Connecting telecontrol substations to the telecontrol center using SCALANCE M routers

Application example for SCALANCE M826-2

The application examples given here show a typical telecontrol application with Telecontrol Professional, consisting of a telecontrol center with ST7cc/ST7sc. A TIM 4R-IE is connected via one of its two Ethernet interfaces with the control center PC (e.g. ST7cc). SINAUT stations are connected over the second Ethernet port of the TIM using the SCALANCE M826-2 over SHDSL two-wire lines.

It is possible to operate up to 30 SINAUT dedicated line modems on this port. If the stations in this network have to be provided with the date and time, the control center PC assumes the function of the clock-time master. The TIM 4R-IE is regularly synchronized by the PC via the Ethernet connection. It then takes over the synchronization of the connected stations.
