Anybody has the experience of profibus-dp drop connector in MCC/distributed starter design? I am designing the profibus-dp installation for tens of separate starter/VFD cabinets in the electrical room. First, do I need to have drop connector connecting to the individual starter/VFD cabinet or connect the BUS cable directly to the screw terminals in the individual starter/VFD cabinet? Second,who will supply the power to the Profibus-dp communication, the master?
