Mapping the IP address and subnet mask
The network address, the subnet mask, and the PROFINET device name are defined by auto-configuration. You must configure these parameters accordingly in the higher-level PROFINET master.
The auto-configuration assigns the node address 192.168.10.20 to the furthest upstream ECC-DFC fieldbus controller. Every other fieldbus controller is then assigned a corresponding node address in ascending order (192.168.10.21, 192.168.10.22).
