Diagnostic channels
The drive provides the standard diagnostics for PROFIBUS and PROFINET. This allows the
PROFIdrive classes of the drive to be integrated into the system diagnostics of a higher-level
control system and automatically displayed on an HMI.
The information transferred is saved for the drive objects in the following parameters:
• r0947[0...63] fault number
• r2122[0...63] alarm code
• r9747[0...63] SI message code
(with safety messages)
The messages entered in these parameters are combined to create PROFIdrive message
classes for diagnostics. Determining the source of a message is realized by transferring the
component number as channel number.
The diagnostics are activated via the appropriate parameterization in the configuration tool
being used (e.g. via HW Config).
The functional scope of the diagnostic channels depends on the bus system.
PROFINET
PROFIBUS
● The drive transfers the messages in the sequence in which they occurred.
● When a message occurs, the drive sends a communication message. The message
remains until the drive sends the associated outgoing message.
● The time stamps are generated from the higher-level controller when the messages are
received
● The existing mechanisms of TIA and S7 Classic can be used.
● Alarms or faults are acknowledged using the already known acknowledgment routes.
● Transfer is possible via interface IF1 and/or IF2.
Note
Constraint
If a shared device is activated, only the A-controller can receive diagnostics.
Note
Additional information
PROFIdrive message classes of the individual SINAMICS faults and alarms are provided in
the List Manual.
