The SIPLUS RIC bundles usually comprise:

CPU

Interface/communication module (if necessary)

Memory card

CD with library and registration code.

SIPLUS RIC products require additional material to establish telecommunication links, e.g. TCP/IP converters – serial, dedicated line modems, media converters, TCP/IP routers, SCALANCE S612 and S613 security modules, switches, cables etc.

In order to implement telecontrol networks, basic topologies including point-to-point, multi-point, star and ring can be con- figured using classic or TCP/IP-based media. These can be combined flexibly independent from existing infrastructure.

Classic WAN media

(IEC 870-5-101 telecontrol protocol)

Dedicated line via modem, e.g. SINAUT MD2

Dedicated line over fiber-optic cables

Private wireless networks

TCP/IP-based WAN media

(IEC 870-5-104 telecontrol protocol)

Ethernet networks, e.g. SCALANCE X with fiber-optic cables

Industrial Wireless LAN with SCALANCE W

Public networks and the Internet using DSL and/or GPRS

Satellite communication, e.g. with Inmarsat

RTU S7-400
