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
