TCP/IP-based WAN media

•Special radio network optimized for Ethernet, e.g. with SCALANCE W industrial wireless LAN components

•SCALANCE X switches with optical ports and fiber-optic cables for distances up to 120 km

•Public network and Internet via DSL or GPRS

•Broadband system such as OTN, PCM30, etc.

To achieve redundant data transmission, it is also possible to connect an outstation via two transmission paths to the con- trol center in the SIMATIC PCS7 process control system or to a node station. It is irrelevant whether the two paths are of the same type or different, e.g. dedicated line with telephone net- work/ISDN and GPRS.
