ABSTRACT:
A multiple node network includes a plurality of terminal nodes. A management node manages the terminal nodes. A bus connects the respective terminal nodes and the management node to one another. The respective terminal nodes and the management node communicate with each other using a frame that includes at least an identifier field and a data field. The data field has a discriminative number. Each terminal node transfers the frame to the management node. A contention between the terminal nodes is arbitrated by comparing the respective identifier fields of the terminal nodes. When the arbitration fails, each terminal node repeatedly transfers the frame to the management node after a delay time that is unique for the particular terminal node and that is calculated based upon the discriminative number in the data field.
