Application and properties
Properties of the CP
Application
The CP is intended for operation in an S7-1200 automation system. The CP allows
connection of the S7-1200 to Industrial Ethernet or via the Internet to a control center with
TELECONTROL SERVER BASIC (TCSB version V3).
With the combination of different security functions such as firewall and protocols for data
encryption, the CP protects the station and even entire automation cells from unauthorized
access and protects the communication between the remote S7 station and the master
station (TCSB) from espionage and manipulation.
Communications services
Communications services
The following communications services are supported:
●
Telecontrol communication
The CP is a communications processor of the SIMATIC S7-1200 for system connection to
control centers with the OPC server application TCSB.
The communications protocol used allows IP-based data transmission for telecontrol
applications. As an integrated (unconfigurable) Security function, the telecontrol protocol
encrypts the data for transfer between the CP and telecontrol server.
For a description of the configurable Security functions, refer to the section Industrial
Ethernet Security (Page 13).
●
S7 communication and PG/OP communication with the following functions:
– PUT/GET as client and server for data exchange with remote stations (S7-
300/400/1200/1500)
– PG functions
– Operator control and monitoring functions (HMI)
