Downloading firmware
13.1 Loading using the Firmware Loader
Note
Security enabled
If security is enabled on modules, it is not possible to load firmware using the Firmware
Loader.
Instead, we recommend that you load the firmware when necessary using the update center
in Web diagnostics.
To load the firmware on the module using the Firmware Loader, the module must be in the
"security disabled" status. Where necessary, one of the following steps is therefore
necessary:
• Reset the module to the factory settings;
or
• Download the configuration data to the module without security enabled.
Installation
The firmware loader is available when you have installed STEP 7 on your PG/PC.
Load files
The firmware loader supports the following file types:
● <file>.FWL
A file form that contains extra information that can be displayed in the dialogs of the
firmware loader in addition to the actual firmware. Based on this information, the firmware
loader can check the firmware for compatibility with the device.
For detailed information, read the documentation, for example, the README file that ships
with the load file.
This information is displayed even after reading in the FWL file into the firmware loader.
Working with the Firmware Loader
Depending on the module type, the downloading is prepared and executed in three or four
steps.
You will find further information in the dialog boxes and in the online help.
Starting to load firmware (STEP 7 V5.5)
Open the Windows Start menu and select the menu command "SIMATIC" "STEP 7" > "NCM
S7" > "Firmware Loader".
