PROBLEM TO BE SOLVED: To enable the change of setting of data accumulation processing without correcting a control program.;SOLUTION: This data accumulation device is adapted so that an MPU 5 executes, according to a data accumulation program 13 stored in a memory part 14, data accumulation processing in reference to a data accumulation processing parameter described in a data expansion definition table 17 stored in a data storage part 6. According to this, since the setting of data accumulation processing is changed by changing the parameter in the definition table 17, the setting of data accumulation processing is easily changed without performing the rewriting work of the data accumulation program 13.;COPYRIGHT: (C)2005,JPO&NCIPI
