The present disclosure relates to a polling method of communication system configured to reduce a polling time by receiving responses from a plurality of auxiliary devices using one time of response request signal by a main device during polling, the method including, requesting, by a main device, transmission of response request signals from a plurality of auxiliary devices connected to the main device (request step),
determining whether each of the plurality of auxiliary devices is a response object after receiving the response request signal (response object determination step),determining a response order by each of the plurality of auxiliary devices that has determined itself as the response object (response order determination step), andresponding, by itself, to the response request after lapse of waiting time in response to its response order (response step). |

1. A polling method of communication system, the method comprising:
requesting, by a main device, transmission of response request signals from a plurality of auxiliary devices connected to the main device (request step); determining whether each of the plurality of auxiliary devices is a response object after receiving the response request signal (response object determination step); determining a response order by each of the plurality of auxiliary devices that has determined itself as the response object (response order determination step); and responding, by response object auxiliary devices, to the response request after lapse of waiting time in response to its response order (response step). |
