SINAUT ST7 telecontrol protocol 17
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.
