13.2 SIMATIC Drive Controller firmware update
Compatibility information
Please note the following information on combinations of CPU and SINAMICS Integrated
firmware:
● An update at hotfix level is always possible.
● Restrictions apply to updates at the level of the main version for the "CPU firmware" and
"SINAMICS Integrated firmware" combination. Please note the compatibility information in
the relevant publications.
Note
If you insert the SIMATIC Memory Card in a SIMATIC Drive Controller with a higher
SINAMICS Integrated main firmware version, you need to upgrade your project to the
relevant SINAMICS version.
You can only go online with your project if the configured SINAMICS version corresponds to
the SINAMICS firmware version on the SIMATIC Drive Controller.
SINAMICS Integrated firmware missing or incompatible
If there is no SINAMICS Integrated firmware or the firmware is incompatible with the CPU,
this is signaled by a red flashing RDY LED (2 Hz) and a red ERROR LED. A corresponding
error message is also entered in the diagnostic buffer.
If the SIMATIC Memory Card has a SINAMICS Integrated firmware version that is
incompatible with the CPU firmware, the SINAMICS Integrated firmware update is rejected.
The ERROR LED lights up in red and the MAINT LED in yellow. A corresponding error
message is also entered in the diagnostic buffer.
An update of the CPU firmware, however, is always possible.
Note
Always run an update of the CPU and SINAMICS Integrated firmware main version first for
the CPU and then for SINAMICS Integrated. This ensure that an update is possible provided
the two versions are compatible.
If both update files (PLC and SINAMICS Integrated firmware) are stored on one update card,
the update is automatically performed in the order CPU -> SINAMICS Integrated.
Procedure: via the integrated Web server
The procedure is described in the Web Server
(https://support.industry.siemens.com/cs/ww/en/view/59193560) function manual.
Note
You can only perform an update for the CPU and not for the SINAMICS Integrated over the
SIMATIC Web server.
