Abstract
The present invention discloses a data transfer method wherein data is broken up into N datablocks (where the number N is a natural number) for transfer from a first node to a second node on a bus system each of whose nodes is assigned a node identifier, wherein the data transfer method comprises, prior to transfer of the datablock, a step in which a control node (1) issues to the second node a datablock reception instruction containing therein a node identifier of the first node and (2) issues to the first node a datablock transmission instruction containing therein a node identifier of the second node, thereafter, a step in which the datablock transfer from the first node to the second node is executed, after the datablock transfer is completed, a step in which the first node notifies the control node of a result of execution of the datablock transfer processing, and a step in which the second node notifies the control node of a result of execution of reception processing on the datablock.
