PURPOSE:To provide a flexible system, by rewriting the processing step of each processor forming a hierarchy with a high host computer via an RAM. CONSTITUTION:A picture data from a plant 8 is fetched to the host computer 2 and transferred to a parent computer P-CPU1, which stores sequentially the data to blocks A1-An corresponding to the RAM9. An input request IRQ is generated to the host computer 2 or the P-CPU1 attended with the establishment of data at the plant 8. The host computer 2 or the P-CPU1 operates a receiving program at the generation of IRQ, receives the data and generates a receiving end signal at the end. The P-CPU1 stores sequentially the data to the blocks corresponding to the RAM9 determined in advance after the receiving of the data. |
