● Configurations and stored data of the freely configurable channels (DIQ<n>)
● Commissioning history and diagnostics buffer
After the reset, the CFU restarts automatically.
The subsequent reaction depends on whether or not the PROFINET topology is configured in
HW Config:
● If the PROFINET topology is configured in HW Config:
After the reset, the CFU automatically receives the device name and IP address by means
of neighborhood detection.
● If the PROFINET topology is not configured in HW Config:
You must enter the device name and IP address for the CFU again and download all data
of the CFU.
You can find additional information about this in section "Preparing the CFU for
commissioning (Page 76)".
