Abstract

PURPOSE:To elevate a circuit efficiency by transmitting from each terminal station as to only whether there is a transmission telegram or not subsequently to polling against the first polling, so that the main station sends out the polling only to each terminal station which requesting for transmission. CONSTITUTION:The main station 1 executes the polling to plural terminal stations T1-Tn, respectively, in order to inquire whether there is a transmission request or not, and only the terminal stations T1-Tn having a transmission request in response to this polling add a response containing an address of the own station, subsequently to the polling sequence, and execute the transmission. Subsequently, the main station 1 designates an address of the response, and executes the polling for permitting the transmission. And, only a terminal station that has been designated transmits a transmission telegram after the polling sequence.
