Real time communication protocal

[yifeng.li]

Hi all,

I am using compactRIO 9022 and 9024. I need to have real time communication with the central controller.

I am wondering is there any real time communication protocals are available for use or we have to develop by our own.

Best regards,

Yifeng.

Are you after this sort of information: http://www.ni.com/white-paper/4720/

That seems relevant to my project. But is there any tutorials to demonstrate how to use it? I can't find any.

It is a built in communication for LabView. I am not sure whether is compactable with the controller in the field.

Yifeng,

There are a few options that you have as far as tutorials are concerned.  Here is a link to an introduction video:

For the last 5 minutes of the video, it provides a thorough explanation of the basics of Real-Time.  Beyond that, there is a Getting Started with the LabVIEW Real-Time Module Guide that you can utilize to set up your project and learn some basic programming skills.  It can be found here:

Hopefully these are a few resources that can get you started.  You will find that programming something to a Real-Time target is very similar to just regularly writing code in LabVIEW as far as the majority of structures are concerned.  If you need any further help with those basics, I would suggest looking at standard LabVIEW tutorials.
