9.4
Online (via networks) update of CPU FW V2.2.0 or higher.
To update the CPU firmware, you require the *.UPD files containing the latest FW version.
Requirements
•
Online FW updates can be performed in STEP 7 V5.3 or higher.
•
The module at the station whose firmware should be updated must be online.
•
The files containing the current FW version must be available in the file system of your
PG or PC. A folder may contain only the files of one firmware version.
Performing a firmware update
1. Run STEP 7 and change to HW Config.
2. Open the station containing the CPU you want to update.
3. Select the CPU.
4. Select PLC > Update Firmware. The menu command can only be executed if the
selected CPU supports the "Update Firmware" function.
5. On the "Update Firmware" dialog, select the path to the FW update files (*.UPD) using
the "Search" button.
6. After you selected a file, the information in the lower fields of the "Update Firmware"
dialog box shows you the FW file and version for the corresponding modules.
7. Click "Run." STEP 7 verifies that the selected file can be interpreted by the module, and
then downloads the file to the CPU. If this requires changing the operating state of the
CPU, you will be asked to perform these tasks in the relevant dialog boxes. The CPU
then automatically updates the firmware.
8. In STEP 7 (reading the CPU diagnostics buffer), verify that the CPU can start with the
new firmware.
Result
You updated the CPU online with a new firmware version.
