Abstract
In control system for communication between units, each unit stores an adjacent-unit identifying number fixedly corresponding to each unit adjacent to one of the units, and forms a relative address, the relative address of the originating unit being 'nil' and the relative address of the destination unit being expressed by a set of adjacent-unit identifying numbers of all units provided on the communication path between the originating unit and the destination unit, excluding the originating unit and including the destination unit, the signal message routing being executed in such a way that, when the received destination address is 'nil', the unit receiving the message is determined to be the destination unit, and when the received destination address is not 'nil', the unit receiving the message transfers the message to the next-stage unit, whereby a simple addressing process is realized.
