PROBLEM TO BE SOLVED: To provide a communication slave capable of appropriately setting an ID respectively without inserting a switch to a bus.;SOLUTION: In a communication bus 3H via the slave 2, a shunt resistor 11 is inserted downstream of a point at which a control circuit 10 is connected. The control circuit 10 sets the ID for communicating with a master 1 corresponding to a potential difference level between communication buses 3H, 3L detected by an A/D conversion circuit 12.;COPYRIGHT: (C)2011,JPO&INPIT
