Replacing A Module - Siemens CP 343-1 Manual

● 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 71).
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.

Note
Recommendation to reset address data if the use of the CP is changed
The following data is stored permanently on the CP:
• A configured MAC address
• IP parameters when using DHCP
If the CP has already been operated in your plant and you want to use it at a different
location in the plant, it starts up with the permanently configured parameters.
If the CP has been used previously in your plant or has been repaired, delete all stored data
by resetting to the factory settings.
