Installation of the firmware update
Impermissible plant states possible
Installation of the firmware update causes the CPU to switch to STOP or a distributed
interface module to "station failure". The STOP operating state results in a frame failure at
the drive with a corresponding response at the drive end (for example, OFF3 fast stop,
depends on the parameter assignment). STOP or station failure can have an adverse effect
on the operation of an online process or a machine.
Unexpected operation of a process or a machine can lead to fatal or severe injuries and/or to
material damages.
Before you install the firmware update, make sure that the SIMATIC Drive Controller is not
controlling any active process.
Note
Management of the license conditions and copyright notices of firmware updates
Open-source software is used in the firmware of the SIMATIC Drive Controllers. For legal
reasons, Siemens AG is obliged to publish the original text of the license conditions and
copyright notices. You can find it on the Internet in the FW downloads
(https://support.industry.siemens.com/cs/de/en/view/109773914) and in the scope of supply
of the SIMATIC Drive Controller for the firmware version that has been supplied (see the note
on the type plate at the side).
The license conditions and copyright notices in the scope of delivery can change as a result of
firmware updates. In order to avoid license violations by the reseller and the buyer, if there
are firmware updates, you must pass on the license conditions and copyright notices of the
firmware update to the buyer (for example, by saving them to the SIMATIC Memory Card).
Procedure: online in STEP 7 via Online & diagnostics
