Choosing a Telemetry Network
Overview
A telemetry network provides the communication pathway in a SCADA system.
Topologies, transmission modes, link media, and protocols make up a telemetry
network.
An application can have more than one telemetry network. In some critical
applications, you may want to design a back-up system or recovery procedure for
your main network. Analyze your requirements and select telemetry networks
accordingly.
Design the network by selecting each component.
