!

Ben,
I was notified by SAP that this was corrected in DS14.1 SP3 Patch1 and DS14.2 SP1 Patch3. Reference SAP Note 1997294 (Data Services WSDL error: Unable to create WSDL for service).
The cause and resolution are as follows:
Cause:
This is regression. The parser that creates the WSDL entry will look for ACTA_INCLUDE_<path name to schema>; not ACTA_INCLUDE_1<path….>. ACTA_INCLUDE_1 blocks the path to the schema.
Resolution:
Workaround:
1. Export the rt job to atl.
2. Search for ACTA_INCLUDE_1.
3. Replace with ACTA_INCLUDE_.
4. Re-import the atl into designer, make no changes.
5. Create service and add the Web service.

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!

VI server
Mark the target VI as served on the machine on which it will execute and use VI server Call by reference to invoke the served VI.
This used to be taught as THE way to communicate syncronously with an RT app.

Possible to bypass tape and capture live events in FCP via Firewire?

I was thinking to buy a Canon XH-A1E or similar HDV camera. I was wondering if it is possible to run a firewire from the camera during a live event to a laptop running FCP in capture mode and capture the footage to FCP as it is being shot.
Thanks.

If the computer crashed, I believe you would lose the file currently being captured into. In much the same way as if you were to prematurely stop a copy process from one disk to another, it would simply disappear.
At any rate, if the file did survive it would most likely be unusable because the directory entry would be incomplete.

VI containing Event Structure will not receive front panel events in LabVIEW Real-Time.

Hi again, I'm working in my first UI (attached VI).
It works when running directly from PC. It doesn't when running from cRIO, there's the message "VI containing Event Structure will not receive front panel events in LabVIEW Real-Time". I've been reading and I found that "Event structures on RT targets do not support events associated with user interface objects, such as VI panels or controls. For example, associating the Value Change event with a control does not work. RT targets support only user events".
Is that the problem? If it is, how can I create Mouse Up, Mouse Enter, Value Change (or other user interface events) user events?
If I run my VI in FPGA mode should it run?

These standby redo log file groups can contain either of thread 1 or thread2, Multiple threads are used in RAC environment.
In general architecture, Once if any log switch (or) redo log is full then these will be dumped into archive log files, then it will assigned to new redo log files. Here in primary redo log file, you can see the status as Current, Active, Inactive so on.
During real time apply, whenever data written into primary redo log files, At the same time log writer will be active and that will be assigned to the one of the redo log file..not redo log file, you have to say standby redo log in standby database.
here unassigned means, this standby redo log file, can be used for next time, might earlier status as "active". Whenever standby redo log file is active then only DBID you can see.
If its in unassigned it will be idle, again if any new allocation then these will become active. its like chain/loop. It is very much normal behaviour.
UNASSIGNED - Online redo log has never been written to. This is the state of a redo log that was just added, or just after a RESETLOGS when it is not the current redo log.
ACTIVE - Log is active but is not the current log. It is needed for failure recovery. It may be in use for block recovery. It may or may not be archived.

Can you use event case with labview real time?

I have a real time application I am putting together and until recentally have concentrated on getting the data acquisition working as expected.
I am using a PXI-8183 in a 1031 chassis.
I am now trying to add the functionality for setting up the system in the form of a GUI remote front panel that I connect to with a host laptop. I am connecting with the host as expected and it seems to be working well in that respect.
My problem is with event cases, operating in a while loop on the target. They just dont seem to want to trigger when i click on a button I have set an event for.
I have looked through the documentation and cant see any reference to issues with event cases on rt, but I feel I am missing something fundamental. Can anyone help?

Barry

Does anyone know a work around to broadcast live (in real time) via video stream through a BC website?

Does anyone know a work around to broadcast live (in real time) via video stream through a BC website?
~Leritha

There is no work around. You would look to use a service, like Twitch, you get a embed code for the live stream, you put that on a page and away you go. All depends on the service your using.

Agent Real Time Status Events

In my environment we are having a Avaya definity setup having a AES and CMS setup.
ICM receives real time Agent Status from CMS and Call status report from AES.
Whenever I check the Agent status in Procmon PIM I can see the realtime agent status.
However when I check the PIM logs I see the HashIn records and setLogOn records every 10 seconds interval.
In CTI we receive the Agent State Event every 10 seconds.
My question is which events from AES/CMS update the realtime status to ICM.
The updates that I see HashIn/SetLogOn/AgentState events is it dependent on CMSRefreshRate as its set to 10 seconds.
Thanks
Alok

Is this happening to multiple agents or just one?

Presenter View During Live Events In Show and Share

Hi,
I am a bit confused about the user authorisation during live events of Show and Share. There is a user who is creating the event and publishing it. I think this user should be the moderator. He can see the questions tab and check the questions coming from the other participants and send them to the presenter view tab.
I have found some information about the moderator and presenter in the user guide for show and share but I could not find out which user can be a presenter, or are the presenter and the moderator the same user or not.
Below is from user guide:
The live event moderator pre-screens these incoming questions and comments as they arrive. Moderators can:
• Move any high-priority questions to the Presenter’s View tab. • Move any low-priority questions to the Removed Questions tab, either manually or automatically by keyword. • Use keyword filters to see and manage only the messages that match those keywords.
. The presenter then responds to any number of these pre-screened questions and comments. (These are messages that the moderator moved to the Presenter’s View tab.)
From the above information, it seems that there are seperate presenter and moderator, but is there a way to assign a user other than moderator only the presenter rights?

Great question, Ken! I too would like to know if there is a way to transfer video content management to an other author. In the case that a user publishes content and later leaves the company, retaining control of the published material is a requirement.

Event Structure in Timed Loop in real time cannot work

I am a new user for LabVIEW. And I met a problem which really frastre me!!! Hope someone can help me out. Thanks in advance!
I simply want to use event structure under timed loop, which is extrmely important in my design.
However, this works very good in my computer (without connect to FPGA).
Once I connect it to FPGA, then I can run it still but there is no response!
My file is attached. Please somebody helps me!
Looking forward to your answers!
Solved!

Test for Timed Loop.vi ‏9 KB

The FPGA runs headless. Event structures are not going to work. What you need to do is have an application on your host where the user presses a button, changes a value, etc. That event should send a message via TCP/IP to the code running in the real time environment. Then the real time environment should set a control on the FPGA to the value you want.
In general, real time programming with FPGA has multiple layers.
1) Host code-> handles user interactions and communicates them to real time code via TCP,UDP, etc. Displays data to user sent from the RT controller.
2) Real time code->runs headlessly. Handles messages from Host code, processes FPGA data, communicates with FPGA much like the host code communicates with the real time code
3) FPGA -> does acquistion and passes it via FIFO to the RT
The first thing you need to do is understand the architecture and how all these pieces of the puzzle work together before throwing things down on a diagram.

Not able to run Real Time Report(Live report)

Hi all,
I am working on a report which need to be run on real time, i am facing difficulty while running it at my end(India),
getting error as View Display Error whereas my counterpart in United States running at her end getting the result easly,
server is located at United States,we share the same internet speed,I tried different means by putting appropriate filter
in order to reduce the data size but still couldnt see any result. Can anyone please suggest me what is the issue
and what need to be done in order to get the results for real time report faster at my end.
Thanks for help.

A couple of suggestions.
First, make sure you are reproducing the report conditions as well as the user access settings. Different user access can make a big difference in report performance.
Second, enter an SR with Oracle support. They may be able to help troubleshoot connection issues.
When we see dramatically different response times in different locations, this usuallly means a network issue. It may not be in your corporate network, but somewhere between you and the data center.

Real time queries to know more about live project

Hi All,
I am new to XI, I have some doubts about real time xi project related activities.
1. Who will be responsible for preparing the minutes of meeting? (XI Developer/Team Lead/senior consultant etc)
2 In usual Dev->QA->Prod project cycle...
Where would the Configuration and Version Control come into picture?
Who is responsible for configuration process of the developed objects?
How the configuration process would be in real time XI project? Are we needed to use any external configuration/version control tools like VSS etc..?
3. I come across the terms like Legacy Systems, Third Party systems, SAP systems, Non-SAP systems, Web Systems.
In real time project, can you please answer with few names for each type of systems above I had mentioned? I know this depends on landscape of the project. But I would like to know how the names of these systems would be in real time.
Like .. for Legacy systems --> Mainframe/AS-400 etc (Pls correct me,if i am wrong).
These questions could be very basic questions for Experts. Please answer these questions.
Thanks in advance.

Hi,
<i>1. Who will be responsible for preparing the minutes of meeting? (XI Developer/Team Lead/senior consultant etc)</i>
In general , TL will prepare and rest of all seniors will approved/ signed if it is senior level meeting , Offcourse it depends upon the meeting .
<i>2 In usual Dev->QA->Prod project cycle...

Yes Configuration will be the developer or the senior for interface configuration / basis for SLD configuration
the respective will be the responsible
<i>3. I come across the terms like Legacy Systems, Third Party systems, SAP systems, Non-SAP systems, Web Systems.</i>
It depens upon the project ... dont ask like this type questions .. these are very confidential ...
I hope this is technical forum ..

Initial Error during Real-time control

Hello all,
I am currently controlling a DC motor in real time by using an simple PI controller.
Unfortunately, I found that there is some initial error when the desired motor speed (which i desired) is zero, the error signal come from the actual DC motor is oscillating at -3.
What should i do in order to make the initial signal to zero?
Thank you very much.

Ok barp, i had work out for many scale (-0.1, 0.01, 0.1, 0, 1, 2, 10, 100, 500, 1000, 2000, 3000) and i will show you here. P/S: Red color= Actual motor speed, Green color= Setpoint(desired Speed), and the white color= controller signal.

How can I generate a real-time highchart from my database data?

I have looked several links; however, I couldn't find a working demo showing how to implement a highchart using data from a database.
Objective: I want to generate a real time highchart line graph getting data from my database. What I want is very similar to the
HighChart Demo which provides a real-time highchart with randomly generated values. It is also similar by X-axis and Y-axis, for I want my x-axis to be "Time" (I have a DateTime column in my database) and y-axis to be an integer (I have
a variable for that as well in my database).
Please I need help in sending the model data to my razor view.
Note that I am already using SignalR to display a realtime table. I also want to know if it can be used to automatically update the highchart as well.
Below is the code snippet of my script in the view. I have used the code provided in
HighChart Demo link for generating the highchart. Please tell me where should I apply the changes on my code.
