Abstract
A communication system is configured to be capable of executing an address assignment process including: a first process for detecting presence/absence of an identification current input by means of an identification current detection unit when a constant current supply has generated an identification current output with a switch and a second transistor in an off state; and a second process for repeatedly executing the first process while, with respect to a slave among the slaves that has had the identification current input detected therein, stopping generation of the identification current output thereafter, and assigning an address to a single slave among the slaves that has not had the identification current input detected therein, and is also configured to be capable of executing the address assignment process while excluding a slave among the slaves that has had the address assigned thereto.
