SINAUT ST7 - example of redundant telecontrol connections (point-to-point topology)

G_PCS7_XX_00266

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.
