• The update center of the Web server
You can reach the update center using Web diagnostics.
The CP supports the storage of several firmware versions. Using the firmware load
function in the update center, you can activate the required firmware version.
Requirement: The "Firmware download via Web" option is selected in the configuration
and the user rights have been set.
Note the descriptions of firmware downloads in the manual Part A /2/ (Page 103).
Note
Security functions enabled:
If the Sec
urity functions are enabled for modules, a protection level is automatically
configured that prevents loading a new firmware file with the firmware loader.
Instead, we recommend that you load the firmware when necessary using the update center
in Web diagn
ostics.
To load the firmware on the module using the firmware loader anyway, the CPU and the CP
must be in STOP mode.
How to download new firmware
You can download the firmware via both interfaces of the CP.
Note
Operation with CPU version
< V6.0
Remember that the CPU with version < V6.0 changes to STOP during downloading of the
firmware if you are using PROFINET IO communication.
Follow the steps outlined below:
1. Connect the CP module to the PG/PC via a LAN cable.
2. Start the download on your PG/PC using one of the firmware download functions described
above.
You can find the corresponding LED displays in the section LEDs (Page 37). Downloading
new firmware via the update center does not affect the LED display.
The download involves two stages:
– Section 1: Downloading firmware
– Section 2: Activating firmware
3. After the firmware download, the CP goes through a warm restart.
If the download using the firmware loader is aborted, the RUN and STOP LEDs flash
alternately.
