PURPOSE:To broadcast partially different data in the information communication system where each station is coupled by LAN and the simultaneous multi- address communication function is provided for 1:N or N:N data transmission. CONSTITUTION:A transmission station 11 takes out common data by the request of simultaneous multi-address transmission (S1), and peculiar data different by reception stations are added to this data (S2), and data is transmitted as simultaneous multi-address data (S3). Reception stations 12 to 1N receive the data (S4) and extract common data and peculiar data destined for stations themselves (S5) and transmit data to their sub-slave stations 22 to 2N (S6). Thus, the simultaneous multi-address transmission where reception stations receive the same data is realized, and each reception station extracts common data and peculiar data destined for the station itself from received data to obtain data partially different by the station.
