Hi All,
Well it looks like we are close to getting a realtime ethernet
capability.
Albeit at the raw socket level.
I would like to take advantage of this technology immediately and I was
wondering about what to
put in the data.
What I have in mind is some sort of self defining system where you can
have
elements each given a time slice to do their business within.
Just plug in a new guy and off you go.
Immediately I need to connect a small number of systems. Two or three
controllers and about 4 I/O subsystems.
The I/O subsystems are going to be diskless embedded 486 or pentium
PC104 units with some sort of
default alarm / monitoring capability.
Each unit will have approx 100 + Digital I/O points 16 x 16 bit diff
analog inputs and 16x 16 bit analog outputs. ( Subject to my being able
to pack it all in the box .)
The communications will be RT Ethernet 100Mhz.
There must be a number of excellent ways of solving the protocol problem
already worked out.
In fact defineing what to use here looks like an excellent Open Project.
Any suggestions ???
Regards
Phil Wilshire
