Yusuf,
What do you mean by time critical ? Is your network localized? What I'm
getting at is this -- depending on what your data rates are and how your
data communication is set up you may have no problems using the non-realtime
networking.
My personal expericence is that We have 8 embedded CPUs with 100BaseTX
ethernet and 5 other computers needing data from the 8 embedded CPUs. And
the 100BaseTX is fine, a human can't tell the difference. For the small
amount of really time critical data (6 bytes from each of the 8 embedded
CPUs every 30 Hz), I'm setting up an RS485 net and scheme.
