3.5 Diagnostics channels
SINAMICS drives provide the standard diagnostics for PROFIBUS and PROFINET. This
allows the PROFIdrive classes of the SINAMICS 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
r3120[0..63] component fault
r2122[0...63] alarm code
r3121[0..63] component alarm
r9747[0...63] SI message code
(with safety messages)
r9745[0..63] SI component
(with safety message)
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 through appropriate parameterization in the configuring tools
used (e.g. using HW Config or via HWCN in the TIA Portal).
The functional scope of the diagnostic channels depends on the bus system.
PROFIdrive message classes
PN
DP GSD X - -
● SINAMICS transfers the messages in the sequence in which they occurred.
● If an alarm appears, SINAMICS sends an "incoming" message. The alarm remains until
SINAMICS sends the corresponding "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 fa
ults and alarms are provided in
the SINAMICS List Manuals.
