Setting of a fixed PROFIBUS address on the SINAMICS S120
In general, for the operation of the SINAMICS S120 together with the Technology CPU,
the setting of a fixed PROFIBUS address using the DIP or rotary switches directly on the
SINAMICS S120 is recommended.
When the values 0 or 127 are set, the PROFIBUS address set in the p0918 parameter will
be is used for the communication.
Note
The address 126 in the p0918 parameter of the SINAMICS S120 is set as default setting of
the PROFIBUS address. To prevent access problems caused by an unknown
PROFIBUS address during the commissioning, the address should be predefined using
the DIP or rotary switches before the commissioning (e.g. "address 4").
Note
When you use a CB10 (CAN bus interface) or CBE20 (PROFINET interface) option module,
the SINAMICS firmware switches off the PROFIBUS interface. It is not possible to run two
different communication interfaces in parallel. It is not possible to switch off a configured
CB10 (CAN bus interface) or CBE20 (PROFINET interface) option module via configuration.
