Configuring Shared Device - Siemens SINAMICS S120 Series Function Manual

Note
CPU failure
Communication is carried out by both controllers 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.

project
● Using GDSML, you configure each controller independently in its own project
The first of these options is described in the following example.
