Inter-Station Communication between S7-1200 Stations Using TCSB V3.1 via CP 1242-7 V2

  • Entry
  • Associated product(s)
An automation infrastructure contains S7-1200 substations that are to exchange data in a cost-effective way on a wireless basis.

The infrastructure of a sewage treatment plant contains two S7-1200 substations. TeleControl Server Basic V3.1 in the master station allows inter-station communication between the two substations. The TCSB V3.1’s counterpart is the CP 1242-7 V2 included in each substation. Communication takes place via the cellular network and the Internet.

The following functions are implemented in this application example:

  • The “Inspection Shaft” station (Station 1) cyclically requests data from the “Stormwater Overflow” station (Station 2).
  • The “Stormwater Overflow” station sends data to the “Inspection Shaft” station on an “event-triggered” basis.
  • The master station monitors the status of the connected substations.



  • TeleControl Server Basic V3.1 enables economic data communication between the remote stations.
  • GPRS and Internet: Always-on functionality.
  • In the event of a connection failure, the CPs buffer the data; when the connection is restored, they transfer the aggregated data to the TeleControl Server.
