<p><P>PROBLEM TO BE SOLVED: To execute simulation by preventing occurrence of memory leak even when a unit capacity of a communication frame acquired through high-speed communication is larger than a unit capacity of internally-processable data. <P>SOLUTION: A data acquisition device 30 acquires multiple communication frames consisting of a set of input values, applies data compression processing within the communication frames and data compression processing between the communication frames to each of the acquired communication frames, and records the communication frames after the data compression processing in a first storage part 33. A performance reproduction device 40 restores the recorded communication frames after the compression processing to the set of input values before compression processing in accordance with time information, uses the restored input values to trace a performance state of a facility on the basis of time shown in the corresponding time information, and displays the traced performance state on a screen, separately from the performance state of the facility. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
