6.1 Overview
Unified Comfort Panels
122 Operating Instructions, 03/2020, A5E46641217-AA
Updating the operating system of the HMI device
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, an error message is output before the transfer.
You can update the operating system of the HMI device in the following ways:
● Transfer of the operating system together with the project from a configuration PC to the
HMI device, see section "Transferring a project with WinCC (Page 125)".
● Transfer of the operating system from a configuration PC to the HMI device, see section
"Updating the operating system via WinCC (Page 132)".
● Transfer of the operating system from a data storage medium to the HMI device, see
section "Update OS (Page 104)".
● Insert a prepared system memory card from an identical HMI device, see section
"Automatic backup (Page 108)".
● Restore the backup file of an identical HMI device from an external storage medium, see
section "Restore (Page 112)".
If the operating system cannot be updated with the above options, then you must reset the
HMI device to factory settings.
You can reset the HMI device to the factory settings in the following ways:
● If the HMI device starts and you have access to the Control Panel, proceed as described
in section "Resetting an HMI device to factory settings via ProSave (Page 133)".
● If the HMI device does not start or you do not have access to the Control Panel of the
HMI device, then start the HMI device in maintenance mode, see section
"Using the maintenance mode (Page 136)".
Process control phase
In the process control phase, the HMI device is connected online to a controller, and you can
operate and monitor the plant.
Commissioning and recommissioning
Initial commissioning and recommissioning differ as follows:
● During initial commissioning, no project is available on HMI device.
The HMI device has this status when delivered and after updating of the operating
system.
● When recommissioning, the project already on the HMI device is replaced.
