Update OS
Use "Update OS" to update the operating system of the HMI device. The operating system is
contained in several firmware files. The master file has the extension ".fwf". The number of
additional files varies; these files have the file name of the master file and a sequential
number (".0", ".1", ".2", etc.) as an extension.
The "Update OS" function is available under both "System Properties" and "Service and
Commissioning".
NOTICE
Updating the operating system deletes data on the HMI device
Project, parameter sets and user administration will be deleted when you update the
operating system on the HMI device.
Before updating the operating system, backup the data on the HMI device, if necessary.
All settings, except the following settings which you changed in the Control Panel before
updating the operating system, are retained even after the update of the operating system:
•
The external interfaces become activated again (default setting), see section
"Network settings (Page 87)".
•
The time zone is reset to the default setting "(UTC) Coordinated Universal Time", see
section "Remote connection (Page 91)".
Use a SIMATIC SD memory card with 32 GB or more or an industrial USB flash drive to load
the firmware.
Firmware files for the HMI devices can be downloaded from the Internet
https://support.industry.siemens.com/cs/ww/en/view/109746530
). Observe the
documentation included with the download.
Note
Do not rename firmware files
If you change the name of the firmware files, the operating system can no longer be updated
with these firmware files. The firmware files become unusable. Leave the name of the
firmware files unchanged.
Copy firmware files completely
If you copy the firmware files, be sure to also copy the master file ".fwf" together with all
associated firmware files (".0", ".1", ".2", etc.).
If one of the files is missing, the operating system cannot be loaded.
Alternatively to the "Update OS" function in the Control Panel, you can use the "Update OS"
function in WinCC.
