F.2 SICAM CMIC as Telecontrol Substation with Node Func-
tion (Protocol Converter)
Features:
• Communication with the control system via IEC 60870-104
(Ethernet-Interface, X1 or X4, can be set with parameter)
• Communication with the protective devices via IEC 61850
(Ethernet-Interface, X1 or X4, can be set with parameter)

─ Data exchange between subnets only via SICAM CMIC application function
• 1 default router
• Parameter Network settings | IP adress | Mode of Ethernet Ports = 2 IP
addresses (independent ports)
Both ethernet-Interfaces (X1, X4) have the same MAC-address
