<P>PROBLEM TO BE SOLVED: To improve the synchronization accuracy, without making the performance of other communications deteriorate, in synchronizing the times by timers of a plurality of apparatuses that are interconnected, using a network and have a master-slave relation. <P>SOLUTION: This system comprises a connecting device (master) 1, between nodes and a plurality of processor nodes (slaves) 41-43 connected to the connection device between nodes, and synchronizes copy clocks 411-431, built in respective processor nodes with a master clock 3 of the connection device between nodes. The connection device between nodes comprises a time set command generating means 14 for generating the time set command based on the master clock, a communication data storage means 11 for storing the communication data, a communication data interval calculating means 13 for calculating the interval of the communication data, a time set command inserting means 12 for inserting the output of the time set command generating means into the output of the communication data storage means, and a transmittablity determining means 15 for determining the communication data receivable states of the processor nodes. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
