Establishing an Online Connection and Making CPU Settings
18.4 Updating the Firmware
Programming with STEP 7
Manual, 05/2010, A5E02789666-01 413
Procedure in HW Config
1. Open the station containing the module to be updated.
2. Select the module
For PROFIBUS DP interface modules such as an IM 151, select the icon for the DP slave. In
this case, it is the one that stands for ET 200S.
3. Follow the same procedure for PROFINET IO devices.
If you want to update the firmware of modules of a DP slave or IO device, click the "Change
Slot" button and select the slot of the module you want to update in the "Change Slot" dialog.
4. Select the menu command PLC > Update Firmware.
You can only activate the menu command if the selected module / DP slave / IO device or the
selected submodule supports the "Update firmware" function.
5. In the "Update firmware" dialog that is displayed, click the "Browse" button and select the path
to the firmware update files (*.UPD).
6. After you have selected a file, the lower fields of the "Update firmware" dialog will contain
information telling you for which modules the file is suitable and as of which firmware version.
7. Click the "Run" button.
STEP 7 checks whether the selected file can be interpreted by the module. If the check result
is positive, the file is downloaded to the module.
If the operating mode of the CPU needs to be changed, dialogs will prompt you to carry out
these steps.
The module then carries out the firmware update independently.
Note: For a firmware update, such as to a CPU 317-2 PN/DP, a separate connection is usually
established to the CPU. In such case, the process can be interrupted. If no resources are
available for another connection, the existing connection is automatically used instead. In this
case, the connection cannot be interrupted. The "Cancel" button in the transfer dialog is grayed
out and unavailable.
8. In STEP 7, check (read out the CPU diagnostic buffer) whether the module was able to start up
with the new firmware.
Procedure in SIMATIC Manager
The procedure corresponds to that in HW Config. The menu command also is PLC > Firmware
update. STEP 7 however only checks if the module supports the function at the time of the
execution.
Firmware Update for Modules in Redundant Mode
As of STEP 7 V5.4, a firmware updates for a modules during redundant mode is supported, such
as for the IM 153-2BA00 with an active backplane bus at an H station. You can carry out a
firmware update for the redundant IMs in one process; the redundant IM will automatically be
provided with the latest firmware version.
Requirement: The programming device (PG) must be connected to the same PROFIBUS as one of
the IMs and you perform the update by means of "Accessible Nodes" in the SIMATIC Manager.
