Configuring Shared Device - Siemens Sinamics S120 Function Manual

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.

Configuring Shared Device

In HW Config you have the following two options when configuring the two controls A-CPU
and F-CPU:
1. You configure both of the controls using the Shared Device function in a common project
2. Using GDSML, you configure each control independently in its own project.
We describe the first configuring option in the example below.
Note
Detailed information on configuring with HW Config is provided in the Step7 documentation.
Example: Two controls in a common project
To do this, start Step7:
1. Under S7, create a drive control for the new project, in the example called A-CPU, based
