Installation of the firmware update
Impermissible plant states possible
Installation of the firmware update causes the CPU to switch to STOP mode. STOP may
affect 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.
Ensure before installing the firmware update that the CPU is not controlling any active
process.
Procedure: online in STEP 7 via Online & diagnostics
Requirements: There is an online connection between the CPU/module and PG/PC.
To perform a firmware update online via STEP 7, follow these steps:
1. Select the module in the device view.
2. Select the "Online & diagnostics" menu command from the shortcut menu.
3. Select the "Firmware update" group in the "Functions" folder.
4. To select the path to the firmware update files, click the "Browse" button in the "Firmware
update" area.
5. Select the matching firmware file. The table in the "firmware loader" 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. If you must change the CPU mode, STEP 7 prompts you to
do so with dialogs.
Updating the firmware
The "Run firmware after update" check box is always selected.
After a successful loading operation, the module receives the firmware and then operates
with this new firmware.
Note
If a firmware update is interrupted, you must switch off the supply voltage of the CPU and
then switch it on again before repeating the firmware update.
