Depending on the firmware version the CP supports the following protocols.
●
– SINAUT ST7
●
– SINAUT ST7
– DNP3
– IEC 60870-5
You will find the supported transmission protocols and network types in the section

The CP can be used in the following systems:
●
In existing SINAUT systems in which the ST7 protocol is used, the CP can be used with
the functions of TIM 3V-IE Advanced.
If used for this purpose note the instructions below on configuration.
●
New systems with S7-1200 stations in which the ST7 protocol is used.
●
Existing DNP3 or IEC systems
In existing systems in which the DNP3 or the IEC protocol is used, the CP can be used
as the communications processor of the SIMATIC S7-1200.
The interfaces of the CP support the network node type "station". A master station can be
connected as the communications partner of the CP. When using the ST7 protocol, a master
station or node station can be connected.
Depending on the firmware version of the CP, a master station with one of the following
applications can be connected.
●
The following master station applications are possible:
– SINAUT ST7cc
– SINAUT ST7sc
– SIMATIC PCS 7 / WinCC TC
– SIMATIC WinCC OA
