12.6 Firmware update
Installation of the firmware update
Risk of impermissible system states
The CPU switches to STOP mode or the interface module to "station failure" as a result of
the firmware update being installed. STOP or station failure can have an adverse effect on
the operation of an online process or a machine.
Unexpected operation of a process or a machine can lead to fatal or severe injuries and/or
to material damages.
Make sure that the CPU/interface module is not executing any active process before
installing the firmware update.
Procedure using STEP 7
Proceed as follows to perform an online firmware update with STEP 7:
1. Select the module in the device view.
2. Select the "Online & diagnostics" command from the shortcut menu.
3. Select the "Firmware update" group in the "Functions" folder.
4. Click the "Browse" button to select the path to the firmware update files in the "Firmware
update" area.
5. Select the suitable firmware file. The table in the firmware update area lists all modules
for which an update is possible with the selected firmware file.
6. Click the "Run update" button. If the module can interpret the selected file, the file is
downloaded to the module.
Updating the firmware
The "Run firmware after update" check box is always selected.
When the loading process is complete, the CPU adopts the firmware and then operates with
this new firmware.
Note
If a firmware update is interrupted, you need to remove and insert the module before starting
the firmware update again.
