<p>PROBLEM TO BE SOLVED: To provide a communication system in which a communication error caused by setting an address occurs hardly even when a slave unit based on a different communication system also exists.SOLUTION: A master unit 20, plural slave units 10 and relay master units 30, 31 are provided as nodes constituting a communication network 1. The slave units 10 can select a communication method used for communications from plural kinds of communication methods. Slave units which select a radio communication method are set as radio slaves 11, and slave units which select a power line carrier communication method are set as wired slaves 12, 13. The relay master units 30, 31 are connected between nodes having different communication methods, and configured to relay communications between the nodes having the different communication methods. The master unit 20 is configured to allocate individual addresses to the radio slave units 11 connected to one another under the control of the master unit 20 and the wired slave units 12, 13 connected to each other under the control of the relay master units 30, 31.</p> |
