Introduction to the SINAUT ST7 system

1.1
Area of application
Process control over WAN and Ethernet
SINAUT
®
ST7 is a system based on SIMATIC
®
S7 for fully automatic monitoring and control
of process stations that exchange data with another and with one or more control centers
over a WAN (wide area network) or Ethernet (TCP/IP).
The control center
The following can currently be used as control centers:
●
SIMATIC controllers S7-300 or S7-400. This solution is suitable for less complex control
centers, in which only a current image of the process data in the stations is required. By
entering commands, setpoints or parameters, it is possible to intervene in the process
control of the stations.
●
SINAUT ST7cc, the PC control center (single or redundant) based on WinCC. This is a
control center system for SINAUT ST7 specially tailored to the event-driven and time-
stamped data transmission of the SINAUT system.
●
SINAUT ST7sc, the link to control centers of other vendors over OPC. Using the "Data
Access Interface", the SINAUT telecontrol technology can also interface with the control
center systems of other vendors. ST7sc has extensive buffer mechanisms that prevent
data loss, for example, if the OPC client fails.
The SINAUT WAN networks
The following WANs can be used for data transmission:
●
Dedicated lines (copper or fiber-optic cables)
●
Private wireless networks (optionally with time slots)
●
Analog telephone network
●
Digital ISDN network
●
Mobile wireless networks (GSM)
All networks can be combined as necessary. Redundant paths are also possible. Star, bus
(linear) and node structures can be implemented.
SINAUT over Ethernet
SINAUT communication is possible between station and control center and between stations
over Ethernet or IP-based networks. This includes transmission using the GPRS service in
mobile wireless networks (GSM networks). The prerequisite is continually available
connections.
