SINAUT ST7 telecontrol protocol

SINAUT ST7 - example of secure TCP/IP-based connection over Internet via DSL (star topology)

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

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.
