<P>PROBLEM TO BE SOLVED: To provide a data relay control device capable of executing inter-link transfer setting for transferring data in a shared memory area from a communication node of one network to a communication mode of another network without any human labor in a control system in which a plurality of networks performing cyclic transfer of shared memory type are present. <P>SOLUTION: The data relay control device includes: a plurality of nodes 31 and 32 connected to a plurality of networks respectively; a base for connecting between the plurality of nodes 31 and 32 with a communication channel; an interlink transfer control part 35 for transferring data from a node to be connected to one network to a node to be connected to another network on the basis of interlink transfer setting; and an interlink transfer setting generation part 33 for generating interlink transfer setting on the basis of label allocation information that includes a label attached to a memory area for use in a program, and flag information indicating whether the label is an operation for storing data before computation or an operation for becoming a destination of data after the computation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
