Abstract
P2P (Peer-to-Peer) technology spread explosively as a method of exchanging the music data etc, on the Internet for a certain period of time. We think about its application to the FA (Factory Automation) field. When the configuration of FA controllers connected on the network is changed, the parameters of them or of their applications might have to be recreated. UPnP (Universal Plug and Play) is one of the implementation methods of the automatic setting that P2P requires. Trouble of complex settings could be saved by installing the function of UPnP in FA controllers.
