Telecontrol with a non-redundant master station (TCSB)
Figure 1-2
In the telecontrol applications of the example shown, SIMATIC S7 stations communicate with
a non-redundant telecontrol server (TCSB) in the master station.
● Telecontrol communication between stations and master station
The communication is via the following paths and communications modules:
– Communication via the Internet: S7-1200 with CP 1243-1
– Communication via the GSM network and the Internet: S7-1200 with CP 1242-7 or
The establishment of terminal connections with encryption is initiated automatically by the
telecontrol protocol used by the various communications modules.
The creation of VPN connections between the CP 1243-1 and telecontrol server is
optional.
The telecontrol server monitors the connections established by the remote stations.
● Inter-station communication
Stations of the same type, for example S7-1200 with CP 1243-1, can communicate with
each other by sending the frames via the telecontrol server.
