Title:
COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/013668
Kind Code:
A1
Abstract:
A communication system (1) is configured to be able to implement an address allocation process including: a first process in which, when an identification current output is generated by constant current sources (CI7 to CI1) with switches (SW7 to SW1) and second transistors (M7 to M1) in off-state, the presence or absence of an identification current input is detected by means of identification current detection units (DI7 to DI1); and a second process in which, with respect to a slave in which the identification current input has been detected, subsequent generation of the identification current output is stopped and the first process is repeatedly implemented, and, with respect to one slave in which the identification current input has not been detected, an address is allocated. The communication system (1) is further configured to be able to implement the address allocation process while eliminating the slave for which the address has been allocated.
