10.3.2.7 Diagnostics channels for cyclic communication
Alarms and faults can be transferred via two independent diagnostic channels DS0 and DS1.
The information transferred is saved in parameters r0945[8] for faults and in r2122[8] for
alarms. This allows the alarms and faults from a SINAMICS drive to be integrated into the
system diagnostics of a higher-level controller and automatically displayed on an HMI. This
function is certified for PROFINET and PROFIdrive.
The function is activated via the appropriate parameterization in the configuration tool being
used, e.g. using HW Config or TIA Portal. The functionality is then transferred at the next
power up to drive.
The messages of the diagnostic channels depend on the bus system being used for data
transfer.

● The alarms and faults correspond to the error classes defined in the PROFIdrive profile.
● You can select whether alarms and faults are transferred to a higher-level controller either
as SINAMICS messages or using the error classes of the PROFIdrive profile.
● The alarms and faults can be mapped with standard resources (e.g. GSDML)
● The alarms or faults are logically and locally signaled:
– With alarm or fault number
– With assignment of the drive object, message value and hardware component
– In a user-friendly way with plain message texts
– Display with user-defined names for drive objects and components
– SINAMICS transfers the messages in the order that they have occurred
– SINAMICS does not record any time stamps
– The time stamps are generated from the higher-level controller when the messages
– To transfer the SINAMICS messages, the extended channel diagnostics is used
● The existing mechanisms of TIA and S7 Classic can be used.
● The messages are compatible with PROFINET controllers.
● Alarms or faults are acknowledged using the already known acknowledgment routes.
● Transfer possible via interface IF1 and/or IF2
