Application and properties

1.1

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 the following control
center systems:
● Telecontrol server (OPC server application TCSB V3)
● DNP3 master station
● IEC master station
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 attachment
to the control center systems named above. The CP can communicate with redundant
control systems.
For each control center system the relevant telecontrol protocol is activated on the CP
("Type of communication"). The protocols allow IP-based data transmission for telecontrol
applications.
You will find the usable security functions in the section Security functions (Page 13).
● Messages / e-mail
