4.2.3 Commissioning PROFIBUS
Preconditions and assumptions for commissioning
PROFIBUS slave
• The PROFIBUS address to be set for the device application is known.
• The telegram type for each drive object is known by the application.
PROFIBUS master
• The communication properties of the SINAMICS S120 slave must be availa-
ble in the master (GSD file or Drive ES slave OM).
Commissioning steps (example with SIMATIC S7)
1. Set the PROFIBUS address on the slave.
2. Set the telegram type on the slave.
3. Perform the following in HW Config:
– Connect the drive unit to PROFIBUS and assign the address.
– Set the telegram type.
The same telegram type as on the slave should be set for every drive object
exchanging process data via PROFIBUS.
The master can send more process data than the slave uses. A telegram with a larger
number of PZDs than assigned for the SINAMICS drive object can be configured on
the master.
The PZDs not supplied by the drive object are filled with zeros.
The setting "without PZD" can be defined on a node or object (e.g. infeed controlled
via terminals).
4. Assign the I/O addresses according to the user program.
