Introduction
1.4Ethernet and Your Application
Careful planning of your network can help you achieve optimum performance. You should consider whether Ethernet meets the demands of your application, which devices are compatible with your network and how to minimize congestion on the network.
1.4.1Meeting the Demands of Your Application
The Quantum Ethernet web embedded server modules provide connectivity to many different systems via an Ethernet network. However, Ethernet installations have characteristics which may not be suitable for all control applications.
