Communications services

The CP is intended for use in an industrial environment. The following applications are
supported by the CP:
Telecontrol communication
The following applications are possible if telecontrol communication is enabled in the
configuration of the CP.
● Communication with a control center
Remote S7-1200 stations communicate via the mobile wireless network and the Internet
with a telecontrol server in the master station. The telecontrol server communicates with a
higher-level control system using the integrated OPC server function.
● Event-driven sending of messages using SMS or e-mail
Via the mobile wireless network, the CP sends SMS messages to mobile phones or e-
mails to PCs with an Internet connection.
Both types of messages are configured in telecontrol communication in STEP 7. The use
of program blocks is not necessary.
For information on the configuration, refer to sections E-mail configuration (Page 68) and
Messages (Page 100).
● Inter-station communication between S7-1200 stations via the telecontrol server
In this application, the CP establishes a connection to the telecontrol server via the
mobile wireless network. The telecontrol server forwards the messages to the destination
station.
For this communications service, the CP and TCSB use their own protocol on OSI layer 7
that among other things supports certain security functions, see section Security functions
(Page 16).
