Procedure: online in STEP 7 via Online & diagnostics
Requirements:
• There is an online connection between CPU/CP/PROFINET IO device, and PG/PC, and the
CPU is configured.
• Observe the procedure under "Installation of the firmware update of R/H-CPUs".
Proceed as follows to perform a firmware update online via STEP 7:
1. Select the module in the device view.
2. Select the "Online & diagnostics" menu command from the shortcut menu.
3. In the "Functions" folder, select the "Firmware update" group.
For a CPU, you can select whether you want to update the CPU or the display (not with R-
CPUs as of FW version V3.0).
4. Click the "Browse" button to select the path to the firmware update files in the "Firmware
update" area.
5. Select the correct 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. If you need to change the CPU operating state, STEP 7 prompts
you to do so with dialogs.
Note
Updating PROFINET IO device
The R/H system remains in the RUN-Redundant system state if you update an IO device.
Note
Updating a communications processor
CP firmware updates can only be executed in the STOP operating mode of the associated R/H-
CPU.
Updating the firmware
The "Run firmware after update" check box is always selected.
Once the files have been successfully loaded, the CPU accepts the firmware and operates
with the new firmware.
