7.3 Loading new firmware
Options for a firmware update
The following alternative methods can be used to download new firmware to a SIMATIC NET
CP:
• Using the firmware loader supplied with STEP 7
Requirement for downloading:
– To download firmware, you require an Industrial Ethernet CP module in the PG/PC (for
example, CP 1613) or a normal Ethernet module with the "Softnet" software package.
– The S7ONLINE interface must be set to the "ISO - Industrial Ethernet" protocol. It is not
possible to download using TCP/IP (and therefore not to other networks).
• Via the update center in the Web diagnostics of the CP
With this method, the CP remains in RUN mode.
You can reach the update center using Web diagnostics.
Requirement: The option "Firmware download via Web" is selected in the configuration.
Both options for loading the firmware are described in the manual Part A, see /1/ (Page 73).
LED displays when loading a firmware file
The LED combinations when loading a firmware file using the STEP 7 firmware loader can be
found in the section LEDs (Page 29).
When loading a firmware file using the update center in Web diagnostics, the LEDs of the CP
remain unchanged.
If the loading with the firmware loader is interrupted, you should react as follows:
Disturbances or collisions on the network can lead to packets being lost. In such cases, this
can lead to an interruption of the firmware download. The firmware loader then signals a
timeout or negative response from the module being loaded.
In this case, turn the station off and on again and repeat the download.
