<p><P>PROBLEM TO BE SOLVED: To solve the problem that in a conventional M:N communication system wherein controllers and devices transmit data respectively optionally the reliability of communication is degraded. <P>SOLUTION: The communication system disclosed herein includes one device acting like a master node, and the other devices connected to the same sub-net acting like general nodes. When the general nodes transmit data, the general nodes transmit the data to the master node without fail, the master node discriminates the transmission destination on the basis of the address of the received data and carries out routing so as to realize 1:N communication thereby enhancing the reliability of communication. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
