<p><P>PROBLEM TO BE SOLVED: To provide a communication system, device and method, allowing the communication devices to have the same configuration without giving identification information peculiar to each communication device, and reducing man-hours. <P>SOLUTION: Each of input/output devices 2a, 2b, 2c cuts off switches 201a, 201b, 201c of first paths of connection switching parts 20a, 20b, 20c, measures a current value I in input current values I<SB>1</SB>, I<SB>2</SB>, I<SB>3</SB>and each resistor R in the state where switches 202a, 202b, 202c connected to the resistor R connected to a second path in parallel with the first path are connected, and determines a self-address from the current value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
