[etherlab-users] UDP communication in Etherlab? Would it be fesasible?

[Julian Stoev / Юлиан Стоев]

Hello,

We are quite happy how our Etherlab setup works now. We are thinking
about using it on longer term for our work, not only as development,
but also as deployment platform.

There is however one question, which was formulated recently - how we
can communicate with other real-time systems, for example LabView.
Part of our algorithms (visual) works in LabView. The result is a
sequence of real numbers with sampling rate approximately 100Hz. We
know it would be quite possible to use real-time UDP on a dedicated
cable to make this data exchange fast and deterministic.  LabView is
capable to output data on UDP, so it is OK from that point. But we
have no means to read it from Etherlab now. This would be possible for
example in RTAILab, as far, as I know, but we would not have Ethercat
capabilities, which is important for us.

I guess I gave sufficient background on this, so the main question
would be obvious probably. What wold be the easiest way to include
deterministic UDP input stream in Etherlab. What would be the effort
complexity? I am control engineer, not a Linux specialist and we would
prefer to have some expert opinion on this before scheduling efforts
on this.
Hopefully we will be able to provide this back to the community,
depending on our management.

Any opinion on this?
