PROBLEM TO BE SOLVED: To enable communication equipment having a communication function by a specific protocol to communicate with electrical equipment having no communication function by the specific protocol.SOLUTION: A first protocol communication part 101 and a first protocol communication part 201 communicate by a first protocol. A second protocol communication part 102 and a second protocol communication part 301 communicate by a second protocol. A third protocol communication part 302 and a third protocol communication part 401 communicate by a third protocol. A relay part 304 allows the third protocol communication 302 to transmit second equipment control information received by the second protocol communication part 301 to second electric equipment 400, and allows the second protocol communication part 301 to transmit second equipment state information received by the third protocol communication part 302 to a communication adaptor 100. |
