10.2.2.4 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 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"

Drive object no. and subindex
Bit 15 – 10: Drive object no. 0 ... 63
Bit 9 – 0: Sub-index 0 ... 1023
In other words:
DBW = 1024 * drive object no. + sub-index
