<p>PROBLEM TO BE SOLVED: To provide a two-wire type communication system that can read data intermittently received in timing surely matched with the data transmission time and can be configured at a low cost. SOLUTION: In the two-wire type communication system where a main body device 2 supplies operating power to a remote commander 3 and transmits data thereto, the main body device 2 is provided with a power supply means 10 that supplies the operating power for a 1st prescribed time, a forced OFF means 11 that stops supply of the operating power and transmission of data for a 2nd prescribed time, and a data transmission means 12 that transmits the data in the unit of one bit for a 3rd prescribed time. The remote commander 3, on the other hand, is provided with a state change detection section 22 that detects stop of the operating power and a data reception means 23 that reads the data after a lapse of a 4th prescribed time from that point of time.</p> |
