Configuring the communication

TIA (Totally Integrated Automation)
The program for SIMATIC S7-300/400F and the configuration of the SINAMICS G
are centrally stored in a STEP 7 project. The respectively required editors are
called up via the STEP 7 Manager.

SIMATIC S7-300/400F

In this example, the SIMATIC S7-300/400F is programmed with STEP 7 V5.
In HW Config, the SIMATIC S7 the stations connected via PROFIBUS, such as
SINAMICS G, are configured, and the communication is defined. One of several
message frame types can be selected here for the data exchange. It is important
that the same message frame type is selected here as for the SINAMICS G
configuration.
Exchanging safety-relevant data an additional PROFIsafe message frame is
selected.
When inserting SINAMICS G into the SIMATIC project, the I/O addresses used by
the SIMATIC S7-300/400F for accessing the SINAMICS G are also specified.

SINAMICS G

The configuration of SINAMICS G is performed using the STARTER
commissioning tool.
For SINAMICS G one of several message frame types can be selected for the data
exchange. This defines which data is transmitted or received in which order. It is
important that the same message frame type is selected when configuring the
SIMATIC S7-300/400F.
The PROFIsafe message frame for exchanging failsafe data is automatically
selected upon activating the respective safety function.
2.2.2

Data exchange

Data exchange between SINAMICS G and PLC occurs in two areas:
Process data,
i.e. control word(s) and setpoint(s), or status word(s) and real value(s)
Parameter area,
i.e. reading/writing of parameter values
Note The two areas, process data and parameters, are independent from each other
and can also be used individually.
