5.4.9.6 System upgrade
This page allows you upgrade the firmware for CIM.
Prerequisites
Download the upgrade package from After sales information system
(https://support.industry.siemens.com/cs/start?lc=en-US).
Upgrade the firmware
Upgrade firmware will not change any configuration. However, Siemens recommends you
backup configuration data through the path System Setting --> System Configuration
Management before the upgrading.
In the upgrade environment, other functions of the system are stopped, such as network
communication, data bindings and so on.
Follow these steps to perform an upgrade:
1. Click "Upgrade system" in the system upgrade page.
2. Navigate to the folder which you saved the upgrade package and select it.
3. Wait until the upgrade completed.
Note
Do not power off the device, disconnect the device or refresh the page during the
upgrade. Otherwise, the upgrade may fail.
CIM restarts to utilize the new features after the upgrade completed.
