Configuration
Proceed as follows to configure the connection:
● Use parameter p8929 = 2 to specify that data from 2 controls is to be received via the
● Enable PROFIsafe with parameter p9601.3 = p9801.3 = 1.
● Configure the PROFINET communication in HW Config (see section "Configuring the

PROFINET-interface.
controls").
PROFINET telegrams from 2 controls are expected, and structures the communication
according to the configuration in HW Config.
Note
When booting, SINAMICS S needs the configuration data of the A-CPU first, and then
establishes the cyclic communication to this CPU – taking into account the expected
PROFIsafe telegrams.
As soon as SINAMICS S has subsequently received the configuration of the F-CPU,
cyclic communication is also established here and the PROFIsafe telegrams are taken
into account.
CAUTION
Failure of a CPU
If a CPU fails, communication with the other CPUs is not interrupted. Communication via
both channels works independently of each other.
If a CPU fails, communication with the other CPUs continues to function without
interruption. Fault messages regarding the failed component are output. Resolve the
fault and acknowledge the messages, then communication with the failed CPU will be
re-established automatically.
