10.4 Communication via PROFIBUS DP
SINAMICS DCM DC Converter
464 Operating Instructions, 12/2018, A5E34763375A
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.
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
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 be defined on a node or object (e.g. infeed controlled
via terminals).
4. Assign the I/O addresses according to the user program.
The standard slave diagnostics can be read online in the HW config.
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 sub-index = bit 0 ... 9 of data block offset
● Drive object number = bit 10 ... 15 of data block offset
Pro Tool and WinCC flexible
The SIMATIC HMI can be configured flexibly with "Pro Tool" or "WinCC flexible".
The following specific settings for drives must be observed when configuration is carried out
with Pro Tool or WinCC flexible.
Controllers: Protocol always "SIMATIC S7 - 300/400"
