Hi, please excuse my noob question, but I am totaly new to the Powerlink topic and I am kind of stuck. I hope I could get some help in this place. Till now I've used the exampIe from kalycito which works good for me. I'm using openConigurator (Standalone and Eclipseplugin) to generate my "Network-Layout". In a next step I have to implement a CN for a Powerlink Network that contains 2 Records (1 for TPDO, 1 for RPDO) From this thread I suspect I have to link each sub-object on its own, but.... How?...
