The PCD8.K120 Profi-S-Link forgets it's IP address after power down

FAQ #100280

 

It is important to distinguish between a temporary IP address that is stored in RAM (which is foreseen to be able to download a configuration to the PCD8. K120) and a configured IP address that is stored in Flash-EPROM. If your unit "forgets" the IP address during a power down you probably only assigned a temporary IP address, but didn't download a correct configuration.
