Figure 3-15 SINAUT ST7cc / ST7sc control center system with TIM 4R-IE connected over Ethernet,
1 connection to IP-based WAN or LAN,
2 classic connections to WAN, for example over SINAUT MDx modems
Other modems with an RS-232 or RS-485 interface can be used instead of the SINAUT MDx
modems, for example wireless devices or the SINAUT GSM modem MD720-3. The RS-485
ports of the TIM 4R-IE also allow a star-shaped dedicated line network to be connected
using several modems. You will find more information on this topic in the section "Installation
and commissioning of a SINAUT modem".
Apart from the SINAUT ST7cc / ST7sc control center system, a local controller, for example
an S7-400 can also be connected to Ethernet and exchange data with the stations in the
telecontrol network. This controller could, for example, be used to display data received from
the stations on a panel or console or for emergency input by an operator if ST7cc / ST7sc
failed.
The controller could also handle central control tasks such as starting up the system.
SINAUT ST7cc / ST7sc and the central controller are then both supplied with parallel data.
Both can receive the same data or data specifically intended for one or the other. The
transfer of commands, setpoints, parameters etc. to the stations in the telecontrol network is
possible from both ST7cc / ST7sc and from the S7-400.
The next figure shows a similar configuration. Here, a redundant SINAUT ST7cc or ST7sc
control center system is connected over one of the Ethernet ports.
