Updating firmware
Basic procedure
To update the firmware of a CPU, you will receive several files (*.UPD) containing the
current firmware. You download these files to the CPU.
Requirement
The CPU whose firmware you want to update must be accessible online, e.g., via
PROFIBUS or Industrial Ethernet. The files containing the current firmware versions must be
downloaded into the programming device/PC file system. A folder may contain only the files
of one firmware version. If the CPU is protected with a password, you need the respective
password for the update.
Note any information posted in the firmware download area.
Procedure in HW Config
Proceed as follows to update the firmware of a CPU:
1.
Open the station containing the CPU you want to update in HW Config.
2.
Select the CPU.
3.
Select the "PLC -> Update Firmware" menu command.
4.
In the "Update Firmware" dialog, select the path to the firmware update files (*.UPD)
using the "Browse" button.
After you have selected a file, the information in the bottom boxes of the "Update
Firmware" dialog box indicate the modules for which the file is suitable and from which
firmware version.
5.
Click on "Run".
STEP 7 verifies that the selected file can be interpreted by the CPU and then downloads the
file to the CPU. Every time you have to change the operating state of the CPU, you are
prompted to do this in the relevant dialog boxes.
Procedure in SIMATIC Manager
The procedure corresponds to that in HW Config; the menu command here is also "PLC >
Update firmware". However, STEP 7 checks whether the module supports the function only
at the time of execution.
Note
Checking the firmware update files (*.UPD)
The CPU checks the firmware update files (*.UPD) during the update process. If an error is
detected, the old firmware remains active and the new firmware is rejected.
