7.5.3.3 Commissioning PROFIBUS
Preconditions and assumptions for commissioning
PROFIBUS slave
● The PROFIBUS address to be set for the application is known.
PROFIBUS master
● The communication properties of the SINAMICS DCP slave must be available 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 the HW Config:
– Connect the drive unit to PROFIBUS and assign the address.
– Set the telegram type.
SINAMICS DCP only supports the "Free telegram configuration with BICO".
The master can send more process data than the slave uses. A telegram with a larger
PZD number than is assigned for the drive object STARTER can be configured on the
master.
The PZDs not supplied by the drive object are filled with zeros.
The setting "without PZD" can also be defined for a node or object.
4. Assign the I/O addresses according to the user program.
7.5.3.4 Diagnostics options
The standard slave diagnostics can be read online in the HW Config.
7.5.3.5 SIMATIC HMI addressing
You can use a SIMATIC HMI as a PROFIBUS master (master class 2) to access SINAMICS
directly. With respect to SIMATIC HMI, SINAMICS behaves like a SIMATIC S7. For
accessing drive parameters, the following simple rule applies:
● Parameter number = data block number
● Parameter subindex = bit 0 ... 9 of data block offset
● Drive object number = bit 10 ... 15 of data block offset
