10 How to Load New Firmware 
Requirements
You download new firmware to a SIMATIC NET CP using the firmware loader
shipped with STEP 7 / NCM S7.
Requirements for Downloading
S 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.
S The S7-ONLINE 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).
How to Download New Firmware
You always start the download using the active MAC address of the CP!

What to do if a Download is Interrupted 
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.
