Hello, In the EPSG Draft Standard 301 the addressing for MAC addresses and Powerlink addresses are explained (chapter 4.4 & 4.5). How is the mapping of a powerlink node ID (e.g. 20) to a particular MAC address done? Is this statically coded into the MN? Especially for the PollRequest that is a unicast transfer type, how does the MN determine the the MAC address of the CN, whoes node ID is in the destination field of the PollRequest? Thanks for your help. Best regards.
