Application and properties

1.1

Properties of the CP

Application
The CP is intended for operation in a SIMATIC S7-1200 automation system. Der CP ist der
Kommunikationsprozessor zum Anschluss der S7-1200 über öffentliche oder private
Infrastrukturen an eine Telecontrol-Zentrale mit einer der folgenden Applikationen:
● SINAUT ST7cc
● SINAUT ST7sc
● SIMATIC PCS 7 / WinCC TC
● A SINAUT master station S7-300/400
● A SINAUT node station
For the telecontrol communication the CP uses the "SINAUT ST7" protocol.
You will find the supported transmission protocols and network types in the section
Communications services (Page 11).
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 from espionage and manipulation.
Expansion of existing SINAUT systems
In existing SINAUT systems with SIMATIC stations of the family S7-300 / S7-400 and the
corresponding TIM modules for remote transfer, the CP can be used for expansions by S7-
1200 stations.
The CP can be configured like a TIM 3V-IE Advanced so that it is compatible with all ST7
TIM modules.
1.2

Communications services

The following communications services are supported:
Telecontrol communication
The CP is the communications processor for connection of the SIMATIC S7-1200 via public
or private infrastructures to a telecontrol master station. You will find the possible application
of the telecontrol master station in the section Properties of the CP (Page 11).
