1.4 Ethernet and Your Application
Careful plannin
of
our network can help
ou achieve optimum performance. You
should consider whether Ethernet meets the demands of
our application, which
devices are compatible with
our network and how to minimize con
estion on the
network.
1.4.1 Meeting the Demands of Your Application
The Quantum Ethernet web embedded server modules provide connectivit
to

have characteristics which ma
not be suitable for all control applications.
