A.1.2.4 Messages Via Diagnostic Channels_Profibus - Siemens SINAMICS Configuration Manual

r2074 and r2075 enable the source of a slave-to-slave communication relationship to be
verified in the subscriber.
Note
The subscribers do not monitor the existence of an isochronous publisher sign-of-life.
Faults and alarms with PROFIBUS slave-to-slave communication
The alarm A01945 signals that the connection to a least one publisher of the drive device is
missing or has failed. Any interruption to the publisher is also reported by the fault F01946 at
the affected drive object. A failure of the publisher only impacts the respective drive objects.
Detailed information on the messages is available in the converter List Manual.
A.1.2.4 Messages via diagnostic channels_PROFIBUS
Messages can be displayed not only via the well-known commissioning tools (STARTER,
SCOUT). After the activation of a diagnostic function, the messages are also transferred to
the higher-level controller via the standardized PROFIdrive fault classes. The messages are
evaluated there or forwarded for convenient display to the corresponding user interfaces
(SIMATIC HMI, TIA Portal, etc.).
In this way, problems or faults can be located immediately regardless of the tool currently being
used, and then corrected immediately.
Also note the general information on the diagnostics channels in chapter Diagnostics
channels (Page 105).
