Updating the operating system

6.7.1

Overview and important notes

The firmware and operating system version of the HMI device must be compatible with the
firmware and operating system version of the installed WinCC software. If this is not the
case, then you must update the operating system. If the operating system on the HMI device
is no longer functional, you must reset the HMI device to factory settings.
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
• The time zone is reset to the default setting "(UTC) Coordinated Universal Time", see
When the operating system is reset to factory settings, all data of the HMI device is deleted
and all settings in the Control Panel are reset to factory settings.
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.
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.
