It is recommended to generate a backup even on a new system as well as
prior to any changes in the system (e.g. firmware update) and to store it se-
curely in case a restore becomes necessary at a later point in time.
The execution of the maintenance measures is described in the respective
project engineering manuals.
16.1 Executing a firmware update of the system components
The u-create system permits the central, automatic update of the software
running on the hardware modules.
There are the following variants of updates:
● Run update automatically when the control is started up
Before the firmware update can be implemented, a removable disk (e.g. SD
card) with the relevant data must be created.
Preparation
The following is required for the preparation of the firmware update:
● An empty removable disk with min. 2 GB.
● Run-compatible system on the control (must not have the latest version
status).
● The required storage medium must be plugged into the PC.
● Firmware update tool installed on the PC.
The firmware update tool provides the following options:
● Firmware update for control and bus coupler
