Feeder Devices
In the sample configuration in Figure 4-1, data transmitted from the feeder devices can
be processed in the sub-station control device SICAM SC, displayed at the operating
and observation station SICAM WinCC, and transferred by the remote terminal unit
interfaces (via the network channels) to network control centres (SCADA).
In the case when commands are sent to the devices, equally flexible processing is
possible; that is, substation switching operations can be initiated from the network
control centres, as well as from the operation and observation unit of the substation
control system.
