<p>Communication stations(3) whose own addresses coincide with a destination address of communication data(31) received via data transmission lines(5) and whose write enable/disable states of their own addresses stored in their address/flag memory(21) are in their write enable states can update their own addresses to variably set address values of the communication data, then update their own address write enable/disable states to their write disable states, then execute predetermined calculations for the variably set address value in the communication data(31), and then transmit the communication data(3) whose variably set address value has been rewritten into the variably set address value obtained by the calculations to succeeding stations(3) so as to circulate between a plurality of communication stations(3) sequentially. <IMAGE></p> |
