TCP/IP-based WAN media

•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

To permit redundant data transmission, outstations can be connected to the SIMATIC PCS 7 TeleControl center over two paths.
