9.4 Communication via PROFINET IO
Function Manual
674 Function Manual, 06/2012, 6SL3097-4AB10-0BP4
● Configure the PROFINET communication in HW Config (see section "Configuring the
controls").
● When the system is booting, because p8929 = 2, SINAMICS S recognizes that
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.
9.4.7.2 Configuring the controls
You have two options for configuring both the controls A-CPU and F-CPU in HW Config :
Configure
● both controls using the Shared Device function in a common project or
● each control in a separate project.
Note
You can find more detailed information on configuring with HW Config in the STEP7
documentation.
