Communication PROFIBUS DP/PROFINET IO 10.2 Communication via PROFIBUS DP

Figure 10-44 Hardware catalog of the GSD file with slave-to-slave communication functionality

The SINAMICS S DXB GSD file contains standard telegrams, free telegrams and slave-to- slave telegrams for configuring slave-to-slave communication. The user must take these telegram parts and an axis delimiter after each DO to compose a telegram for the drive unit.

The processing of a GSD file in HW Config is covered by the SIMATIC documentation.

10.2.4.6Diagnosing the PROFIBUS slave-to-slave communication in STARTER

Diagnostics

Since the PROFIBUS slave-to-slave communication is implemented on the basis of a broadcast telegram, only the subscriber can detect connection or data faults, e.g. via the Publisher data length (see "Configuration telegram").

The Publisher can only detect and report an interruption of the cyclic connection to the DP master (A1920, F1910). The broadcast telegram to the subscriber will not provide any feedback. A fault of a subscriber must be fed back via slave-to-slave communication. In case of a "master drive" 1:n, however, the limited quantity framework (see "Links and requests") should be observed. It is not possible to have n subscribers report their status via slave-to- slave communication directly to the "master drive" (Publisher)!
