Communication method and communication system

摘要

The communication system conducts communication among nodes N1 to N4 that form a communication network of bus type by using set communication parameters. The communication system includes one master node N1 selected from among the nodes N1 to N4; and one or more slave nodes N2 to N4 that are nodes N2 to N4 other than the master node N1, the one or more slave nodes logically star-connected to the master node N1, each of the one or more slave nodes conducting communication with another node N2 to N4 via the master node N1 by using communication parameters negotiated with the master node N1. <IMAGE>
