Segregating
Traffic
The best method to protect Quantum Automation traffic from information s
stems
traffic is to provide a completel
separate ph
sical network for automation control.
Another method is to use readil
available Ethernet devices such as brid
es and
routers to lo
icall
se
ment the network, isolatin
office traffic from control data.
Minimizing
Delays
Components such as repeaters, brid
es, routers and hubs take a finite time to
process each messa
e. If messa
es pass throu
h man
of these devices,
processin
dela
s will accumulate. Dela
times are available from device
manufacturers. Check with
our network administrator to
uantif
the effect on
control messa
es and to determine whether it will be si
nificant for
our
application.
Using Switches
Ethernet switches can be used to ensure hi
her network performance. These
newer devices allow each connection to have access to the full 10 Mbps bandwith
instead of havin
to share the bandwith with all other nodes. The
reduce the
timin
problems associated with Ethernet collisions and the resultin
“back off”
transmission dela
s. Check with
our network administrator to see if
our
application would benefit from switchin
Ethernet devices.
