How to perform a firmware update for the CPU (as of V5.0)

You are provided with several files (*.UPD) with the latest firmware to update the firmware of
a CPU. Download these files to the CPU. You do not need a memory card for the online update.
However, it is still possible to perform a firmware update with a memory card.
Preparation
Compare the type and manufacture date of the modules you are using with the information in
the document
If replacement of the CPU is required, contact your Siemens representative.
Requirements
● STEP 7 V5.3 or higher is installed on the programming device or PC.
● The update file for the firmware update is available on the programming device/PC.
● The CPU, whose firmware is to be updated, must be accessible online, for example, via
36
PCS 7 Released Modules.
PROFIBUS, MPI or Industrial Ethernet. The files containing the latest version of the
firmware are available in the file system of your programming device or PC. A folder may
only contain the files for one firmware version.
Note
For CPUs with a PROFINET interface, you can update the firmware via Industrial Ethernet
on the PROFINET interface. Updating via Industrial Ethernet is significantly faster than
MPI or DP (depending on the configured baud rate).
You can update the firmware of the other CPUs via Industrial Ethernet, if the CPU is
connected to Industrial Ethernet via a CP.
