Event in sbRIO

[Himanshu_Goyal]

Dear All,

           Event structure is not working in sbRIO 9601. So instant of this what type of method i use to fire a event in sbRIO.

Thanks and Regards

What kind of events are you trying to use?

From the LabVIEW help:

---

The following details apply when you use this object in an RT target VI.

RT targets support the Event Structure only with dynamic events.

---

So anything else but a dynamic event will not work on your sbRIO.

Dear

         Here i am trying to fire a event on a butten click..

As swenp stated, only dynamic events are supported in LabVIEW RT. 

RT applications do not natively run a user interface, so many of the features of a user interface, like mouse and value change events and many property nodes, are not available in LabVIEW RT.  Ideally, your user interface could run in a host environment like Windows and pass the user interface events to Single-Board RIO via shared variables or TCP/IP.  Another alternative if you must run the UI in "interactive" mode on the RT target, you could poll for the user interface changes, but that will consume CPU cycles.

Hi Spex,

Nice to find you...

I am also working on a sbRIO-9601 based application. We are running very heavy application on sbRIO. We implemented every possible RAM saving techniques.

After deployment of complete code on sbRIO only 5%(6Mb) of RAM is available free. This causes sbRIO in hanged condition.

Please suggest me some concrete solution for memory management in sbRIO. Possibly we are using modern code designing techniques.

We need extra ram while processing. We cannot move to higher version of sbRIO.

One more thing, I installed/need following programs on RT:

LabVIEW Real-Time 9.0

Language Support for LabVIEW RT 1.0.0.3

NI-RIO 3.2.0

NI-Serial RT 3.3.4

NI-VISA 4.5.1

NI-VISA Server 4.5.1

Network Variable Engine 1.6.0

Variable Client Support for LabVIEW RT 1.6.0

Hi Deepak,

Sorry for the delay in response.  I traditionally only browse the discussion forums for Single-Board RIO questions when I have some free time from my main job as Product Manager.  Also, this question probably would have received more response if it was created as a new thread in the Real-Time Measurement and Control board. 

Your question is complex and has no simple answer.  There are many ways to optimize LabVIEW code and memory footprint on a Real-Time system.  Even with all optimizations, there are situations where an application must trade-off features to fit in the allowed memory, or upgrade to a controller that can support the desired feature set. 

For general support and ideas for optimizing your application, I would provide as many details as your are comfortable with about your application in the discussion forums and see what the RT experts in the community recommend.  Its very likely that one-on-one support from NI Technical Support would help you out as well, especially if they are able to see your code, your architecture, and how you are managing data. You can get contact information for your local support resources at http://www.ni.com/support/

I wish you the best in resolving this memory issue, and feel free to let me know if you are not able to get into contact with adequate support resources.

Regards,
