Configuring Shared Device - Siemens SINAMICS S120 Function Manual

Communication
11.3 Communication via PROFINET IO
Note
When booting, the drive system first requires the configuration data of A-CPU and then
establishes a cyclic communication to this CPU taking into account the PROFIsafe telegrams
expected.
As soon as the drive system has received the configuration data of the F-CPU, then cyclic
communication is also established here and PROFIsafe telegrams are taken into
consideration.
NOTICE
CPU failure
Communication via the two channels functions independently of one another. In the event
of failure of a CPU, communication with the other CPU is not interrupted, it continues to
operate without interruption. Error messages are output regarding the components that
have failed. Resolve the fault and acknowledge the messages; communication to the CPU
that failed is then automatically restored.
11.3.8.2

Configuring Shared Device

You have the following two options in HW Config when configuring the two controllers A-
CPU and F-CPU:
● You configure both of the controllers using the Shared Device function in a common
project.
● Using GDSML, you configure each controller independently in its own project.
The first of these options is described in the following example.
Note
Detailed information on configuring with HW Config is provided in the STEP 7
documentation.
