[RTnet-users] TDMA cycle times

[Bernhard P. <ber...@ch...>]

All,

I know this is an often discussed topic and I'm sorry to bother you
again with it.

Has anyone achieved TDMA cycles below 200us so far? Is short, I need to
serve 8 slaves within 165us (~6kHz) and I was wondering if it's possible
using RTnet. The amount of data is very small, let's say 16bits per slot
(what a waste using GBit Ethernet ;) but, it's got to be _fast_

Those also reading the RTAI list might have seen my latency/jitter
benchmarking with a very powerful Core 2 Quadcore machine. This machine
shall serve as the RTnet master, equipped with an Intel Pro/1000 NIC for
RT communication.

Jan once mentioned freqs somewhere below 10kHz should be possible using
a decent machine. well... is it doable?

Any hint appreciated!
