The controller repeats transmitting a request signal indicative of a predetermined probability. Upon receiving the request signal, the terminal sends, at the probability indicated by the request signal, a response signal including the identification information uniquely allocated to the terminal. Upon receiving the response signal, the controller sends a notification signal with reference to the identification information included in the response signal. The terminal judges whether or not a response has been completed, on the basis of the received notification signal. The terminal sends no response signal in response to receiving the request signal once after judging that the response has been completed. The controller prepares the next request signal indicative of the probability not less than that indicated by the previous request signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Network system","description":"The network system includes a controller and a plurality of terminals.
