Communication PROFIBUS DP/PROFINET IO 10.2 Communication via PROFIBUS DP

10.2.2.4SIMATIC 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

(data block offset)

Bit 15 – 10: Drive object no. 0 ... 63

 

Bit 9 – 0: Sub-index 0 ... 1023

 

In other words:
